Abstract
The utility model patent is that one kind can allow compressed steel pipe concrete excavation support, by large diameter steel pipe, minor-diameter steel-tube, coagulation local soil type into.Minor-diameter steel-tube is enclosed in large diameter steel pipe and is inscribed within big steel pipe inwall, and minor-diameter steel-tube outer wall and Large-diameter Steel inside pipe wall weld together.When outside is to press, appropriate deformation can occur for large diameter steel pipe so that external pressure is released, and support is not destroyed integrally, reach and allow the purpose of pressure.The device can effectively improve roadway support quality, it is to avoid pressed through because of outside it is big and caused by Support structure damage.
Description
First, technical field
The utility model, which is related to one kind, can allow compressed steel pipe concrete excavation support, and the device can effectively improve roadway support
Construction quality, prevent from pressing through because of outside it is big caused by prop integrally destroy, so as to greatly improve the safety of supporting
Property.Belong to colliery tunnel support technical field.
2nd, background technology
Coal mining enters after deep mining, is influenceed, will be faced with shallow mining completely not by deep complex stress
Same engineering rock mass mechanics problem.Changed from the linear problems of rock mechanics of superficial part to the non-linear problems of rock mechanics in deep, gone out
Substantial amounts of supporting problem is showed.High-ground stress, soft rock, ultimate soft rock, strong dynamic pressure influence, country rock soft broken, smashed to pieces etc. are asked
Topic will all influence roadway support quality.Common concrete support can not meet the supporting requirement of depth high stress roadway.
3rd, the content of the invention
The utility model, which is related to one kind, can allow compressed steel pipe concrete excavation support, and the device is made by the reasonable deformation of support
A part of stress is released but support is not destroyed integrally, maximize the support action for playing support, it is effective to improve
The construction of roadway support.
One kind can allow compressed steel pipe concrete excavation support, large diameter steel pipe, minor-diameter steel-tube, and coagulation local soil type is into its feature
It is：Minor-diameter steel-tube is enclosed in large diameter steel pipe and is inscribed within big steel pipe inwall, minor-diameter steel-tube outer wall and large diameter steel pipe
Wall welds together.
As an improvement, large diameter steel pipe（1）With minor-diameter steel-tube（2）Constituted by high tensile steel tube.
As an improvement, large diameter steel pipe（1）With certain anti-pressure ability.
As an improvement, minor-diameter steel-tube（2）Interior casting concrete, minor-diameter steel-tube（2）Outside to be hollow.
The beneficial effects of the invention are as follows：The design structure is simple, easy for installation, improves the efficiency of construction of roadway support；When
Surrouding rock deformation is smaller, support by external pressure it is smaller when, large diameter steel pipe can play a part of resist surrouding rock deformation；With enclosing
Rock deformation is increased, and the pressure that support is subject to is with increase, and deformation takes place in large diameter steel pipe, and pressure from surrounding rock is released；Enclose
When rock deformation further increases, the concrete in minor-diameter steel-tube and steel pipe will provide powerful resistance, prevent country rock from entering one
Step deformation.
4th, illustrate
Fig. 1 one kind can allow compressed steel pipe concrete excavation support design drawing
Fig. 2 can allow compressed steel pipe concrete excavation support sectional view
Reference：（1）Large diameter steel pipe；（2）Minor-diameter steel-tube；（3）Concrete；
5th, embodiment
Embodiment of the present utility model is described in further detail with reference to the accompanying drawings and examples.Following reality
Example is used for illustrating the utility model, but is not limited to scope of the present utility model.
As shown in figure 1, the utility model, which is one kind, can allow compressed steel pipe concrete excavation support, including large diameter steel pipe 1, it is small
Diameter steel pipe 2, concrete 3.
Minor-diameter steel-tube is enclosed in large diameter steel pipe and is inscribed within big steel pipe inwall, minor-diameter steel-tube outer wall and Large-diameter Steel
Inside pipe wall welds together.When surrouding rock deformation is smaller, support by external pressure it is smaller when, large diameter steel pipe can play resistance and enclose
The effect of rock deformation；As surrouding rock deformation is increased, the pressure that support is subject to is with increase, and deformation takes place in large diameter steel pipe,
Pressure from surrounding rock is released；When surrouding rock deformation further increases, the concrete in minor-diameter steel-tube and steel pipe will provide powerful
Resistance, prevents country rock from further deforming the supporting effect for playing " first allow and resist afterwards ".
As an improvement, large diameter steel pipe（1）With minor-diameter steel-tube（2）Constituted by high tensile steel tube.
As an improvement, large diameter steel pipe（1）With certain anti-pressure ability.
As an improvement, minor-diameter steel-tube（2）Interior casting concrete, minor-diameter steel-tube（2）Outside to be hollow.
