Embodiment 1

[0025] see Figure 1~2 , the precast concrete pavement connection structure based on prestressed series, including pavement connecting plate 1, pavement standard slab 2, reserved installation groove 3, concave-convex groove 4, prestressed tunnel 5, hoisting grouting hole 6, prestressed tendons 7 and prestressed tension end 9; prestressed holes 5 are reserved in the road surface connecting plate 1 and road surface standard plate 2, and four hoisting grouting holes 6 are arranged on the surface of the road surface connecting plate 1, and the The hoisting grouting holes 6 are bidirectionally symmetrically arranged, and the four sides of the road surface standard plate 2 and the road surface connecting plate 1 are arranged with concave-convex grooves 4, which are connected and fixed by concave-convex groove socket connections and prestressed tendons 7 in series, and the prestressed The prestressed fixed end 8 of the prestressed tendon 7 is arranged in the concave-convex groove 4, ...

Embodiment 2

[0033] The installation method of the precast concrete pavement connection structure based on prestressed series, the installation method includes the following steps:

[0034] 1) Complete the construction of the base course of the airport road to ensure that the airport has a certain strength, rigidity and flatness, so as to meet the assembly construction requirements of the subsequent precast concrete pavement connecting plate 1 and pavement standard plate 2;

[0035] 2) Base-level positioning and setting out. According to the overall division of the working surface, each working surface determines the positioning line separately, and places a positioning line at a certain distance to prevent the accumulated error of the plate from being too large;

[0036] 3) For the laying of the precast concrete pavement connection plate 1 and the pavement standard plate 2, the component plates prepared in advance are accurately placed in the positioning position through the hoisting equip...

Abstract

The invention discloses a prefabricated concrete pavement slab connecting structure based on pre-stress series connection and an installation method. The prefabricated concrete pavement slab connecting structure comprises pavement connecting plates, pavement standard plates, reserved installation grooves, concave-convex rabbets, pre-stress hole channels, hoisting grouting holes, pre-stress tendons, pre-stress fixing ends, pre-stress tensioning ends, asphalt and quick-hardening mortar. The invention has the beneficial effects that: according to the concept of splicing small plates into large plates, the splicing is quick, and the integrality is good. The prefabricated concrete pavement slab prestressed tendon connecting structure is simple, the concave-convex tongue-and-groove transmission shear resistance is good, only the connecting plate and the standard plate are in two types, classification is few, the field recognition degree is high, and industrial production and field assembly are facilitated. 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, and the prefabricated concrete pavement slab assembly is suitable for quick assembly construction of airport pavements.

Description

technical field [0001] The invention relates to a prefabricated concrete pavement slab, in particular to a connection structure and installation method of a precast concrete pavement slab based on prestressed series connection, and belongs to the technical field of airport pavement construction. Background technique [0002] Due to the characteristics of fast construction, environmental protection, standardization, and easy intelligence, prefabricated technology has been rapidly developed and widely used in the field of housing construction. Prefabricated concrete pavement construction technology, less wet work on site, fast construction, industrialized production, and guaranteed quality of pavement panels. [0003] The traditional cast-in-place concrete construction technology cannot meet the ability of rapid construction. It is necessary to find and explore more advanced production technologies and methods than the traditional ones, improve the construction technology leve...
