Pressure-relief-prevention combined product replacing concrete leveling layer

Abstract

The utility model discloses a pressure-preventing and pressure-discharging combined product replacing a concrete leveling layer, and relates to the field of waterproof, drainage and pressure-resisting structures of building underground engineering top plates and roofs. According to an existing method, a concrete protection layer is firstly made on a waterproof layer of a top plate and a roof to serve as a protection layer of the waterproof layer, due to the fact that a water channeling layer can be formed between concrete and the waterproof layer, only the anti-compression protection function is achieved, the concrete protection layer needs to wait for the curing period, and self-adhesion waterproof coiled materials are laid on the original waterproof layer of the top plate and the roof to cause the self-adhesion waterproof coiled materials to be damaged. The self-adhesive waterproof coiled material is in flush joint with the drainage plate, two or four rows of drainage plate strips are arranged at joints, and the drainage plate strips are buckled together through mucilage glue to form a combined whole product. An original concrete protection layer can be replaced, no water channeling layer exists on an original waterproof layer, and the standard requirement for pressure resistance is met.

Description

Technical Field

[0001] The invention discloses a pressure-resistant and pressure-relief combined product for replacing a concrete leveling layer, and relates to the field of waterproofing, drainage and pressure-resistant structures of top plates and roofs of underground construction projects. Background Art

[0002] The standard practice in the existing technology is to first make a 50-70mm concrete protective layer on the top plate and the roof waterproof layer as a protective layer for the waterproof layer, and then make drainage boards and green covering soil, etc. Since a water seepage layer will be formed between the concrete and the waterproof layer, it only plays a compressive protection role, and the concrete protective layer has to wait for a maintenance period. For this reason, this product can not only meet the compressive protection function, but also shorten the construction period and ensure that there is no water seepage layer on the waterproof layer. Summary of the invention

[0003] On the original waterproof layer of the top plate and roof, the self-adhesive waterproofing membrane is laid, and the drainage board is flat-jointed on the self-adhesive waterproofing membrane. The joints have two or four rows of drainage board strips, which are buckled together with adhesive to form a combined integral product. It can replace the original concrete protective layer, and can make the original waterproof layer without water leakage layer, achieve better waterproof quality, and the drainage board meets the standard requirements of compression resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0004] Figure 1 This is a structural cross-section diagram. DETAILED DESCRIPTION

[0005] Figure 1 It is a structural cross-section diagram. The top of the structural plate 1 is the original waterproof layer 2, and then this product. The drainage board 4 on the self-adhesive membrane 3 is flat-jointed, and there is glue 5 at the joints. Two or four rows of drainage strips 6 are buckled on. 3, 4, 5, and 6 are this product, and then the geotextile 7 is laid and other construction methods 8 are used.

Claims

1. A pressure relief combined product that replaces the concrete leveling layer, characterized in that The self-adhesive waterproof membrane is flat-jointed with drainage boards, and the joints have two or four rows of drainage strips, which are fastened together with glue to form a combined integral product.
