Abstract
The utility model discloses a step type retaining wall used in transportation road engineering protection, which is characterized in that: reinforced concrete is used for making a rectangular parallelepiped and a cube which is not sealed at the top and is not packed at the bottom or other box block with geometric deformable body; steel plates are preinstalled at the joint between the box blocks and are arrayed staggeringly in sequence along the length direction of the protection engineering according to sequence from the lower to the upper and from the big to the small; fixing connection is adopted between the box blocks through filling sand gravels. The utility model has the advantages of small occupying area, material saving, good stability, high construction speed, novel structure and convenient connection.
Description
The utility model relates to a kind of staged retaining wall, belongs to the traffic highway field of engineering technology.
According to " subgrade construction) " (People's Transportation Press, the 1st edition the 2nd printing in December nineteen ninety, institution of higher education's teaching material of Fang Zuoying chief editor); " retaining wall commonly used at present mainly contains following four kinds of modes for road construction engineer handbook (Yang Wenyuan, Qian Shaowu compile for People's Transportation Press, the 1st edition the 1st printing December in 1997), data introduction.One, gravity retaining wall: rely on wall body deadweight support soil pressure to keep it and stablize,, be divided into road cutting type protecting wall, curb formula retaining wall, soaking type retaining wall, balance weight retaining wall etc. again according to landform, geology and applicable elements difference.Gravity retaining wall, the wall back of the body bear that soil pressure is bigger, and for the Stability Analysis of Structures security needs, its sectional dimension is bigger, and quantity of masonry is bigger, causes that investment strengthens, and is subjected to the foundation capability restriction in addition, and the retaining wall height often is restricted; Two, tied retaining wall: generally include anchor rod type and grappling is board-like, form by steel bar concrete metope anchor pole, form anchor, dependence is anchored at the horizontal pull of the anchor pole (or form anchor) in the rock stratum (or soil layer) and bears soil pressure, keeps full wall balance, belongs to lightweight structures, save material, ground is stressed little, and the basis is less demanding, but it must possess special mechanical equipments such as rig, mudjack, working procedure is many, the required precision height; Three, thin wall-type retaining wall: be reinforced concrete structure, comprise two kinds of forms of cantilever-type and counterfort formula, form that cross dimensions is less by upright arm, toe of wall plate, wall heel slab (counterfort), stability of structure is not the weight of dependence itself, and mainly rely on the weight of banketing on the heel slab to guarantee, and economize from heavy and light, bricklaying, be applicable to the situation that the wall height is bigger, but the moment of flexure of upright arm bottom is big, needing increases amount of reinforcement, takes material, uneconomical; Four, reinforced earth formula retaining wall: be by banket and in banketing, arrange connect rib, and shingle nail three parts are formed.In direction perpendicular to metope, at regular intervals and height, flatly place the lacing wire material, fill compaction then, by banket and lacing wire between rubbing action, native side pressure is passed to lacing wire, thereby stablizes the soil body.Reinforced earth formula retaining wall belongs to flexible structure, and big to foundation deformation compliance, building height is big, is applicable to fill subgrade.It is simple in structure, and quantity of masonry is few, and is good in economic efficiency.But facts have proved that through construction in recent years because of its working procedure is many, difficulty is big, banketing in the panel zone (1.5 meters) is difficult for compacting, and after building up, the long-term driving vehicle in road surface produces the loose drawstring of vibration, causes slippage, makes the roadbed drawing crack and destroys, and loses non-shallow.
The purpose of this utility model provides a kind of novel structure, is convenient to connect, and takes up an area of and lacks, and material is economized, good stability, the fast staged retaining wall of constructing.
The purpose of this utility model realizes as follows.
The operating principle of staged retaining wall: according to soil mechanics relevant main (quilt) the pressure basic theories of breaking ground, adopted the stability of triangular-section, with the principle design that keeps off stone with soil retaining soil, with stone, adopt thin-wall reinforced concrete to make peripheral material, do not seal item, the following case piece that does not wrap the end above making, the default steel plate in junction between the case piece, be shape on an empty stomach, (from big to small) is along the orderly arrangement straggly of preventive works length direction successively from down to up, affixed successively between the case piece, filling gravel forms, and forms the retaining wall like " staged ".
The cabinet design of staged retaining wall is cube, cuboid or other geometry deformation body.
The cross reinforcement is set in the middle of staged retaining wall lower tank piece.
The utlity model has following advantage.
1, novel structure is just opened connection.The staged retaining wall is convenient to be connected with acute angle, the obtuse angle of skew bridge (culvert), has solved reinforcement slab drawstring and has fought, installs insecure problem at sharp, obtuse angle part interleave.
2, occupation of land is few, economical with materials.The staged retaining wall adopts with soil retaining soil, stable road bed with the method for stone retaining stone, and occupation of land is few, can economical with materials.Than reinforced earth formula retaining wall saving investment 10-15%, force of gravity formula retaining wall saving investment 20-30%.
3, good stability.The staged retaining wall is born lateral pressure by gravity, has solved reinforced earth formula retaining wall and establish drawstring and the embankment problem of easily breaking near soil mass sliding surface, and therefore, it has greater advantages aspect stability and safety.
4, speed of application is fast.Each case piece of staged retaining wall can be prefabricated in advance, obviously effect of performance in accelerating construction progress, assault emergency work.
Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 7 is about the utility model, case piece seam in the left and right sides connects side view.
Fig. 8 is the utility model embodiment front view.
As shown in the figure, with the cuboid reinforcing cage that has the cross reinforcement in the middle of reinforcing bar (1.2) establishment, with reinforcing bar (3.4) establishment cuboid reinforcing cage, be prefabricated into respectively and do not seal item, do not wrap cuboid reinforcing steel bar concrete box piece A, B, C, the D at the end, the junction pre-embedded steel slab (7) between case piece A, B, C, D down.Along the preventive works length direction, puzzle the basis of retaining wall, earlier a plurality of case piece A are lifted on the basis successively, horizontal junction between the case piece A is gone up attached one at pre-embedded steel slab (7) and is connected steel plate (8) firm welding, and with filling gravel among the case piece A, it is closely knit to pour water; Lift on the case piece A a plurality of case piece B are straggly successively again, vertical (upper and lower) junction of case piece A, B, horizontal junction between the case piece B is gone up attached one at pre-embedded steel slab (7) and is connected steel plate (8), firm welding, with filling gravel among the case piece B, it is closely knit to pour water.According to said method, successively a plurality of case piece C, D are in place, promptly form like step-like retaining wall.
