A kind of asphalt waterproof coiled material paving equipment and paving method

Abstract

The invention relates to bituminous waterproof sheet material laying equipment and a laying method and belongs to the technical field of waterproof sheet material laying. The equipment comprises a pressing steel roller, a traction device, a melting device and a laying trolley which are sequentially arranged in a laying direction of a waterproof sheet material, wherein the traction device comprisesa scroll and two traction rods; one end of each traction rod is rotationally connected with the scroll; the other ends of the traction rods are rotationally connected with the laying trolley; the melting device comprises a plurality of main blow lamps and a plurality of secondary blow lamps; the ejection direction of the main blow lamp is always a radial direction of the waterproof sheet material; and blow points of the secondary blow lamps are positions close to cross parts of the waterproof sheet material and a base layer surface, and then the base layer surface is preheated before being adhered to the waterproof sheet material. The equipment has the advantages that the waterproof sheet material and the base layer surface can be simultaneously heated, in addition, the waterproof sheet material can be rapidly adhered to the base layer surface, and the adhesion quality of the waterproof sheet material and the base layer surface can be improved.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material paving, in particular to an asphalt waterproof coiled material paving equipment and a paving method. Background technique [0002] The bridge deck waterproof system of highway bridges is extremely important for the protection of the quality of the bridge body. At present, waterproof membranes can effectively solve this problem. At the same time, in the construction of waterproof membranes, how to control the laying of membranes , It is also the top priority to ensure the construction quality of waterproof membranes. [0003] At present, in the construction of waterproof membranes for highways and bridges in China, the pavement of waterproof membranes is mainly carried out manually. When paving, at least three people are required. One person holds a blowtorch to melt the rolls of waterproof membranes, and the other person Observe the melting degree of the waterproof membrane and...

AI Technical Summary

Problems solved by technology

[0007] Since the pavement of the waterproof membrane needs to be combined with the base layer of the road / bridge surface, in the actual construction process, it should be possible to heat the waterproof membrane and the base layer at the same time, otherwise, the hot-melt adhesive will cool down immediately once it touches the base layer , it loses its viscosity before it is fully pasted firmly, thereby reducing the paving quality of the waterproof membrane. In the technical solution disclosed in the above-mentioned invention patent, the blowtorch is fixed on the frame of the trolley (pavement trolley), and only the bottom surface of the waterproof membrane is repaired. Flame-spraying and melting cannot effectively guarantee the paving quality of waterproof membranes;

[0008] Since the blowtorch is fixedly installed on both sides of the trolley frame, the waterproof membrane is heated inside the trolley frame. In the middle, the melting point of the waterproof membrane is easy to produce a certain degree of cooling, which affects the bonding quality of the waterproof membrane and the base layer
