Description

The invention relates to the construction of underground utilities and can be used in particular in the construction of a collector-drainage network.

A known construction of a pipe-to-well connection assembly is the rigid end of a pipe, for example, asbestos cement, which enters a hole in the wall of a well.

However, the design of the assembly does not ensure the reliability of the connection in waterlogged subsidence soils, as a result of which when the well settles, the pipeline is destroyed.

The purpose of the invention is to improve the reliability of a well connection.

In FIG. 1 is a front view of the proposed joint; N.C. 2 is a section AA in FIG. 1.

The node connecting the manhole to the pipeline consists of a hole 1 in the housing of the pipe / s, and 2, into which the pipe 3, made with the possibility of transverse deformation and longitudinal

lengthening. A console 4 is installed on the outer surface of the body of the well 2 under the hole 1. A seal 5 is installed between the pipe 3 and the hole 1 for sealing. The horizontal side of the console 4 has a recess in the form of a half-cylinder, the axis of which coincides with the axis of the pipeline 3, and the inner diameter is larger than the external diameter of the pipeline 3. The length of the horizontal side of the console 4 is determined by

t Yh (4R -h),

where R is the minimum bend radius of the pipeline;

h is the calculated well settlement depth. The connection unit operates as follows. The presence of the console 4 on the outside of the body of the well 2 creates an additional area of support on the ground and reduces the settlement of the well 2. If the settlement of the well 2 does occur, the console 4 is lowered with it. Thus above the console 4 is formed free of soil space Ch

the state. The pipe 3, with the possibility of longitudinal extension and transverse deformation, is bent in the free space. Due to the fact that the horizontal side of the cantilever 4 has a recess in the form of a half-cylinder with an inner diameter larger than the outer diameter of the pipe 3, the curved pipe 3 is freely placed in the freed space in width.

The fulfillment of the condition t Yh (4 R - h) provides free bending of the pipeline 3.

Claims (2)

SUMMARY OF THE INVENTION 1. An assembly for connecting a pipeline to an inspection hole, including a seal 5 a clamping element installed in the side opening of the well for connecting a pipeline to it, characterized in that, in order to increase the reliability of connecting the flexible pipe when the well is upset, the assembly is provided with a horizontal console fixed to the outside of the well under its side opening, the width of which is greater than or equal to the external pipe diameter 2. The assembly according to claim 1, with the exception that the length of the C-console is determined by the dependence sYh- (4R -h), where R is the minimum bending radius of the pipeline; h is the calculated depth of the well. -H I1 .i Aa rie.2
