Description

Three-dimensional continuous frame formula reinforced concrete structure retaining wall
Technical field
The utility model belongs to construction project field, relates to a kind of retaining wall, specifically a kind of three-dimensional continuous frame formula reinforced concrete structure retaining wall that is applicable to the slope soils such as building, highway, railway both sides or a side, plays a gear effect.
Background technology
In construction project, for a retaining wall for gear slope soil, be widely used in different level region or be used for processing the local discrepancy in elevation, as the both sides such as highway, railway or a side slope soil.Retaining wall has gravity, half gravity, anchor rod type, cantilevered and holds up the forms such as arm-type, form anchor, reinforced earth, sheet pile formula, is so limited by traditional thoughtcast and economic factor, and retaining wall is always comparatively conventional with gravity, comparatively common to grout rubble.
It is simple that gravity retaining wall has form of structure, easy construction, the features such as strong adaptability, it is to utilize the rubble building block of surface imperfection to adopt cement mortar bonding to build by laying bricks or stones to form, lower and the easy dehydration of the intensity of masonry mortar own loses viscosity only as stablizing pad, moreover rubble stone retaining wall cross section is large, bricklaying quantity is larger, body of wall is from great, self structure intensity is lower, blockhouse load-bearing is supported and mostly is point-like (regular strip building block is planar contact), make body of wall part because pressure is excessive and broken or loosening, unstability causes body of wall to cave in, therefore gravity retaining wall is built and is often subject to bearing capacity and builds the high restriction of heap by laying bricks or stones to be difficult to meet actual demands of engineering on soft foundation.
Gravity retaining wall is easily by corollary failure and the extremely unstable hidden danger of bringing to engineering safety is more.Common damage form has the not enough distortion producing of foundation bed slip unstability, overturning, bearing capacity of foundation soil or because body of wall self intensity is lower from weak link sheared destruction.The loosening cracking that freeze thawing, immersion, mortar bonding composition inefficacy efflorescence cause etc. causes cannot continuing to bear lateral pressure and collapsing of occurring destroyed comparatively common.Because load changes as having heavy vehicle to pass through near plane wall top or additional other loads, top add make enclosure wall or near have super large vibration (blast working) to cause increasing load with former design load, intensity are not inconsistent, and cannot keep out by natural destruction body of wall and the destruction of the displacement that occurs or the form such as burst apart also happens occasionally.
The defect occurring for existing retaining wall form, architectural engineering technology personnel propose framed revetment scheme, as patent 201110235978 discloses a kind of open-type reinforced concrete frame retaining wall, by retaining wall, the triangle oblique pull wall (attached wall wall) being connected as a single entity with retaining wall forms, the continuous T word structure forming, although utilizing pilaster to carry out grappling, it strengthens stability, to increase the steadiness of retaining wall, and saving material, reduce costs, but retain existing counterfort retaining wall and Retaining Wall form, moreover lacked base plate, the pressure that attached wall wall produces ground increases easily makes structural instability, can not effectively resist the produced lateral pressure of banketing, fundamentally do not change retaining wall compressive resistance ability, be not suitable for slightly high Retaining Wall Engineering, can only be applicable to safeguard the stable of shorter side slope.
Also have researcher to design a kind of Novel retaining wall, by riser and system framework, the montant of framework is the bearing (fixing hinge) of riser, cross bar can connect into integral body by the riser of dual-side, the soil pressure that the formed both sides equal and opposite in direction of the earth filled out in framework, opposite direction are buried in utilization keeps retaining wall stable, and (horse is established an army etc., 1997), a kind of block form retaining wall in fact, the scope of application is less, be mainly used in channel both sides, irrigated area and keep off soil simultaneously, can not meet in the building construction processes such as road construction now and safeguard the needs that slope soil is stable.
Utility model content
The purpose of this utility model is to provide a kind of three-dimensional continuous frame formula reinforced concrete structure retaining wall for the deficiencies in the prior art, adopt tower structure, frame body is rooted in to stable soil supporting layer, make the lateral pressure of side slope soil layer dispersed by beam and column, avoid body of wall local pressure excessive, stable and the durability that guarantees retaining wall, can greatly reduce engineering safety hidden danger.
The technical scheme that the utility model adopts:
A kind of three-dimensional continuous frame formula reinforced concrete structure retaining wall, comprise stake, between stake and stake, by grade beam, connect firmly, above grade beam, connect firmly by steel concrete and build the post forming, between post and post, by the beam formation framework that is rigidly connected, at the outer facade of framework, shingle nail is set.Pass through drill-pouring, immersed tube bored, the routine building construction methods such as manually digging hole perfusion arrange reinforced concrete pile on the ground of retaining wall, the method of utilizing steel concrete to build is firm by stake and grade beam, make it to form whole, above grade beam, with steel concrete, build post straight up, then in the horizontal direction of many levels, use steel concrete casting beams, make to be rigidly connected between post and beam, facade is built shingle nail with steel concrete outside, by stake, grade beam, post, beam, shingle nail forms the framework of continous-stable, make frame body be rooted in stable soil supporting layer, and soil body lateral pressure is passed through to post, beam decomposes, reduce the soil body lateral pressure of shingle nail unit area, guarantee the stable and durability of retaining wall, increase retaining wall and resist the earthquake ability that even landslide and general natural calamity are destroyed, greatly reduce engineering safety hidden danger.
Described shingle nail is designed to cell structure, utilizes concrete cast-in-situ to build or prefabricated.
Described DESIGN OF RETAINING WALLS, for facing upward inclined structure, is applicable to the side slope that the gradient is less.
Described DESIGN OF RETAINING WALLS is upright structures, is applicable to vertical side slope.According to actual conditions, can be subdivided into again upright enclosed construction, upright Open architecture.
Described DESIGN OF RETAINING WALLS, for moving back mesa structure, is applicable to the side slope that the gradient is larger.
The utility model is simple in structure, adopt tower structure, frame body is rooted in to stable soil supporting layer, the lateral pressure of side slope soil layer is disperseed by beam and column, avoid body of wall local pressure excessive, increase that antiskid moves, shear resistance and bearing capacity, guarantee the stable and durability of retaining wall, engineering safety hidden danger be can greatly reduce, loosen soil, recent fill are applicable to and the banket slope soil in region of the heap that is difficult to reach closely knit is gone along with sb. to guard him and a gear.
