Description
Technical field
The invention belongs to Urban Underground pipe gallery technical field, is in particular a kind of waterproof knot of pipe gallery outer wall
Structure.
Background technology
With the rapid development of city integrated piping lane in recent years, more and more pipe galleries built up expose difference
The seepy question of degree.Once underground pipe gallery leak, will directly affect the operation and maintenance of piping lane, if leak is serious,
Can even pipe gallery be scrapped, jeopardize urban pipeline engineering, city is paralysed, consequence is very serious.So.In setting for piping lane
The meter stage just needs consideration waterproof problem comprehensive in advance, and the complete design task that the construction stage guarantees both quality and quantity, can
Reduce the seepy question for even avoiding pipe gallery.
The content of the invention
The object of the present invention is to provide a kind of waterproof construction of pipe gallery outer wall, there are leak to solve existing piping lane to ooze
The technical problem of water.
Technical solution is as follows used by the present invention realizes above-mentioned purpose：A kind of waterproof construction of pipe gallery outer wall, its
It is characterized in that：Waterproof construction includes three waterproof roofing structure, side wall waterproof construction and waterproof slab structure parts；Top plate
It is resistance to that waterproof construction is followed successively by self waterproof concrete structure layer, uncured rubber asphalt waterproof coating layer, double-sided self-adhesive from inside to outside
Root puncture type waterproof roll layer, dry felt-laying separation layer and pea gravel concreten protective layer；Side wall waterproof construction is from inside to outside successively
For self waterproof concrete structure layer, uncured rubber asphalt waterproof coating layer, double-sided self-adhesive waterproof coiled materials layer, polystyrene foam
Plastic plies and flyash solid brick protective layer；Waterproof slab structure is followed successively by from outside to inside：It is pea gravel concreten protective layer, two-sided
Adhesive waterproof coil layer, pea gravel concreten sloping layer, self waterproof concrete structure layer and indoor pea gravel concreten sloping layer.
Piping lane main body（Waterproof concrete structure layer）Using the water-proof concrete not less than C30, seepage-resistant grade is not less than P6.
Wherein, waterproof concrete structure layer is that concrete shrinkage deformation cracks in order to prevent, improves concrete structure density and prevents certainly
It is water-based to answer option for code requirement.
Plantation top panel area uses double-sided self-adhesive root-resistant puncturing type waterproof roll layer；It can prevent the root system of plant above top plate
Puncture waterproof roll.To strengthen the repair ability of waterproof roll, double-sided self-adhesive root-resistant puncturing type waterproof roll layer and self waterproofing mix
Uncured rubber asphalt waterproof coating layer is coated between Xtah Crude Clay structure layer, creep properties and the pliability of water-proof system can be increased,
It is the adhesive of waterproof roll and concrete, option is answered for code requirement.
To destroy water-proof system, the concrete cover and bubble that top plate uses when preventing when being backfilling and compacted or excavating later
Foam plastic plate, the protection of flyash solid brick and plastic foamboard that side wall waterproof construction uses play guarantor to piping lane water-proof system
Shield acts on.
Technical solution provided by the invention, the mode for taking inner waterproofing to be combined with outer waterproof, has organized multi layer waterproof to prevent
Line, and specially treated has been done to special joint, more meet the demand for development of pipe gallery.The present invention forms city integrated piping lane
Unified water-proof system, compared with traditional single waterproof roll, have the advantages that：Solves pipe gallery
Punch more, the more caused infiltrations in branch corridor, seepy question, especially in level of ground water area higher, ensure that pipe gallery uses
Durability and security.Organized multi layer waterproof defence line, set up defenses in depth, together fail, also lower one of defence line, and energy and
When repair, more meet the century-old design requirement of pipe gallery.The particularity of node is considered, different nodes employs difference
Design.Water-proof system is avoided to be broken through by the destruction of a certain node.
