Problems solved by technology

[0003] The traditional way of cleaning and dredging mostly uses steel bars, electric drills and other rigid damage to the channel body, which is easy to cause the bellows joints inside the channel to roll over, and the treatment effect is not obvious for long, curved and variable cross-section channels. Based on this, a flexible and fast solution is designed. It is still necessary to clean the dredging hole device

Abstract

The invention provides an elastic prestress duct dredging device. The elastic prestress duct dredging device comprises an elastic dredging device, a main cable type pull rod and an auxiliary cable type pull rod, wherein one end of the elastic dredging device is in screw joint with the auxiliary cable type pull rod, and the main cable type pull rod is inserted into the other end of the elastic dredging device; the elastic dredging device comprises a fixed guide cup and a free guide cup; a bidirectional connecting piece is fixedly assembled at the upper end of the fixed guide cup; two sets of inner bolt holes are in screw joint with one ends of high-strength spring steel sheets; a hollow duct is fixedly assembled at the lower end of the free guide cup; the auxiliary cable type pull rod is inscrew joint with the upper side of the bidirectional connecting piece; and the main cable type pull rod penetrates the hollow duct and is in screw joint with the lower side of the bidirectional connecting piece. Through the combination of the device, ducts with unlimited lengths, bent and variable cross sections can be cleaned in a single-end and two-end dredging manner. The elastic prestress duct dredging device does not damage the ducts, the aperture range is large, operation and maintenance are convenient, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of pipeline dredging, and specifically relates to an elastic prestressed hole dredging device and a use method thereof. Background technique [0002] With the rapid development of my country's construction material technology and continuous improvement of construction capacity, in recent years, my country's municipal, highway, railway and other structures have developed in the direction of high span, novel technology and combined assembly. The post-tensioning prestressing technology is mostly used in its concrete structures. However, foreign matter such as slurry and sealant in the prestressed channel makes it difficult to penetrate the beam. [0003] The traditional way of cleaning and dredging mostly uses steel bars, electric drills and other rigid damage to the channel body, which is easy to cause the bellows joints inside the channel to roll over, and the treatment effect is not obvious for long, curved a...
