This is really inappropriate.
Your negligence may cause great economic losses.
After the full-time surveyor sets the main shaft line and completes the elevation control point, the technician should master the basic skills of the pendant.
If you don’t give repeated advice, it’s not surprising that it is 3 ~ 5mm.
As technicians, they should also participate.
In addition, when the two-point height difference is large, the general error of measuring oblique distance and measuring two-point height difference calculated by Pythagorean chord theorem is small.
After all, it saves the artificial increase of joints during steel bar batching, resulting in the waste of materials.
In front of the owner and the supervisor, no matter how harmonious you feel, you can never tell the truth when you don’t follow the rules.
For example, the selection of test pieces for mechanical property test of reinforcement can not be simply intercepted from the end of reinforcement, Generally, it is necessary to cut off about 1m before sampling, because it is necessary to eliminate the impact on the end during hot rolling of reinforcement production, and pay attention to the purpose of on-site sampling and re inspection, so that each group of specimens can be truly universal and representative.
If you set up your own concrete mixer, the cement is generally accrued according to the budget.
Another reason is that the technical disclosure is to enter the handover data, so it is absolutely not allowed to violate the specifications.
After a fait accompli, it is the most disgusting thing for project managers and operators to pick up problems with instruments..
At present, the survey and setting out on the construction site is not as formal as the measurement distance with front ruler, back ruler, reading and records in the school survey practice.
If the previous step is not rechecked, the next step cannot be carried out; The measurement steps shall be checked.
Hehe, what do you mean? Think about it yourself.
The sampling and inspection of incoming raw materials are jointly completed by the sampling witness, the materialman and the supervisor in some formal units.
Although it is not completely right, it can be regarded as a magic weapon for the self-protection of Surveyors: “the triangle should be small and the line should be thick”, which means that when drawing the red triangle for the elevation, don’t draw it too large, and the ink line should be thicker when playing the ink line.
If you want to improve, you should take a look at the operation of workers, see what has not been done according to the book, and what has a bad impact on the quality.
There is another saying spread on the construction site.
Remember the key points that the teacher said when learning measurement: first the whole, then the part; Re check frequently.
The sand is generally 0.5 cubic meters per cubic meter, and the stone can be accrued according to 1 cubic meter per cubic meter.
The material plan is the same as the material plan.
In this way, you will be confident when you go to the site for inspection during construction, and you can find problems at once.
Generally speaking, the common problem of technical disclosure is that there are many copies and specifications, and not many can guide the construction.
Of course, for new technicians, it’s best to strictly follow the specification requirements.
As long as you pay attention, you can raise the number very accurately.
As a site technician, you must be proficient in the use and operation of level, theodolite, ink bucket and plumb bob.
If you stay on the site for a long time, you can know what is the key.
On site quality inspection, on-site quality inspection, formwork size and elevation inspection, etc.
But remember what the standard practice is.
The first advantage is that they feel at ease.
From | the copyright of construction technology belongs to the original author.
Second, it’s always good to give others the impression that they are serious.
Cement samples must be mixed from any 10 bags according to the specification requirements and then submitted for inspection.
At present, 11g101 atlas is generally used in reinforcement design.
I have just learned the course of reinforced concrete, which should be faster than others.
You can’t ask the project manager to allocate enough professionals to accompany you in positioning, But you must be careful and run back.
Look at the level gauge, the ruler may not be who.
After the concrete mix proportion sheet is issued, it is adjusted according to the actual consumption per cubic meter.
The things learned in school and the knowledge of reading specifications and procedures by rote are far from being remembered as well as the actual experience.
I can let others say that your disclosure is a rigid copy and can not guide the specific construction, but it is better than letting others read and say that you don’t understand and speak jargon.
He can’t always rely on the theodolite, which is impossible and unrealistic.
The quota is prepared by integrating various project categories.
It should be noted that the front and rear pitching of the tower ruler has a great impact on the observation results.
It is often the foreman and technician who go to set out, and then the site calls a worker to help.
The advantage is to provide the laboratory with the data closest to the real situation, so that the mix proportion sheet issued is more economical and scientific.
Don’t look at the content of the budget quota.
The content in some quota subitems can’t be used in actual construction, but some are not enough.
For example, ceramic tile marble, the design has given dimensions and specifications, You can actually arrange the number of half bricks, including the number of bricks to be cut.
The important thing is to control in advance.
My experience is that when I am not clear about the construction process and construction steps, I still copy more specification requirements.
If the steel supply channel has a reliable guarantee and has a high reputation of long-term cooperation, the steel bar specimen of this specification can also be taken at one time on one steel bar.
Setting out is the first thing to say.
When raising reinforcement materials, pay attention to the amount of reinforcement joints.
After all, some can be done but can’t be written out.
Technical disclosure talk about technical disclosure.
seem simple, but in fact, the accumulation of experience is also very important.
Whether the budgeter mentions it or not, as a technician, you must calculate the actual consumption by yourself.
Surveying and setting out is particularly important during construction.
Another thing is that it is difficult for non professionals to grasp the point under the tower ruler.
The elevation on the construction site is generally a technician’s business.
Relatively speaking, the positioning and setting out of residential and office buildings is much simpler, and the industrial plant is much more complex.
You must write it down and make a summary.
When setting out and measuring the size, it is necessary to avoid using a small ruler one foot one foot (3m and 5m are commonly used on the construction site) to avoid error accumulation.
