Problems solved by technology

Most of the tram lines currently built are built in the center of existing municipal roads. The traditional cast-in-place concrete construction method needs to set up a large number of formwork and tie steel bars on site, consumes a lot of manpower, has a long construction period, low efficiency, and seriously affects the surrounding areas. Roads bring inconvenience to the travel of surrounding residents, and the construction mode of on-site pouring is easily affected by factors such as weather seasons and the technical level of construction personnel, and the construction quality is difficult to guarantee

Abstract

The invention relates to an assembly type roadbed pile plate connecting structure. The structure comprises a plurality of prefabricated bearing plates which are sequentially spliced end to end, wherein every two adjacent prefabricated bearing plates are spliced through a connecting assembly, inserting blocks are symmetrically arranged at the two ends, in the splicing direction, of the prefabricated bearing plate, the inserting blocks are located on the lower surface of the prefabricated bearing plate, the connecting assembly comprises a prefabricated pipe pile and a first connecting assembly, and the first connecting assembly comprises a first connecting bolt and a first nut; the prefabricated pipe pile comprises a pile body and a concave bearing platform fixed to an end of the pile body, the inserting blocks located on the two adjacent prefabricated bearing plates are jointly inserted into the concave bearing platform, and the first connecting bolts penetrate through the concave bearing platform and the inserting blocks in the concave bearing platform and are fixed through first nuts. Compared with the prior art, the structure has advantages of high efficiency, small environmental pollution, strong reusability, convenience in maintenance and replacement, low cost and the like.

Description

technical field [0001] The invention relates to the field of transportation, in particular to an assembled roadbed pile-slab connection structure. Background technique [0002] Pile-slab structure subgrade is a new type of subgrade structure emerging with the development of high-speed railway. The bearing capacity of the piles and the soil between the piles can be fully utilized to jointly bear the load, meet the requirements for the strength, stiffness and stability of the track structure, and ensure the smooth operation of the train. [0003] In the construction of trams in deep soft soil areas, in order to meet the requirements of settlement control, pile-slab structure roadbed types are often used. Among the tram lines currently built, most of them are built in the center of existing municipal roads. The traditional cast-in-place concrete construction method needs to set up a large number of formwork and tie steel bars on site, consumes a lot of manpower, has a long con...
