Problems solved by technology

Because the indoor concrete floor and wall decoration layer of the underground project covers the structural cracks, the future seepage position is inconsistent with the crack position, and it is difficult to maintain. Therefore, my country's "Regulations on the Quality Management of Construction Engineering" has

Example Embodiment

[0015] in figure 1 Among them, the structural outer wall facing the room is a bare structural wall (1), and the partition hollow layer (2) and the masonry partition wall (3) are the hollow structural layer of the wall.

[0016] figure 2 , The structural exterior wall facing the interior is the exposed structural wall (1), fix the plastic board with fulcrum on the wall, form a hollow layer 2 in the middle, and then do cement mortar painting or fix the prefabricated cement pressure board to become the hollow structure layer (3).

[0017] image 3 On the bare structural ground (4), plastic plates with fulcrums of empty cups are filled and concrete is poured to form a hollow structure layer (5), and the middle of the fulcrums is the hollow layer (2).

[0018] Figure 4 , Install an openable skirting board (6) on the concrete floor at the bottom of the wall, which is the opening cover for the hollow layer of the wall, which can be closed with silica gel. When you need to observe, open th...

Abstract

The invention provides a permanent leakage-free maintenance system built in underground engineering and relates to the field of water proofing and structural safety of the underground engineering. At present, the leakage rate of the underground engineering reaches 80%, structural cracks causes corrosion of steel bars, and a building structure is damged. An underground space is continuously expanded, subway tunnels are criss-cross, and the structural safety is influenced by the maintenance problem of the underground engineering. Due to the fact that indoor concrete floors and wall face decoration layers of the underground engineering press the structural cracks, maintenance is difficult to perform. The indoor surface of an underground structure is exposed and is covered by a hollow structural layer, and an opening cover plate is arranged on a hollow face layer. A water storage trough for independently collecting seeped water of all structures is arranged in a water collecting well, then a water level observation instrument for recording the water level of the water storage trough is arranged in the well, a structural safety digitalized system is built, an electronic instrument is used for observing the cracks in the structural faces, the maintenance is facilitated, centennial safety of the underground structure is guaranteed, and the permanent leakage-free maintenance system is a permanent leakage-free project.

Description

technical field [0001] Establishing a permanent non-leakage maintenance system in underground engineering is maintenance for the safety of underground building structures, and relates to the technical fields of underground engineering waterproofing and structural safety. Background technique [0002] The service life of the underground engineering structure is 70 to 100 years, so the structural quality should have the construction quality during construction and the maintenance quality during long-term use. Because the indoor concrete floor and wall decoration layer of the underground project covers the structural cracks, the future seepage position is inconsistent with the crack position, and it is difficult to maintain. Therefore, my country's "Regulations on the Quality Management of Construction Engineering" has no warranty requirements for the waterproof quality of underground projects. People's Daily reported on May 30, 2012, "my country's building leakage rate reaches ...
