Abstract
The utility model discloses a cable tunnel waterproof structure layer, which comprises a primary support waterproof structure layer and a secondary lining waterproof structure layer. The primary support waterproof structure layer and the secondary lining waterproof structure layer are solidified together, the secondary lining waterproof structure layer is arranged on the inner side of the primary support waterproof structure layer, the primary support waterproof structure layer is composed of a primary support formwork reinforced concrete structure layer, a primary support nonwoven fabric buffer layer, a primary support PVC waterproof board, another primary nonwoven fabric buffer layer and a primary support sprayed reinforced concrete structure layer from outside to inside sequentially, the secondary lining waterproof structure layer is composed of a secondary lining formwork reinforced concrete structure layer, a secondary lining nonwoven fabric buffer layer, a secondary lining PVC waterproof board, a secondary lining nonwoven fabric buffer layer and a secondary lining sprayed reinforced concrete structure layer from outside to inside sequentially. The cable tunnel waterproof structure layer adopting a full enclosed waterproof structure with composite lining interlayer is fine in waterproof effect and free of water leakage after long-term use.
Description
One. technical field: the utility model relates to a kind of waterproof construction layer, particularly relates to a kind of cable tunnel waterproof construction layer.
Two. background technology: along with developing rapidly of urbanization construction, network load increases year by year, the transformer station of urban spraw increases, and the high pressure overhead wire is progressively replaced by cable run, so the construction of cable tunnel is more and more, in recent years, the economic development of Zhengzhou City and construction emphasis are in the Sector East, yet the Sector East geological conditions is poor, and rich groundwater and depth to water are shallow, tunnel full section along the line all is in the phreatic encirclement, and how percolation-proof is the emphasis of construction of tunnel.
Three. the content of utility model:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, intensity is high, implement easily and the cable tunnel waterproof construction layer of good water-proof effect.
The technical solution of the utility model is: a kind of cable tunnel waterproof construction layer, contain just a waterproof construction layer and two lining waterproof construction layers, the two is set in together, and, described two lining waterproof construction layers are positioned at the described inboard of a waterproof construction layer just, a described waterproof construction layer is just built the reinforced concrete structure layer by first formwork from outside to inside successively, just prop up the nonwoven cushion coat, just prop up the PVC splash guard, just a nonwoven cushion coat and a first injection reinforced concrete structure layer constitute, and described two lining waterproof construction layers are built the reinforced concrete structure layer by two lining moulds from outside to inside successively, two lining nonwoven cushion coats, two lining PVC splash guards, two lining nonwoven cushion coats and two linings spray the reinforced concrete structure layer and constitute.
Described formwork just builds the reinforced concrete structure layer, just prop up injection reinforced concrete structure layer, two lining moulds builds reinforced concrete structure layer and two linings and sprays the reinforced concrete structure layers and be made of steel mesh reinforcement and concrete respectively.
The thickness of a described PVC splash guard just and two lining PVC splash guards is 1.2mm, and the thickness of a described nonwoven cushion coat just and two lining nonwoven cushion coats is 1.5mm.
The beneficial effects of the utility model are:
1, the utility model adopts the totally-enclosed waterproof construction of composite lining interlayer, good water-proof effect, and long-term the use do not have infiltration.
2, the utility model concrete structure layer constitutes by concrete and steel mesh reinforcement, and the intensity height adopts the PVC splash guard to cut off the water route fully in addition, and waterproof effect is better.
3, the utility model is reasonable in design, intensity is high, implement easily and good water-proof effect, has good economic benefit after the popularization.
Four. description of drawings:
Fig. 1 is a structural representation of the present utility model.
Five. the specific embodiment:
Embodiment: referring to Fig. 1, among the figure, 1-two linings spray the reinforced concrete structure layer, 2-two lining nonwoven cushion coats, 3-two lining PVC splash guards, 4-two lining moulds are built the reinforced concrete structure layer, 5-just props up injection reinforced concrete structure layer, 6-just props up the nonwoven cushion coat, and 7-just props up the PVC splash guard, and 8-just formwork builds the reinforced concrete structure layer.
Cable tunnel waterproof construction layer contains just a waterproof construction layer and two lining waterproof construction layers, the two is set in together, and, two lining waterproof construction layers are positioned at the described inboard of a waterproof construction layer just, just a waterproof construction layer is built reinforced concrete structure layer 8 by first formwork from outside to inside successively, just prop up nonwoven cushion coat 6, just prop up PVC splash guard 7, just a nonwoven cushion coat 6 and a first injection reinforced concrete structure layer 5 constitute, and two lining waterproof construction layers are built reinforced concrete structure layer 4 by two lining moulds from outside to inside successively, two lining nonwoven cushion coats 2, two lining PVC splash guards 3, two lining nonwoven cushion coats 2 and two linings spray reinforced concrete structure layer 1 and constitute.
Just formwork is built reinforced concrete structure layer 8, is just propped up injection reinforced concrete structure layer 5, two lining moulds and build reinforced concrete structure layer 4 and two linings and spray reinforced concrete structure layers 1 and be made of steel mesh reinforcement and concrete respectively.Just the thickness of a PVC splash guard 7 and two lining PVC splash guards 3 is 1.2mm, and the thickness that just props up nonwoven cushion coat 6 and two lining nonwoven cushion coats 2 is 1.5mm.
Claims (3)
