Abstract
The utility model relates to tunnels, in particular to an edge closed device for tunnel, which comprises a steel structure of a connecting channel between tunnels, and is characterized in that a waterproofing device comprises an upper pressure steel bar, a lower pressure steel bar and a waterproof layer edge, wherein the lower pressure steel bar is fixed on the steel structure, the waterproof layer edge is located on a plane between the upper pressure steel bar and the lower pressure steel bar, the upper pressure steel bar is connected with the lower pressure steel bar through a bolt. The edge closed device has the advantages that the waterproof layer edge connected through the waterproofing device has excellent sealing performance, convenient construction, economic and practicability, and the waterproof layer edge can bear the 0.9MPa water pressure, and has higher waterproof safety factor.
Description
Technical field
The utility model relates to tunnel-like, is specifically related to a kind of sealing water-tight device that is used for interface channel waterproofing course between the tunnel, the end locking device of full-packaging waterproof layer on promptly a kind of tunnel wall.
Background technology
Interface channel between the shield tunnel, the general bag waterproof homework entirely that adopts in Mine Method tunnel, the main material of full-packaging waterproof layer is ECB, PVC, its final end sealing is very important.
Briefly introduce the tunnel water proofing technology of domestic common employing below by Xiamen Xiang peace seabed tunnel waterproofing.The seabed tunnel waterproofing mainly comprises: the thin portion 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 the preliminary bracing with cement nail and plastic washer, use then 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 heat-sealing machine of creeping automatically 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 to inflate the leakproofness of checking weld seam.
Waterproof roll fabric width 2.1M, need the polylith splash guard to connect so constitute waterproofing course, problems such as easy rosin joint or failure welding during welding, also there is the not enough defective of bonding strength in splash guard welding simultaneously, annotate between the concrete and occur leaking, seeping water can occurring waterproofing course and secondary lining mould under the higher hydraulic pressure effect, thereby do not have due waterproof ability.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, and a kind of edge-sealing device that is used for the tunnel is provided, and this device comprises the compressed steel bar, presses down steel bar and waterproofing course limit end, and the three passes through bolt.
The utility model purpose realizes being finished by following technical scheme:
A kind of edge-sealing device that is used 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, presses down steel bar and waterproofing course limit end, the described steel bar that presses down is fixed on the described steel work, described waterproofing course limit end is at last compressed steel bar and press down on the plan-position between the steel bar, and last compressed steel bar and pressing down between the steel bar is connected and fixed by bolt.
On the contact surface on described between compressed steel bar and the waterproofing course limit end, pressing down on the contact surface between steel bar and the waterproofing course limit end, on the contact surface between bolt and the last compressed steel bar, at bolt and press down on the contact surface between the steel bar, and on the contact surface between bolt and the waterproofing course limit end, be filled with water Expansion sealing glue-line.
Described pressing down in the cavity that steel bar and waterproof edges of boards end constitute is provided with the low-modulus polyurethane sealant layer.
The utility model has the advantages that the waterproofing course terminal that connects by water-tight device has fine sealing performance, easy construction, economical and practical, the waterproofing course terminal can be born the hydraulic action of 0.9MPa, has higher waterproof safety coefficient deposit.
Description of drawings
Accompanying drawing 1 is the utility model embodiment water-tight device cross-sectional view;
The specific embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:

Present embodiment will be gone up compressed steel bar 3, press down steel bar 4 and be connected with splash guard 2 limit ends by bolt 5, and guarantee water resistance with fluid sealant, add hydraulic pressure through overtesting and detect, adopt the fixing waterproofing course end sealing performance of 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, go up compressed steel bar 3, press down steel bar 4 and waterproofing course limit end 2, it is fixing with steel work 1 welding to press down steel bar 4, two adjacent waterproofing course limit ends 2 are in contact with one another, and at last compressed steel bar 3 and press down on the plan-position between the steel bar 4, last compressed steel bar 3 and pressing down between the 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 the 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 last compressed steel bar 3 and the waterproofing course limit end 2, pressing down on the contact surface between steel bar 4 and the waterproofing course limit end 2, on the contact surface between bolt 5 and the last compressed steel bar 3, at bolt 5 and press down on the contact surface between the steel bar 4, and on the contact surface between bolt 5 and the waterproofing course limit end 2, all be filled with water Expansion sealing glue-line 6.
Obviously, the set-up mode of sealant layer of the present utility model is not limited to the mode described in the present embodiment.
