Description
Technical field
The utility model relates to a kind of Reinforced Concrete Retaining Walls structure with combination of steel rope, and particularly a kind of place of bearing down on one on Reinforced Concrete Retaining Walls wall body, toe of wall, wall heel, wall arranges the Novel retaining wall structure of multiple anchor cable.Belong to highway engineering field, be applicable to highway, railway slope, hydraulic engineering bank and watch out for the construction of the reinforcing bar retaining wall in engineering such as protecting.
Background technology
Retaining wall refers to supporting Roadbed Soil or the hillside soil body, prevent from banketing or the structure of soil deformation unstability, have simple in structure, take up an area less, easy construction and the plurality of advantages such as cheap.At present, retaining wall is not only widely used in highway, railway, urban construction, is also applied to the fields such as dam construction, riverbed regulation, port works, water and soil conservation, the reallocation of land, landslide control simultaneously.
The primary load that retaining wall bears is soil pressure, water pressure, wall weight, and top imposed load.Under the compound action of these loads, stable state, the stress performance of retaining wall constantly change, and especially, when environmental factor generation ANOMALOUS VARIATIONS, retaining wall structure there will be damage in various degree, even there is destabilization problems, the constructing benefits of engineering and duration are had a negative impact.
The existing barricade with anchor cable has two kinds: the one, and with the retaining wall of oblique pull anchor cable, this retaining wall, after wall body has been constructed, carries out the oblique hole of drawing, then carries out the construction of oblique pull anchor cable.This anchor cable outer end is fixed on domatic, the other end is anchored at slide plane with in interior rock mass stability, directly on sliding surface, produce sliding resistance, increase antiskid frictional resistance, make structural plane in impaction state, to improve the globality of slope rock mass, thereby fundamentally improve the mechanical property of rock mass, effectively control the displacement of rock mass, impel it stable, reach the object of regulation concordant, landslide and crag, danger stone.A kind of is retaining wall with vertical anchor cable, this anchor cable is by anchor cable being set in cast-in-place concrete wall body and carrying out pre-stretch-draw, on wall top, apply lasting vertical pressure effect, make full use of anti-pressure ability and the higher bearing capacity of ground that concrete wall body is stronger, increased the active force between retaining wall and ground, part has replaced the active force being produced by body of wall deadweight, meeting under the prerequisite of wall stability, can reduce wall body cross dimensions, thereby reach the object that reduces excavation quantity and construction area area, shortens the engineering time.
Two kinds of above-mentioned modes have obtained good consolidation effect under suitable engineering specifications, but still deposit certain deficiency, as oblique pull anchorage cable anchoring to wall after soil bearing capacity have relatively high expectations, and long construction period, engineering cost are high; Vertical anchor cable is higher to the requirement for bearing capacity of foundation soil body.In sum, a kind of place of bearing down on one on Reinforced Concrete Retaining Walls wall body, toe of wall, wall heel, wall arrange the Novel retaining wall structure of multiple anchor cable can be corresponding the requirement for bearing capacity of the soil body, foundation soil body after wall, the anchor cable of varying number is set accordingly.Given this, need at present the Novel retaining wall structure that a kind of place of bearing down on one of invention arranges multiple anchor cable badly on Reinforced Concrete Retaining Walls wall body, toe of wall, wall heel, wall.
Summary of the invention
The object of the present invention is to provide a kind of place of bearing down on one on Reinforced Concrete Retaining Walls wall body, toe of wall, wall heel, wall that the Novel retaining wall structure of multiple anchor cable is set.
In order to realize above-mentioned technical purpose, the present invention has adopted following technical scheme:
A Reinforced Concrete Retaining Walls structure with combination of steel rope, is characterized in that, at cantilever retaining wall toe of wall and wall heel place, is being provided with the first vertical anchor cable; At cantilever retaining wall wall, be in and be provided with the second vertical anchor cable; After cantilever retaining wall wall body and wall, in the original soil body, be provided with oblique injecting cement paste and horizontal anchor cable; The end of the first vertical anchor cable arranges and expands termination, and external part is provided with ground tackle; The second vertical anchor cable and the laterally end of anchor cable are provided with expansion steel plate; Before cantilever retaining wall, fill and solidify backfill.
Described vertical anchor cable and laterally anchor cable are evenly arranged in after cantilever retaining wall and wall in the soil body.
Described oblique injecting cement paste is along retaining walls towards tilted, and gradient is 1% ~ 20%.
The free end outsourcing protective sleeve of the described second vertical anchor cable, protective sleeve material can adopt PVC, PE or HDPE.
In wall body front, plain concrete being set every beam, is to take as crosspoint, to build plain concrete formation through the ground tackle anchor head of mortar packet header processing.
the utlity model has following beneficial effect and feature:
(1) on Reinforced Concrete Retaining Walls toe of wall, wall heel, wall, bear down on one and locate to arrange prestress anchorage cable, increase the active force between Reinforced Concrete Retaining Walls and ground, improve stability against sliding and the stability against overturning of reinforced concrete retaining wall.
(2) laterally the end of anchor cable and the second vertical anchor cable is provided with expansion steel plate, is more convenient to apply prestressing force, and construction all adopts reservation mode to imbed retaining wall, easy construction.
(3) the vertical anchor cable of prestressing force is set at Reinforced Concrete Retaining Walls place, directly on sliding surface, produce sliding resistance, increase antiskid frictional resistance, make structural plane in impaction state, to improve the globality of slope rock mass, thereby fundamentally improve the mechanical property of rock mass, effectively control the displacement of rock mass, impel it stable, reach the object of regulation concordant, landslide and crag, danger stone.
(4) oblique slip casting physical efficiency strengthens the stability of retaining wall.
