Abstract
The invention provides a waterproofing treatment manner for an underground position settlement joint in existing building expansion construction. After an expansion polystyrene board (5) and a nine-layer board (6) are coated with a second coiled material layer (1), a first coiled material layer (10) and a lap joint layer (9), the expansion polystyrene board (5) and the nine-layer board (6) are removed, an embedding and filling layer (8) is injected in a cavity, and therefore a novel waterproof structure is formed. The problems of waterproof guard difficulty and leakage of a deformation joint portion in expansion construction are effectively solved.
Description
Technical field
The present invention relates to waterproofing work technical field, particularly a kind of existed building that solves extends the water-proofing treatment mode of position, underground subsiding crack in construction.
Background technology
At present, basement UNICOM road deformation joint waterproof guard is usually taken the form of waterproofing of movement joints structure and processes, its more method is the embedding middle buried water stop in portion in the structure, system carrys out the sedimentation and deformation of commensurate structure by the elasticity of middle buried water stop, thus arriving corresponding waterproof guard requirement.Inventor is by the leakage scenarios analysis of the different waterstop condition of construction of new construction, this positions many, in discovery, buried water stop can not put in place by one-off construction in reality construction process, need to process between segmentation timesharing, cause the waterstop that there is exsertion part to easily cause breakage, and relatively repair more difficult after breakage；Simultaneously because of the differential settlement of structure, the defect of early stage construction, it is easy to cause the breakage at this position, therefore leakage scenarios is more.
For the problems referred to above, need a kind of existed building that solves badly and extend the water-proofing treatment mode of position, underground subsiding crack in construction, basement communication channel deformation joint waterproof guard is improved and set up, the good uncured asphalt paint of creep properties is adopted to carry out waterproof enhancement process, to adapt to the deformation at this position, make up the deficiency that waterstop construction brings, thus solving the leakage problems at this position simultaneously.
Summary of the invention

7) laying expansion polyphenyl plate at described volume Two sheet material layers upper face, expansion polyphenyl plate thickness answers bonding crack wide and the THICKNESS CALCULATION of nine laminates, and expansion polyphenyl plate point is bonded on the waterproof layer of old structure；
8) laying nine laminates on described expansion polyphenyl plate surface, described 9 laminate points are bonded on described expansion polyphenyl plate；
9), after described volume Two sheet material layers is launched, carry out overlap joint process with the new waterproof layer at new bed course position, the new waterproof layer at new bed course position turns to expansion polyphenyl plate and the top of nine laminates；
10) casting concrete, forms concrete floor, reaches after requirement of strength until concrete floor, and precompressed is layered on the new waterproof layer paving at expansion polyphenyl plate and nine laminate tops to new construction sidewall, rear rejects expansion polyphenyl plate and nine laminates；
11) the corresponding encapsulant of pointing, forms pointing layer.
Further, step 1) described hole side is inclined-plane
Further, step 1) width in described hole be 450-550mm, the degree of depth is 450-550mm.
Further, step 3) lap width of described bonding layer and old structure bottom waterproof layer is not less than 500mm, is extended to old structure base slab end face at least 300mm.
Further, step 5) described volume Two sheet material layers length is for being not less than 2m.
Further, step 5) described volume Two sheet material layers employing RWB-801 polymer modified bituminous waterproof sheet material.
Further, step 8) described in use pea gravel concreten to be supported bottom nine laminates, described nine laminate tops can adopt the waterproof layer at newly-built bed course position to turn over bag and process.
Further, step 10) described in pointing layer included uncured rubber asphalt, building asphalt glue, water expandable waterstop successively by inward at both ends.
Further, in step 10) after set up side wall additional waterproof course and waterproof layer, build top concrete, more separately set up film and waterproof coiled material extra play.
