Composite reinforced construction rubber pipe

Abstract

The invention discloses a composite reinforced construction rubber pipe, which comprises a pipe body and joints, wherein the pipe body is a multilayer composite pipe and comprises an outer rubber layer, a middle rubber layer and an inner rubber layer; multilayer wound high-tensile steel wires or steel wire bundles are distributed in the middle rubber layer and are well bonded with the rubber of the middle rubber layer to form a high-tensile composite reinforced layer; the space between the outer rubber layer and the middle rubber layer and the space between the middle rubber layer and the inner rubber layer are provided with a pressure rubber flat chafer fabric layer respectively; the joints are arranged at the two ends of the pipe body; each joint comprises a bushing and a wrap, is made of a high-tensile material and is subjected to electroplating antirust treatment, and heat treatment is performed on the bushing; and a buckling press process is performed between the bushing and the wrap as well as between the bushing and the rubber pipe. By the composite reinforced construction rubber pipe, the compression strength and the safety stock of the rubber pipe are greatly improved, the service life of the rubber pipe is prolonged, concrete delivery quantity of each pipe is increased by more than one time, uninterrupted construction can be realized, and the working efficiency is improved; and the rubber pipe has important value, particularly for the pouring of concrete with high volume.

Description

technical field [0001] This patent relates to a composite rubber hose, especially a composite reinforced construction rubber hose that is resistant to high pressure, abrasion (concrete scouring), ambient temperature in different regions or seasons, and sunlight exposure for concrete transportation and pouring in construction. Background technique [0002] Construction rubber hoses are widely used as concrete delivery pipes during concrete delivery and pouring, requiring them to have certain flexibility to facilitate construction, and they should also have high compressive strength, environmental resistance and service life. This kind of rubber hose currently used in building construction has some defects in materials, structure and manufacturing process, resulting in insufficient pressure resistance and wear resistance, and a short service life. Although there are continuous improvements, a new pipe can only transport About 10,000 cubic meters of concrete affects the constru...

Problems solved by technology

This kind of rubber hose currently used in building construction has some defects in materials, structure and manufacturing process, resulting in insufficient pressure resistance and wear resistance, and a short service life. Although there are continuous improvements, a new pipe can only transport About 10,000 cubic meters of concrete affects the construction efficiency; secondly, the connection reliability of the pipe joints is poor, and it is prone to "turn-around" accidents due to the connection flange pulling off; thirdly, the bonding between the layers of the pipe body is poor, often It was scrapped due to loss of adhesion, delamination, and peeling between layers, and even caused injury accidents caused by pipe explosion due to blockage of falling objects; fourth, the outer rubber of the pipe is prone to aging and cracking, which affects the service life
