Problems solved by technology

Cast-in-place concrete temporary pavement concrete takes a long time to maintain, and it will generate noise, dust and construction waste during demolition, polluting the environment
The gravel or steel slag road surface is not easy to clean, the dry road surface has a lot of dust, and it takes a lot of labor and water to sprinkle dust to reduce the dust. The road surface is easily damaged and has poor flatness. Frequent repairs affect the use of the road and are not conducive to civilized construction.

Embodiment Construction

[0013] From Figure 1 ~ Figure 4 It can be seen from the figure that: a reinforced concrete prefabricated road slab and its installation and construction method are characterized in that the reinforced concrete prefabricated road slab is made into a tongue-and-groove slab ( figure 1 ), with a plate thickness of 220mm, a male groove 1 is set in the middle part of the left plate thickness, and a female groove 2 is set in the middle part of the right plate thickness. The width of the male groove is smaller than the width of the female groove. Two full-length angle steels 3 are provided for protection at the joints of the groove and the groove and groove, and a steel pull ring 4 is respectively installed in the middle part of the plate thickness at the upper and lower 1 / 4 spans of the length of the groove on the left side. Grooves 5 are provided in the middle of the plate thickness corresponding to the two steel bar pull rings 4, and a steel sleeve 6 perpendicular to the plate sur...

Abstract

The invention discloses a reinforced concrete prefabricated road slab and an installation and construction method thereof. The reinforced concrete prefabricated road slab is made into a groove and tongue batten, a groove and tongue male groove is arranged in the left middle part of the thickness of the batten, a groove and tongue female groove is arranged in the right middle part of the thickness of the batten, the connector points of the groove and tongue male groove and the groove and tongue female groove are respectively provided with two full-length steel angles for protection, in addition, a rebar pull ring is respectively arranged at the middle parts of the thickness at the upper 1 / 4 span point and the lower 1 / 4 span point of the length of the left groove and tongue male groove, grooves are respectively arranged in the middle parts of the thickness at the right groove and tongue female groove corresponding to the two rebar pull rings, and the middle parts of the grooves are respectively embedded with a steel sleeve perpendicular to the slab surface. The road slab is suitable for industrial production, on-site wet operation is reduced, the engineering cost is reduced, the construction speed is high, the integrity of the road is good, and the reinforced concrete prefabricated road slab has good self-cleaning performance, is easy to clean, and is low-carbon and environment-friendly.

Description

technical field [0001] The invention belongs to building construction technology, in particular to a reinforced concrete prefabricated road slab and its installation and construction technology. Background technique [0002] Temporary roads for existing construction often use cast-in-place concrete pavement, gravel or steel slag pavement. The cast-in-place concrete temporary pavement takes a long time to maintain, and it will generate noise, dust and construction waste during demolition, polluting the environment. The gravel or steel slag pavement is not easy to clean, the dry pavement raises a lot of dust, and it is labor-intensive and water-intensive to spray the dust to reduce the dust. Contents of the invention [0003] The purpose of the present invention is to provide a reinforced concrete prefabricated road slab and its installation and construction method. The slab is suitable for industrialized production, reduces on-site wet work, can be used for turnover in the...
