Multifunctional free splicing type pipe pillow module and using method thereof

Abstract

The invention relates to multi-functional free splicing type pipe pillow modules and ausingmethod thereof. Semicircular cambered surfaces are arranged on the outer contours of the modules. The multi-functional free splicing type pipe pillow modules are characterized in that after two modules are relatively combined, the cross section of the whole outer contour is in a regular octagon shape, and a circular hole for bearing a pipeline is formed by two semicircular cambered surfaces; each component face, except for each semicircular cambered surface, of the outer contour of each module is provided with a columnar concave lock catch or a columnar convex lock catch extending in the longitudinal direction of the module, and the columnar concave lock catches and the columnar convex lock catches are adjacently arranged alternatively; and the outer contour of each module is provided with an annular groove parallel to the cross section of the module. The structural design of the multi-functional free splicing type pipe pillow modules is more reasonable, and the use is convenient and reliable; the fixation of one or multiple pipelines is achieved, and equal-distance location between pipes is maintained; the arrangement forms of the pipelines are variously arranged according to construction environment, and the construction operation is simple, and the work efficiency is remarkably improved; the material investment is saved, and the pipe arrangement construction is beautiful and standard; due to the modular design, the product production investment is reduced, and meanwhile the multi-functional free splicing type pipe pillow modules are suitable for pipeline buried construction and pipe jacking(drawing) construction; and the adaptation is high.

Description

technical field [0001] The invention relates to the fields of power cable engineering, pipeline engineering, and laying of single or multiple pipelines, in particular to a multifunctional free-splicing pipe pillow module and its application method. Background technique [0002] At present, in the pipeline laying project, in order to maintain the arrangement shape or spacing of the pipeline, the supports placed between the pipes are called "pipe pillows". From the material point of view, there are cement, plastic, and even metal parts. Cement components have the strongest pressure bearing capacity, but they are large in size and heavy, inconvenient to transport, and difficult to carry on the construction site; metal parts are heavy in weight and high in cost. Transportation is worse than plastic parts, and iron parts are prone to rust and corrosion; plastic parts are light in weight, small in size, low in cost, good in supporting the pipeline, and have good pressure bearing c...

Problems solved by technology

The above-mentioned pipe sleepers have the following problems: 1. The form of arranging pipelines is single; 2. The first and third types of pipe sleepers have a low degree of modularization. Although the second type of pipe sleepers has a slightly higher degree of modularity, there The two pipe pillows are connected by special pins. During the construction process, special pins need to be installed one by one, which affects the construction efficiency. At the same time, the special pins are conventional spare parts, which increases the construction cost and management burden; 3. The above three pipes The pillow is limited in the construction environment and use occasions. It is only suitable for laying pipelines in the pre-excavated soil layer, and cannot be used in the construction of jacking (pull) pipes. That is, the effect of the pipe pillow itself is greatly reduced after being used reluctantly. It even loses the control of the distance between the tubes and the support function, so the existing tube sleepers still have the problem of limited scalability and versatility
