Description
Technical field
The present invention relates to being related to geotechnical engineering, in particular to a kind of construction party of swelling rock cutting deep layer discharge structure
Method.
Background technique
Swelling rock chasm structuref is influenced due to excavating, and WATER LEVEL CHANGES is larger, when high-speed railway is especially without the tiny fragments of stone, coal, etc.
When rail high speed building railway is in swelling rock cutting, how controlling groundwater level to avoid swelling rock ground in underground
Water level effect is lower to occur upward expansion arch deformation, and being must technical problems to be solved.
Currently, the biggish longitudinal the region between the heart and the diaphragm ditch of depth usually is arranged in roadbed two in engineering practice, kept away by lowering of watertable
Exempt from or mitigate on the influence of the disadvantageous deformation of top high-speed railway, but in terms of actual effect, the fluctuation of swelling rock ground SEA LEVEL VARIATION
Amplitude is big, and depth reaches 10m or more sometimes, and longitudinal the region between the heart and the diaphragm ditch setting traditional in this way is limited or constructs extremely difficult, invests huge
Greatly, and construction safety risk is high.
To overcome the shortcomings of above-mentioned existing deep layer discharge structure, the applicant is in the utility model patent Shen proposed on the same day
It please disclose a kind of swelling rock cutting deep layer discharge structure, comprising: well body structure, longitudinal gap are arranged outside road structure
In the rock foundation of side；Vertical drainage body, longitudinal gap are arranged in the rock foundation between adjacent well body structure；Longitudinal row
Water body is horizontally arranged at interval in the rock foundation of well body structural base；Oblique displacement hull is faced upward, is arranged in below road structure
In rock foundation, face upward downwards tiltedly to well body structural base.The water level that deep phreatic water may be implemented in the structure is reduced and is quickly arranged
Except function, to guarantee that the swelling rock ground in big depth bounds is not influenced by ground water level, avoid its occur it is unfavorable upper
Arch deformation；Efficiently solve traditional longitudinal the region between the heart and the diaphragm ditch deep layer constructional difficulties, the technical problems such as investment is huge, construction safety risk is high.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of construction parties of swelling rock cutting deep layer discharge structure
Method so that deep layer discharge structure can effectively play its precipitation, drainage effect, ensure construction safety, improve construction efficiency, and is answered
With popularization and application foreground and meet environmentally friendly requirement.
It is as follows that the present invention solves technical solution used by above-mentioned technical problem:
Technical problem to be solved by the invention is to provide a kind of construction parties of swelling rock cutting deep layer discharge structure
Method, this method comprises the following steps:
1. carrying out floor marking in face of the position of setting well body structure and vertical drainage body on ground；
2. being arranged on the outside of vertical drainage body in cutting two sides and carrying out closing bored grouting construction；
3. stage excavation well body structure and and layered setting building enclosure；
4. the building enclosure higher slice inspection of construction ladder in well body structure walks；
5. repeat step 3., 4. until well body structural base, using concrete enclosing well body structural base；
6. it drills in ground construction vertical drainage body, the permeable geotechnological material that setting is wrapped up using permeable geotextiles in hole
Material；
7. in the construction longitudinal drainage body drilling of well body structural base, the drilling of longitudinal drainage body and the brill of vertical drainage body
Hole intersection perforation connection, and be connected to adjacent well body structure with the drainage grade not less than 4%, setting is using saturating in hole
The permeable earth working material of water and soil work cloth package；
8. facing upward oblique displacement hull drilling in the construction of well body structural base, drilling sets up the drainage grade not less than 4%,
The permeable earth working material that setting is wrapped up using permeable geotextiles in hole.
The invention has the advantages that can avoid or big by being closed in the outside of vertical drainage body using bored grouting
Width reduces later period two sides underground water to infiltration on the inside of cutting；First construction vertical drainage body, rear construction longitudinal drainage body, Ji Nengbao
Connection perforation is intersected in the drilling of card longitudinal drainage body with the drilling of vertical drainage body, it is thus also avoided that construction vertical drainage body drilling
Slag body enters in longitudinal drainage body；The construction method be effectively ensured construction safety, the validity of construction drainage, construction
High efficiency has popularization and application foreground, and meets the requirement of environmental protection.
Detailed description of the invention
This specification includes following three width attached drawing:
