Abstract
The utility model belongs to bridge maintenance technical field of construction, it particularly relates to arrive a kind of loessial gulch area bridge lower part drainage system.Including gutter, concrete cushion, flexible porous tube, cobble loaded filter, coarse sand loaded filter and diversion pipe.Build gutter on concrete cushion by laying bricks or stones；On concrete cushion flexible porous tube is laid with along gutter；Cobble loaded filter is set on flexible porous tube；Diversion pipe is buried in the cobble loaded filter altitude range of gutter both sides；It is coarse sand loaded filter on cobble loaded filter；On coarse sand loaded filter loess is tamped for top layer.Compared with prior art, drainage system operation in bridge lower part described in the utility model is reliable, prevents bridge substructure from washing away damaged or destroyed by flood, and whole system construction is quick, and durability is good, ensures bridge substructure safety.
Description
Technical field
The utility model belongs to bridge maintenance technical field of construction, it particularly relates to arrive a kind of loessial gulch area bridge
Lower part drainage system.
Background technology
The Bridges in Mountainous Areas of standard span is used in Hinterland of Huangtu Plateau, due to the steep ditch depth in loessial gulch area slope, its underpart
Following characteristics are often presented in structure：Bridge pier is laid along side slope height, changes the equilibrium condition of original stability of slope, bridge pier platform
Side slope is the even high steep slope in high abrupt slope；Soil erosion or pile foundation ground avalanche nearby cause effective length insufficient；Operation phase bridge
Pile foundation soft rock-soil nearby is easily washed away in face central drainage.
Such as heavy showers, at the highway central drainage and bridge pier under directly the washing away of spilled water hole rainwater, the draining of bridge lower part
The ditch periphery soil body is easily peeled off, collapsed.Direct impact failure is caused to substructure, serious peace is brought to bridge substructure
Full hidden danger.
The content of the invention
In order to solve the above technical problems, the utility model provides a kind of loessial gulch area bridge lower part drainage system, can fit
For ensuring the normal operation and structure safety of bridge substructure.
Loessial gulch area bridge substructure drainage system described in the utility model, the drainage system include gutter
1st, basic unit 2, concrete cushion 3, flexible porous tube 4, cobble loaded filter 5, coarse sand loaded filter 6, surface layer loess 7, diversion pipe 8；Institute
State and be equipped with surface layer loess 7, coarse sand loaded filter 6, cobble loaded filter 5 and concrete outside the two side in gutter 1 successively from top to bottom
Bed course 3；The part intersection of the cobble loaded filter 5 and concrete cushion 3 is equipped with flexible porous tube 4 along the longitudinal direction of gutter 1；
The concrete cushion 3 also extends the underface in gutter 1, and on basic unit 2；1 two side of gutter is in ovum
Diversion pipe 8 is buried in 5 altitude range of stone loaded filter.
Loessial gulch area bridge substructure drainage system described in the utility model, the diversion pipe 8, which tilts, to be buried, low
End is located at 1 side of gutter.
When in use, can carry out in accordance with the following steps：1) compaction in layers basic unit loess；2) concrete is set on basic unit
Bed course；3) pulping line up the drain is started on concrete cushion；4) on concrete cushion flexible porous tube is longitudinally laid with along gutter；
5) cobble loaded filter is set on flexible porous tube, and in gutter both sides, the tilted embedded bilayer of cobble loaded filter altitude range is led
Flow tube；6) coarse sand loaded filter is laid with cobble loaded filter, the processing of coarse sand loaded filter is closely knit；7) top layer is covered on coarse sand loaded filter
Loess, surface layer loess compacting.
Compared with prior art, drainage system operation in bridge lower part described in the utility model is reliable, prevents bridge lower part
Structure washes away damaged or destroyed by flood, ensures bridge substructure safety, and whole system construction is quick, and late maintaining maintenance cost is low, economical
Rationally, durability is good.
