Abstract
The invention relates to the field of tunnel, in particular to a tunnel wholly-covering waterproof edge seal waterproof device, namely a tunnel wall wholly-covering waterproof layer end seal device. The device comprises a steel structure of a connecting channel between the tunnels and is characterized in that the waterproof device comprises a upper-pressuring steel bar, a pushing steel bar and edges of a waterproof layer; the pushing steel bar is fixed on the steel structure; the waterproof edge is arranged in the plane position between the upper-pressuring steel bar and the pushing steel bar; and the upper-pressuring steel bar and the pushing steel bar are connected and fixed by a bolt. The device has the advantages that a waterproof layer terminal connected by the waterproof device has very good seal performance and the construction is convenient, economical and practical. The waterproof layer terminal can bear 0.9 MPa of water pressure and has relatively high waterproof safety factor reservation.
Description
Technical field
The present invention relates to tunnel-like, be specifically related to a kind of sealing water-tight device for interface channel waterproofing course between the tunnel, be i.e. the end-enclosed device of full-packaging waterproof layer on a kind of tunnel wall.
Background technology
Interface channel between shield tunnel, the general bag waterproof homework entirely that adopts in Mining Method tunnel, the main material of full-packaging waterproof layer is ECB, PVC, its final end-enclosed is very important.
Briefly introduce the tunnel water proofing technology of domestic common employing below by Waterproof engineering of submarine tunnel in Xiamen Xiangan.The seabed tunnel waterproofing mainly comprises: the thin section waterproof of preliminary bracing waterproof, splash guard waterproof, two lining concrete self-waterproofs and constuction joint, settlement joint.Splash guard waterproof construction process is at first nonwoven to be fixed in preliminary bracing with cement nail and plastic washer, then use the pressure welding device with the splash guard heat seal on plastic washer.The splash guard lap length is 10～12cm by standard and designing requirement, uses the automatic creeping heat-sealing machine to carry out the indirect seam welding of plate, is welded into two weld seams, every wide 1cm of weld seam, and there is the wide cavity of 2cm the centre, is used for the leakproofness that inflation checks weld seam.
Waterproof roll fabric width 2.1M, need the polylith splash guard to connect therefore consist of waterproofing course, the problems such as easy rosin joint or failure welding during welding, also there is the inadequate defective of bonding strength in splash guard welding simultaneously, annotate between concrete and occur leaking, seeping water can occur waterproofing course and secondary lining mould under higher Water Pressure, thereby do not have due waterproof ability.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of full-packaging waterproof layer edge-sealing water-tight device for the tunnel is provided, this device comprises the compressed steel bar, press down steel bar and waterproofing course limit end, and the three is bolted.
The object of the invention realizes being completed by following technical scheme:
A kind of full-packaging waterproof layer edge-sealing water-tight device for the tunnel, the steel work that comprises interface channel between the tunnel, it is characterized in that: this water-tight device comprises the compressed steel bar, press down steel bar and waterproofing course limit end, the described steel bar that presses down is fixed on described steel work, described waterproofing course limit end is at upper compressed steel bar and press down on plan-position between steel bar, and it is fixing that upper compressed steel bar and pressing down is bolted between steel bar.
On contact surface on described between compressed steel bar and waterproofing course limit end, pressing down on the contact surface between steel bar and waterproofing course limit end, on the contact surface between bolt and upper compressed steel bar, at bolt and press down on contact surface between steel bar, and be filled with water Expansion sealing glue-line on the contact surface between bolt and waterproofing course limit end.
Described pressing down in the cavity that steel bar and waterproof edges of boards end consist of is provided with the low-modulus polyurethane sealant layer.
Advantage of the present invention is to have fine sealing performance, easy construction, economical and practical by the waterproofing course terminal that water-tight device connects, and the waterproofing course terminal can be born the Water Pressure of 0.9MPa, has higher waterproof safety coefficient deposit.
Description of drawings
Accompanying drawing 1 is embodiment of the present invention water-tight device cross-sectional view;
The specific embodiment

The present embodiment by bolt 5 with upper compressed steel bar 3, press down steel bar 4 and be connected the limit end with splash guard and connect, and guarantee water resistance with fluid sealant, add hydraulic pressure through overtesting and detect, adopt the fixing waterproofing course end part seal performance of the present embodiment can reach the hydraulic pressure resistance ability of 0.9MPa.
The present embodiment water-tight device comprise interface channel between the tunnel steel work 1, upper compressed steel bar 3, press down steel bar 4 and waterproofing course limit end 2, pressing down steel bar 4 is welded and fixed with steel work 1, two adjacent waterproofing course limit ends 2 are in contact with one another, and at upper compressed steel bar 3 and press down on plan-position between steel bar 4, upper compressed steel bar 3 and pressing down between steel bar 4 is connected and fixed by bolt 5.
Be provided with low-modulus polyurethane sealant layer 6 pressing down between steel bar 4 and waterproof edges of boards end 2.
Be the sealing performance of assurance device, also be filled with the glue-line that seals between any two members of device.As shown in the figure, on the contact surface between upper compressed steel bar 3 and waterproofing course limit end 2, pressing down on the contact surface between steel bar 4 and waterproofing course limit end 2, on the contact surface between bolt 5 and upper compressed steel bar 3, at bolt 5 and press down on contact surface between steel bar 4, and all be filled with water Expansion sealing glue-line 6 on the contact surface between bolt 5 and waterproofing course limit end 2.
Obviously, the set-up mode of sealant layer of the present invention is not limited to the mode described in the present embodiment.
