Embodiment Construction

[0028] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] Such as figure 1 The field of waterproofing of tunnel longitudinal construction joints is shown, specifically a connection structure and connection method for waterproofing steel edge waterstops of tunnel longitudinal construction joints.

[0030] The construction joint between the inverted arch and the arch wall of the tunnel is designed as a steel edge waterstop, and the connection between the sections of the steel edge waterstop adopts a combination of steel plate riveting and rubber bonding. According to the test bonding length to meet the tensile force and impermeability it bears when it deforms, determine its bonding length. After testing, it is determined that the lap length of the end of each steel edge waterstop is 200mm, which is the best. Of course, the designed lap range exceeds 200mm, and the same technical e...

Abstract

The invention relates to the field of waterproofness of longitudinal construction joints of tunnels, and particularly relates to a connecting structure and method for steel-edged rubber water stops which are used for a longitudinal construction joint of a tunnel. In the connecting structure, the rubber parts at the ends of two adjacent steel-edged rubber water stops are bonded by using glue; and the steel-edged parts at the ends of the two adjacent steel-edged rubber water stops are riveted. The connecting method comprises the following steps of: polishing the rubber parts at the ends of the two adjacent steel-edged rubber water stops to eliminate a middle elastic rubber ring of each rubber part; then bonding the ends of the two adjacent steel-edged rubber water stops; finally, riveting the steel-edged parts of the bonded ends. The common problem that the longitudinal construction joint of the tunnel is likely to leak water is solved, so that the technical problem that the water leakage is likely to happen due to the insecure mounting and connecting of the steel-edged rubber water stops in the construction joint and a deformation joint is solved; the efficiency of a construction team is greatly increased; and the connecting structure not only is reasonable in structure and reliable in construction quality, but also is economic and reasonable and wide in application scope.

Description

technical field [0001] The invention relates to the field of waterproofing of longitudinal construction joints of tunnels, in particular to a connection structure and a connection method for waterproof steel edge waterstops of longitudinal construction joints of tunnels. Background technique [0002] In the tunnel construction of general large projects, due to the continuous pouring of concrete, or the deformation of the foundation, the thermal expansion and contraction of concrete components caused by changes in construction technology and temperature, it is necessary to leave construction joints and settlement joints, etc. , Waterstops must be installed at these seams to prevent water leakage. The longitudinal construction joint design of tunnel engineering generally adopts steel edge waterstop for waterproofing. Steel edge waterstop is also called steel edge rubber waterstop. It is divided into strong area and waterproof area. It uses stretchable rubber and galvanized ste...
