Abstract
A kind of swelling rock cutting deep layer discharge structure excludes function with quick to realize that the water level of deep phreatic water is reduced, while difficulty of construction and construction investment is effectively reduced.It include: vertical shaft, longitudinal gap is arranged in the rock foundation on the outside of road structure；Vertical drainage body, longitudinal gap are arranged in the rock foundation between adjacent vertical shaft；Longitudinal drainage body is horizontally arranged at interval in the rock foundation of silo bottom；Oblique displacement hull is faced upward, is arranged in the rock foundation below road structure, is faced upward downwards tiltedly to silo bottom.
Description
Technical field
The utility model relates to geotechnical engineering, in particular to a kind of swelling rock cutting deep layer discharge structure.
Background technique
Swelling rock chasm structuref is influenced due to excavating, and WATER LEVEL CHANGES is larger, when high-speed railway is especially without tiny fragments of stone, coal, etc. rail
When road high-speed railway is built in swelling rock cutting, how controlling groundwater level fluctuation exists to avoid swelling rock ground
Level of ground water 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.Therefore it is badly in need of a kind of swelling rock cutting deep layer discharge structure, with effectively solving deep layer rock
Base precipitation, drainage problem, and have the characteristics that easy for construction, good economy performance, environmental protection and application value.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of swelling rock cutting deep layer discharge structures, to realize
The water level of deep phreatic water reduces and quickly excludes function, while difficulty of construction and construction investment is effectively reduced.
It is as follows that the utility model solves technical solution used by above-mentioned technical problem:
A kind of swelling rock cutting deep layer discharge structure of the utility model, it is characterized in that it includes: vertical shaft, longitudinal gap
It is arranged in the rock foundation on the outside of road structure；Vertical drainage body, longitudinal gap is with being arranged in the rock between adjacent vertical shaft
In base；Longitudinal drainage body is horizontally arranged at interval in the rock foundation of silo bottom；Oblique displacement hull is faced upward, is arranged in road structure
In the rock foundation of lower section, face upward downwards tiltedly to silo bottom.
The utility model has the beneficial effects that the water level that deep phreatic water may be implemented reduces and quickly excludes function, from
And guarantee the swelling rock ground in big depth bounds not is influenced by ground water level, avoids it and unfavorable arch deformation occurs；Have
The technical problems such as effect solves traditional longitudinal the region between the heart and the diaphragm ditch deep layer constructional difficulties, investment is huge, construction safety risk is high, have wide push away
The features such as wide application value.
Detailed description of the invention
This specification includes following three width attached drawing:
Fig. 1 is a kind of floor map of swelling rock cutting deep layer discharge structure of the utility model；
Fig. 2 is the cross-sectional view of I-I line along Fig. 1；
Fig. 3 is the cross-sectional view of II-II line along Fig. 1.
Component name and corresponding label are shown in figure: vertical shaft 1 checks ladder step 2, vertical drainage body 3, longitudinal drainage body
4, oblique displacement hull 5, roadbed bottom A, roadbed surface layer B, draining lateral sulcus C are faced upward.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples:
Referring to figs. 1 to Fig. 3, a kind of swelling rock cutting deep layer discharge structure of the utility model includes: vertical shaft 1, longitudinal
It is arranged at intervals in the rock foundation on the outside of road structure；Vertical drainage body 3, longitudinal gap are arranged between adjacent vertical shaft 1
In rock foundation；Longitudinal drainage body 4 is horizontally arranged at interval in the rock foundation of 1 bottom of vertical shaft；Oblique displacement hull 5 is faced upward, setting exists
In rock foundation below road structure, face upward downwards tiltedly to 1 bottom of vertical shaft.
Referring to Fig. 2, vertical shaft 1 is transported as construction longitudinal drainage body 4 and the construction channel for facing upward oblique displacement hull 5, and as the later period
The inspection shaft of battalion.Vertical drainage channel using vertical drainage body 3 as underground water drains into underground water rapidly by its effect vertical
To among displacement hull 4, so that Rock avoids being influenced by underground water with making top.Using longitudinal drainage body 4 as underground water
Longitudinally connected channel rapidly can be discharged underground water other than impacted cutting range, and facing upward oblique displacement hull 5 can then accelerate to arrange
Rock foundation underground water within the scope of roadbed out.
Referring to Figures 1 and 2, the vertical shaft 1 uses manually digging hole, and 1 surrounding of vertical shaft is that armored concrete goes along with sb. to guard him ruggedized construction,
Fixed setting checks the pedestrian passage that ladder step 2 is checked as the later period on its side wall.
Referring to Fig.1, the vertical drainage body 3 usually 2 rows of setting, interlaced arrangement.
Referring to figs. 1 to Fig. 3, the vertical drainage body 3, longitudinal drainage body 4 face upward oblique displacement hull 5 using geotechnical boring, in hole
The interior permeable earth working material of filling, the surrounding of earth working material are wrapped up using permeable geotextiles or use the pvc pipe outsourcing of aperture saturating
Water geotextiles.The longitudinal drainage body 4 is arranged number of rows and hole count and is determined according to underground water flow rate calculation, the brill of longitudinal drainage body 4
Connection is intersected in hole with the drilling of vertical drainage body 3, and is connected to adjacent vertical shaft 1 with the drainage grade not less than 4%.
The above is a kind of some originals of swelling rock cutting deep layer discharge structure of the utility model that explain through diagrams
Reason is not intended to shown in being confined to the utility model and in the specific structure scope of application, therefore all possible quilts
The corresponding modification utilized and equivalent, belong to the applied the scope of the patents of the utility model.
