Pipeline bushing-penetrating construction device and construction method thereof

Abstract

The invention discloses a construction device and a construction method for pipes passing through casing pipes. At least two supporting rollers are arranged under the core pipe and arranged along the axial direction of the core pipe. The core pipe can slide on the supporting rollers; the ports of the core pipe are detachably connected Multiple guide wheels. First place the casing to be threaded horizontally, select an appropriate number of idlers according to the length of the core pipe, arrange the idlers below the core pipe in sequence from the end of the core pipe along the axis of the core pipe, and then place the core The tube is placed on the supporting roller, and a guide wheel is installed at the port of the core tube, and the core tube is pushed into the casing, and when the port of the core tube passes through the other end of the casing, the guide wheel is removed. There is no direct contact between the core tube and the casing when the core tube is threaded. When the core tube advances in the casing, the roller supports the core tube to keep it relatively parallel to the casing. Roll forward in the middle, directly push the core tube to move the core tube forward, no other equipment is required to provide thrust, which can reduce a lot of costs, and the operation is simple and safe.

Description

technical field [0001] The invention relates to the field of pipeline engineering construction, in particular to a pipeline casing construction device and a construction method thereof. Background technique [0002] Pipeline transmission is one of the most widely used transportation methods in industry and civil use, and it can transport fluid media in various industries. Due to the limited ground space in the municipal pipeline network and pipeline laying in industrial parks, the installation of pipelines is generally carried out by burying. If the casing is to be constructed in the casing, the core pipe needs to be inserted into the casing. The traditional construction method of the pipe through the casing is to place the casing horizontally, tie a sling to the core pipe, and the construction personnel cooperate with the crane to insert the front end of the core pipe into the casing for a short distance, and then use the crane to lift the end of the core pipe. Lift off th...

The traditional construction method of the pipe through the casing is to place the casing horizontally, tie a sling to the core pipe, and the construction personnel cooperate with the crane to insert the front end of the core pipe into the casing for a short distance, and then use the crane to lift the end of the core pipe. Lift off the ground, and then rotate the crane arm to pull the core pipe into the casing, but the control accuracy of the core pipe is very poor when using the crane for construction, which will cause a serious offset between the axis of the core pipe and the casing, resulting in a large angle. As a result, the anti-corrosion layer on the outer surface of the core pipe will scratch against the casing mouth, the ground or the inner surface of the casing, causing damage to the anti-corrosion layer and seriously affecting the construction quality; in addition, when the crane is lifting the end of the core pipe, the hook of the crane and the pipe The inertia is large, it will shake back and forth, the core tube is easy to fall off the sling, and the safety factor is low
