After the review, the supervisor shall sign the comments on the review form, affix the official seal, and return it to the construction unit.
If at least half of them are called embedded, they also need to be concealed..
During the joint review, our documenter will record the joint review of drawings (I) Submit it to the personnel of each unit participating in the joint review for signature.
The general report of foundation pit monitoring (original or copy) is the summary table of each settlement and displacement.
After being confirmed by the technical director of the project, it shall be made in n copies (at least one copy for each participating unit + the number of copies required by the construction contract) according to the actual and needs.

The design unit also needs to affix the seal.
Concept of concealment: in the process of doing, some still exist permanently after completion, but those that cannot be seen need to be concealed.
Learning knowledge is the right way.
The seal and signature procedures of each unit must be complete.
Foundation pit monitoring: 1.
The monitoring results of the horizontal displacement of the top of the foundation pit supporting structure, and the records of the movement of the front, back, left and right of the edge of the foundation pit (horizontal direction) engineering piles (static piles) Procedure: joint review of drawings – pile position number – Preparation of driving route map of pile driver – Preparation of pile foundation construction scheme – mobilization of pile driver – mobilization of personnel – mobilization of pipe pile and pile tip and submission of materials for review – quality and technical disclosure – Measurement and setting out (positioning and review of engineering baseline) – commencement application report – pile test – pile driving – pile foundation detection (bearing capacity: high strain static load) – earth excavation – pile cutting (up to the design pile top elevation) – after earth excavation, recheck the pile foundation and draw the corresponding pile position offset diagram.
The construction unit entrusts a third party to monitor at the beginning of foundation pit excavation and ends after the basement outer wall or foundation pit earthwork backfilling.

Anchor bolt construction process: drilling – placing anchor cable – grouting – anchor cable tension test shall be conducted when grouting is 28 days Foundation pit support works are: crown beam construction process of supported earthwork: reinforcement installation – formwork installation – concrete construction – formwork removal – concrete appearance waist beam construction process: formwork installation – reinforcement installation – concrete construction – formwork removal – concrete appearance cast-in-place pile process: hole excavation – reinforcement – concrete pouring – 28 day core drilling test (strength and integrity) Shotcrete surface process: soil nailing drilling – soil nailing grouting tension test – slope laying reinforcement mesh – welded reinforcement (reinforcement mesh and soil nailing are welded as a whole) – shotcrete on-site inspection items: 1.
Text content and process of forming construction scheme: contents prepared by the project technical director Signed by the preparer and the technical director of the project, and sent to the company for review and stamped with the official seal After returning to the construction site, it shall be submitted to the project manager for review and submitted to the supervision company.
The drawings will be approved Review process: 1.
Let’s study together! Unit project commencement report: checklist of legal construction procedures in the early stage of project construction, quality management inspection records on the construction site, and binding sequence of unit project commencement application report and construction scheme: 1.
The complete pile is class I pile, the basically complete pile is class II pile, the incomplete pile is class III pile, and the broken pile is class IV pile.
Core drilling sampling of cast-in-place pile (the core of the cast-in-place pile shall be extracted when the concrete is poured for 28 days) the purpose is to test the strength of the cast-in-place pile concrete and the integrity of the cast-in-place pile.

As the saying goes: life will treat you with what attitude you take, Young people are more open-minded to consult their predecessors on the construction site.
The records (I) and (II) will be reviewed After binding, first go to the company to affix the official seal and legal person seal, and then to the supervisor, the construction unit and the design unit to affix the legal person seal and official seal.
If there is class III pile, it is necessary to supplement the pile After passing the test and Issuing the test report Organize the acceptance of pile foundation.

The basement construction process: joint review of drawings → construction scheme → commencement report → technical disclosure → earthwork excavation → cushion cap → brick formwork → pile core concrete → earthwork backfilling of bottom plate → cushion cap → waterproof layer → protective layer → cushion cap bottom plate → Exterior wall of basement negative second floor (interior wall and column of basement negative second floor) → beam and slab of basement negative first floor → exterior wall of basement negative first floor (interior wall and column of basement negative first floor) → basement roof → pouring of basement post cast strip → waterproof and protective layer of basement exterior wall → waterproof and protective layer of basement roof → drawing of basement waterproof effect drawing → basement structure detection → earthwork backfilling of basement exterior wall → retrieval of all detection reports of basement → grade evaluation of basement concrete → sub divisional acceptance of underground structure.
Anchor bolt (soil nail) tension test (on-site tension after 28 days of grouting) to detect whether its anchorage strength meets the design requirements.
After the joint review, take it back to the office of the project department together with the record (II) and print the record (II) again.
2.
After receiving the construction drawings, the supervision unit and the construction unit shall look at the problems existing in the drawing process, summarize the problems separately by discipline and division, and record them in the drawing joint review record (II) Then both parties exchange problems with each other and remove duplicate parts.
The supervision unit shall keep one copy for its own record After the construction unit receives the scheme, it shall be kept by the documenter; note: in the process of scheme approval, any problem in any link of the company, project manager, supervisor and general supervisor will be returned to the construction site for rectification, and then rectified again, and then repeat the above approval process until all the schemes are approved.
For newcomers to the workplace, they are still very young, lack of on-site experience and have no place to show their enthusiasm.
(cast-in-place pile row pile construction) suitable for deep foundation pit mixing pile construction – earth excavation (suitable for Shallow Foundation) – anchor bolt construction– Anchor bolt tension test – waist beam construction and grading: Earth excavation – grading – soil nailing into the slope – laying reinforcement mesh on the slope and welding with soil nailing to form an integral reinforcement mesh– Shotcrete anchor cable construction process: drilling – placing anchor cable – grouting – anchor cable tension test shall be conducted when grouting is 28 days.
We should also remember that we must not be careless on principles and major issues! We have summarized the construction procedures of each sub item.
