Background
The drain pipe mainly undertakes the drainage tasks of rainwater, sewage, farmland drainage and irrigation and drainage, etc. The drain pipe is divided into a plastic drain pipe, a Concrete Pipe (CP) and a reinforced concrete pipe, however, when the existing drain pipe is used, the pipeline displacement is caused by the change of temperature, and the normal drainage work of the drain pipe is influenced.
Disclosure of Invention
The present invention aims to overcome the above-mentioned shortcomings and provide a technical solution to solve the above-mentioned problems.
The installation method of the expansion joint of the drain pipe comprises the following steps:
s1, selecting a drain pipe and an expansion joint: selecting a drain pipe with the length of 4m and an expansion joint with the distance of 4 m;
s2, cleaning of a drain pipe and an expansion joint: cleaning the pipe end of the drain pipe selected in the step S1 and the socket of the expansion joint, and naturally airing the cleaned drain pipe and the expansion joint;
s3, mounting an expansion joint: and sleeving the pipe end of the drain pipe which is cleaned in the step S2 with the expansion joint which is cleaned in the step S2, inserting the pipe end of the drain pipe into a socket of the expansion joint, and installing the socket of the expansion joint against the water flow direction.
As a further scheme of the invention: the number of the expansion joints is determined according to the calculation of the calculated deformation of the drain pipe and the calculation of the allowable expansion amount of the expansion joints.
As a further scheme of the invention: the pressure-bearing performance of the expansion joint is 0.08 MPa.
As a further scheme of the invention: the reserved gap at the position where the pipe end of the drain pipe is inserted into the expansion joint is as follows: 5-10mm in summer; 15-20mm in winter.
Compared with the prior art, the invention has the beneficial effects that: the drain pipe is provided with the expansion joint by the installation method, so that the drain pipe can be protected from being damaged when the drain pipe is expanded with heat and contracted with cold, and the expansion joint and the contraction joint of the drain pipe can play a role in adjusting the expansion joint and the contraction joint of the drain pipe when the temperature of the long-distance drain pipe is changed due to expansion with heat and contraction with cold under the condition of ensuring no leakage, so that the drain pipe is prevented from being pulled apart or expanded and cracked.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The installation method of the expansion joint of the drain pipe comprises the following steps:
s1, selecting a drain pipe and an expansion joint: selecting a drain pipe with the length of 4m and an expansion joint with the distance of 4 m;
s2, cleaning of a drain pipe and an expansion joint: cleaning the pipe end of the drain pipe selected in the step S1 and the socket of the expansion joint, and naturally airing the cleaned drain pipe and the expansion joint;
s3, mounting an expansion joint: and sleeving the pipe end of the drain pipe which is cleaned in the step S2 with the expansion joint which is cleaned in the step S2, inserting the pipe end of the drain pipe into a socket of the expansion joint, and installing the socket of the expansion joint against the water flow direction.
As a further scheme of the invention: the number of the expansion joints is determined according to the calculation of the calculated deformation of the drain pipe and the calculation of the allowable expansion amount of the expansion joints.
As a further scheme of the invention: the pressure-bearing performance of the expansion joint is 0.08 MPa.
As a further scheme of the invention: the reserved gap at the position where the pipe end of the drain pipe is inserted into the expansion joint is as follows: 5-10mm in summer; 15-20mm in winter.
Example one
When the drainage pipe is a drainage vertical pipe, the length of the drainage vertical pipe is 4m, and each layer is provided with an expansion joint; when the length of the interlayer drainage riser is more than 4m, the number of the expansion joints is determined according to the calculation deformation of the pipeline and the allowable expansion amount of the expansion joints; when the drainage vertical pipe passes through the floor slab part and is not blocked, the maximum distance between the expansion joints is 4m, and the expansion joints are provided with fixed supports.
Example two
When the drainage pipe is a horizontal drainage pipe, a converging pipe fitting on the horizontal drainage pipe is arranged at the upper part of the floor slab and close to the floor, and an expansion joint is arranged above the converging pipe fitting; when the converging pipe fitting is arranged on the lower portion of the floor slab, an expansion joint is arranged on the lower portion of the converging pipe fitting.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
