Description

Combined type reinforced earth piling wall retaining structure
Technical field
The utility model relates to the railway bed building field, relates in particular to a kind of combined type reinforced earth piling wall retaining structure.
Background technology
Along with railway construction in China is extended to the mountain area, railway usually can be built on the ground of weak slope.Simultaneously, the requirement of, the gradient linear in order to satisfy and elevation also need be filled high embankment on the ground of weak slope.And, for the stability that prevents that foundation instability from sliding and the soil body is filled in maintenance, need to adopt retaining structure that weak slope ground and high embankment are supported.
At present, retaining structure commonly used has two kinds, and a kind of is gravity retaining wall, and it is used for the richer real area of building stones more.Yet the height that gravity retaining wall supports is limited, thereby it is of limited application.Another kind is a reinforced earth bulkhead, and it is used for lacking the regional of building stones more and it belongs to flexible structure, can bear the stability that the bigger distortion of ground also can improve the soil body.Yet reinforced earth bulkhead only plays supporting role preferably to high embankment, and is limited for the supporting role of weak slope ground, thereby, can not realize whole support to weak slope ground and high embankment.
Therefore, be necessary to provide a kind of combined type reinforced earth piling wall retaining structure to overcome above-mentioned defective.
The utility model content
The purpose of the utility model provides a kind of combined type reinforced earth piling wall retaining structure, can not only realize integrated support to weak slope ground and high embankment, and, widen the filled height of embankment, and improved the stability and the applicability of high embankment.
To achieve these goals; The utility model provides a kind of combined type reinforced earth piling wall retaining structure; Be used to support weak slope ground and high embankment, it comprises gravity barricade, cushion cap, be fixed on the foundation pile in the ground of weak slope and be positioned at the multistage reinforced earth bulkhead of gravity barricade top, and cushion cap is positioned on the foundation pile and foundation pile and cushion cap are integral structure; Gravity barricade and cushion cap CONTACT WITH FRICTION; Every grade of reinforced earth bulkhead comprises barricade panel, multilayer GSZ and a plurality of inclusion enclave, and the barricade panel is located at high embankment side and is connected with the soil body of high embankment through anchor pole, and a plurality of GSZs laterally are laid in the soil body of high embankment along high embankment from the bottom to top successively; Every layer of GSZ covered inclusion enclave near an end of barricade panel, and the terminal reflexed of GSZ wraps up inclusion enclave.
Preferably, every grade of reinforced earth bulkhead also comprises concrete pedestal, concrete cap stone and hardcore bed, and concrete pedestal and concrete cap stone are located at the two ends up and down of barricade panel respectively, and hardcore bed is located at the concrete pedestal below.
Preferably, the height of every grade of reinforced earth bulkhead is smaller or equal to 8 meters.
Preferably, the thickness of barricade panel is 0.2 meter, and the ratio of slope of barricade panel is 1: 0.05.
Preferably, the longitudinal pitch between per two anchor poles is 1 meter.
Preferably, the spacing of every layer of GSZ is 0.3 meter.
Preferably, inclusion enclave is the packed sand folder of braiding cobble.
Preferably, each cushion cap has two foundation stakes, is spaced apart 5 meters between per two foundation stakes.
Preferably, the ratio of slope of gravity barricade is 1: 0.25, and height is less than 10 meters.
Preferably, be equipped with a plurality of spilled water holes on gravity barricade and the barricade panel.
Compared with prior art; Pile foundation, cushion cap, gravity barricade and reinforced earth bulkhead in the combined type reinforced earth piling wall retaining structure of the utility model can support weak slope ground and high embankment respectively, thereby, can prevent that not only the slope ground from sliding along weak structural plane; And; Can widen embankment filled height, the stability that improves high embankment and applicability and reduce land used, thereby, guarantee the safety of railway operation and saved investment.
Through following description and combine accompanying drawing, it is more clear that the utility model will become, and these accompanying drawings are used to explain the embodiment of the utility model.
