Portable high-efficient low-cost road surface joint-cutting device for public road bridge roof beam construction

Technical Field

The utility model belongs to the technical field of the cement road surface cutting construction, a joint-cutting device is related to, especially a road surface joint-cutting device is used in public road bridge roof beam construction of portable high efficiency low-cost.

Background

With the rapid development of road traffic construction, when a road serving as a traffic infrastructure is put into operation, the temperature stress generated by the temperature rise and expansion of the road surface due to overhigh external temperature can cause the stress concentration phenomenon, and the buckling and fracturing of the road surface or the concrete crushing can be caused under the action of driving load; in a low-temperature environment, the pavement is contracted and cracked due to low temperature, so that pavement expansion joints are required to be arranged. Expansion joints in roads are typically cut by road cutting devices.

The joint cut by the concrete pavement is called 'expansion joint'. In the concrete setting and hardening process, a large amount of heat is released when cement is hydrated, so that the temperature of the concrete is increased; most of the cement hydration reactions are over and the concrete temperature begins to drop. In the cooling process, the concrete is already solidified and hardened, the concrete is cracked due to shrinkage caused by cooling, the directions of the cracks are random, and the pavement quality and the service life are seriously influenced.

Therefore, the contraction joints are cut at intervals of 4-6 m generally 8-12 hours after concrete pouring (before the temperature of the concrete pavement begins to reduce), and the cutting depth is about one third of the thickness of the pavement slab, so that the contraction cracks of the concrete can be induced to be generated along the cutting joints, and random cracks are prevented. Then, asphalt or sealant is poured into the pavement contraction joint for sealing, so that rainwater, snow and water are prevented from entering the roadbed.

The main method for joint cutting treatment of the traditional pavement is to manually hold the joint cutting device for cutting, so that the precision is low, the labor is greatly consumed, and the safety is low. Therefore, automatic joint cutting devices appear in the market, but the automatic joint cutting devices need a plurality of driving sources, and are large in energy consumption, heavy in equipment and large in manpower consumption.

After the joint cutting is finished, joint filling materials are mostly backfilled to seal the layer, the joint needs to be cleaned, and if the joint filling materials are asphalt materials, the joint needs to be dried, the conventional device does not have the functions, so that the construction efficiency is seriously influenced.

Through retrieval, for example, chinese patent document discloses a concrete pavement joint cutting device [ application number: cn201711175837. x; publication No.: CN 107905080A). The joint cutting device comprises a bottom plate and the like; the pushing hands are installed on the left side of the top of the bottom plate, the wheels are installed on the left side of the bottom plate in a symmetrical mode, the cylinder is installed on the upper portion of the left side of the front side of the bottom plate, the cylinder is vertically arranged, the transverse plate is installed on the telescopic rod of the cylinder, the guide device is arranged on the left side of the bottom of the transverse plate, and the guide device is located on the right side of the left side of the wheels. The joint cutting device can perform joint cutting and also can remove residual fragments, and the dust falling device can spray water to remove smoke dust; but can not accurate control joint-cutting degree of depth, joint-cutting inefficiency, do not possess and clean stoving function, can not satisfy and backfill joint-filling material fast and carry out the seal.
