The utility model discloses a road cutting pile-plank trough type retaining wall structure for a railway rich water area. The road cutting pile-plank trough type retaining wall structure has good waterproof effect, high rigidity and small deformation. The road cutting pile-plank trough type retaining wall structure comprises pile foundations (21) and reinforced concrete U-shaped troughs, wherein the pile foundations (21) are arranged in rows along the road extending direction at intervals, a joist (22) is fixedly combined on the top end of each row of pile foundations (21), and each reinforced concrete U-shaped trough constituted by one base plate (11) and two side walls (12) is poured on each joist (22), and waterproof structures are arranged under the base plate (11) and at the outer sides of the side walls (12).
Description
Technical field
The utility model relates to retaining wall, particularly the board-like grooved retaining wall structure of the rich water route of a kind of railway moat area stake.
Background technology
Higher in rich groundwater, groundwater table, precipitation, draining or put the excavation location roadbed that sloping condition is restricted and the short embankment highway section roadbed that surface water is abundant, draining is difficult, traditional cutting retaining wall can't be protected railway operation safety.Domestic as Hunan and Guangxi line DK260+645～the DK260+771 section is positioned at the Quanzhou County, Guangxi, be in the groove location between the hills.Railway passes through with cutting, the excavation degree of depth 5～6m.Cover the Quaternary system Holocene series on the face of land towards proluvial mud matter clay, be taupe, the soft shape～stream of moulding is moulded shape, thick 8～9m, and a large amount of plant roots and stems that rot of folder, water content is big; Subterrane has Cretaceous strata mud stone folder argillaceous sandstone, limestone, dolomite folder shale.Mud stone presss from both sides argillaceous sandstone based on mud stone, mulberry, aubergine, and argillaceous texture, massive structure, rock matter is soft, the joint agensis, rock mass is complete, and partly mound hangwind inequality there are differences weathering, the weak dilatancy of tool.Limestone, dolomite folder shale are greyish white, Dark grey, in～the lamelliform distribution.Surface drainage is grown in the section, for ditch-water and paddy field water, mainly is subjected to the Atmospheric precipitation supply.Underground water is mainly Quaternary system hole phreatic aquifer, bedrock fracture water.At 27 meters, distance line midline right side one well is arranged, about 3 meters of well depths, for bedrock fracture water flows automatically with the rising water form, by right side massif subterrane crevice water supply, the water yield four seasons are stable, are local resident's main drinking water.
The utility model content
Technical problem to be solved in the utility model provides the board-like grooved retaining wall structure of the rich water of a kind of railway area cutting stake, and its waterproof effect is good, and rigidity is big, distortion is little.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
The board-like grooved retaining wall structure of the rich water of the utility model railway area cutting stake, it is characterized in that: it comprises pile foundation and the U-shaped groove of steel concrete, pile foundation sets in a row at interval along the route bearing of trend, the top of each campshed base is consolidated with joist, built more than joist by the U-shaped groove of steel concrete that base plate and both sides abutment wall constitute, below base plate, reach abutment wall arranged outside waterproof construction.
The beneficial effects of the utility model are, rigidity is big, distortion is little, good stability, receipts slope, a retaining, the good characteristics of waterproof effect, be applicable to that rich groundwater, groundwater table are higher, precipitation, draining or put the excavation location roadbed that sloping condition is restricted and the short embankment highway section roadbed that surface water is abundant, draining is difficult.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the profile of the board-like grooved retaining wall structure of the rich water of railway area cutting stake;
Fig. 2 is the schematic partial sectional view of the board-like grooved retaining wall structure of the rich water of railway area cutting stake
Component shown in the figure, toponym and corresponding mark: base plate 11, abutment wall 12, pile foundation 21, joist 22, waterproofing course 31, flexible protective layer 32, permanent brick wall 33, pea gravel concreten topping 34, concrete cushion 35.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, the board-like grooved retaining wall structure of the rich water of railway of the present utility model area cutting stake, it comprises pile foundation 21 and the U-shaped groove of steel concrete, pile foundation 21 sets in a row at interval along the route bearing of trend, the top of each campshed base 21 is consolidated with joist 22, built in joist more than 22 by the U-shaped groove of steel concrete that base plate 11 and both sides abutment wall 12 constitute, reach abutment wall 12 arranged outside waterproof constructions below 11 at base plate.
The U-shaped flute length phase of steel concrete sentences below the underground water, and whether anti-, Drainage Design effectively directly influences soundness and the durability of structure itself.With reference to Fig. 2, described waterproof construction comprises and is arranged on base plate below 11 and the waterproofing course 31 in abutment wall 12 outsides that waterproofing course 31 is that material is the cold adhesive waterproof coil of synthetic high polymer prespreading along the full section laying water-proof coiled material of the U-shaped groove upstream face of steel concrete.Between base plate 11 bottom surfaces and the waterproofing course 31 pea gravel concreten topping 34 is set, lays concrete cushion 35 between waterproofing course 31 and the joist 22, the both sides waterproofing course 31 outer flexible protective layers 32 that arrange, flexible protective layer 32 adopts polyethylene foams sheet material usually.The outside in base plate 11 and abutment wall 12 intersection arranges permanent brick wall 33 outside waterproof construction.
The U-shaped groove of described steel concrete adopts waterproof concrete to build and forms, and the impervious grade of waterproof concrete is P8.Waterproof concrete is answered continuous placing, should stay constuction joint less, and the junction of base plate and abutment wall should not stayed in horizontal shrinkage joint, should stay to exceed on the body of wall that floor surface is not less than 300mm.Vertical construction joints should or induce seam to be arranged on same section with deformation joint.The constuction joint place establishes the galvanized sheet waterstop and water-swellable sealing glue carries out waterproof, shrinkage joint place establishes back sticking type rubber fastening band and steel limit rubber fastening band and carries out waterproof and between constuction joint, shrinkage joint and chamfering place waterproofing course and the U-shaped groove structure of steel concrete the waterproof reinforced layer is set, and the waterproof reinforced layer material is the cold adhesive waterproof coil of macromolecule prespreading.
Some principles of the board-like grooved retaining wall structure of the above the utility model railway that just explains through diagrams rich water area cutting stake, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
