Abstract
A reinforced cantilever retaining wall comprises a toe board, a panel and a heel board, wherein the toe board and the heel board are disposed side by side in the horizontal direction, and the lower end of the panel perpendicularly disposed is connected between the toe board and the heel board. The reinforced cantilever retaining wall further comprises a plurality of horizontally arranged and spaced tie bar layers above the heel board, one end of each tie bar is connected with the panel. The tie bar layers for enhancing slip resistance and upsetting resistance stability of the retaining wall are horizontally arranged above the heel board, one end of each tie bar is connected with the panel, no buttress is needed for the retaining wall, and thereby large-sized machines can be used for compacting soil during soil filling, construction speed is fast, quality is fine, work efficiency for the reinforced cantilever retaining wall compared with a buttress retaining wall can be increased by above 20%, construction period is shortened by 10%, and construction cost can be reduced greatly. Further, lengthening of the heel board is not needed by using the tie bar layers, and thereby masonry quantity for the reinforced cantilever retaining wall compared with a cantilever retaining wall can be reduced by 15%.
Description
Technical field
The utility model belongs to technical field of civil engineering, particularly relates to a kind of reinforcement cantilevered barricade.
Background technology
Cantilever and counterfort wall are two kinds of retaining structures commonly used in railway, highway, harbour and the construction work both at home and abroad at present, because these two kinds of retaining structures have simple in structure, easy construction, wall body cross section is less, sole mass is light, the easy advantage such as assurances of handsome in appearance and construction quality, thereby have obtained application widely in actual engineering.Fig. 1 is a kind of cantilevered wall-retaining structure stereogram of prior art.As shown in Figure 1, the cantilevered barricade of this prior art comprises toe board 1, panel 2 and heel slab 3; Wherein toe board 1 and heel slab 3 along continuous straight runs are arranged side by side; Panel 2 vertically is provided with, and its lower end is connected between toe board 1 and the heel slab 3.The stability of this retaining structure mainly is that the deadweight of dependence panel 2 and the fill stratum 6 that is laid on heel slab 3 tops guarantee.But, there is following point in this cantilevered barricade: when the height of panel 2 during greater than 6 meters, for stability against sliding and the stability against overturning that guarantees barricade, need to strengthen the length of heel slab 3, the quantity of masonry and the quantity of reinforcement of panel 2 are increased, so the construction costs height.In order to reduce the size of panel 2, common way is to set up a plurality of counterforts 4 that vertically are provided with between panel 2 and heel slab 3, and this barricade is counterfort wall, and its structure as shown in Figure 2.But there is following point in this counterfort wall: when setting up counterfort 4, the quantity of masonry of counterfort 4 also increases thereupon.In addition, as mentioned above, because counterfort 4 vertically is provided with, can only adopt small-sized machine that soil is carried out compacting when therefore above heel slab 3, laying fill stratum 6, so efficiency of construction is low, and construction quality is difficult to guarantee, and detects also very inconveniently, therefore can't be applied in the engineerings such as compacting and the demanding high-speed railway of examination criteria, Line for Passenger Transportation.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of can reduce construction costs, the reinforcement cantilevered barricade that efficiency of construction height and construction quality are good.
In order to achieve the above object, the reinforcement cantilevered barricade that provides of the utility model comprises toe board, panel and heel slab; Wherein toe board and heel slab along continuous straight runs are arranged side by side; Panel vertically is provided with, and its lower end is connected between toe board and the heel slab; Described reinforcement cantilevered barricade also comprises the lacing wire of being separated by multilayer the top that is horizontally set on heel slab and an end linking to each other with panel.
Described lacing wire is geosynthetics or concrete structure.
Described geosynthetics is high-strength geo-grid
The reinforcement cantilevered barricade that the utility model provides is in the heel slab upper horizontal lacing wire that multilayer is used to improve barricade stability against sliding and stability against overturning to be set, and an end of lacing wire is linked to each other with panel, because this barricade need not to be provided with counterfort, can adopt big machinery that soil pressure is real when therefore banketing, so the speed of construction is fast, quality good, compare work efficiency with counterfort wall and can improve more than 20%, the duration shortens 10%, and the result can reduce construction costs significantly.In addition, owing to adopted the multilayer lacing wire, therefore need not the length of heel slab that extends, so compare quantity of masonry with the cantilevered barricade and can reduce 15%.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the reinforcement cantilevered barricade that the utility model provides is elaborated.The parts identical with prior art adopt identical drawing reference numeral.
As shown in Figure 3, the reinforcement cantilevered barricade that provides of the utility model comprises toe board 1, panel 2 and heel slab 3; Wherein toe board 1 and heel slab 3 along continuous straight runs are arranged side by side; Panel 2 vertically is provided with, and its lower end is connected between toe board 1 and the heel slab 3; Described reinforcement cantilevered barricade also comprises the lacing wire 5 of being separated by multilayer the top that is horizontally set on heel slab 3 and an end linking to each other with panel 2.
Described lacing wire 5 is geosynthetics or concrete structure.
Described geosynthetics is high-strength geo-grid.
The work progress of reinforcement cantilevered barricade in a certain engineering that now the utility model is provided is described as follows: at first make toe board 1 according to traditional job practices, panel 2 and heel slab 3, begin then above heel slab 3, to banket, and adopt big machinery that soil pressure is real, when lacing wire 5 paving locations that are filled to basecoat, on the soil layer after the above-mentioned compacting, lay one deck lacing wire 5, and an end of lacing wire 5 is connected with built-in fitting in being embedded in panel 2 by not shown reinforcing rod, the high-strength geo-grid of 100kN/m is adopted in lacing wire 5, and position that built-in fitting is exposed and reinforcing rod adopt corrosion resistant coating and asphaltmastic to carry out preservative treatment afterwards.In above-mentioned lacing wire 5, continue again to banket then, compacting, re-lay one deck lacing wire 5 afterwards, so repeatedly, flush with panel 2 and compacting and form fill stratum 6 up to soil is filled to, finish the work progress of reinforcement cantilevered barricade thus.In addition, lacing wire 5 numbers of plies and width need to be determined by calculating according to the concrete condition of engineering.
