Abstract
The utility model discloses a concrete base plate watertightness structure that has underground continuous wall, characterized by underground continuous wall and concrete floor handing -over position middle part underground continuous wall evagination, the notch cuttype is made to the evagination shape, adopt the water -swelling rubber sealing rod to seal at outside evagination structure both ends, the inflation rubber sealing rod outside is applied paint polyurethane with a brush and is filmed, set up waterproof mortar layer below the concrete floor, set up the pea gravel concreten bed course below the waterproof mortar layer, pea gravel concreten intensity is C15, the concrete intensity of concrete floor is C30, set up the mortar protective layer above the concrete floor, the mortar strength that the mortar protective layer adopted is M7.5, underground continuous wall sets up the malthoid as waterproof additional layer with the reentrant corner of concrete floor handing -over. The utility model discloses water -proof effects is good.
Description
Technical field
This utility model relates to a kind of concrete floor water proof structure having diaphram wall, it is adaptable to waterproof neck
Territory.
Background technology
Underground parking or basement construction are because it is long in time limit, it is big to put into, materials are many, subsurface picture is complicated many
Become, construction organization difficulty is big.Therefore, basement engineering quality problems continue to bring out out, at the bottom of basement
The water proof anti-seepage of plate becomes the difficult miscellaneous diseases perplexing whole building circle, especially has the concrete of diaphram wall
It is the difficult problem run in engineering practice that waterproof slab processes.
Utility model content
This utility model solves the technical problem that and is to provide a kind of waterproof structure of concrete floor having diaphram wall
Make, the problem solving concrete floor infiltration.
This utility model includes polyurethane coating film, water-swelling rubber water bar, pea gravel concreten bed course, prevents
Water screed, malthoid, mortar cover, diaphram wall and concrete floor join underground in the middle part of position and connect
Continuous wall evagination, convex shape is made notch cuttype, is used hydro-expansive rubber only at the outer male structure two ends of outermost
Water bar is closed, and brushing polyurethane coating film outside expanded rubber sealing rod, middle part diaphram wall evagination is also arranged
Waterproof measure has blocked infiltration path the most well, and concrete floor is provided below waterproof mortar course, waterproof
Screed thickness is 15～25mm, and waterproof mortar course is provided below pea gravel concreten bed course, and pea gravel concreten is strong
Degree is C15, and the concrete strength of concrete floor is C30, and concrete floor is arranged above with mortar cover,
The mortar strength that mortar cover is used is M7.5, and the inner corner trim that diaphram wall joins with concrete floor sets
Put malthoid as additional waterproof course.
This utility model good water-proof effect.
