Description

Lining expansion water stop rigid waterproof sleeve

Technical Field

The utility model relates to the technical field of waterproof parts of water storage structures, in particular to a liner expansion water stop rigid waterproof sleeve.

Background

When a gap between a rigid waterproof sleeve of a current water storage structure and a pipeline is plugged, the following methods are mainly adopted: oil-flax plugging, asbestos cement + sealant plugging. The main disadvantages of these methods are: (1) the worker's craft level is uneven, the filling is not solid and the leakage of the gap is easy to happen; (2) the plugging space is limited, workers have no operable space, and leakage still exists after plugging, so that the quality problem is caused.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the prior art, the utility model provides a liner expansion water stop rigid waterproof sleeve, which can enable a water stop belt to be tightly attached to a pipeline, and on the basis, the water stop rigid waterproof sleeve is plugged by asbestos cement, so that the phenomenon of leakage can be avoided.

The technical scheme of the utility model is detailed as follows:

a liner expansion water stop rigid waterproof sleeve comprises a steel sleeve and a steel pipe, wherein the steel pipe is sleeved in the steel sleeve, two wing plates are arranged on the inner wall of the steel sleeve, a water stop is arranged between the two wing plates, and the water stop is made of a water expansion rubber material; the outer wall of the steel pipe is provided with a check ring at a position corresponding to the water stop belt; the water stop belt compresses the check ring and is in close contact with the outer wall of the steel pipe, and plugging materials are filled between the steel sleeve and the steel pipe.

Optionally or preferably, in the liner expansion water-stop rigid waterproof casing, the outer wall of the steel casing is provided with a wing ring, and the wing ring is an annular steel plate perpendicular to the outer wall of the steel casing.

Alternatively or preferably, in the liner-expanded water-stop rigid waterproof casing, the wing ring is arranged at a position corresponding to the retainer ring.

Optionally or preferably, in the liner expansion water-stop rigid waterproof casing, the filling plugging material is asbestos cement.

Optionally or preferably, in the liner-expanded water-stop rigid waterproof sleeve, the height of the wing plate is less than the minimum height of the water stop after the water stop is squeezed.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, the two steel wing plates are arranged on the inner wall of the steel sleeve, the circle of water-swelling rubber water stop belt is fixed between the two wing plates, and the circle of check ring is arranged at the outer wall of the steel pipe corresponding to the position of the water stop belt, so that the check ring is just clamped at the position of the water stop belt when the steel pipe is sleeved in the steel sleeve, the water stop belt is limited by the check ring and is extruded between the steel sleeve and the two wing plates, and the tight fit between the water stop belt and a pipeline can be ensured without gaps. On the basis, the asbestos cement is adopted to block the rest gaps between the steel casing and the steel pipe, so that the leakage phenomenon can be avoided.

Detailed Description

The utility model is explained and illustrated in detail below with reference to the drawings and preferred embodiments so that those skilled in the art can better understand the utility model and implement it.

Example 1

Referring to fig. 1, a liner expansion water-stop rigid waterproof casing includes a steel casing 2 and a steel pipe 1, where the steel casing 2 needs to be poured into a wall in advance and fixed to the wall to allow the steel pipe 1 to pass through. The steel sleeve 2 welds a circle of wing ring 3 in outer wall a week, wing ring 3 is the annular steel sheet perpendicular with steel sleeve 2's outer wall, and wing ring 3 is used for consolidating the combination stability of steel sleeve 2 and wall body, also plays waterproof effect simultaneously. Two steel wing plates 4 are welded on the inner wall of the steel sleeve 2 at positions corresponding to the wing rings 3 for fixing the water stop belts 6. The distance between two pterygoid lamina 4 slightly is greater than the thickness of wing ring 3, and a recess is enclosed into jointly to two pterygoid lamina 4 and steel sleeve pipe 2's inner wall, recess internal fixation round waterstop 6, the material of waterstop 6 is for meeting water inflation rubber, and it is commercial commodity to meet water inflation rubber, mainly is a monocomponent, solvent-free polyurethane type sealed glue, has the elasticity stagnant water of rubber and meets the double containment stagnant water mechanism of the volume expansion stagnant water of water back self. The height of the wing plates 4 is smaller than the minimum height of the water stop 6 after being squeezed, so that a gap between the steel sleeve 2 and the steel pipe 1 caused by the supporting effect of the wing plates 4 under the condition that the water stop 6 is not squeezed fully is avoided. The height of the water stop belt 6 is larger than the distance between the steel sleeve 2 and the steel pipe 1, so that the steel pipe 1 can be fully extruded on the water stop belt 6 after being sleeved into the steel sleeve 2.

The steel pipe 1 has an outer diameter smaller than the inner diameter of the steel casing 2 so as to be able to penetrate into the steel casing 2. The outer wall of steel pipe 1 has the welding of round retaining ring 5 in the position that corresponds the waterstop, and after steel pipe 1 emboliaed steel sleeve pipe 2, waterstop 6 compressed tightly retaining ring 5 and with the outer wall in close contact with of steel pipe 1, guaranteed that the waterstop is inseparable with steel pipe 1 laminating, do not have the gap.

During construction, the steel sleeve 2 is poured into a wall body, the steel pipe 1 is sleeved into the steel sleeve 2, when the water stop belt 6 is clamped at the position of the check ring 5, the installation is in place, and finally, the gap between the steel sleeve 2 and the steel pipe is sealed by asbestos cement. The position of the

stop rings

5, 6 needs to be determined by measurement in advance.

Above-mentioned inside lining inflation stagnant water rigidity waterproof casing can effectively prevent the seepage phenomenon that probably exists after the gap shutoff between steel sleeve pipe and the steel pipe, has improved engineering quality.

The inventive concept is explained in detail herein using specific examples, which are given only to aid in understanding the core concepts of the utility model. It should be understood that any obvious modifications, equivalents and other improvements made by those skilled in the art without departing from the spirit of the present invention are included in the scope of the present invention.
