Abstract
The utility model discloses a waterproof wall bushing, it includes sleeve pipe, wing ring, flexible sealing ring, fender ring, connecting plate, flexible bed course, bolted connection spare, stiffening rib, suppresses the hole, wherein the wing ring with the sleeve pipe connecting plate welded connection, keep off the ring with bushing welded connection, the stiffening rib with the connecting plate bushing welded connection, the flexible bed course with the connecting plate passes through bolted connection spare is connected, twice flexible sealing ring with the sleeve pipe encloses into the confined space of suppressing, the embedding of flexible sealing ring in the space that the fender ring encloses, suppress the hole and arrange in between the twice flexible sealing ring. The water seepage at the through-wall position of the pipeline can be avoided, and the installation quality can be checked by pressing before construction, so that the safe operation of equipment and valves in the underground structure is ensured.
Description
Technical Field
A waterproof wall bushing, in particular to a waterproof wall bushing which can effectively prevent the pipeline wall bushing of an underground water structure from permeating into the structure and ensure the safe operation of equipment in the structure in water conservancy, municipal water supply and drainage and other large-diameter pipeline engineering of industrial and mining enterprises.
Background
In water conservancy, municipal water supply and drainage engineering and other industrial and mining enterprises large-diameter pipelines, when buried pipelines pass through the wall of a structure, waterproof treatment needs to be carried out at the wall-penetrating position so as to prevent underground water from permeating into the structure from the wall-penetrating position of the pipeline and further damage equipment, valves and the like in the structure. The existing engineering technical means mainly adopts the steps that a steel sleeve with a larger caliber is additionally arranged on the periphery of a wall penetrating part of a wall penetrating pipe, and a gap between the wall penetrating pipe and the sleeve is plugged by using materials such as oil hemp, sealing paste, cement mortar and the like. Such a waterproof sleeve technique by plugging the plugging material has the following disadvantages:
firstly, the wall bushing can generate periodic expansion and contraction due to the change of the environmental temperature or the internal fluid pressure, and after the wall bushing operates for a period of time, gaps can be generated among the sealing material, the pipeline and the bushing, so that underground water cannot be prevented from permeating into the structure to cause flooding equipment;
secondly, in the process of pipeline installation, when the wall bushing and the waterproof bushing are eccentric due to installation errors, the filling space of the plugging material is uneven, and the construction process of the oil-hemp wound pipeline cannot ensure that the gap between the wall bushing and the waterproof bushing is completely filled, so that water seepage is caused;
thirdly, the construction result cannot be tested by the prior art, whether water seeps at the through-wall part of the pipeline can be tested only after the pipeline is backfilled or during the operation of a main body of the engineering, and the safe operation of equipment, valves and the like in a structure is difficult to guarantee;
fourthly, when the pipe diameter of the wall bushing is larger, the existing wall bushing is formed by bending and forming a steel plate and then welding the steel plate, and the production process is complex;
fifthly, the existing wall bushing is a round pipeline after being molded, and needs to be specially fixed in the transportation process, so that the difficulty and the transportation cost of the transportation link can be increased.
Disclosure of Invention
The utility model aims at providing a waterproof wall bushing to the not enough of prior art.
The technical solution of the utility model is as follows:
the utility model provides a waterproof wall bushing, its includes sleeve pipe, wing ring, flexible sealing washer, keeps off ring, connecting plate, flexible bed course, bolted connection spare, stiffening rib, suppress the hole, wherein the wing ring with the sleeve pipe the connecting plate welded connection, keep off the ring with sleeve pipe welded connection, the stiffening rib with the connecting plate sleeve pipe welded connection, the flexible bed course with the connecting plate passes through bolted connection spare is connected.
The two flexible water stop rings and the sleeve surround a closed pressing space, and the flexible water stop rings are embedded into the space surrounded by the retaining rings.
And the pressing hole is arranged between the two flexible water stop rings.
The beneficial effects of the utility model reside in that:
when the wall bushing expands and contracts due to changes of environmental temperature or internal fluid pressure, the flexible water stop ring can correspondingly expand and contract to deform, so that the water stop ring is tightly connected with the bushing and the wall bushing steel pipe, and water seepage can be effectively prevented.
Suppress hole, flexible sealing washer, fender ring through the setting, can be right after the construction is accomplished the utility model discloses the sleeve pipe is suppressed the experiment and is detected, ensures the water-proof effects of pipeline wall penetrating department.
The utility model discloses the sleeve pipe adopts the split structure, is formed by two semi-circular steel sheet combinations, need not the roll welding, and production simple process is reliable.
The utility model discloses the sleeve pipe adopts the split structure, is formed by two semi-circular steel sheet combinations, and in the transportation, semi-circular sleeve pipe can pile the transportation, and the transportation mode is simple and convenient, can practice thrift the cost of transportation greatly.
