Cement pavement slab staggering treatment structure and construction method

Abstract

The invention relates to a cement pavement slab staggering treatment structure and a construction method. The slab staggering treatment structure comprises a base layer and an old surface layer; the slab staggering treatment structure further comprises a repairing layer, a slab staggering connecting part, a leveling layer and a new surface layer. The old surface layer comprises an in-situ plate and a sinking plate; a pulling device is arranged in the repairing layer and the slab staggering connecting part; anti-upheaval devices are arranged on the in-situ plate and the leveling layer. The slab staggering positions of the old surface layer are connected into a whole, so that the problem of reflection to the new surface layer from a penetrating crack is effectively solved; an anti-upheaval device is arranged to effectively relieve the generation of upheaval diseases of a new surface layer; while the original cement concrete surface layer is treated, the void of the base layer below the staggered slab junction gap is treated, so that the generation of the pavement structure crack is delayed.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a cement pavement stagger treatment structure and a construction method. Background technique [0002] In order to improve driving comfort and reduce noise, it has become the key task of road engineering construction to transform cement concrete pavement into asphalt concrete pavement. Cement concrete pavement surface will have diseases after long-term use, such as: wrong platform and so on. The staggering of cement concrete pavement refers to the phenomenon of relative vertical displacement between adjacent slabs at the joints or cracks of the pavement. The wrong platform is mainly caused by the repeated action of the vehicle load after the base layer is empty. The staggered platform phenomenon will not only affect the flatness of the newly paved asphalt concrete pavement, but also form cracks on the newly paved asphalt concrete pavement after completion, ...

AI Technical Summary

Problems solved by technology

However, under the action of moisture erosion and vehicle load, the pouring material is easy to fall off or be damaged from the concrete panel, thus losing the effect of repairing and caulking

[0005] 3. The asphalt concrete surface is paved on the cement concrete pavement, and the bonding and compounding effect of the two is poor, and it is prone to diseases such as wrapping under the action of vehicle loads

At present, the measures to enhance the composite effect are mainly to spread sticky oil and roughening treatment on the cement concrete pavement, but the effect of spreading sticky oil and roughening treatment on the bonding effect is not obvious

[0006] 4. At present, most of the treatment for adding asphalt concrete surface layer is for the concrete surface layer, and after long-term use of cement concrete pavement, especially under the gap between the staggered platforms, due to rainwater erosion or uneven settlement of the foundation The problems such as the emptying of the grass-roots level have been particularly obvious
