Summary of the invention:
The present invention is in order to make up the deficiencies in the prior art, provide a kind of prestressed concrete flexible insert mouth anti-leakage Fang Han, its reasonable in design, adopt the square concrete body be made into integration, anti-leakage is effective, switching performance is good, shock resistance is high, water resistance is good, and anti-bending strength is high, is not easy cracking and sinks, be not easy by native crimp, long service life, assembling speed is fast, efficiency is high, Functionality, quality and appealing design, solves problems of the prior art.
The present invention for solving the problems of the technologies described above adopted technical scheme is:
A kind of prestressed concrete flexible insert mouth anti-leakage Fang Han, comprise a square concrete body, a square gauze wire cloth is provided with along square concrete body length direction in square concrete body inside, some prestressed steel bars are welded with at square steel wire top line of the net square gauze wire cloth length direction uniform intervals, on square gauze wire cloth, uniform intervals is provided with the reinforcement bar of some length and square concrete body consistency of thickness, taper bellmouth is provided with in one end of square concrete body, the other end is provided with socket, on taper bellmouth with socket inwall along square concrete body inner surface circumferencial direction respectively uniform intervals be provided with the relative embedded nut in several positions, the inner of embedded nut is welded mutually with square gauze wire cloth respectively, by bolt and several the first hornblocks on the embedded nut of taper bellmouth inner surface while be connected, the another side of the first hornblock is outside taper bellmouth and which is provided with the first through hole, by bolt and several the second hornblocks on the embedded nut of socket inner surface while be connected, the another side of the second hornblock is outside socket and which is provided with the second through hole, first hornblock and the second hornblock are symmetrical arranged, the first through hole on two first hornblocks that position is relative and the second hornblock and the second lead to the hole site align setting, a flexible rubber lagging matched with taper bellmouth is fixed with by tapping screw at the outer surface of socket.
One deck adhesive-layer is provided with at the outer surface of flexible rubber lagging.
The present invention adopts such scheme, reasonable in design, adopts the square concrete body be made into integration, high by steam curing of concrete intensity, at more than C60, concrete component has prestressing force, anti-leakage is effective, and switching performance is good, shock resistance is high, water resistance is good; Square gauze wire cloth is provided with in square concrete body inside, square gauze wire cloth is welded with prestressed steel bar, square gauze wire cloth is provided with reinforcement bar, make square concrete body anti-bending strength high, be not easy cracking to sink, be not easy by native crimp, long service life, assembling speed is fast, efficiency is high, Functionality, quality and appealing design, greatly reduces cost of labor.

Detailed description of the invention:
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, 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, a square gauze wire cloth 2 is provided with along square concrete body 1 length direction in square concrete body 1 inside, square gauze wire cloth 2 is welded with some prestressed steel bars 3 along square gauze wire cloth 2 length direction uniform intervals, on square gauze wire cloth 2, uniform intervals is provided with the reinforcement bar 4 of some length and square concrete body consistency of thickness, taper bellmouth is provided with in one end of square concrete body 1, the other end is provided with socket, on taper bellmouth with socket inwall along square concrete body 1 inner surface circumferencial direction respectively uniform intervals be provided with the relative embedded nut in several positions 5, the inner of embedded nut 5 is welded mutually with square gauze wire cloth 2 respectively, by bolt 6 and several the first hornblocks 7 on the embedded nut 5 of taper bellmouth inner surface while be connected, the another side of the first hornblock 7 is outside taper bellmouth and which is provided with the first through hole 8, by bolt 6 and several the second hornblocks 9 on the embedded nut 5 of socket inner surface while be connected, the another side of the second hornblock 9 is outside socket and which is provided with the second through hole 10, first hornblock 7 and the second hornblock 9 are symmetrical arranged, the first through hole 8 on two first hornblocks 7 that position is relative and the second hornblock 9 and the second through hole 10 position align setting, a flexible rubber lagging 11 matched with taper bellmouth is fixed with by tapping screw at the outer surface of socket, one deck adhesive-layer is provided with at the outer surface of flexible rubber lagging 11.
During construction, the ground trench bottom of excavation keeps smooth and tamps, lower slightly several centimeters of square concrete body 1 joint, so that square concrete body 1 socket end is put into, flexible rubber lagging 11 on the front cover of the socket end at square concrete body 1 of docking, and with tapping screw is fixing, flexible rubber lagging 11 is fixed on square concrete body 1 socket end outer surface in case flexible rubber lagging 11 is shifted, loosen, keep adjacent two square concrete bodies 1 during docking on a horizontal linear, two square concrete body 1 positions are not offset, flexible rubber lagging 11 does not damage, moreover, can on flexible rubber lagging 11 brushing one deck adhesive-layer, to strengthen the sealing function of two square concrete body 1 joints.And the first hornblock 7 and the second hornblock 9 is installed at embedded nut 5 place on the bellmouth and socket of square concrete body 1, with high-strength connecting bolt 6, first through hole 8 of adjacent first hornblock 7 and the second hornblock 9 and the second through hole 10 are tightened up again, tighten up fastening in square concrete body 1 inwall one circumferential direction symmetry, make square concrete body 1 seal more reliably, 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, collects, maintenance of going into the well, widely applicable.Can numerous for city municipal water supply pipeline, drainage pipe, heat distribution pipeline, gas pipeline, chemical pipeline, power cable, communication cable, network cable etc. be installed concentratedly in Fang Han, be aided with automatic monitoring sniffer, personnel easily can enter walking, small-sized construction machinery can enter wiring comb, not by inside even from weather, the inspection, maintenance, maintenance, dilatation etc. of being more convenient for from now on; Easy construction, duration be short, can reduce accident frequency rate.
The present invention does not describe part in detail, is the known technology of those skilled in the art of the present technique.
