Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention. Referring to fig. 1 and 2, a tunnel invert waterstop protection device, including arranging a plurality of protection reinforcing bars 1 in the tunnel invert end template outside, a plurality of protection reinforcing bars 1 along invert hoop interval equipartition, tunnel invert end template comprises upper portion template 2 that is located the waterstop upside and lower part template 3 that is located the waterstop downside, protection reinforcing bar 1's top and upper portion template 2 fixed connection, bottom and 3 fixed connection of lower part template, the outside protrusion bending type in middle part has the protection chamber 4 that holds the waterstop of leaking the part outward. The tunnel invert waterstop in this embodiment adopts double-deck waterstop structure, including the copper sealing plate 5 on upper portion and the rubber waterstop 6 of lower part.
In this embodiment, a plurality of protection reinforcing bars 1 along the hoop interval equipartition of invert are arranged in the tunnel invert end template outside, utilize the protection network that protection reinforcing bar 1 formed to provide the protection to the hosepipe, can effectively avoid the waterstop to expose the part and suffer construction machinery collision or the operating personnel tramples, and the large tracts of land bending deformation problem can not appear in the waterstop.
In practical application, in order to provide enough protection for the water stop, the protection reinforcing steel bars 1 cannot be arranged too sparsely, and certainly, in order to reduce cost and cannot be arranged too densely, the distance between two adjacent protection reinforcing steel bars 1 is generally controlled to be 40-60 cm.
