Description

Water stop positioning and connecting device and construction method

Technical Field

The invention relates to the technical field of tunnel waterproofing, in particular to a waterstop positioning and connecting device and a construction method.

Background

After the tunnel is excavated and formed, a lining concrete is sprayed on the inner wall of the tunnel, and after the lining concrete is formed, a second lining concrete is poured. In order to ensure the construction quality, the tunnel is divided into a plurality of sections according to the set length, and construction is carried out in a sectional mode. In the construction process, construction joints exist at the joints of two adjacent construction sections. In the process of pouring the secondary lining concrete, each construction section is also constructed in sections. Typically, the tunnel is cylindrical and each construction section is cylindrical. The pouring sequence of the secondary lining concrete of each construction section is a lower inverted arch and an upper annular arch, and a construction joint exists on the contact surface of the lower inverted arch and the upper annular arch. As mentioned above, the construction joints are not properly treated, and the water leakage phenomenon may occur in the course of using the tunnel.

In order to avoid the influence on the normal use of the tunnel due to water leakage, a longitudinal water stop is arranged in a construction joint between the lower inverted arch and the upper annular arch. Typically, the longitudinal water stop strip is disposed in the end face of the lower inverted arch section along the part below the axis and the longitudinal water stop strip is disposed in the end face of the upper ring arch section along the part above the axis. The longitudinal water stop is made of rubber materials, the water stop ribs capable of improving the deformation degree are arranged on the surface of the longitudinal water stop, and under the squeezing of the lower inverted arch and the upper ring arch, the longitudinal water stop is likely to deform, so that the close connection between the construction joint between the lower inverted arch and the upper ring arch and the longitudinal water stop cannot be realized, and the hidden danger of water leakage cannot be eliminated. Meanwhile, an annular water stop belt is arranged in a construction joint at the joint of the two adjacent construction sections. The annular water stop comprises an upper water stop band and a lower water stop band, the upper water stop band is arranged between the upper ring arches of the two adjacent construction sections, the lower water stop band is arranged between the inverted arches of the two adjacent construction sections, and the upper water stop band is laid by one side of the construction section constructed in advance; after the inverted arch construction is completed, a lower water stop belt with enough length needs to be reserved, then an upper annular section is constructed, the upper water stop belt is installed, the upper water stop belt and the lower water stop belt need to be combined into an integral annular shape, and the lower water stop belt needs to be connected with the longitudinal water stop belt. Because the construction surface of the joint of the longitudinal water stop and the lower water stop is narrow, the connection difficulty is increased, the connection effect is poor, the connection effect can be lost along with the time, and the hidden danger of water leakage cannot be eliminated.

Therefore, a water stop positioning and connecting device and a construction method are needed to solve the above problems.
