Description
Technical Field
The utility model relates to a immersed tube tunnel construction technical field especially relates to vertical steel shear key installation frock of tube coupling joint.
Background
The immersed tube tunnel is characterized in that tunnel tube sections are prefabricated in sections, and temporary water stopping heads are arranged at two ends of each section of the tunnel tube sections. And floating the pipe sections to the axis of the tunnel, then sinking the pipe sections into the pre-dug foundation trench, and completing the underwater connection among the pipe sections through various measures of pipe joint joints.
In order to ensure the stability of the pipe section after sinking and butt joint, the vertical displacement of the pipe joint needs to be limited. The existing measures for limiting the vertical displacement of a immersed tube joint in an immersed tube tunnel are to install a vertical steel shear key or a vertical concrete shear key, and limit the relative displacement of two adjacent sections of tube sections by erecting the shear key, which is described in the text as a vertical steel shear key. A commonly used vertical steel shear key is shown in fig. 1 and 2, taking an xiangyang fish girl tunnel as an example: the height H1 of the middle wall shear key is 2.1m, the width L1 is 0.55m, the thickness is 0.95m, and the weight is about 3.1 tons; the height H2 of the side wall shear key is 1.65m, the width L2 is 0.45m, the thickness is 0.95m, and the weight is about 2.3 tons.
The existing shear key is installed in place by adopting a chain block hoisting mode, but the installation mode has the following three disadvantages: firstly, hoisting eye plates need to be welded on the top of an end steel shell of a pipe joint connector and a shear key, a GINA water stop, an OMEGA water stop and a shear key body in a pipe section can be damaged to a certain extent, the hoisting eye plates need to be detached and subjected to secondary corrosion prevention after construction is completed, construction procedures are complex, and the construction period can be prolonged. Secondly, the space of the pipe joint is narrow and small, which is not beneficial to the installation of hoisting facilities. Take Xiangyang Yulianzhou tunnel as an example: the inner side surface of the side wall shear key is almost close to the vertex of the OMEGA water stop belt; the distance between the top of the shear key on the middle wall and the top of the end steel shell and the top of the OMEGA water stop belt is only 0.6m; the distance between the top of the shear key on the side wall and the top of the end steel shell and the top point of the OMEGA water stop belt is only 0.2m, and the installation difficulty of hoisting facilities is high. Thirdly, the maximum weight of the shear key is 3.1 tons, the minimum weight is 2.3 tons, the shear key is lifted in place completely by manpower, the width of a pipe joint is only 1.15m, and the construction personnel can not conveniently stand and the shear key can not be installed in place; the installation of end steel shell top hoisting facilities relates to high altitude construction and operation of starting a fire, and the danger coefficient is great, has very big potential safety hazard, and the construction degree of difficulty is high, efficient.
Another mode adopts an automatic forklift, as shown in fig. 3, the forklift lanes can be opened and closed synchronously, the performances of forward tilting, backward tilting and synchronous lifting can be realized, and the shear keys are assisted to be installed in place. Take Xiangyang Yulianzhou tunnel as an example: the lifting height of the shear key on the middle wall is 3.9m, the lifting height of the shear key on the side wall is 3.1m, and the lifting height of the forklift is only 2.7m, so that the in-place installation requirements of the shear keys on the middle wall and the side wall cannot be met.
