Description

A kind of waterproof construction of pipe gallery outer wall
Technical field
The utility model belongs to Urban Underground pipe gallery technical field, in particular a kind of waterproof 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 made to scrap, jeopardize urban pipeline engineering, city is made to paralyse, 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.
Invention content
The purpose of this utility model is to provide a kind of waterproof construction of pipe gallery outer wall, there is leakage to solve existing piping lane The technical issues of water seeps water.
Technical solution is as follows used by the utility model realizes above-mentioned purpose:A kind of waterproof knot of pipe gallery outer wall Structure, it is characterised in that:Waterproof construction includes three waterproof roofing structure, side wall waterproof construction and waterproof slab structure composition portions Point;Waterproof roofing structure is followed successively by self waterproof concrete structure layer, uncured rubber asphalt waterproof coating layer, two-sided from inside to outside Self-adhesion root-resistant puncturing type waterproof roll layer, dry felt-laying separation layer and pea gravel concreten protective layer;Side wall waterproof construction by it is interior to It is followed successively by self waterproof concrete structure layer, uncured rubber asphalt waterproof coating layer, double-sided self-adhesive waterproof coiled materials layer, polyphenyl second outside Alkene plastic foamboard layer and flyash solid brick protective layer;Waterproof slab structure is followed successively by from outside to inside:Pea gravel concreten is protected Layer, double-sided self-adhesive waterproof coiled materials layer, pea gravel concreten sloping layer, self waterproof concrete structure layer and indoor pea gravel concreten look for slope 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 Aqueous can be that code requirement answers option.
It plants top panel area and 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 enhance the repair ability of waterproof roll, double-sided self-adhesive root-resistant puncturing type waterproof roll layer and self waterproofing are mixed It is coated with uncured rubber asphalt waterproof coating layer between Xtah Crude Clay structure layer, creep properties and the flexibility 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 utility model, the mode for taking inner waterproofing to be combined with outer waterproof have organized multiple tracks anti- Water defence line, and specially treated has been done to special joint, more meet the demand for development of pipe gallery.The utility model forms city The unified water-proof system of pipe gallery has the advantages that compared with traditional single waterproof roll:It solves Pipe gallery punches more, the more caused infiltrations in branch corridor, seepy question, especially in level of ground water area higher, ensure that synthesis The durability and safety that piping lane uses.Multi layer waterproof defence line has been organized, has been set up defenses in depth, has been failed together, also lower one of defence line, And it can repair in time, more meet the century-old design requirement of pipe gallery.The particularity of node is considered, different nodes is adopted With different designs.Water-proof system is avoided to be broken through by the destruction of a certain node.
