Underground pipeline construction mould

Abstract

The invention discloses an underground pipeline construction mould. The underground pipeline construction mould comprises an outer frame body with a groove-shaped section, wherein the front side of the outer frame body is sealed while the rear side thereof is open; a movable block capable of clamping and fixing the pipeline is arranged in each of the two sidewalls of the outer frame body respectively; a compression spring is arranged between the movable blocks and the two sidewalls of the outer frame body; a hydraulic oil cylinder is arranged on the front inner wall of the outer frame body; a push plate is installed at the terminal end of the hydraulic oil cylinder; a traction rope is arranged at the front outer wall of the outer frame body and is connected to a traction device. After the structure mentioned above is adopted, the two sides of the outer frame body block the collapse of the earthwork, and the movable blocks arranged in the outer frame body play a good positioning function during the pipeline installation process, so that the problems of multiple links of the installation construction, complex procedures and great work amount are solved, the installation and construction efficiency for the underground pipelines is improved greatly, the engineering cost is saved, and the safety hazard during the installation construction of the underground pipelines is avoided.

Description

[0001] technical field [0002] The invention relates to a device for underground pipeline construction, in particular to an underground pipeline construction mold. Background technique [0003] Existing large-scale pipeline construction and installation, especially in the deep underground, usually requires the use of multiple earth excavation machinery and equipment for excavation, and then after hoisting the pipeline, backfilling the earthwork, compacting the foundation and restoring the road surface, etc., use Although the existing construction method fulfills the engineering requirements, the method needs to excavate too much working face, which increases the workload of the underground pipeline installation project and the mechanical equipment used, and increases the construction cost of the underground pipeline installation. Moreover, the labor intensity is relatively high, and the required mechanical equipment must be completed by large-tonnage mechanical equipmen...
