In figure, 1, square concrete body, 2, square gauze wire cloth, 3, prestressed steel bar, 4, reinforcement bar, 5, embedded nut, 6, bolt, the 7, first hornblock, the 8, first through hole, the 9, second hornblock, the 10, second through hole, 11, flexible rubber lagging.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the present invention will be described in detail.
As Figure 1-3, a kind of prestressed concrete flexible insert mouth anti-leakage Fang Han, comprise a square concrete body 1, in square concrete body 1 inside, along square concrete body 1 length direction, be provided with a square gauze wire cloth 2, on square gauze wire cloth 2, along the square gauze wire cloth 2 even intervals of length direction, be welded with some prestressed steel bars 3, on square gauze wire cloth 2, be evenly interval with the reinforcement bar 4 of some length and square concrete body consistency of thickness, in one end of square concrete body 1, be provided with taper bellmouth, the other end is provided with socket, taper bellmouth with on socket inwall, along square concrete body 1 inner surface circumferencial direction, be evenly interval with respectively the relative embedded nut in several positions 5, weld mutually with square gauze wire cloth 2 respectively the inner of embedded nut 5, on the embedded nut 5 of taper bellmouth inner surface, by bolt 6 and one side of several the first hornblocks 7, be connected, the another side of the first hornblock 7 is towards taper bellmouth outside and which is provided with the first through hole 8, on the embedded nut 5 of socket inner surface, by bolt 6 and one side of several the second hornblocks 9, be connected, the another side of the second hornblock 9 is towards socket outside and which is provided with the second through hole 10, the first hornblock 7 and the second hornblock 9 are symmetrical arranged, two first hornblocks 7 that position is relative and the first through hole 8 on the second hornblock 9 and the second through hole 10 positions align setting, outer surface at socket is fixed with a flexible rubber lagging 11 matching with taper bellmouth by tapping screw, outer surface at flexible rubber lagging 11 is provided with one deck adhesive-layer.
During construction, the ground trench bottom of excavation keeps smooth and compacting, lower slightly several centimeters of square concrete body 1 joint, so that square concrete body 1 socket end is put into, socket end at square concrete body 1 before docking puts flexible rubber lagging 11, and flexible rubber lagging 11 is fixed on to square concrete body 1 socket end outer surface in case flexible rubber lagging 11 displacements with tapping screw is fixing, loosening, during docking, keep adjacent two square concrete bodies 1 on a horizontal linear, two square concrete body 1 positions are not offset, flexible rubber lagging 11 does not damage, moreover, can be on flexible rubber lagging 11 brushing one deck adhesive-layer, to strengthen the sealing function of two square concrete body 1 joints.And at bellmouth and 5 places of the embedded nut on socket of square concrete body 1, the first hornblock 7 and the second hornblock 9 are installed, with high-strength connecting bolt 6, the first through hole 8 of adjacent the first hornblock 7 and the second hornblock 9 and the second through hole 10 are tightened up again, in one week direction symmetry of square concrete body 1 inwall, tighten up fastening, make 1 sealing of square concrete body more reliable, reach anti-leakage effect.
Square concrete body 1 has the various structures such as straight joint, elbow, threeway, four-way, five-way, is convenient to Fang Han branch, the maintenance that collects, goes into the well, widely applicable.The numerous municipal water supply pipelines in city, drainage pipe, heat distribution pipeline, gas pipeline, chemical pipeline, power cable, communication cable, network cable etc. can be installed concentratedly in Fang Han, be aided with automatic monitoring sniffer, personnel can easily enter walking, small-sized construction machinery can enter wiring comb, be not subject to inside even from weather, the inspection from now on of being more convenient for, maintenance, maintenance, dilatation etc.; Easy construction, duration be short, can reduce accident frequency rate.
The present invention does not describe part in detail, is those skilled in the art of the present technique's known technology.
