Abstract

The utility model discloses a sealing ring, relating to a leakage-prevention sealing element which is connected with a city drainage pipeline and an inspection well. The sealing ring has a trapezoidal structure, is made of natural rubber and is arranged at a contact position of a plastic pipe and a well pipe of the inspection well, the plastic pipe passes through a well wall of the inspection well and is connected with the inspection well, concrete is added between the well wall of the inspection well and the plastic pipe, and the sealing ring is fixed between the concrete and the plastic pipe. The utility model has the advantages that the sealing ring can be much conveniently and firmly fixed at an end head of a plastic pipeline, is ensured to be tightly sealed with the concrete under the action of expansion of the sealing ring, the problem of leakage is solved, environment friendliness is promoted, and the sealing ring is simple in structure and is convenient to operate.

Description

Seal ring

Technical field

The utility model relates to the municipal engineering field, particularly a kind ofly solves the ladder type sealing material that the municipal drainage plastic pipe is connected with inspection shaft and prevents seepage.

Background technique

At present, when the municipal drainage plastic pipe in city was connected with inspection shaft, pipe surface directly contacted with body of wall; Perhaps the filling concrete seals between body of wall and pipeline.After the engineering completion,, certain stretching rate is arranged, just the slit occurs easily between plastic pipe and body of wall and the concrete, the effluent seepage phenomenon occurs because plastic tube itself is intrinsic; Structure and groundwater resources around polluting.

Summary of the invention

For solving the problem that prior art exists: the utility model provides a kind of termination that can be fixed on plastic pipe conveniently and solidly, the effect assurance and the non-leakage seal ring of concrete tight seal that rely on seal ring to expand.

Address the above problem, the technological scheme that the utility model adopted is: the sealing circle is the trapezium structure of natural rubber system, and the upper end of trapezium structure is that 100mm, lower end are that 50mm, both sides are respectively 200mm.At plastic tube and the inspection shaft borehole wall touching position seal ring is installed, plastic tube passes the inspection shaft borehole wall and links to each other with inspection shaft, between the inspection shaft borehole wall and plastic tube, adds concrete, and seal ring is fixed between concrete and the plastic tube.

The beneficial effect of the utility model, be seal ring can be very convenient the firm termination that is fixed on plastic pipe, the effect assurance and the concrete tight seal that rely on seal ring to expand, the solution leakage problems helps environmental protection; It is simple in structure, and is easy to operate.

Embodiment

The ladder type seal ring is installed seal rings 1 in water drainage plastics pipeline and the inspection shaft borehole wall 5 contacted parts, and the sealing circle can the very convenient firm termination that is fixed on plastic pipe, and the effect assurance and the concrete tight seal that rely on seal ring to expand are non-leakage.According to pipeline elevation that plastic tube 2 is fixing; When plastic tube 2 links to each other with the inspection shaft borehole wall 5; Plastic tube termination point casing ladder type seal ring passes the inspection shaft borehole wall 5 with plastic tube 2 and links to each other with inspection shaft, between the inspection shaft borehole wall 5 and plastic tube 2, adds concrete 3 and pours into a mould; The ladder type seal ring just is fixed between concrete 3 and the plastic tube 2, plays the impermeable effect of sealing.

Claims

1. seal ring, it is characterized in that: the sealing circle is the trapezium structure of natural rubber system, the upper end of trapezium structure is that 100mm, lower end are that 50mm, both sides are respectively 200mm.

2. a kind of seal ring according to claim 1; It is characterized in that: seal ring (1) is installed at plastic tube (2) and the inspection shaft borehole wall (5) touching position; Plastic tube (2) passes the inspection shaft borehole wall (5) and links to each other with inspection shaft; Between the inspection shaft borehole wall (5) and plastic tube (2), add concrete (3), seal ring is fixed between concrete and the plastic tube (2).
