Today, the editor collected and organized various safety points in pile foundation construction to share with everyone.
(2) The construction site should be leveled and compacted, and there should be no high-voltage lines within 5m around the pile driver.
If necessary, the pile frame shall be placed on the ground.
The working area should have obvious signs or fences, and unauthorized entry is strictly prohibited.
The construction of soil compaction piles and partial soil compaction piles generally includes: driving pile construction, vibration sinking pile construction, static pressing pile construction, vibration punching pile construction, rotary spraying pile construction, etc.

(7) During operation, if the shutdown time is long, the pile hammer should be dropped and cushioned properly.
(10) When the wind force exceeds Level 7 or there is a severe tropical storm alarm, the pile driver shall be stopped along the wind, and the cable wind rope shall be added.
The main precautions during the construction of manually excavated piles are: (1) Construction workers should wear labor protection equipment
.
Nowadays, the construction of large buildings is becoming increasingly common, and the increasing scale of buildings requires higher quality and safety requirements for foundations and pile foundations.
Mainly used for dense soil layers or weathered rock layers with no or a small amount of groundwater; It is also used in areas where mechanical drilling is not feasible or difficult, and hydrological and geological conditions permit.
(6) The electrical equipment of the pile driver should have good insulation and should be protected by grounding (or neutral connection).
The power cables should be collected and placed by a dedicated person, and should not be dragged or placed anywhere.
(5) Before operation, the pile driver should be inspected to ensure that the equipment is intact, the bolts are fastened, and the safety device is effective before starting.
(11) After the operation is completed, the pile driver should be parked on a solid and flat ground, braked and wedged firmly, and the power should be cut off.
1、 Safety requirements for construction of soil compaction piles and partial soil compaction piles.
(3) When moving the pile frame, the pile hammer should be placed to the lowest position, and the movement should be slow, with unified command, and measures should be taken to prevent tipping.
It is strictly prohibited to suspend the pile hammer for maintenance.
(9) In case of severe weather conditions such as force six or above winds, thunderstorms, heavy fog, and snow, operations should be stopped.
The use and scrapping standards of the steel wire rope shall be in accordance with the Code of Practice for Inspection and Scrapping of Steel Wire Ropes for Cranes (GBT5912).
(4) The steel wire rope of the pile driver winch shall be lubricated to prevent dry friction.
(8) During the construction process, the operation of the pile driver should be strictly carried out in accordance with the safety code “Safety Technical Regulations for the Use of Construction Machinery” (JGJ33).
2、 The safety requirements for manual excavation pile construction refer to manual excavation of soil and on-site pouring of reinforced concrete piles.
The main safety precautions during the construction process include: (1) pile machine operators should undergo training and examination, obtain operation certificates before starting work.
