Abstract
The utility model relates to a rubber belt use for joint and water tightness of a main structure for a tunnel spanning ground fissure. The structure of the rubber belt takes the shape of the Chinese character 'gan', and the section structure is divided into two side wings and an extension zone; a thick liquid preventing ledge, a waterproof wire, a mounting bolt hole and a nylon reinforcement layer are arranged on the two side wings; a main body of the extension zone is connected with the two side wings by taking the U shape; a plurality of layers of waterproof blocks are arranged on an extension main body of the extension zone; reservation notches are formed on the waterproof blocks; and the main body of the extension zone is bent into the reservation notches of a tunnel main body by taking the U shape. Therefore, the section structure with the shape of the Chinese character 'gan' greatly improves the extensibility and can be suitable for the deformation of a main structure larger than that of a general industrial and mining area; and when the space between main structures of an upper and a lower discs at the ground fissure generates the vertical diastrophism of 500 millimeters and the horizontal diastrophism of 50 millimeters, a main structure of the waterproof rubber is not damaged and still maintains the original waterproof function. The rubber belt can be directly used for joint and water tightness of the main body structure for the tunnel spanning ground fissure in Xian City of China at present, and not only solves the waterproof technology of subway tunnel spanning ground fissure but also can be directly expanded to tunnel buildings and underground constructions of all tunnels required to span ground fissures.
Description
(1), technical field
The utility model relates to a kind of tunnel and strides ground fissure agent structure seam waterproof rubber strip.It belongs to the subterranean tunnel architectural waterproof material, applicable to present common tunnel construction and underground construction.As: as subterranean railway tunnel, cross-river tunnel, mountain tunnel, mining tunnel, seepage tunnel and underground garage, underground station, underground inhabitation, civil air defense constructions and installations etc.
(2), background technology
Rubber waterproof band (or waterstop) product is widely used in engineering construction, China GB18173.2-2000 " high polymer waterproof material second portion waterstop " has carried out standard to original three kinds of rubber fastening bands (Type B, S type, J type), but this rubber fastening band of three types does not all have at present and strides ground fissure in the tunnel and reserve the direct applied example of special seam.Ground fissure operating mode according to Xi'an subway correspondence, original three kinds of rubber fastening bands all can not satisfy instructions for use, mainly show the section structure deformable amount deficiency of product, take place under the situation of the relative 500mm changing of the relative positions in ground fissure both sides geology, phenomenons such as original three kinds of rubber fastening bands can rupture, pull lost efficacy water resistance.
(3), summary of the invention
The purpose of this utility model provides a kind of tunnel and strides ground fissure agent structure seam waterproof rubber strip, directly apply to current domestic Xi'an subway tunnel and stride ground fissure agent structure seam waterproof, when the solution subway tunnel is striden the ground fissure waterproof technique, also can directly expand in all tunnel constructions and underground construction of crossing over ground fissures.
The purpose of this utility model is achieved like this: ground fissure agent structure seam waterproof rubber strip is striden in the tunnel, its structure is " sweet " shape, section structure is divided into two flanks and zones of extensibility, the plasma resistance fin is set on two flanks, water-proof wire, mounting bolt hole, the nylon enhancement layer, the main body of zones of extensibility is connected in two flanks with " U " shape, multilayer flashing lattice retaining is set on the extension main body, and block design at the waterproof lattice reservation breach arranged, the main body of zones of extensibility bends in the tunnel main body with " U " shape and reserves in the seam, the fin that blocks water of two flanks can be set to inside and outside twice or multiple tracks, water-proof wire can be set to one or multi-channel, mounting bolt hole is along circumferentially evenly distribution and spacing are adjustable, and the nylon enhancement layer can be one or more layers.
Form of structure of the present utility model also can be made into annular, shaped as frame as required.
Ground fissure agent structure seam waterproof rubber strip is striden in tunnel of the present utility model, the section structure of its " sweet " shape rubber fastening band has increased substantially ductility, can adapt to the agent structure distortion bigger than general industrial and mineral, when between ground fissure place upper lower burrs agent structure, producing the horizontal changing of the relative positions of the vertical changing of the relative positions of 500mm and 50mm, the agent structure of water proof rubber is not destroyed, and keeps original water-proof function simultaneously.Its section structure is divided into two flanks and zones of extensibility.Plasma resistance fin, water-proof wire, mounting bolt hole, nylon enhancement layer are set on two flanks, use needs according to engineering, the fin that wherein blocks water can be set to inside and outside twice or multiple tracks, work to stop the injection slurry intrusion waterstop back side, water-proof wire can be set to one or multi-channel, work to stop underground water along the contacting permeation between concrete and the waterstop, circumferentially evenly distribution and spacing are adjustable along product for mounting bolt hole, and the nylon enhancement layer can be one or more layers; The main body of product zones of extensibility bends in the tunnel main body with " U " shape and reserves in the seam; multilayer flashing lattice retaining is set on the product zones of extensibility; As time goes on; when stride between the ground fissure place upper lower burrs agent structure when producing the changing of the relative positions in the tunnel; the multilayer flashing lattice retaining that is provided with on the product zones of extensibility can rupture one by one along reserving breach; water blocking tape extension region main body can extend gradually, can not rupture by the high-elastic characteristic protection of rubber water blocking tape extension region main body, thereby keeps original water-proof function.
Ground fissure agent structure seam waterproof rubber strip is striden in tunnel of the present utility model, select superior ethylene propylene diene rubber (EPDM) material of ageing properties and mechanical property as the product material of main part, adopting nylon reinforcements that the position (around bolt hole) of destructible is strengthened is to guarantee that product is in the long-term key technology of using of underground environment.The structure design uniqueness of product, novelty, main feature are the upstream face multi-way preventions, and when the tunnel agent structure upper lower burrs generation changing of the relative positions and displacement caused the large deformation of product product, the waterproof position of product can provide the function of upgrading step by step.
(4), description of drawings
Accompanying drawing 1 is striden ground fissure agent structure seam waterproof rubber strip section structure schematic diagram for tunnel of the present utility model.
(5), the specific embodiment
