Municipal garden drainage pipe sleeve compensator

Abstract

The invention discloses a municipal garden drainage pipe sleeve compensator. The municipal garden drainage pipe sleeve compensator comprises an end pipe, a working corrugated pipe, a middle connectingpipe and a balance corrugated pipe; the end pipe is connected with a protective cover; a baffle plate is on one side of the protective cover; one end of the baffle plate is fixedly connected to the inner wall of the protective cover; a gap is formed between the other end of the baffle plate and the protective cover; the protective cover is provided with a water outlet; the water outlet is positioned on the protective cover near one side of the baffle plate; a first guide device is arranged between the inner walls of the end pipe and the middle connecting pipe; protective lugs and first pull rods are respectively arranged on the outer walls of the end pipe and the middle connecting pipe; a second guide device is arranged in middle of the middle connecting pipe; and protective lugs and second pull rods are arranged on the middle connecting pipe. The compensator is arranged between municipal garden drainage pipes for compensating radial and angular displacements of the drainage pipes toachieve an excellent compensation effect, so that the drainage pipes are not easy to rupture in thermal expansion and cool shrinkage, and sewage is not easy to flow out; and the compensator is novel and simple in structure, low in cost, convenient to mount and suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of municipal gardens, in particular to a casing compensator for drainage pipes in municipal gardens. Background technique [0002] Municipal gardens mainly include municipal and road engineering, environmental landscape engineering, landscaping engineering, urban and road lighting engineering construction, etc. Among them, municipal and road engineering is an important part, and municipal drainage pipeline engineering in municipal and road engineering is The main components are implemented in a wide range, including road drainage pipeline engineering, community drainage pipeline engineering, garden drainage pipeline engineering, venue drainage pipeline engineering, etc. Garden drainage pipeline engineering is mainly used for municipal garden drainage, which is the main factor to ensure the development of municipal gardens. One of the means. [0003] Municipal gardening is one of the tasks of the government serving th...

AI Technical Summary

Problems solved by technology

The main problems are: 1. Municipal garden drainage pipes are set in the soil, which is easily eroded by moisture in the soil. The life of the compensator is short and easy to be eroded and damaged; 2. Thermal expansion and contraction of municipal garden drainage pipes mainly occur in winter, and the temperature in summer is relatively high. When it is high, it is generally not suitable to swell, so the compensator installed on the municipal garden drainage pipeline has time requirements, especially to adapt to the compensation of the pipeline at low temperature in winter; 3. The municipal garden drainage pipeline is easily eroded by sewage and microorganisms, so Set compensators are equally susceptible to erosion
