Abstract

The present invention relates to bored concrete pile technology fields more particularly to a kind of cast-in-situ bored pile to break a processing method, comprising the following steps: Step 1: verifying the interlayer position of bored concrete pile；Step 2: the depth in hole is up to the position of interlayer in one hole of centre drill of bored concrete pile；Step 3: going deep into a Grouting Pipe into hole, it is equipped with a sealing ring, the inner wall tight fit of sealing ring and the hole front ring week of the Grouting Pipe, Grouting Pipe is deep into interlayer, high pressure concrete is injected into interlayer, high pressure concrete squeezes out mud from interlayer；Step 4: being lifted up Grouting Pipe, while high pressure concrete is injected into hole, the final solidifying soil of high nip drum seals hole.It this method effective solution the problem of interlayer is broken in the prior art, is not influenced by pile diameter, so that it may complete the work of piling.

Description

Cast-in-situ bored pile breaks a processing method

Technical field

The present invention relates to anchor pole clearance technique fields more particularly to a kind of cast-in-situ bored pile to break a processing method.

Background technique

Currently, bored concrete pile usually carries out in the following way in production, first makes a hole on the ground, place into reinforcing bar Concrete is driven into steel reinforcement cage finally by Grouting Pipe, Grouting Pipe is usually first deep into the bottommost in hole, slowly by cage Mention upwards, for the concrete in Grouting Pipe from the bottom in hole as Grouting Pipe promotion is injected into hole, the mud in hole can quilt Concrete is upward out.But in practice of construction, if Grouting Pipe promotion is too fast, mud will be mixed between concrete, Or Grouting Pipe is broken in lifting process, can all mud be caused to enter between concrete, there have been the folders of concrete for this Layer, which is mud, leads to the weakened of entire bored concrete pile, and such case occurs in general unit in charge of construction, is all weight A stake is newly played, this cost is relatively high, and also a kind of mode is to make a hole on bored concrete pile after solidification, then be put into hole A piece reinforcing bar, reinjects concrete, to play the role of connecting two parts above and below interlayer, this mode to diameter compared with Small bored concrete pile is also possible that but bored concrete pile more than one meter in diameter is not appropriate for that must need very thick reinforcing bar, because And the program and unrealistic.

Summary of the invention

It is an object of the invention to overcome the shortcomings of above-mentioned technology, and provide a kind of cast-in-situ bored pile drawing broken pile treatment side Method.

To achieve the above object, using following technical scheme: a kind of cast-in-situ bored pile breaks a processing method to the present invention, It is characterized in that: the following steps are included:

Step 1: verifying the interlayer position of bored concrete pile；

Step 2: the depth in hole is up to the position of interlayer in one hole of centre drill of bored concrete pile；

Step 3: go deep into a Grouting Pipe into hole, be equipped with a sealing ring front ring week of the Grouting Pipe, sealing ring with The inner wall in the hole is fitted close, and Grouting Pipe is deep into interlayer, injects high pressure concrete into interlayer, and high pressure concrete is by mud Slurry is squeezed out from interlayer；

Step 4: being lifted up Grouting Pipe, while high pressure concrete is injected into hole, final high nip drum is solidifying native by Kong Mi Envelope.

Preferably, the diameter in the hole is 110mm-120mm.

Preferably, in step 1, using the position of ultrasonic equipment detection interlayer.

Preferably, the sealing ring is rubber material.

The beneficial effects of the present invention are: compared with the existing technology, interlayer is disconnected in the prior art for this method effective solution The problem of splitting, by making a hole on bored concrete pile, the diameter in the hole is very small, can be adapted for diameter at one meter or more The effect for acting on hole in the prior art of the work of bored concrete pile piling, hole is different, and the application mesoporous is as connection interlayer Channel, and one sealing ring, the side wall tight fit of the sealing ring and hole are set in the front of Grouting Pipe, such interlayer is exactly The space of one sealing, then high pressure concrete is injected into Grouting Pipe, high pressure concrete enters backward in interlayer from Grouting Pipe Surrounding squeezes mud, and the originally position of mud will be accounted for by high pressure concrete into mud is expressed into the sky of surrounding from interlayer Between, after high pressure concrete fills full interlayer, realize the pile extension of upper and lower ends bored concrete pile, finally as Grouting Pipe is lifted up, High pressure concrete fills hole.

Detailed description of the invention

Fig. 1 is that the structural schematic diagram of interlayer occurs in bored concrete pile in the present invention；

Fig. 2 is the structural schematic diagram for injecting high pressure concrete in the present invention into interlayer；

Fig. 3 is state diagram when Grouting Pipe is lifted up in the present invention.

Specific embodiment

With reference to the accompanying drawing and the preferred embodiment specific embodiment that the present invention will be described in detail.As shown in Figure 1-3, a kind of Cast-in-situ bored pile breaks a processing method, comprising the following steps:

Step 1: verifying 1 position of interlayer of bored concrete pile；Using the position of ultrasonic equipment detection interlayer.

Step 2: the depth in hole is up to the position of interlayer in one hole 2 of centre drill of bored concrete pile；In the straight of the hole Diameter is 110mm-120mm.The diameter of mesoporous of the present invention can be beaten very small, not limited by pile diameter, and cost is very It is low.

Step 3: going deep into a Grouting Pipe 3 into hole, the front ring week of the Grouting Pipe is equipped with a sealing ring 4, described close Seal ring is rubber material.Sealing ring and the inner wall in the hole are fitted close, and Grouting Pipe is deep into interlayer, are injected into interlayer high Concrete 5 is pressed, high pressure concrete squeezes out mud 6 from interlayer；Due to all loosening the soil around general bored concrete pile, so high pressure is mixed Mud can be easily extruded into the loosening the soil of surrounding by solidifying soil.

Step 4: being lifted up Grouting Pipe, while high pressure concrete is injected into hole, final high nip drum is solidifying native by Kong Mi Envelope.This method can be linked together the bored concrete pile of fracture with the concrete of same specification, and intensity was with being identical in the past 's.

By making a hole on bored concrete pile, the diameter in the hole is very small, can be adapted for diameter at one meter or more The effect for acting on hole in the prior art of the work of bored concrete pile piling, hole is different, and the application mesoporous is as connection interlayer Channel, and one sealing ring, the side wall tight fit of the sealing ring and hole are set in the front of Grouting Pipe, such interlayer is exactly The space of one sealing, then high pressure concrete is injected into Grouting Pipe, high pressure concrete enters backward in interlayer from Grouting Pipe Surrounding squeezes mud, and the originally position of mud will be accounted for by high pressure concrete into mud is expressed into the sky of surrounding from interlayer Between, after high pressure concrete fills full interlayer, realize the pile extension of upper and lower ends bored concrete pile, finally as Grouting Pipe is lifted up, High pressure concrete fills hole.

The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered It is considered as protection scope of the present invention.
