Later, the causes of the problems were summarized.
It must be done well.
During the construction process, all materials mobilized must meet the design requirements, industrial standards and national specifications.
The project department shall timely hold various meetings, such as quality analysis meeting, formulate rectification measures, rectification time and responsible person, etc.
One person’s energy is limited, otherwise we will not have a division of labor in various posts.
In the decoration construction stage, early planning is very important.
Many good measures and schemes can not be implemented smoothly, and the executive power must be improved.
Although this work is very simple, it can’t be done without special personnel.
NOCITCE changed the push rule because of WeChat official account.
For the next project, we should measure and control from the scheme, and check and block all kinds of pipelines within the slope before earthwork excavation.
After the materials enter the site pass the self inspection, they shall be reported to the supervisor for acceptance, and the materials shall be subject to witness sampling and sampling inspection.
After the site plan comes out, the materials must be stacked according to the requirements of the plan and cannot be placed at will.
In the future, we must assign work to people and implement accountability.
Everyone can’t be responsible for one thing.
2.
//Wechat public account setting prompt/// The official account is official.
The first aspect is that the management level of our own project managers needs to be improved.
Construction is a process management.
In the future construction, we must strictly control the concrete elevation.
Many common quality problems in construction can be pre controlled.
If you don’t want to miss the highlight of this official account, please put the public number of construction technology as the star sign and click “collect”, “look at” and “Zan” at the end of the text, so that each new article will appear in the subscription list at the first time.
In the process of earth excavation and backfill construction, campus road cleaning and dust control are the top priorities.
Later, after several rectifications, we made a special construction scheme and achieved results.
Only by grasping the process can we build a qualified project.
5.
An obvious problem in our project decoration is that the cooperation of various disciplines is not in place.
This is what we need to pay attention to in the future project construction.
We didn’t do this work in place at the beginning.
On the other hand, we must pay attention to various detail construction in the future construction.
As long as the foreman and quality inspector are a little more careful, check the drawings and elevation control points, and measure them in the construction, We can correct the problem in time.
This thing gives us an inspiration.
For another example, after the formwork removal of the wall column, it is found that there are local vibration leakage of individual beams and columns, large deviation of wall flatness, inclusion, local mortar leakage at the external corner of the wall, and inadequate concrete maintenance.
The daily work is complicated, the content is heavy and the task is heavy.
The materials entering the site must be accompanied by the quality assurance certificate, certificate and relevant test report.
3.
There was no prior communication on the stacking and location of materials, resulting in random stacking of materials.
For example, in order to meet the ceiling elevation, the layout of all professional pipelines such as water, electricity, ventilation and heating must meet the elevation requirements.
At the same time, the foreman shall explain the location and stacking requirements to the material group before the materials enter the site to avoid disorderly stacking..
The foreman and the quality inspector must be required to start the construction after comparing the drawings one by one.
As long as we take measures and process supervision in place, there will be no problems.
Safety production has always been the top priority of project management.
The project department is a whole.
We can only remind others while doing our own post work well, And do experience exchange to learn from each other.
After the materials enter the site, we must accept the appearance quality, specification, size and model of the materials, and never release the materials with problems.
Finally, the project department can only take the way of severely punishing the hydropower team to attract its attention and completely solve this problem.
In the decoration construction, the contradiction between the civil engineering specialty and the hydropower specialty is more prominent, such as opening and blocking holes in the wall, which basically runs through the whole process of decoration.
It shows that the mobilization acceptance of materials is very important.
There is a problem of smashing the wall.
Earthwork excavation and backfill construction During the excavation of the 3# building foundation pit of the project under construction, the northeast corner slope collapsed due to heavy rain.
If there is no certificate, the materials without quality assurance data shall be rejected.
As long as there is a problem in a certain link, it will cause losses.
After the later project management personnel made local adjustment plans on site, the requirements were basically met after rectification.
For example, after the completion of concrete construction, it is found that the elevation is too high, resulting in the occurrence of chiseling in the later stage, and there is the problem of one step more construction.
However, the site is sometimes chaotic, which has something to do with the narrow project site and the awareness level of our project managers.
In view of this problem, we timely hold a meeting to analyze the causes and formulate countermeasures, such as the formwork must be cleaned and brushed with release agent, sponge strips at the formwork joints, encryption of the secondary keel of the formwork, etc, In addition, the concrete curing shall be carried out at a fixed person and time, the beam reinforcement shall not be bound until the concrete joint is chiseled, the slab reinforcement shall not be bound until the beam reinforcement is accepted, and the reinforcement team shall be equipped with reinforcement watchers during concrete pouring.
When the wall is vibrated and the masonry mortar cracks, there will be horse shaped cracks in puttying in the later stage, which makes it very difficult to maintain in the later stage.
Special work must be in the charge of special personnel.
The cooperation of various disciplines is very important in the decoration stage.
Underground structure construction During the straight thread construction, it is found that the section of some incoming threaded reinforcement is oval, which also has a great impact on the connection of straight thread of reinforcement.
Building construction can not be done by one person.
The project is the chief of staff of the project department.
Building construction is a rigorous and meticulous work, which must be fully coordinated by all parties.
Only when everyone cooperates well can the work be done smoothly.
A person can’t finish the work neatly without the cooperation of others.
They can be used in the project only after the test results are qualified.
Especially in the project, the construction unit changes a lot in the later stage, and there are often holes that have just been blocked, because hydropower and other disciplines have to reopen or open holes in other places, and the walls that have just been built are removed.
There must be a person who is mainly responsible for this work.
The drainage pipeline of the May 4th gymnasium leaked, the edge hardening of the slope was not in place, and the water from the roof drainage pipeline of the May 4th gymnasium was directly discharged on the slope ground, and the water penetrated into the slope.
There has been no safety accident from the beginning of construction to the end of the whole project.
In fact, this problem can be easily solved.
Because the reinforcement is not round, the sleeve cannot enter when it is sleeved to more than half, so the reinforcement can only be replaced.
The content is for reference only! 1、 Summary of the previous project 1.
4.
The construction of above ground structure has encountered various common quality problems in the construction of above ground structure.
In the construction of opening the hole, the project department basically emphasizes that it is not allowed to smash the hole every day, and only machine cutting is allowed.
The chief engineer of special parts shall watch the site in person to avoid mistakes.
However, the management personnel of the hydropower team do not explain the workers in place after the meeting and disclosure, and there is always the phenomenon of smashing the wall.
How do they clear the way of thinking and grasp the key points? Let’s have a look at the work report of the chief engineer of the project.
In order to effectively control safety production and make “alarm bells ringing and accidents zero”, we have done a lot of work to make safety production always under the control of the project department.
Before the installation of various pipelines, we conducted a comprehensive arrangement of pipelines, but the elevation of some places still failed to meet the standard during on-site construction.
Star setting: enter the official account home page, click on the top right corner, click “set star”, and the official account of the yellow star (Android and iOS user operation) will be presented next to the public name.
For various problems in structural construction, we should consider them from two aspects.
With regard to safe and civilized construction, the quality of safe production and civilized construction on the construction site is an important symbol of enterprise construction.
This involves the division of work of the project department.
Cooperation is very important.
