Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, for the utility model discloses a box culvert seal structure, including pour in the pad roof beam 1 on ground and a plurality of box culverts 2 of pouring on pad roof beam 1, box culvert 2 is square tubular structure, and a plurality of box culverts 2 distribute and mutual end to end along the length direction who fills up roof beam 1, are formed with the lap joint between the adjacent box culvert 2.
Referring to fig. 2 and 3, the end surfaces of the two ends of the box culvert 2 are provided with overlapping edges 21 in a step-shaped structure, the surface of each overlapping edge 21 faces away from the central axis of the box culvert 2, and the transition surfaces between the adjacent steps of the overlapping edges 21 are inclined at an angle of 45 degrees. The reinforcing bar of predetermineeing in the adjacent box culvert 2 is worn out respectively and is formed with connecting reinforcement 22, and connecting reinforcement 22 is on a parallel with the central axis of box culvert 2, is provided with a plurality of connecting pieces 23 in the lap joint to a plurality of connecting reinforcement 22 interconnect with adjacent box culvert 2. And a lap joint structure 3 is formed in the lap joint seam by pouring and filling waterproof concrete. Wherein the connecting steel bar 22 is screw steel.
When using, because overlap edge 21 is the echelonment structure, and 45 jiaos of slope setting are personally submitted in the transition between the adjacent ladder of overlap edge 21, can effectually increase the route that water infiltration needs to extend, with the possibility that reduces water from the clearance infiltration between overlap edge 21 and the overlap joint structure 3, connecting piece 23 connects the connecting reinforcement 22 in adjacent box culvert 2 simultaneously, even make box culvert 2 take place the dislocation, still can make overlap joint structure 3 under connecting piece 23 and connecting reinforcement 22's effect, comparatively inseparable relatively laminate in overlap edge 21, with the sealed effect that keeps relative preferred, simultaneously, elastic sealing strip 31 can be sealed to the clearance in overlap edge 21 and the 3 outsides of overlap joint structure, reduce the water that enters into between overlap edge 21 and the overlap joint structure 3, with further optimize the sealed effect to between the adjacent box culvert 2.
Referring to fig. 3 and 4, the connecting member 23 includes two opposite open-ended semi-circular pipes 231, the two semi-circular pipes 231 are coaxial, a plurality of clamping ring platforms 232 for clamping the connecting steel bars 22 are fixedly connected to the inner wall of the semi-circular pipe 231, and the opposite ends of the connecting steel bars 22 on the adjacent box culvert 2 are respectively clamped between the two semi-circular pipes 231. Wherein, two semicircle pipes 231 are turned over outwards respectively and are formed with flange 234 to the side border in opposite directions, and flange 234 of two semicircle pipes 231 laminates mutually and passes through bolt fixed connection. For clamping and connecting the facing ends of the connecting bars 22 on adjacent culverts 2.
Clamping ring platform 232 is right trapezoid along the axial cross-section of semicircle pipe 231, and a plurality of clamping ring platforms 232 on same semicircle pipe 231 divide into two sets ofly, and two sets of clamping ring platforms 232 distribute along the axial of semicircle pipe 231, and the hypotenuse of the right trapezoid in two sets of clamping ring platforms 232 cross-sections is located two sets of clamping ring platforms 232 back of the body one side that leaves respectively. So that splice bar 22 is by the centre gripping when between two semicircle pipes 231, joint ring platform 232 butt in splice bar 22's outer wall, and joint ring platform 232's cross-section is right trapezoid, can effectually increase flesh joint ring platform 232 restriction to splice bar 22 to increase the stability of connecting between the splice bar 22 of adjacent box culvert 2, thereby optimize the stability of 3 sealed effects to the overlap joint of overlap joint structure.
A connecting rod 233 for connecting the adjacent connecting members 23 is arranged between the adjacent connecting members in the same lap joint seam, and the connecting rod 233 can be welded to the semicircular tube 231. With the intensity that is used for increasing 3 overall structure of overlap joint structure when using, reduce because of adjacent box culvert 2 misplaces and lead to 3 structural damages of overlap joint structure to take place, lead to the probability that the sealed effect of overlap joint structure 3 reduces.
Meanwhile, in order to further increase the sealing performance between the lap joint structure 3 and the lap joint edge 21, at least one sealing pipe 33 for further sealing is arranged between the lap joint structure 3 and the lap joint edge 21, the sealing pipe 33 is arranged around the central axis of the box culvert 2, part of the sealing pipe 33 is embedded in the lap joint structure 3, and the other part of the sealing pipe 33 is embedded in the box culvert 2; the sealing tube 33 is a water-swellable rubber tube. In order to be used for making taking place the dislocation or use for a long time at box culvert 2, when leading to the clearance increase between overlap joint structure 3 and the overlap edge 21, sealed tube 33 can follow and do elastic deformation, keep laminating in the state of overlap joint structure 3 and box culvert 2 outer wall, in order to keep the sealed effect to between overlap joint structure 3 and the overlap edge 21, sealed tube 33 is for meeting water inflation rubber tube simultaneously, can be when water infiltration to sealed tube 33, sealed tube 33 can expand and make its inseparabler laminating in overlap joint structure 3 and overlap edge 21, in order to optimize sealed tube 33's sealed effect.
Referring to fig. 2 and 3, since the elastic sealing strip 31 is used for initial water penetration resistance and is relatively easy to detach, a plurality of connecting protrusions 32 distributed in an array are integrally formed on one side of the elastic sealing strip 31 facing the box culvert 2, and the connecting protrusions 32 are embedded in the lap joint structure 3. Wherein the connecting protrusion 32 is T-shaped, and the T-shaped horizontal portion thereof is embedded in the overlapping structure 3.
So that when in use, the connecting strength between the elastic sealing band 31 and the lap joint structure 3 can be effectively increased through the connecting protrusions 32, the probability that the elastic sealing band 31 is separated from the lap joint structure 3 is reduced, and the waterproof and seepage-proof effect of the elastic sealing band 31 can be effectively maintained.
A plurality of connecting anchor bolts 24 are preset around the opening edges at the two ends of the box culvert 2, and the elastic sealing strip 31 deviates from the box culvert 2 and is coated with a fastening steel plate 34 on one side. The fastening steel plate 34 is disposed around the central axis of the box culvert 2, and the plurality of connecting bolts 24 at the same end of the box culvert 2 are disposed around the central axis of the box culvert 2. The connecting anchor bolt 24 sequentially penetrates through the edge of the elastic sealing band 31 and the edge of the fastening steel plate 34, and one end, far away from the box culvert 2, of the connecting anchor bolt 24 is in threaded connection with a nut which enables the fastening steel plate 34 to be tightly attached to the elastic sealing band 31. So that when using, can compress tightly elastic sealing strip 31 under the effect of connecting crab-bolt 24 and nut through fastening steel sheet 34 for do the fastening to elastic sealing strip 31's both sides border, make the whole relatively inseparabler laminating in the outer wall and the overlap joint structure 3 of box culvert 2 of elastic sealing strip 31, optimize the stability that elastic sealing strip 31 is sealed, can do certain protection to elastic sealing strip 31 simultaneously, make the result of use better relatively.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
