Abstract
The utility model discloses a floor formula retaining wall, shingle nail (2) and outlet (3) on shingle nail (2) on basis (1), basis (1), its characterized in that: the equidistant consolidation of shingle nail (2) lin tumian has vertical floor (4), and shingle nail (2) between floor (4) are faced the facial position of soil and are equipped with loaded filter (5). This floor formula retaining wall is applicable to keeping off of steep side slope, embankment location or cutting abrupt slope location, and is little to the soil body disturbance during construction, requires lowly to the foundation bearing capacity, constructs with low costsly, easily promotes.
Description
Technical field
The utility model relates to a kind of slope earth-retaining wall, particularly relates to a kind ofly to be applicable to the retaining wall that gradient slope, embankment location or cutting steep slope region prop up gear.
Background technology
Retaining structure, comprises the form of structure such as retaining wall, antiskid (anchoring) stake, anchor cable (bar), is used to support, strengthening fill or slope soil, prevents from collapsing and slide with a kind of building keeping it stable.Retaining wall is supporting construction the most frequently used in engineering construction, be mainly used in supporting embankment filled soil or slope soil, prevent from banketing or soil deformation unstability, bear soil body lateral earth pressure, its purposes mainly comprises: (1) reduces execavated rockmass height, reduce excavation quantity, avoid natural slope failure slump; (2) shrink embankment toe, reduce fill yard and floor space, ensure roadbed reclamation; (3) avoid roadbed along river to squeeze contracting riverbed, prevent current scour roadbed.
For gradient slope, embankment location or cutting steep slope region etc., side slope is high and precipitous, the shallow-layer soil body is difficult to, domatic fixing or destroy the original balance of massif due to dig on a wide area ground, need to arrange retaining structure and prevent slope soil or cunning of collapsing of banketing, and conventional at present have gravity retaining wall.Gravity retaining wall maintains retaining wall stablizing under lateral earth pressure effect with the deadweight of wall body, and wall body, from great, makes to produce larger frictional force with basic earth at the bottom of wall, thus balance wall back of the body active earth pressure.Multiplex sheet (block) barnacle that grouts of gravity retaining wall is built, and lacks building stones area and sometimes with concrete precast block as masonry, or directly can use concreting, be generally unworthy of reinforcing bar or only configure a small amount of reinforcing bar at subrange.This barricade form is simple, easy construction, can gather materials on the spot, applied widely.But in engineering practice, also there is following problem in gravity retaining wall: during the construction of (1) gravity retaining wall, the first excavation slope soil body from top to bottom, masonry panel or build walls concrete from the bottom up again, when body of wall is higher, whole excavated surface is large and suddenly, produce strong unloading disturbance to original slope soil, slope collapsing slide when easily causing constructing, especially more outstanding in heavy cut location; (2) gravity retaining wall relies on self gravitation to maintain balance and stability, thus from great, high to ground requirement for bearing capacity, earthen foundation is built the restriction being often subject to bearing capacity; (3) when barricade is higher, it is large that wall body cuts volume, and bricklaying quantity is large, uneconomical.
Utility model content
The purpose of this utility model is to provide a kind of fin-plate type retaining wall, and this fin-plate type retaining wall is applicable to gradient slope, embankment location or propping up of cutting steep slope region and keeps off, little to soil disturbance during construction, low to ground requirement for bearing capacity, constructs cost low, is easy to promote.
The utility model realizes the technical scheme that its goal of the invention adopts, a kind of fin-plate type retaining wall, comprise the shingle nail on basis, basis and the spilled water hole on shingle nail, its design feature is: described shingle nail faces that native face is equally spaced is consolidated with vertical floor, and the shingle nail between floor faces native facial position and is provided with loaded filter.
The construction method of above-mentioned fin-plate type retaining wall is:
A. in slope soil, excavate the vertical slot mated with floor;
B. in the vertical slot of a step, the connecting reinforcement of connection wall panel also reserved by colligation floor reinforcing bar, and in vertical slot, concreting forms the floor exposing connecting reinforcement subsequently;
C. excavate shingle nail foundation trench, build basis by laying bricks or stones;
D. on basis, colligation shingle nail reinforcing bar, and shingle nail reinforcing bar is connected with connecting reinforcement, then set up shingle nail template, and pre-buried spilled water hole pipe, finally concreting in shingle nail template, after concrete setting, remove shingle nail template, form shingle nail;
E. the shingle nail between floor faces native facial position and lays loaded filter, backfills the soil body subsequently and tamps, until wall top between loaded filter and side slope.
When engineering-environment is not suitable for cast in situs, prefabricated units also can be adopted to carry out assembling construction, make the utility model applied widely, be conducive to promoting the use of.
Compared with prior art, the beneficial effect of fin-plate type retaining wall of the present utility model is:
When floor space is larger, after wall, the plane of fracture of the soil body is arranged in the soil between adjacent floor, and floor stretches in the stable soil body after the plane of fracture.Utilize the frictional resistance stablize between soil body inner rib plate sidewall and the soil body to conduct oneself with dignity with shingle nail and floor and jointly bear soil body lateral earth pressure, realize keeping off propping up of slope soil.Only bear soil body lateral earth pressure by body of wall deadweight than existing Gravity Retaining Wall, its gear effect obviously strengthens.
When fin-plate type floor space is less, intercostal soil is subject to the effect of floor side friction power, mobilely together with floor forms overall cob wall, and the plane of fracture is arranged in the soil body after floor end.The soil pressure that after the overall cob wall be made up of shingle nail, floor and the intercostal soil body bears wall jointly, the soil body produces, realize the gear to slope soil, only bear soil body lateral earth pressure by body of wall deadweight than existing Gravity Retaining Wall, its gear effect obviously strengthens especially.
In a word, than gravity retaining wall, a gear effect for the utility model fin-plate type retaining wall obviously strengthens, and overall concrete consumption is reduced, and bricklaying quantity is few, lightweight, low to ground requirement for bearing capacity, constructs cost low, is easy to promote.
Construction method of the present utility model is simple, only need at the groove of the vertical alternation excavation of slope soil and floor adaptation, make use of slope soil from steady characteristic, decrease earth excavation workload to greatest extent, can ensure that on the one hand vertical slot is stablized, reduce temporary lining engineering quantity, priorly be the reduction of the disturbance of construction to original slope body, improve working security, also ensure that the stability of slope soil and good supporting effect.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
