Abstract
The utility model provides a kind of cast-in-place pile concrete loss device that prevents, comprise cylinder bag, cylinder bag upper end support ring, cylinder bag lower end support ring, suspension arrangement is fixed on the support ring of cylinder bag upper end, described cylinder bag upper end support ring and cylinder bag lower end support ring are made by reinforcing bar, described suspension arrangement is made by galvanized wire, described suspension arrangement is fixed on ground, and the length of described cylinder bag surpasses the upper and lower 50cm of macadam thickness.Of the present utility model prevent cast-in-place pile concrete loss device be adopt there is certain permeability, the geosynthetics of good ductility and sufficient intensity, be prepared into the cylinder bag with castinplace pile equal diameter, after pore-forming, place it within the scope of the macadam that hole is larger, during concreting, this device can play buffer action, can effectively stop the concrete with mobility to be scurried in the macrovoid of macadam, because cylinder bag material has good ductility and sufficient intensity, can solve well concrete loss problem.
Description
Technical field
The utility model relates to the realm of building construction, specifically a kind of cast-in-place pile concrete loss device that prevents.
Background technology
Castinplace pile is a kind of deep foundation being widely used in civil engineering, can pass through the method such as boring, immersed tube pore-forming, manually digging hole and form a stake hole, places reinforcing cage, concreting forms in stake hole.The deviation occurring due to pore-forming makes a bore dia be greater than design size, and owing to may occurring the reasons such as hole wall Rock And Soil hole and collapse hole in work progress, causes the actual amount of pouring into of concrete to be greater than theoretical amount of calculation, and the ratio of the two is so-called fullness coefficient.Different hole forming methods, different soil, the fullness coefficient of castinplace pile is different, but is all not more than 1.2.In Practical Project, while running into macadam, because complex structure, pore diameter are large, concrete can be scurried in the macrovoid of macadam, causes concrete to run off, and occurs that fullness coefficient is much larger than 1.2, even reach the situation of 2-3, Zhe Shi designing unit can not consider, unit in charge of construction can't afford.
Summary of the invention
In order to solve the above-mentioned technical problem existing in prior art, the utility model provides a kind of cast-in-place pile concrete loss device that prevents, comprise cylinder bag, cylinder bag upper end support ring, cylinder bag lower end support ring, suspension arrangement is fixed on the support ring of cylinder bag upper end, described cylinder bag upper end support ring and cylinder bag lower end support ring are made by reinforcing bar, described suspension arrangement is made by galvanized wire, and described suspension arrangement is fixed on ground, and the length of described cylinder bag surpasses the upper and lower 50cm of macadam thickness.
Further, for macadam, be positioned at castinplace pile bottom and stake end when following, cylinder bag bottom arranges a cylinder bag bottom surface.
Of the present utility modelly prevent that cast-in-place pile concrete loss device from being to adopt to have certain permeability, the geosynthetics of good ductility and sufficient intensity, be prepared into the cylinder bag with castinplace pile equal diameter, after pore-forming, place it within the scope of the macadam that hole is larger, during concreting, this device can play buffer action, can effectively stop the concrete with mobility to be scurried in the macrovoid of macadam, because cylinder bag material has good ductility and sufficient intensity, so, the stake bore dia occurring because of pore-forming deviation is greater than design size, and due to the hole wall Rock And Soil hole and the collapse hole that occur in work progress, also can under concrete lateral pressure effect, well be filled, pile body and pile soil horizon close contact, guaranteed that pile peripheral friction force can not reduce, can solve well concrete loss problem.
Accompanying drawing explanation
Fig. 1 is the structural representation that prevents cast-in-place pile concrete loss device of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the cast-in-place pile concrete loss device that prevents of the present utility model, comprise cylinder bag 1, cylinder bag upper end support ring 2, cylinder bag lower end support ring 3, cylinder bag upper end support ring 2 and cylinder bag lower end support ring 3 are made by reinforcing bar, suspension arrangement 4 is fixed on the support ring of cylinder bag upper end, and suspension arrangement 4 is made by galvanized wire.For macadam, be positioned at castinplace pile bottom and stake end when following, cylinder bag bottom arranges a cylinder bag bottom surface 5.Suspension arrangement 4 is fixed on ground, and the length of cylinder bag 1 is controlled at over macadam thickness and is respectively not less than up and down 50cm.
Using method: after pouring pile hole, directly will prevent that cast-in-place pile concrete loss device from hanging on the macadam scope that hole is larger, ground is fixed on by suspension arrangement in upper end.The length of cylinder bag is controlled at over macadam thickness and is respectively not less than up and down 50cm.When bottom macadam is positioned at castinplace pile and when stake end is following, use the cylinder bag that adds bottom surface.Other construction technologies are constant.
Claims (2)
1. one kind prevents cast-in-place pile concrete loss device, comprise cylinder bag (1), cylinder bag upper end support ring (2), cylinder bag lower end support ring (3), it is characterized in that: suspension arrangement (4) is fixed on cylinder bag upper end support ring (2), described cylinder bag upper end support ring (2) and cylinder bag lower end support ring (3) are made by reinforcing bar, described suspension arrangement (4) is made by galvanized wire, described suspension arrangement (4) is fixed on ground, and the length of described cylinder bag (1) surpasses the upper and lower 50cm of macadam thickness.
2. the cast-in-place pile concrete loss device that prevents as claimed in claim 1, is characterized in that: for macadam, be positioned at castinplace pile bottom and stake end when following, cylinder bag bottom arranges a cylinder bag bottom surface (5).
