Recording is required. The pile foundation does not need to be inspected, but there should be a large and small strain detection report. After the design requirements are met, the supervision engineer will accept the foundation steel bars and issue a foundation concrete pouring order.
Requirements for filling in foundation groove inspection records:
1. The acceptance time is the date of inspection and acceptance agreed upon by all parties.
2. The location, geometric dimensions, and trench bottom elevation of the foundation trench (pit) are all filled in according to the acceptance measurement records.
3. Use diagrams to illustrate the locations where the soil layer direction, thickness, and soil quality change.
4. Type, color and hardness and uniformity of the soil at the bottom of the tank.
5. Groundwater level and flooding conditions, etc.
6. If there are ancient tombs, cobalt wells, caves, cables, old house foundations, quicksand, etc., the location, elevation, treatment description, or change document number should be indicated on the map.
7. Inspection and acceptance opinions: indicate whether the foundation meets relevant requirements such as design and specifications. Whether it is consistent with the soil quality conditions in the geological survey report, the construction unit shall organize the geological survey department, design institute, construction, supervision unit and relevant construction personnel to participate in the trench inspection, and the inspection shall be recorded and signed. The next construction process shall not be carried out without groove inspection procedures.
Extended information:
Reinforced concrete cast-in-place piles are made by directly forming holes at the pile position on site, and then pouring concrete in the holes or placing steel cages and then pouring concrete. of piles.
1. Compared with the hammering method of sinking piles, the construction noise and vibration are much smaller;
2. Piles with a diameter much larger than those of prefabricated piles can be built ;
3. It can be used on various foundations;
4. The quality of construction has a great influence on the bearing capacity of piles;
5 , Because concrete is poured in muddy water, the quality of concrete is difficult to control.
