Problems solved by technology

[0003] At present, the pavement of domestic airports generally adopts the construction technology of cast-in-place concrete. There are many wet operations, the concrete curing time is long, the surface layer of the pavement is complicated, the construction quality is extremely high, and the overall construction period is long.
When an emergency occurs, the traditional cast-in-place concrete construction technology cannot satisfy the ability of rapid construction

Embodiment 1

[0025] see Figure 1~3 , the prefabricated road panel connection structure based on tongue-and-groove bolt connection, including a precast concrete road panel 1, a convex groove 2, a concave groove 3, a reserved installation groove 4, a reserved hole 5 and a curved bolt 6; the precast concrete The four sides of the road panel 1 are arranged with concave grooves 2 and convex grooves 3, and the precast concrete road panel 1 is symmetrically provided with reserved installation grooves 4 and reserved channels 5, and the upper surface of the precast concrete road panel 1 is provided with four hoisting The grouting hole 10; the precast concrete pavement 1 is fixed by the socket connection of the convex groove 2, the concave groove 3 and the bent bolt 6; the precast concrete pavement 1 is prefabricated by light inorganic materials.

[0026] In the embodiment of the present invention, the prefabricated concrete pavement 1 is manufactured by factory prefabrication, and the groove 2, th...

Embodiment 2

[0032] The installation method of the prefabricated road panel connection structure based on the tongue-and-groove bolt connection, the installation method includes the following steps:

[0033] 1) Complete the construction of the base course of the airport road, and ensure that the airport has a certain strength, rigidity and flatness, so as to meet the assembly construction requirements of the precast concrete road slab 1 of the subsequent road;

[0034] 2) Base-level positioning and setting out. According to the overall division of the working surface, each working surface determines the positioning of the starting plate respectively, and places a positioning line at a certain distance to prevent the accumulated error of the plate from being too large;

[0035] 3) For the laying of the precast concrete pavement slab 1, the component slabs prepared in advance are accurately placed on the starting slab position through the hoisting equipment, and the subsequent slabs are laid ...

Abstract

The invention discloses a prefabricated pavement slab connecting structure based on tongue-and-groove bent bolt connection and an installation method. The prefabricated pavement slab connecting structure comprises a prefabricated concrete pavement slab, a convex tongue-and-groove, a concave tongue-and-groove, a reserved installation groove, a reserved hole channel, a bent bolt, a fixing steel plate, a nut, a filling material and a hoisting grouting hole. The prefabricated concrete pavement slab connecting structure has the beneficial effects that the prefabricated concrete pavement slab connecting structure is simple, the prefabricated concrete pavement slab is single in slab type, industrial production is facilitated, and the problem that spliced slab types are not uniform and disordered does not need to be considered on site. Due to the design of the arc-shaped chamfer of the precast concrete pavement slab, damage to corners is reduced in the processes of production, transportation, storage, construction and later airplane rolling. The prefabricated concrete pavement slab assembly is machined in a factory and transported to a site to be hoisted and installed, the industrialization degree is high, site installation is convenient, the construction speed is high, good economic benefits and social benefits are achieved, and the prefabricated concrete pavement slab assembly is suitable for rapid assembly construction of airport pavements.

Description

technical field [0001] The invention relates to a prefabricated concrete pavement, in particular to a prefabricated pavement connection structure and an installation method based on tongue-and-groove bolt connection, and belongs to the technical field of airport pavement construction. Background technique [0002] Prefabricated concrete pavement construction technology, less wet work on site, fast construction, industrialized production, and guaranteed quality of pavement panels. [0003] At present, cast-in-place concrete construction technology is generally used for domestic airport pavement, which requires a lot of wet work, long concrete curing time, complicated pavement surface layer technology, extremely high construction quality requirements, and a long overall construction period. When an emergency occurs, the traditional cast-in-place concrete construction technology cannot meet the ability of rapid construction. Contents of the invention [0004] The purpose of ...
