Description
Technical field
The utility model relates to a kind of abutment accessory structure, especially a kind of abutment accessory structure reducing soil pressure after platform.
Background technology
In the construction of urban road network, cross over the urban small grade separation without ramps bridge of road intersection and to occur now and then, unavoidably.As everyone knows, this kind of bridge need consider that pedestrian and motorway pass through, specify according to " urban road highway route design specification ", nonmotorized vehicle lane longitudinal gradient should not be greater than 2.5%, meeting by under the condition of dealings road 4.5-5m headroom, if reduce road and bridge division altitude in order to soil pressure after reducing platform, bridge length certainly will lengthen, if long and increase road and bridge division altitude in order to control bridge, abutment must adopt Large-diameter Pile Group basis to bear soil pressure after larger platform.Above-mentioned two situations all can increase project scale and construction costs, it is necessary to a kind of reasonably abutment accessory structure of design, help abutment when road and bridge, division altitude was higher, soil pressure after platform can be effectively reduced, make abutment that the basic normal use that can ensure abutment of Single row pillars only need be set, and the abutment accessory structure that can meet this requirement is at present actually rare.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of abutment accessory structure that can effectively reduce soil pressure after platform.
According to the technical scheme that the utility model provides, a kind of abutment accessory structure reducing soil pressure after platform, comprise abutment, abutment comprises the abutment body, cushion cap, the pile foundation that set gradually from top to bottom, it is characterized in that: arrange the pull bar vertical with abutment body on rear side of the platform of described abutment body, pull bar is provided with anchor slab away from one end of abutment body; After the platform of described abutment body, soil pressure effect centre of form place is provided with abutment reinforcing bar, is provided with reinforcing steel bar of pull rod in pull bar, is provided with anchor slab reinforcing bar in anchor slab, one end two-sided welding of abutment reinforcing bar and reinforcing steel bar of pull rod, the other end of reinforcing steel bar of pull rod and anchor slab reinforcing bar binding.
The weld of described abutment reinforcing bar and reinforcing steel bar of pull rod adopts flexible corrosion protection layer way, namely after welding completes, swathes two-layer with asphalt jute or Glass Cloth in Asphalt, then makes the cross section identical with pull bar with asphalt mortar, bituminous mortar.
Described abutment is the thin wall-type abutment on Single row pillars basis, and pull bar is cast-in-situ steel reinforced concrete rod member, and anchor slab is cast-in-situ reinforced concrete slab.
The utility model farthest can reduce soil pressure after the platform of abutment, thus the normal use making abutment only need arrange Single row pillars basis can to ensure under road and bridge division altitude higher strip part, reach and shorten bridge length, reduce project scale and reduce the object of construction costs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2: after described reduction platform, the abutment accessory structure of soil pressure comprises abutment 1, pull bar 2, anchor slab 3, abutment reinforcing bar 4, reinforcing steel bar of pull rod 5, anchor slab reinforcing bar 6 etc.
The utility model comprises abutment 1, abutment 1 comprise from top to bottom set gradually abutment body 1-1, cushion cap 1-2, pile foundation 1-3; Arrange the pull bar 2 vertical with abutment body 1-1 on rear side of the platform of abutment body 1-1, pull bar 2 is provided with anchor slab 3 away from one end of abutment body 1-1; After the platform of abutment body 1-1, soil pressure effect centre of form place is provided with abutment reinforcing bar 4, is provided with reinforcing steel bar of pull rod 5 in pull bar 2, is provided with anchor slab reinforcing bar 6 in anchor slab 3, one end two-sided welding of abutment reinforcing bar 4 and reinforcing steel bar of pull rod 5, the other end of reinforcing steel bar of pull rod 5 and anchor slab reinforcing bar 6 colligation; Wrap up in layers of asphalt burlap outside described abutment reinforcing bar 4 and the weld of reinforcing steel bar of pull rod 5, asphalt jute applies asphalt mortar, bituminous mortar anticorrosive coat; Described abutment 1 is the thin wall-type abutment on Single row pillars basis, and pull bar 2 is cast-in-situ steel reinforced concrete rod member, and anchor slab 3 is cast-in-situ reinforced concrete slab.
Operating principle of the present utility model and the course of work:
When abutment 1 is constructed after platform the pre-buried abutment reinforcing bar 4 in soil pressure effect centre of form place, abutment 1 bankets after carrying out platform after having constructed, slot respectively place reinforcing steel bar of pull rod 5 and anchor slab reinforcing bar 6 according to pull bar 2, anchor slab 3 shape after being filled to abutment reinforcing bar 4 place, one end of reinforcing steel bar of pull rod 5 is welded with abutment reinforcing bar 4 pre-buried in abutment abutment body, the other end of reinforcing steel bar of pull rod 5 stretch into anchor slab 3 and with anchor slab reinforcing bar 6 colligation, pull bar 2, anchor slab 3 are built in last scene simultaneously, make pull bar 2, anchor slab 3 in aggregates with abutment 1 shape, jointly bear soil pressure;
Pull bar 2 carrys out soil pressure after balancer by the frictional force of banketing after concrete and platform, and the pulling force that rod member 2 produces is resisted by the reinforcing steel bar of pull rod 4 of self; Anchor slab 3 carrys out soil pressure after balancer by passive earth pressure, and the pulling force that anchor slab 3 produces is resisted by rod member reinforcing bar 4; Principle appear on the stage after soil pressure balanced by the frictional force of pull bar 2 completely, the passive earth pressure of anchor slab 3 is only as safety stock; By this kind of mode, farthest can reduce soil pressure after the platform of abutment 1, thus the normal use making abutment 1 need arrange Single row pillars basis can to ensure under road and bridge division altitude higher strip part, reach and shorten bridge length, reduce project scale and reduce the object of construction costs.
