Material.
Currently, in underground engineering, general waterproof in the following way：It utilizes（Coiled material）It is fixed on concrete surface, and it is mixed
Solidifying soil, which combines, plays waterproof action, but it is mainly manifested in there are the defect of universality energy：
1, waterproof roll material itself cannot be closely connected with concrete, and the protrusion of impact or concrete surface occurs when installing
Situations such as object, easily punctures splash guard, leads to leak；
2, the joint portion between plate and plate is the weak link of piping lane, occurs crack if careless slightly and can lead to entire waterproof body
System's failure；
3, concrete wall face is susceptible to concave-convex position or even larger cavity, squeezes and week can make waterproof along deformation
Especially in conjunction with position rupture failure easily occurs for plate stretching.

Waterproof slab node, adopt the following technical scheme that：
A kind of waterproof slab node for underground pipe gallery, the underground pipe gallery include by bottom plate, both sides side wall and top
Nacelle that is that plate surrounds and extending longitudinally, the construction joint between bottom plate and both sides side wall are located on horizontal plane, the bottom
Plate waterproofing node includes the concrete cover, base plate waterproofing and bed course being arranged on bottom plate bottom edge, and is arranged outside side wall
Side wall waterproof layer, wherein waterproof slab is placed between concrete cover and bed course, and the base plate waterproofing is along bottom plate side
Edge direction is flipped up to the construction joint, and lower brick wall protection is provided on the outside of the base plate waterproofing of the side edge of the bottom plate
Layer, it is provided with brick wall protective layer on the outside of the side wall waterproof layer.
Further, the base plate waterproofing includes several coiled materials of cross-level compacting, long side direction and short side direction
The equal cross-lapping in end and side of adjacent web be laid with.
Preferably, the width of the short side overlapping regions on short side direction is more than or equal to 10cm.
Preferably, the distance that spreads out of the coiled material is more than or equal to 30cm.
Preferably, be staggered 50cm or more between the adjacent short sides overlapping regions of the adjacent web on short side direction.
Preferably, the coiled material includes stacked self-adhering polymer waterproof layer and macromolecule pre-installed and inverted adhered waterproof layer, wherein
Self-adhering polymer waterproof layer is contacted with concrete cover, macromolecule pre-installed and inverted adhered waterproof layer and layer contacts.
Preferably, it is provided with waterproof reinforced layer on the outside of the base plate waterproofing at the end angle of the bottom plate.
Preferably, it is provided with side wall waterproof reinforced layer on the outside of the side wall waterproof layer at the construction joint.
By above technical scheme it is found that the utility model fundamentally solves in underground engineering the only not anti-structure of anti-bed course
The common fault of layer, and the pre-installed and inverted adhered technology relative to coiled material is improved, and has accomplished the skin-type waterproof without overlapping the slot, it is real
Existing integral seamless connection, the package structure layer as skin can preferably protect structure sheaf, it is anti-to have reached real skin-type
Water, after preventing bed course valve pit subsidence, drawing crack waterproof layer reduces the possibility of string water leak to extend the waterproof time limit.
Description of the drawings
Fig. 1 is the lateral rearview of underground pipe gallery, shows underground pipe gallery waterproof construction；
Fig. 2 is the structural schematic diagram of the utility model bottom plate waterproofing node；
Fig. 3 is the floor map of coiled material lapping in the utility model.
Specific implementation mode
A kind of preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the underground pipe gallery 50 include surrounded by bottom plate 51, both sides side wall 52 and top plate 53 and along vertical
