The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment one
As depicted in figs. 1 and 2, the catch basin assembly of this anti-dewatering installation adopts the fixing mode of catch basin, is used with steel plate stretching device 11.Pontic 1 upper strata is coated with bridge deck pavement 3, the pontic 2 of 1 both sides, shrinkage joint connects by steel plate stretching device 11, one end at both sides pontic 2 close shrinkage joint 1 is equipped with the mounting groove 4 of reservation, and anti-dewatering installation is fixed in the shrinkage joint 1 by the mounting groove 4 of both sides, shrinkage joint.
Anti-dewatering installation has mainly comprised two anchor bars 104, by two G shape catch basins 101, the catch basin assembly that inverted U-shaped movable deflector 102 is formed, and be arranged on the shrouding and the gutter 105 that is used for being connected the bridge storm sewer that catch basin assembly two ends are used for sealing.Wherein, the catch basin assembly has adopted the fixing mode of catch basin, and the notch of two G shape catch basins 101 is oppositely arranged, and towards the shrinkage joint 1, connects the anchor bar 104 of both sides respectively, is fixed in the mounting groove 4 by concreting, realizes its fixed installation.The both sides of inverted U-shaped movable deflector 102 are crossed on respectively in the notch of two G shape catch basins 101, can be movable between two G shape catch basins 101 along the width at shrinkage joint 1, thus satisfy the engineer to the requirement of bridge construction design aspect.Upper surface at inverted U-shaped movable deflector 102 is provided with for the stiffener that improves intensity.
Since about two G shape catch basins 101 can catchment respectively, so gutter 105 is provided with four, is separately positioned on the two ends of two G shape catch basins 101, is communicated with the storm sewer of G shape catch basin 101 and bridge.
In practical project was installed, anti-dewatering installation and steel plate stretching device 11 can be processed in factory, and this device can be divided into two main members to be made respectively, i.e. two G shape catch basins 101 and an inverted U-shaped movable deflector 102.G shape catch basin 101 can adopt the welding of four block plates to form, and must guarantee the sealing of commissure, and at the horizontal U-shaped anchor bar 104 of G shape catch basin 101 welding, the length of anchor bar 104 and spacing must satisfy structure and force request then.Shrouding and the gutter 105 at G shape catch basin 101 two ends are prepared in advance standby.Inverted U-shaped movable deflector 102 can adopt the welding of three block plates or compacting bending forming, welds stiffener 103 then thereon, and in the end of inverted U-shaped movable deflector 102, stiffener 103 is concordant with its maintenance, and requires to guarantee the sealing of weld seam.Then inverted U-shaped movable deflector 102 is crossed in the notch in the G shape catch basin 101, after activity flexible between check deflector and catch basin, corner meets the demands, shrouding and gutter 105 is installed in the two ends of G shape catch basin 101.
For the ease of the damage in transporting and avoiding installing, the temperature when installing according to bridge is on-the-spot, the width at actual measurement shrinkage joint 1 and bridge construction designing requirement etc., the spacing of regulating G shape catch basin is carried out two G shape catch basins temporary fixed.After the anti-dewatering installation with the whole series transports job site and installation in position to, build the concrete in the mounting groove 4, and gutter 5 is communicated with storm sewer, carry out the installation of follow-up caulking gum band 12 and steel plate stretching device 11 then.Like this, can be flowed in the G shape catch basin along inverted U-shaped movable deflector by whereabouts, shrinkage joint rainwater, catchment, discharge via storm sewer again by the gutter 5 at two ends then.
Embodiment two
As shown in Figure 3 and Figure 4, the catch basin assembly of this anti-dewatering installation adopts the mode of catch basin activity, is used with steel plate stretching device 11.The catch basin assembly has comprised two C shape expansion boxs 203 and a U-shaped active set tank 201, two C shape expansion boxs 203 offer the notch that is oppositely arranged respectively on a side at shrinkage joint 1, and the both sides of U-shaped active set tank 201 are crossed on respectively in the notch of two C shape expansion boxs, make it satisfy the engineer to the requirement of bridge construction design aspect along width activity between two C shape expansion boxs 203 at shrinkage joint.In addition, be provided with flase floor 202 (perhaps lacing wire) on the top of U-shaped active set tank 201.Owing to adopted a U-shaped active set tank 201, so gutter 105 arranges two, is separately positioned on the two ends of U-shaped active set tank 201, is communicated with the storm sewer of U-shaped active set tank 201 and bridge.The dilatation at 1 place is broken gutter for fear of the shrinkage joint, so gutter adopts bellows to be communicated with storm sewer.
Embodiment three
As shown in Figure 5, the catch basin assembly of this anti-dewatering installation adopts the fixing mode of catch basin, is used with shaped steel stretching device 21.Because stretching device has adopted different structures, requirement in conjunction with heavily loaded traffic, therefore at anti-dewatering installation and 21 of shaped steel stretching devices stiffener 300 is set, carry out fixedly connected, not only play the effect that G shape catch basin 101 is strengthened, but also played the fixedly effect of shaped steel stretching device 21.
