Method for cutting gutter without placing glass observation cover on leveling layer in underground engineering

Abstract

The invention discloses a method for cutting a gutter in underground engineering and canceling a glass observation cover of a leveling layer, and relates to the technical field of underground engineering waterproofing. After being integrally cast and tamped, the underground engineering bottom plate is uneven. And a cement mortar leveling layer is firstly made. When cracks and leakage are generated due to structure settlement, a leveling layer can cover the actual situation of the structure cracks, according to the method, on the surface of a structure bottom plate, the leveling layer is omitted, a water guide groove is cut or pre-buried with a water collecting well as the area center, a plastic drainage plate is laid, a glass observation cover is installed, concrete is poured, and a hollow surface layer is formed, so that the structure cracks can be exposed in the hollow layer; and cracks can be conveniently positioned and maintained. Glass observation covers are dispersedly arranged on the hollow surface layer, an observation point is a double-layer sleeve, an inner sleeve can be taken out, and then a wire of a sight glass is put into the hollow layer, so that the specific position of a structural crack can be conveniently checked in a segmented manner. The inner sleeve and the outer sleeve can be constructed in various ways, the inner sleeve can be taken out, and leaked accumulated water can be pumped out. According to the technical scheme, the surface of the structure is exposed in the hollow layer, the water seepage condition of the structure crack can be timely and conveniently known through the glass observation cover, then the crack is positioned and found, and underground engineering is permanently seepage-free.

Description

Technical Field

[0001] The method of cutting water diversion channels in underground engineering, removing the leveling layer, and placing a glass observation cover falls under the category of building waterproofing, specifically involving the technical field of waterproofing for underground engineering projects. Background Technology

[0002] After the foundation slab of an underground project is poured, unevenness is inevitable, requiring a cement mortar leveling layer. When structural settlement causes cracks and leaks, the leveling layer can obscure the actual condition of the cracks. The technical solution of this invention is to remove the leveling layer on the surface of the foundation slab, with the primary goal of identifying and repairing cracks. Instead, wooden strips are cut or pre-embedded to create drainage channels, allowing seepage water to flow along a fixed path into a collection well. Through a glass observation cover, the structural surface is exposed, allowing the seepage cracks to be detected. Summary of the Invention

[0003] On the surface of the structural base slab, water diversion channels are cut or pre-embedded with wooden strips to eliminate the leveling layer. Plastic drainage boards are laid, followed by concrete pouring to create a hollow surface layer. A glass observation cover is installed within this hollow layer, allowing structural cracks to be exposed for easy location and repair. On the structural base slab, water diversion channels (or pre-embedded wooden strip channels) are cut in sections centered on each water collection well. The glass observation cover is placed at the location of the water diversion channel, allowing for easy monitoring of water seepage from the ground. For the drainage board, a glass observation cover is installed first. An outer plastic pipe is placed and poured into the concrete floor, then leveled. The drainage board at the bottom of the pipe is removed to expose the structural surface. An inner sleeve, smaller than the diameter of the outer sleeve, is then installed. The upper part of the inner sleeve is a glass plate, and the height of the inner sleeve is flush with the floor surface. The gap between the inner and outer sleeves is sealed with adhesive. The inner sleeve can be removed and reinstalled. A glass observation cover is installed on the hollow core layer. The observation cover has a double-layered design, and there are various construction methods between the inner and outer layers. The inner layer can be removed, and the guide wire of the viewing mirror is inserted into the hollow core layer to facilitate segmental inspection of the specific location of structural cracks. The inner layer can also be removed to remove leaking water.

[0004] The beneficial effects of this invention are: it changes the layered construction method in the construction industry, eliminates the leveling layer, exposes the structural surface in the hollow layer, cuts a water diversion channel to allow seepage water to enter the collection well along a fixed route, and then installs a glass observation cover on the water diversion channel, which can promptly and conveniently understand the seepage situation of structural cracks and locate the cracks. It is a technical solution for permanent seepage-free underground engineering. Attached Figure Description
