Description
Technical Field
The utility model relates to a cantilever type barricade structure that is used for bubble concrete to trade and fills out road bed.
Background
The air bubble concrete has the advantages of light weight, compression resistance, integrity, low elasticity and shock absorption, economy, easy construction and the like, and is widely used as a roadbed filling material in projects of soft highway sections, abutment backfilling, road extension widening and the like. The cantilever type retaining wall is a light supporting and retaining structure, and is small in structural size, light in self weight and good in slope collecting effect, so that a filling road section with low foundation bearing capacity is often used as a road shoulder retaining wall, but the use of the cantilever type retaining wall has certain limiting conditions, and the specification clearly requires that the using height of the cantilever type retaining wall is not more than 6m, because the section size of the retaining wall needs to be correspondingly increased after the wall exceeds a certain height, the economy is poor, and the anti-skidding and anti-overturning capacities are also poor. When the cantilever type retaining wall is used as a shoulder retaining wall of a roadbed for replacing and filling bubble concrete, the lateral soil pressure of the retaining wall is lower, so that the cantilever type retaining wall has the advantage of being capable of improving the wall height without increasing the wall thickness; meanwhile, the wall height is increased and the weight of the earth filled on the upper part of the bottom plate is reduced, so that the anti-bending, anti-sliding and anti-overturning capacity is reduced.
Therefore, in order to meet the working condition that the height of the air bubble concrete replacement roadbed exceeds 6m, a novel cantilever type retaining wall combination structure is needed to be provided, so that the cantilever type retaining wall still has enough bending resistance, skid resistance and overturning resistance under the condition that the height of the wall is increased without increasing the section size.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a convenient to use, simple structure, stability is good, can still have sufficient bending resistance, cling compound and antidumping ability be used for the cantilever type barricade structure that the bubble concrete traded and filled the road bed under the circumstances that promotes the wall height and does not increase cross sectional dimension.
In order to solve the above problem, the utility model adopts the following technical scheme:
the utility model provides a cantilever type barricade structure for bubble concrete trades fills out road bed, trades by cantilever type barricade, anchor rope, steel concrete basement membrane and bubble concrete and fills out the road bed and constitute, the steel concrete structure that the cantilever type barricade was pour as an organic whole, the cantilever type barricade includes that the barricade founds wall, heel board, toe board and tenon, and the barricade founds the wall and is equipped with the anchor rope with heel between the board, anchor rope one end is fixed at heel board front end, and the other end is fixed on the barricade founds wall upper portion, the steel concrete basement membrane is located bubble concrete and is traded and is filled out road bed and cantilever type barricade between the heel board, and pavement structure lays and trades on the road bed is filled out at bubble concrete.
Preferably, the cantilever type retaining wall the retaining wall founds the wall upper end and is equipped with the anchor head, and the anchor head is connected with the anchor rope.
Preferably, the distance between adjacent anchor cables along the length direction of the vertical wall of the retaining wall is not less than 2 m; when the height of the cantilever type retaining wall is higher, a group of parallel anchor cables can be added between the middle part of the vertical wall of the retaining wall and the middle part of the heel plate.
Preferably, the thickness of the thin layer of the steel concrete bottom film is not less than 10 cm.
The utility model has the advantages that: through the collocation that cantilever type barricade and aerated concrete trade fill the road bed, make the cantilever type barricade can promote the wall height and do not increase wall thickness, through add the anchor rope between barricade founds wall and heel board, improved the compressive capacity that the barricade founds the wall, the steel concrete basement membrane has improved the antidumping ability of cantilever type barricade simultaneously, the tenon provides the cling compound ability of barricade simultaneously to overcome the reduction of filling soil weight and to the adverse effect of barricade stability, let the cantilever type barricade can fully exert inherent advantage and extend its range of application.
Drawings
In order to illustrate the embodiments of the present invention or the technical solutions in the prior art more clearly, the drawings used in the description of the embodiments or the prior art will be briefly described below, but the protection scope of the present invention is not limited thereto.
Fig. 1 is a schematic structural view of the present invention;
the concrete foundation comprises a retaining wall vertical wall 1, toe boards 2, heel boards 3, tenons 4, anchor cables 5, anchor heads 6, a pavement structure 7, a roadbed filled with bubble concrete 8 and a steel concrete bottom film 9.
Detailed Description
Referring to the cantilever type barricade structure that a road bed was traded and is filled out to bubble concrete that shows of figure 1, trade by cantilever type barricade, anchor rope 5, steel concrete basement membrane 9 and bubble concrete and fill out road bed 8 and constitute, the steel concrete structure that the cantilever type barricade was pour as an organic whole, the cantilever type barricade includes that barricade founds wall 1, heel board 3, toe board 2 and tenon 4, and the barricade founds and is equipped with anchor rope 5 between wall 1 and the heel board 3, anchor rope 5 one end is fixed at heel board 3 front end to through welding or articulated connection, the other end is fixed on barricade founds wall 1 upper portion, steel concrete basement membrane 9 locates the bubble concrete and trades and fills out road bed 8 and cantilever type barricade between the heel board 3, and pavement structure 7 is laid on bubble concrete trades and fills out road bed 8.
Further, cantilever type barricade the barricade founds the wall 1 upper end and is equipped with anchor head 6, and anchor head 6 is connected with anchor rope 5.
Further, the distance between adjacent anchor cables 5 along the length direction of the vertical wall 1 of the retaining wall is not less than 2 m; when the height of the cantilever type retaining wall is higher, a group of parallel anchor cables 5 can be added between the middle part of the retaining wall vertical wall 1 and the middle part of the heel plate 3.
Further, the thickness of the thin layer of the steel concrete basement membrane 9 is not less than 10 cm.
Furthermore, the aerated concrete filled roadbed can also be paved with a layer of reinforcing mesh on the upper part of the aerated concrete filled roadbed so as to enhance the integrity of the roadbed and reduce the lateral deformation of the roadbed.
The utility model discloses because of the lateral soil pressure that the bubble concrete trades and fills the road bed and founds the wall to the cantilever type barricade is less, therefore the cantilever type barricade can promote the wall to 6 ~ 10m, and wall thickness still is 20 ~ 25cm, when expanding cantilever type barricade application height, still keeps its economic nature and better slope effect of receiving, has improved land use rate.
The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
