Description

Shrinkage water retaining device for urban sewage well opening

Technical Field

The invention relates to the technical field of underground pipeline engineering, in particular to a shrinkage water retaining device for an opening of an urban sewage well.

Background

With the development of the country, the urban population is continuously increased, the living requirements of people are also continuously improved, the occupied resources are also greatly improved, the original sewage disposal pipe network of the city is not enough, and a new pipe network needs to be built to meet the development requirements. The urban pipe network is a complex, and connection between new and old pipe networks is required to be established, but the living of citizens cannot be stopped, so that the pipe networks cannot be connected after interception. In general, a new pipeline is connected with an inspection well of an old pipe network, and a hole is formed in a well wall under the condition that pressurized water exists in the well, and underwater operation is generally performed by a diver, but the sewage well has small space and high flow rate, the underwater operation of the diver has high risk and high cost, the blockage of a pipeline gap is difficult to meet the design requirement, and a large amount of sewage in the well flows into a construction groove. Accordingly, the prior art is still in need of improvement and development.

Disclosure of Invention

The invention aims at overcoming the defects and shortcomings of the prior art, and provides the shrinkage water retaining device for the urban sewage well opening, which has the advantages of reasonable structure, convenience in operation and capability of avoiding underwater operation.

In order to achieve the above purpose, the present invention adopts the following technical scheme:

the invention relates to a shrinkage water retaining device for urban sewage well tapping, which comprises a water retaining plate, a water-proof strip and a steel cable, and is characterized in that: the two water baffles are arranged in a V shape, the inner sides of the two water baffles are connected through a hinge to form an openable integrated structure, the outer side of the hinge is provided with a waterproof skin, two sides of the waterproof skin are respectively bonded on the outer sides of the two water baffles, waterproof strips are arranged on the outer sides and the bottom edges of the water baffles, and two ends of a plurality of steel ropes are respectively fixedly connected with the two water baffles to form a stable triangular structure.

According to the scheme, the outer side edge and the bottom edge of the water baffle are respectively provided with a pressing plate for fixing the waterproof strip, and the pressing plates are connected with the water baffle through bolts.

According to the scheme, the waterproof strip is a P-type rubber water stop strip.

According to the scheme, a plurality of stiffening crosspieces are arranged on the inner side face of the water baffle, and are welded on the water baffle at intervals in sequence.

According to the scheme, the stiffening crosspieces are provided with the fixing rings connected with the steel cables, and two ends of the steel cables are respectively connected to the corresponding fixing rings.

The invention has the beneficial effects that: the invention has reasonable structure, the water baffle is folded and then put into the inspection well, the inspection well is opened to the maximum opening angle after the inspection well reaches the position of a large section, the inspection well is placed on one side of the hole to be opened and is abutted against the inner wall of the well, so that the water baffle is in full contact with the bottom of the well, then a water suction pump is put between the water baffle and the well wall for pumping water, the water baffle can be tightly pressed on the well wall under the action of water pressure, a steel cable can be automatically tensioned and bear the expanding tension, and a rubber water stop strip can be tightly clung to the well wall to form a seal, thereby realizing the operation of waterless opening.
