Abstract
The invention discloses a kind of pipe gallery and its cabinet waterproof constructions, belong to underground pipe gallery technical field.Cabinet in the pipe gallery includes top plate, side wall and bottom plate; two layers of wet-laying waterproof roll, the waterproof roll of resistance to root thorn and pea gravel concreten protective layer are successively equipped on top plate; it is successively equipped with pea gravel concreten protective layer, two layers of wet-laying waterproof roll and concrete cushion on bottom plate, two layers of wet-laying waterproof roll and sintered porous brick setting are successively equipped with outside side wall；Adhesive-layer in wet-laying waterproof roll is mainly made of the ingredient of following parts by weight: modified pitch, plasticizer, antioxidant and fire retardant；Modified pitch is mainly made of raw material from the following weight: pitch, rubber powder, epoxy resin, organic silicon emulsion, polyacrylate, stearic acid, aluminic acid lipoprotein, polyvinyl alcohol, aluminium oxide and calcium carbonate superfine powder.The present invention improves the waterproof effect and service life of pipe gallery cabinet, and reduces the protrusion on ground, improves traffic, has beautified environment.
Description
Technical field
The present invention relates to underground pipe gallery technical fields, and in particular to a kind of pipe gallery and its cabinet waterproof construction.
Background technique
Pipe gallery is exactly the comprehensive corridor of underground urban duct.A tunnel space is built in Urban Underground, it will be electric
Power, communication, the various utilities pipelines such as combustion gas, heat supply, plumbing are integrated in one, and are equipped with special access hole, hoisting port and monitoring
System implements unified planning, Uniting, unified construction and management, is the important infrastructure and " life for ensureing city operations
Line ".
Because pipe gallery is construction of underground structure, to guarantee that each pipeline operates normally in piping lane, piping lane internal box is respectively connect
The waterproof, seepage control of mouth, construction joint etc. is particularly important.However the quality that leakage problem is always puzzlement infrastructure engineering is led to
