Abstract
The utility model discloses a kind of pipe curtain freezing process supporting and protection structure, include several pipe curtain steel pipe and Frozen Soil Cylinder, wherein Frozen Soil Cylinder is located between adjacent pipe curtain steel pipe.Pipe curtain steel pipe be hollow or concrete interval is built or concrete is built entirely.The diameter of pipe curtain steel pipe is 0.3m-2m.The beneficial effects of the utility model: the utility model is combined pipe curtain steel pipe supporting and protection structure and Frozen Soil Cylinder supporting and protection structure, form large rigidity watertightness pipe curtain freezing process supporting and protection structure, effectively can control the loss of underground water, ensure construction and operation security, under being particularly suitable as the shallow large-section underground structure of saturated rich water soft soil layer, wear supporting and protection structure during Sensitive Buildings construction.
Description
Technical field
The utility model relates to a kind of supporting and protection structure, particularly a kind of pipe curtain freezing process supporting and protection structure.
Background technology
In recent years, along with the acceleration of Urbanization Process In China, under downtown roads or important building, build Large Underground Structure get more and more.For shallow embedding big cross section, short-range city tunnel, adopt shield construction uneconomical, adopt cut and cover method larger to the interference of city productive life.When geological conditions is poor, buried depth is more shallow, top is when having a Sensitive Buildings, if adopt shallow burial hidden digging construction, surface settlement is difficult to control, once there is construction accident, will cause significant social influence.Therefore, how to find a kind of be suitable for the shallow large-section underground structure of saturated rich water soft soil layer under to wear the construction supporting structure of Sensitive Buildings extremely important.
Summary of the invention
The purpose of this utility model is through not improving the problem of supporting and protection structure and a kind of pipe curtain freezing process supporting and protection structure of providing during saturated rich water soft soil layer in the work progress in order to solve existing shallow large-section underground structure.
A kind of pipe curtain freezing process supporting and protection structure that the utility model provides includes several pipe curtain steel pipe and Frozen Soil Cylinder, and wherein Frozen Soil Cylinder is located between adjacent pipe curtain steel pipe.
Pipe curtain steel pipe be hollow or concrete interval is built or concrete is built entirely.
The diameter of pipe curtain steel pipe is 0.3m-2m.
The pipe curtain freezing process support construction step that the utility model provides is as follows:
1, upper pipe working well and received well is constructed;
2, steel pipe jacking, jacking order for axis, cross section for benchmark from lower to upper symmetry carry out; Steel pipe laying method has: fixed (leading), to Drilling Method, horizontal spiral drilling method, rammer pipe construction method, pipe jacking method, miniature pipe jacking method/micro-tunneling construction method, the most frequently used is pipe jacking method.
3, freezing pipe construction between steel pipe, the number of freezing pipe is determined by the steel pipe spacing designed.
4, slip casting or injection concrete in steel pipe.
5, actively freeze to form Frozen Soil Cylinder.
6, excavate in pipe curtain freezing process supporting and protection structure, excavation limit, limit supports.
7, construct internal construction piecemeal, and progressively remove pipe curtain freezing process supporting and protection structure inner support, the underground structure that final formation is complete.
The beneficial effects of the utility model:
The utility model is combined pipe curtain steel pipe supporting and protection structure and Frozen Soil Cylinder supporting and protection structure, form large rigidity watertightness pipe curtain freezing process supporting and protection structure, effectively can control the loss of underground water, ensure construction and operation security, under being particularly suitable as the shallow large-section underground structure of saturated rich water soft soil layer, wear supporting and protection structure during Sensitive Buildings construction.
