The broken pile head construction team tells you the requirements of the broken pile head constructi

During construction, piles need to be driven underneath in order to ensure the stability of the building
So what are the requirements of the construction specifications for broken pile head? Let's have a look

1
The pile head can be broken only when the hardness of the concrete surface reaches certain conditions, and soft breaking, blasting and other methods cannot be used
2
The reinforcement shall not be damaged during ring cutting
After breaking, the pile top shall remain slightly convex
3
When the pile head is broken, the reinforcement protection measures shall be taken, and the reinforcement of the pile head shall not be bent
4
After the pile head is broken, no concrete shall be left on the pile top

What should we pay attention to in building piling
1
The construction personnel must do a good job in safety, wear safety protection tools during construction, and work with certificates

2
Before construction, the machinery shall be carefully inspected to see if there is any fault, and shall be repaired and maintained in time
During construction, the cables to be used shall be carefully checked to ensure safety before they can be used

3
Piling personnel on site shall also wear work cards, wear uniform clothes, and wear safety helmets to ensure safety

4
Guardrails shall be set around pile driving and obvious signs shall be made to prevent people from watching or approaching the construction site

5
If piling is required at night, the site lighting shall be sufficient to ensure construction safety
If the construction of pile hole is suspended, the surface shall be covered and obvious warning signs shall be made to prevent people from approaching

6
In case of water seepage from the shaft wall during pile driving, it must be drained in time

7
If the distance between pile foundations is relatively small, skip excavation shall be adopted, and the distance between pile holes shall not be less than 6m

8
If the depth of pile hole is more than 10m, air supply device shall be equipped, and air supply shall be started 5 minutes before construction
If there is toxic gas in the hole, conduct gas detection again after ventilation for a while

Summary: the above is about the requirements of the construction specifications for broken pile head
I hope it will be helpful to you! Pile driving needs to pay attention to many details, so you can refer to the above contents during construction
