Description

Prefabricated pile hanging method

technical field

The invention relates to a prefabricated pile construction method, in particular to a prefabricated pile hanging method.

Background technique

Traditional prefabricated pile construction methods mainly include static pressure method and hammering method, but these two methods will cause damage to the pile body on the one hand, and on the other hand will produce a soil squeezing effect, which will affect the construction quality of the pile itself and the surrounding environment. In order to solve these problems, the engineering field has developed an embedded construction method through pre-drilling and then implanting prefabricated piles. Wherein, the pile body needs to be hoisted when the prefabricated pile is implanted.

In the existing method of pile lifting, the use of mechanical arms or mechanical claws to lift the prefabricated pile will cause damage to the pile body of the prefabricated pile. Picking up the prefabricated pile will also cause damage to the pile body of the prefabricated pile, and the operation is more loaded down with trivial details.

Contents of the invention

The technical problem to be solved by the present invention is to provide a simple and easy prefabricated pile-hanging method which does not damage the pile body during the pile-hanging process.

The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a method for hanging piles by prefabricated piles, the specific steps are:

A, select a plurality of steel wire ropes, the two ends of the steel wire ropes are closed rope rings; b, after one of the steel wire ropes selected in step a is wound around the prefabricated pile body twice, the rope ring at one end of the steel wire rope is removed from the Pass through the eye of the rope ring at the other end; c, wrap the remaining steel wire rope around the prefabricated pile body in step b, and hang all the passed rope rings on the hook; d, slowly lift the hook, Until all the wire ropes lock the prefabricated piles; e, continue to lift the hook to lift the prefabricated piles.

Compared with the prior art, the present invention has the advantages that: the method uses the steel wire rope to wrap the prefabricated pile body, slowly lifts the steel wire rope with the hook, and after the steel wire rope locks the prefabricated pile, continues to lift the hook to lift the prefabricated pile, and the whole construction The process is simple and easy, and due to the flexibility of the wire rope, no damage will be caused to the prefabricated pile body.

Preferably, there are two steel wire ropes, the steel wire ropes are locked behind the prefabricated pile, distributed symmetrically to the axis of the prefabricated pile, and the lengths of the two steel wire ropes beyond the prefabricated pile body are equal. The prefabricated pile body is under stable force, and it is not easy to shake when hoisted.

Preferably, there are three steel wire ropes, and after the steel wire ropes are locked to the prefabricated pile, they are evenly distributed around the axis of the prefabricated pile. The prefabricated pile body is more stable in force, and the prefabricated pile can still be hung after one of the wire ropes breaks accidentally.

Preferably, the length of the rope ring is 20 cm to 50 cm. According to the diameter of the steel wire rope, a suitable rope ring is set. When the rope ring is too large, it will be difficult for the steel wire rope to lock the prefabricated pile body.

Preferably, the length of the steel wire rope is 200 cm to 600 cm. Select the appropriate wire rope according to the size and length of the prefabricated pile, and when choosing wire ropes of different lengths, interference between the wire ropes can be prevented.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

The specific steps of this prefabricated pile hanging pile method are: a, select a plurality of steel wire ropes 1, and the two ends of the steel wire ropes 1 are closed rope rings 11; After two laps at 1/5 of the distance from the top, the rope ring 11 at one end of the steel wire rope 1 is passed through the eye of the rope ring 11 at the other end; c. Wrap the remaining steel wire rope around the prefabricated pile by the method of step b Stand near the place, and hang all the loops 11 that pass through on the hook; d, slowly lift the hook until all the wire ropes 1 lock the prefabricated pile 2; e, continue to lift the hook, and lift the prefabricated pile 2 . The whole construction process is simple and easy. Wherein, when lifting the hook slowly, due to the weight of the prefabricated piles, all the steel wire ropes 1 will be gradually corrected, so that all the steel wire ropes 1 are locked to the prefabricated piles 2 .

Among them, the number of steel wire ropes 1 is preferably 2 to 5. When there are 2 steel wire ropes, the position of the steel wire ropes can be adjusted during the process of slowly lifting the hook in step d, so that the 2 steel wire ropes are locked behind the prefabricated pile, distributed symmetrically with the axis of the prefabricated pile, and the two steel wire ropes exceed the prefabricated pile body. are equal in length. When there are 3 steel wire ropes, the position of the steel wire ropes can be adjusted during the process of slowly lifting the hook in step d, so that after the 3 steel wire ropes are locked on the prefabricated pile, they are evenly distributed around the axis of the prefabricated pile, and the force on the prefabricated pile body is more stable. And the prefabricated pile can still be hung after one of the wire ropes breaks accidentally.

The thickness of the steel wire rope 1 is selected according to the weight of the prefabricated pile 2, and the diameter of the steel wire rope 1 is generally 5 mm to 30 mm. The length of rope ring 11 is set according to the size of wire rope 1 diameter, is generally 20 centimeters～50 centimeters. The length of the wire rope 1 is selected according to the size and length of the prefabricated pile 2, and the length is generally 200 cm to 600 cm.

This method adopts the steel wire rope 1 as the wrapping object because the steel wire rope 1 has good flexibility and will not cause damage to the prefabricated pile body.
