Abstract

The utility model relates to a building construction structures discloses a novel civil engineering hollow pile, including pile body (1), round platform form protruding (2), pile body (3), round hole (4), outer wall (5), inner wall (6), pile body (1) comprises round platform form protruding (2) and pile body (3), pile body (3) comprise outer wall (5) and inner wall (6), and contain above pile body (3) a plurality of round hole (4), round platform form protruding (2) is connected with pile body (3) is whole. The utility model discloses a setting of round platform form protruding (2) and pile body (3) has increased pile body (1) area of contact with the soil body, has strengthened a stake side friction resistance, and the bearing capacity that makes the stake improves to be accelerated the drainage simultaneously and concrete speed, effectively reduces lateral pressure, can reduce the hollow pile and by the emergence of the too big accidents such as broken pile that cause of lateral pressure, reduce the production of building rubbish, environmental protection, saving social resources.

Description

A kind of novel hollow pile of civil engineering works

Technical field

The utility model relates to building operations structure, particularly relates to a kind of novel hollow pile of civil engineering works.

Background technology

In the middle of China's engineering construction, the circular pile tube of prestressing force and hollow square pile are widely used in the underpin such as house, bridge, harbour, harbour, at present, pile for prestressed pipe generally adopts cylindrical, it is made up of the concrete of circular reinforcing cage and parcel reinforcing cage, the profile of this pile for prestressed pipe is generally linear pattern, and this pile tube exists the shortcoming little with soil body frictional force; Along with further developing of stake technology, pre-stress hollow square pile more and more accept by masses, pre-stress hollow square pile has the advantage that pile body outer perimeter and stake second moment of area are all large than cylindrical pile tube when identical concrete amount, it can thus be appreciated that, when identical concrete amount, large than cylindrical pile tube of the bearing capacity of pre-stress hollow square pile pile body, however, the frictional force of pre-stress hollow square pile and the soil body is little or can not meet the requirement of practical application.

In addition, the outer wall smoother of conventional hollow stake, under acting by external hydrostatic pressure, the pore water oozed out in pile body surrounding soil easily forms " moisture film " at stake soil critical surface, to stake outer wall, there is certain lubrication, make pile body and surrounding soil can not form enough effective stake side skin friction, the bearing capacity of pile which results in more existing hollow piles does not reach the phenomenon required by design, is a problem demanding prompt solution for frictional property stake.

Therefore, for above problem, the utility model is transformed on the basis of original hollow pile again, in consolidated subsoil processing procedure, not only pile body itself can more effectively play a role, and strengthens pile side friction, and give full play to soil body nature, set up discharge conduit, make soil body generation discharging consolidation, thus reach the object strengthening whole pending foundation strength.In addition, this novel hollow pile of civil engineering works also has environmental protection, the features such as low-material-consumption.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming that prior art hollow core row of piles outlet capacity is not enough and bearing capacity of pile is not high, the bending resistance provide a kind of and obviously can increase frictional force between pile body and the soil body, improving stake and contribute to the novel hollow pile of civil engineering works of raising soil body discharging consolidation speed.

To achieve these goals, the scheme adopted is: a kind of novel hollow pile of civil engineering works, comprise pile body (1), round table-like projection (2), pile body (3), circular hole (4), outer wall (5), inwall (6), described pile body (1) is made up of round table-like projection (2) and pile body (3), described pile body (3) is made up of outer wall (5) and inwall (6), and described pile body (3) is above containing several circular holes (4), described round table-like projection (2) and pile body (3) integrated connection.

As preferably, between described circular hole (4), distance of center circle is 50mm ~ 100mm, and circular hole (4) diameter is 70mm ~ 150mm.

As preferably, described pile body (1) is made up of steel concrete.

Relative to prior art, the beneficial effects of the utility model are:

(1) the novel hollow pile of civil engineering works of one of the present utility model; by the setting of the pile body (3) of band circular hole (4); the pore water in the soil body is made to be drained in hollow pile; increase drainage path, accelerate discharging consolidation speed, effectively reduce lateral pressure; the generation of hollow pile by accidents such as excessive the caused broken piles of lateral pressure can be reduced; reduce the generation of building waste, protection of the environment, save social resources.

(2) the novel hollow pile of civil engineering works of one of the present utility model, by the setting of round table-like projection (2) and pile body (3), make pile body (1) external surface no longer smooth, increase the contact area of pile body (1) and the soil body, enhance pile side friction, make the bearing power increase of stake.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of novel hollow pile of civil engineering works, comprise pile body (1), round table-like projection (2), pile body (3), circular hole (4), outer wall (5), inwall (6), described pile body (1) is made up of round table-like projection (2) and pile body (3), described pile body (3) is made up of outer wall (5) and inwall (6), and described pile body (3) is above containing several circular holes (4), described round table-like projection (2) and pile body (3) integrated connection.

In the present embodiment, the novel hollow pile of civil engineering works of one of design, pile body (1) gos deep in the soil body, and round table-like projection (2) adds the contact area with the soil body, pile side friction is improved, thus strengthens self bearing capacity of hollow pile.

In the present embodiment; the novel hollow pile of civil engineering works of one of design; the surface of pile body (3) arranges several circular holes (4), makes the pore water in the soil body be drained in hollow pile, increases drainage path; accelerate discharging consolidation speed; effectively reduce lateral pressure, the generation of hollow pile by accidents such as excessive the caused broken piles of lateral pressure can be reduced, reduce the generation of building waste; protection of the environment, saves social resources.
