Embodiment

[0073] First arrange the longitudinal steel bars 3 and the horizontal steel bars 4 vertically and tie them securely, then put the whole of the longitudinal steel bars 3 and the horizontal steel bars 4 into the mold, and fix the fixing parts 5 at the designated positions, then pour concrete and wait for cooling to form Concrete block 2, and then install the stopper 6 in the interior of the fixture 5 by means of threaded connection, and lift up the mold by hooking the hook 7 above the stopper 6; it is made by formwork pouring cement concrete layer 101, and make the upper surface of the cement concrete layer 101 have a concave-convex structure, place the concrete block 2 on the inside of the cement concrete layer 101, then remove the stopper 6, and fix it by pouring concrete. The inside of part 5 and the notch 105 are filled, and the reliability of the connection between the concrete block 2 and the base 1 is enhanced. Finally, the sealing layer 8 is laid on the upper surface of t...

Abstract

The invention discloses a roadbed construction method of a highway reinforced concrete pavement. The roadbed construction method comprises the following steps: 1, prefabricating reinforced concrete pavement components; 2, excavating and laying a base; 3, assembling the reinforced concrete pavement component and the base; 4, laying a sealing layer and a maintenance layer, wherein the reinforced concrete pavement component in the step 1 comprises a concrete block, a longitudinal steel bar, a transverse steel bar, a fixing piece, a limiting piece and a lifting hook, the longitudinal steel bar andthe transverse steel bar are embedded in the concrete block, and the longitudinal steel bar and the transverse steel bar are connected in a bundling mode; fixed pieces are embedded in the left end and the right end in the concrete block correspondingly, the fixed pieces and the limiting pieces are arranged in a one-to-one correspondence mode, and the limiting pieces are welded to the lifting hooks. According to the roadbed construction method of the highway reinforced concrete pavement, the roadbed formed after construction is long in service life, large-area breakage is prevented, and partial repair of the pavement is facilitated.

Description

technical field [0001] The invention relates to the related technical field of highway reinforced concrete pavement, in particular to a subgrade construction method of highway reinforced concrete pavement. Background technique [0002] In order to meet the requirements of long-term use of roads and not easy to break, roads with reinforced concrete pavements are widely promoted, and according to different road needs, the subgrade construction methods of reinforced concrete pavements are also different, but the existing subgrade construction methods of reinforced concrete pavements There are still some deficiencies, such as: [0003] The authorized announcement number is CN102127889B "Subgrade Construction Method for Highway Reinforced Concrete Pavement". This invention discloses a roadbed construction method for highway reinforced concrete pavement. The soil is leveled, rolled and compacted; then paved with steel slag in two layers, each layer with a thickness of 95-105 mm; ...
