Abstract

The invention discloses a cement prefabricated part for high-speed rail construction and an installation method. The installation method comprises the steps step 1, prefabricating rail plates; step 2, pouring a base; step 3, mounting the rail plates; and step 4, pouring mortar; through the arrangement of positioning blocks and positioning grooves, quick positioning and mounting of two adjacent rail plates are achieved, meanwhile, through the arrangement of a splicing mechanism, accurate positioning and mounting between the rail plates are achieved, meanwhile, connection and fixation of the splicing mechanism are matched with pouring of CA mortar, and the connection strength between the rail plates is improved. Loosening and falling of the rail plates are avoided. The rail plate is simple in structure, convenient to manufacture and install and suitable for large-scale popularization; meanwhile, the mass of the rail plate is reduced due to the arrangement of the center groove, the manufacturing cost is reduced, rapid drainage of the rail plate is achieved through the design of the drainage groove and the drainage hole. And the problems of falling and strength reduction caused by rainwater erosion of the CA mortar layer are avoided.

Description

technical field [0001] The invention relates to the technical field of high-speed rail track construction, in particular to a cement prefabricated part for high-speed rail track construction and an installation method. Background technique [0002] Cement prefabricated parts are concrete components prefabricated in concrete in advance. They are mainly used to facilitate later construction or life. Cement prefabricated parts have a wide range of applications. Cement prefabricated parts are also required in high-speed rail track construction, and high-speed rail track slabs are important. Part; [0003] There are many types of such high-speed rail track slabs on the market today, which can basically meet people's needs for use, but there are still certain deficiencies. The specific problems are as follows; [0004] (1) During the installation process of the existing high-speed rail track slab, the positioning speed is slow and the efficiency is low, which greatly reduces the ...
