Description
Technical field
The utility model relates to geotechnical engineering, in particular to a kind of expensive soil cutting deep layer discharge structure.
Background technique
Expensive soil cutting structure is influenced due to excavating, and WATER LEVEL CHANGES is larger, when high-speed railway especially non-fragment orbit
When high-speed railway is built in expensive soil cutting, how controlling groundwater level fluctuation to avoid expansive soil foundation in underground water
Position 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, expansive soil foundation SEA LEVEL VARIATION fluctuates width
Spend larger, depth reaches 5m 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 expensive soil cutting deep layer discharge structure, effectively to solve deep layer rock foundation
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 expensive soil cutting deep layer discharge structures, to realize depth
The water level of layer underground 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 expensive soil cutting deep layer discharge structure of the utility model, it is characterized in that it includes: vertical shaft, longitudinal gap is set
It sets in the expansive soil foundation on the outside of road structure；The swelled ground between adjacent vertical shaft is arranged in vertical drainage body, longitudinal gap
In ground；Longitudinal drainage body is horizontally arranged at interval in the expansive soil foundation of silo bottom；It is engaged rotary churning pile, is set to adjacent
In expansive soil foundation between vertical shaft, positioned at the outside of vertical drainage body and longitudinal drainage body；Oblique displacement hull is faced upward, is arranged in roadbed
In expansive soil foundation below structure, 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 expansive soil foundation in big depth bounds not is influenced by ground water-level fluctuation, avoids it and unfavorable arch deformation occurs；
Traditional longitudinal the region between the heart and the diaphragm ditch deep layer constructional difficulties are efficiently solved, the technical problems such as investment is huge, construction safety risk is high, with wide
The features such as application value.
Detailed description of the invention
This specification includes following three width attached drawing:
Fig. 1 is a kind of plan view of expensive soil cutting deep layer discharge structure of the utility model；
Fig. 2 is the sectional view of I-I line along Fig. 1；
Fig. 3 is the 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, occlusion rotary churning pile 6, 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 expensive soil cutting deep layer discharge structure of the utility model includes: vertical shaft 1, between longitudinal direction
Every in the expansive soil foundation being arranged on the outside of road structure；Vertical drainage body 3, longitudinal gap are arranged between adjacent vertical shaft 1
In expansive soil foundation；Longitudinal drainage body 4 is horizontally arranged at interval in the expansive soil foundation of 1 bottom of vertical shaft；It is engaged rotary churning pile 6, if
It is placed in the expansive soil foundation between adjacent vertical shaft 1, positioned at the outside of vertical drainage body 3 and longitudinal drainage body 4；Face upward oblique draining
Body 5, is arranged in the expansive soil foundation below road structure, faces 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.Underground water is blocked to be engaged rotary churning pile 6, avoids it to long-term infiltration on the inside of roadbed.Using vertical drainage body 3 as
The vertical drainage channel of underground water drains into underground water rapidly among longitudinal drainage body 4 by its effect, to make top ground
Soil avoids being influenced by underground water.Longitudinally connected channel using longitudinal drainage body 4 as underground water rapidly can arrange underground water
Out other than impacted cutting range, and the expansive soil foundation underground water being discharged within the scope of roadbed can be accelerated by facing upward oblique displacement hull 5 then.
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,
Permeable earth working material is filled in hole, the surrounding of earth working material is wrapped up or used the pvc pipe outsourcing of aperture using permeable geotextiles
Permeable geotextiles.The longitudinal drainage body 4 is arranged number of rows and hole count and is determined according to underground water flow rate calculation, longitudinal drainage body 4
Perforation connection is intersected in drilling with the drilling of vertical drainage body 3, and is connected with adjacent vertical shaft 1 with the drainage grade not less than 4%
It is logical.
The above is a kind of some principles of expensive soil cutting deep layer discharge structure of the utility model that explain through diagrams,
Shown in being not intended to for the utility model to be confined to and in the specific structure scope of application, therefore all it may be utilized
It is corresponding modification and equivalent, belong to the applied the scope of the patents of the utility model.
