Description

A kind of compound pile for prestressed pipe

Technical field

Engineering construction field is the utility model is related to, specifically a kind of compound pile for prestressed pipe.

Background technology

In the existing Industrial and Civil Engineering pile foundation in China, largely prestressed concrete pipe pile or steel-pipe pile are used Pile foundation.This kind of pile for prestressed pipe has easily manufacture and assembly process and excellent mechanicalness as precast construction stake Can, it is mainly used in pile foundation engineering to improve ground and the bearing capacity on basis, particularly with being built in unstable soil layer or Soft Soil Layer On building and infrastructure projects, prestressed concrete pipe pile is by the way that the load of building to be transferred to the stable rock of underground On layer, so as to support building, it is ensured that its safety.

It is stronger that the constuction loads on top can be delivered to depths bearing capacity by the concrete tubular pile of existing structure in terms of stress Soil layer on or by the compacted reality of Soft Soil Layer to improve the bearing capacity of foundation soil and compactness.However, conventional prefabricated tubular pile is deposited In low intensity, resist and beat the shortcomings that ability is weak, although being equipped with strengthening intensity through bar construction in current pile tube, These are generally only the vertical or rule winding arrangement on cylinder through reinforcing bar, can not still solve the defects of its shear behavior, Be by lateral shearing force its structural strength enhancing it is extremely limited, be easy to contract in the case where side force is excessive Neck, cracking, the situation of broken pile, influence pile construction integrity and bearing capacity of single pile, it is therefore necessary to carry out supervision of construction, Guan Chang Record and quality testing, to ensure quality, hidden danger is reduced, and these have resulted in the increase of extra human cost.

Utility model content

The technical problem that the utility model solves is to provide a kind of compound pile for prestressed pipe, using meeting structure pair Pile tube side wall is strengthened, to solve the shortcomings that anti-shear ability is weak in pile for prestressed pipe in the prior art.

The technical problem that the utility model solves is realized using following technical scheme：

A kind of compound pile for prestressed pipe, including concrete pile body, the anchor ring interior edge pile body height of the concrete pile body Direction set more deformed bars, these deformed bar lateral surfaces wrapped by spiral hoop-iron it is spacing, meanwhile, described One layer of hexsteel is fixed with the outside of deformed bar and spiral hoop-iron, and is enclosed with one layer of nylon in the hexsteel outer surface and knits Nitride layer and one layer of carbon cloth, whole deformed bar, hexsteel, RIPSTOP layer, carbon cloth and spiral hoop-iron embedding One layer of steel structural layer is also set with the concrete pile body, and in the concrete-pile volume surrounding.

In the utility model, the concrete pile body both ends are closed by end plate.

In the utility model, the RIPSTOP layer and the carbon cloth take shape in concrete pile body and steel structural layer Interface on.

In the utility model, setting quantity of the deformed bar in the anchor ring of concrete pile body is 8 ~ 16.

In the utility model, the ratio between ring footpath of the concrete pile body and the steel structural layer is 4:1~6:1.

In the utility model, five pitch-rows of the hexsteel are 2cm, and thickness is 8 ~ 15mm.

In the utility model, concrete pile body is poured in pouring molding using pressurization, to ensure the hexsteel Concrete is filled up in gap.

Beneficial effect：The utility model technique is simple, and cost is low, cost-effective, by sandwich in concrete Carry out on the outside of pile body compound, the advantages of having had both concrete tubular pile and steel construction pile tube, meanwhile, pass through hexsteel, RIPSTOP Layer, the composite construction of carbon cloth are set, and it is poor effectively to compensate for existing pile tube anti-bending strength, are destroyed as brittle break, and ductility is poor, It is rapid after pile tube is cracking to spread, cause tensile region reinforcing bar to enter surrender quickly and tighten until the problem of being broken, improves The overall performance of pile tube.

Embodiment

In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.

Referring to a kind of preferred embodiment of Fig. 1 compound pile for prestressed pipe, in the present embodiment, pile for prestressed pipe it is interior Layer be concrete pile body 5,12 deformed bars 6 of the anchor ring interior edge pile body short transverse setting of the concrete pile body 5, this The lateral surfaces of deformed bar 6 are wrapped spacing by spiral hoop-iron 4 a bit, and are closed at the both ends of concrete pile body 5 by end plate, Deformed bar 6 is integrated at both ends with end plate soldering so that concrete pile body 5 keeps being relatively fixed with end plate.Concrete pile body 5th, deformed bar 6, spiral hoop-iron 4 and end plate form the structure of traditional concrete tubular pile.

In the present embodiment, although deformed bar 6 and spiral hoop-iron 4 are potted in concrete pile body 5, pre- The hexsteel 3 that one layer of five pitch-row is 2cm, thickness is 12mm is also fixed with the lateral surface of stress reinforcing bar 6 and spiral hoop-iron 4, One layer of RIPSTOP layer and one layer of carbon cloth book moulding complex textile layer 2, prestressing force are enclosed with the outer surface of hexsteel 3 Reinforcing bar 6, hexsteel 3, complex textile layer 2 and spiral hoop-iron 4 are potted in the concrete pile body 5, and in pouring molding Shi Caiyong pressurizations pour, to ensure to fill up concrete in the gap of hexsteel 3.

In addition, one layer of steel structural layer 1 is also set with the outside of complex textile layer 2, the steel structural layer 1 and concrete pile body The ratio between 5 ring footpath is 1:4.The steel structural layer 1 can make the performance of the certain steel construction pile tube of pile tube holding, while can also be to its side Face stress is protected, and prevents that it from cracking occurring when side receives impact or other stress destroy.

The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model Claimed scope is by appended claims and its equivalent thereof.
