Joint drainage type cement concrete road structure and construction method thereof

Abstract

The invention discloses a joint drainage type cement concrete road structure. The cement concrete road structure is formed by splicing a plurality of cement concrete slabs; vertically and horizontally staggered joints are retained among all the cement concrete slabs; and a water collecting aluminum plate which is similar to a groove shape and leads to an edge drainage system is arranged at the bottom of the cement concrete road structure and below all the joints. A construction method of the road structure comprises the following steps of: designing concrete positions of the joints at the construction planning road section; then placing and fixing the water collecting aluminum plate on a road base layer in the corresponding position; constructing on the road base layer paved with the water collecting aluminum plate according to the conventional process to obtain a road structure body; then sawing at the joint positions; and finally, constructing the edge drainage system. The cement concrete road structure of the invention has the advantages of simple structure, convenience of construction, high durability, and the like.

Description

technical field [0001] The invention relates to a concrete pavement and a construction method thereof, in particular to a drainable concrete pavement and a construction method thereof. Background technique [0002] In order to avoid irregular cracking of the poured cement concrete pavement due to drying and temperature shrinkage, the new cement concrete pavement must be divided into regular plates with a certain size by longitudinal and transverse joints. The existence of joints makes it easy for rain and snow water to penetrate into the interior of the pavement structure through the joints, softening the pavement material, and under the repeated action of the traffic load, it will generate slurry, which will make the bottom of the slab hollow, and then cause the slab to break and accelerate the destruction of the pavement structure . Slurry, void at the bottom of the slab, broken slab, etc. are the most common diseases in cement concrete pavement. [0003] For the problem...

AI Technical Summary

Problems solved by technology

[0003] For the problem of joints that are prone to water seepage, sealing materials are usually used to seal the joints to prevent water from seeping down through the joints. Under the combined effects of moisture, humidity and driving load, repeated complex effects such as stretching, compression, shearing, etc., are prone to damage such as extrusion, debonding, aging, falling off, etc., and soon lose the waterproof effect of sealing seams

The current various sealing materials (including commonly used asphalt, and various special sealing materials specially developed) have the problems of poor durability and unsatisfactory use effect

If it cannot be maintained and replaced in time, rain and snow will seep into the joints, which will accelerate the destruction of the pavement structure, reduce the performance and service life of the pavement, and increase the maintenance workload.

Since the treatment of cement concrete pavement diseases such as grouting, hollowing out, and broken boards is relatively complicated and takes a long time, once damage occurs, it will have a great impact on traffic
