Abstract
The utility model discloses an embedded rubber waterstop structure for underground engineering, which comprises a rubber waterstop body arranged in a construction joint of an underground engineering structure, wherein the rubber waterstop body positioned in the construction joint forms a telescopic section which is close to the outside soil-facing surface of the underground engineering structure; the both sides portion of rubber waterstop body respectively with the end wall of construction joint contacts, and the both ends of rubber waterstop body are respectively through fixing bolt, rubber gasket, steel clamp plate, steel gasket, nut fixed mounting on the inside face of construction joint structure is vacant. This structure not only can realize that waterstop and major structure surface are closely laminated, can effectively improve the closure of structure seam department waterstop simultaneously, reduces later stage structure seam department waterstop maintenance cost.
Description
Technical Field
The utility model relates to an underground works waterproof field of structure, in particular to embedded rubber waterstop structure for underground works.
Background
When concrete is poured and constructed in underground engineering, on one hand, due to the fact that a main structure cannot be continuously poured, on the other hand, due to the fact that the main structure of the engineering is not uniformly settled, the concrete structure is shrunk by temperature, foundation deformation and the like, structural joints such as construction joints, deformation joints, shrinkage joints and the like need to be reserved in the main structure according to geological structures and design requirements of the engineering. The structural joint is used as a waterproof weak link and part of the main structure of the underground engineering, and on one hand, the main structure loses self-waterproof capability due to structural disconnection at the structural joint; on the other hand, the width of the structural joint can be changed along with the change of the environmental temperature, so that the waterproof difficulty of the structural joint is increased.
At present, the traditional underground engineering structure seam often adopts "mainly prevents" mode to carry out the shutoff to the percolating water, and the waterproof structure of adoption is mostly the rubber waterstop, and the rubber waterstop is different according to the mode of setting, and the subdivision is two types of outer formula and the formula of burying of going into again. However, from the application effect, the external-attached water stop has narrow construction space, so that the installation quality is not easy to meet the design waterproof requirement; the buried water stop is positioned in the middle of the concrete structure, and is difficult to maintain and replace when the waterproof performance is failed. Therefore, no matter which method is adopted, the sealing effect between the rubber water stop and the main structure of the underground engineering is poor, and the adopted reinforcing measures are insufficient, so that the waterproof effect obtained by the method is not ideal, and the water leakage phenomenon at the structural joint is still severe.
Disclosure of Invention
An object of the utility model is to provide an embedded rubber waterstop structure for underground works, this structure not only can realize that waterstop and major structure surface closely laminate, can effectively improve the closure of the waterstop of structure seam department simultaneously, reduces later stage structure seam department waterstop maintenance cost.
The utility model aims at realizing the structure, which comprises a rubber waterstop body arranged in a construction joint of the underground engineering structure, wherein the rubber waterstop body in the construction joint forms a telescopic section which is close to the outside soil-facing surface of the underground engineering structure; the both sides portion of rubber waterstop body respectively with the end wall of construction joint contacts, and the both ends of rubber waterstop body are respectively through fixing bolt, rubber gasket, steel clamp plate, steel gasket, nut fixed mounting on the inside face of construction joint structure is vacant.
The telescopic section is M-shaped, circular, semicircular, W-shaped or V-shaped.
The two side ends of the steel pressing plate, which are close to each other, are both arc-shaped and are bent upwards and compress the bending part of the rubber water stop belt body. Ensure the sealing belt to be closely attached to the structure along the longitudinal direction and the transverse direction of the seam.
The telescopic section can also be arranged at the required positions of deformation joints, contraction joints and the like.
In some embodiments, the rubber sealing strip further comprises a sealant coated on the structural surface and the surface of the rubber sealing strip. This structure not only can realize that waterstop and major structure surface are closely laminated, can effectively improve the closure of structure seam department waterstop simultaneously, reduces later stage structure seam department waterstop maintenance cost.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the structure of the present invention.
Detailed Description
An embedded rubber waterstop structure for underground engineering is shown in figure 1 and comprises a rubber waterstop body 2 arranged in a construction joint of the underground engineering structure, wherein the rubber waterstop body in the construction joint forms a telescopic section 3, and the telescopic section 3 is close to the outer soil facing surface 10 of the underground engineering structure; both sides portion of rubber waterstop body 2 respectively with the end wall of construction joint contacts, and the both ends of rubber waterstop body 2 are respectively through fixing bolt 8, rubber gasket 4, steel clamp plate 5, steel gasket 6, nut 9 fixed mounting on the inside of construction joint structure faces on empty surface 12.
The telescopic section 3 is M-shaped, circular, semicircular, W-shaped or V-shaped.
And two side ends 11 of the steel pressing plate 5, which are close to each other, are both in an arc shape bent upwards and compress the bent part of the rubber water stop belt body. Ensure the sealing belt to be closely attached to the structure along the longitudinal direction and the transverse direction of the seam.
