Assembly type cement pavement construction method

Abstract

The invention relates to an assembly type cement pavement construction method. A leveling layer is arranged on the lower portion of an assembly board, and a starting point assembly board, a middle assembly board and an end assembly board are laid on the upper portion of the leveling layer in sequence; a positive step interface and an inverted step interface are arranged in the connection positions of the assembly boards correspondingly; the end portions of the outer sides of a starting point end assembly board and a terminal point end assembly board are provided with lateral sway prevention buttresses and displacement side limiting pile connection holes; after the assembly boards are laid, displacement side limiting piles are driven into a lower structural layer of a pavement through the displacement side limiting pile connection holes; and finally, post-glue injection construction is conducted on seams and a seam resisting steel board is installed. The procedures are simple, the construction period of the cement concrete pavement can be greatly shortened, and various damages of the cement pavement can be prevented effectively.

Description

technical field [0001] The invention relates to a construction method for an assembled cement concrete pavement, which belongs to the field of road engineering and is suitable for new construction or reconstruction projects of cement concrete pavement with tight construction period and high environmental requirements. Background technique [0002] As the main structural form of road pavement, cement concrete pavement still occupies a considerable proportion in my country's low-grade roads. Considering that the cast-in-place cement pavement has the advantages of good integrity and high rigidity, the current cement pavement mostly adopts the cast-in-place cement pavement. However, the cast-in-place cement pavement is prone to plate cracking, mud pumping, and voiding at the bottom of the slab during use. and other diseases seriously affect the driving comfort of the road; in addition, the cast-in-place cement pavement also has shortcomings such as long construction period, seri...

AI Technical Summary

Problems solved by technology

Although this structure can increase the connection strength between the plates and improve the performance of the prefabricated concrete slab, it is difficult to solve the problems of temperature stress damage of the concrete slab and vehicle vibration damage, and the structure is prone to local stress concentration

[0005] To sum up, the prefabricated cement pavement has a wide range of engineering application prospects. Although some explorations have been carried out on the prefabricated cement pavement structure in the project, and corresponding prefabricated structures have been proposed. These structures have achieved relatively good results under suitable working conditions. The engineering effect is good, but there are still some deficiencies in the coordination of the forces between the boards, the prevention and control of road surface diseases, and the improvement of road performance.
