A construction method of rubber-plastic blended waterproof membrane

Abstract

The invention relates to a rubber and plastic co-mixed waterproof roll construction method. The rubber and plastic co-mixed waterproof roll construction method mainly comprises such steps as base layer treatment, size determination, end placement and positioning, gluing and bonding, compaction exhausting and end collecting treatment; leveling equipment comprises a mounting chassis; the mounting chassis consists of a longitudinal exhaust bracket and a transverse exhaust bracket; a longitudinal exhaust branched chain is arranged on the longitudinal exhaust bracket; and a transverse exhaust branched chain is arranged on the transverse exhaust bracket. The rubber and plastic co-mixed waterproof roll construction method can solve the following difficulties in the construction process of traditional rubber and plastic co-mixed waterproof rolls: (a) paved waterproof rolls need to be manually compacted; and during paving of the rolls, air between the paved rolls and base layers is expelled; and (b) the manual exhaust efficiency of the waterproof rolls during paving is low; the viscosity between the rolls and the base layers after bonding is higher; the air between the rolls and the base layers cannot be totally removed through simple expelling; and the construction quality of the rubber and plastic co-mixed waterproof rolls is influenced.

[0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls. Waterproof membrane It is generally composed of flexible materials such as rubber and plastic. At the same time, waterproof membranes made of rubber-plastic blends are more common. In the laying of waterproof membranes, the cold bonding method is usually used. The cold bonding method mainly includes the following steps: Treatment, size determination, head positioning, glue application, compaction and exhaust, and end closure treatment, etc., among which compaction and exhaust play a vital role in the construction quality of waterproof membranes. Incomplete gas discharge will lead to adverse effects such as bulging and wrinkling of the waterproof membrane in high temperature weather, thereby reducing the service life of the waterproof layer

[0003] However, there are the following problems in the construction process of the rubber-plastic blended waterproofing membrane: a. It is necessary to manually compact the waterproofing membrane after laying. The gas is pressurized, which cannot be operated by a single person, and requires the cooperation of the staff. The operation is complicated and time-consuming. b. The efficiency of exhausting the waterproof membrane during the laying operation is low, and the laminated membrane and the base layer The stickiness between them is relatively large, and manual exhaust construction consumes a lot of physical strength. Simple pressure cannot completely remove the air between the membrane and the base layer, which affects the construction quality of the rubber-plastic blended waterproof membrane.
