Embodiment Construction
[0021] Below in conjunction with accompanying drawing, the mold and the construction method of urban rail transit turnout switch machine foundation pit construction of the present invention are described in detail:
[0022] The mold design idea of the urban rail transit turnout switch machine foundation pit construction of the present invention is to pre-design and make several foundation pit molds and sub-divisions in combination with the actual foundation pit size marked in the reserved drawings of the existing urban rail transit switch machine foundation pits. When the construction of the foundation pit is not reserved, the mold blocks are placed in place one by one according to the assembly sequence at the corresponding mileage position of the line, assembled and fixed. and other external action equipment placement requirements. After the molds are placed in place, the construction and ground hardening work will be carried out on the foundation pit of the whole line of s...

The invention provides a die for constructing an urban mass transit turnout point switch foundation pit. The die comprises a point switch host foundation pit die block part and a rail penetrating groove die block part. The point switch host foundation pit die block part comprises six point switch host foundation pit die blocks with the same size. The rail penetrating groove die block part comprises middle rail penetrating groove die blocks and rail penetrating groove die blocks on the two sides. The point switch host foundation pit die block part and the rail penetrating groove die block part are spliced. The invention further provides a construction method of the die for constructing the urban mass transit turnout point switch foundation pit. The die and the method have the beneficial effects that the die with the uniform standard dimensions is utilized for launching the foundation pit construction project, the construction efficiency is improved, and meanwhile the labor cost of manual work is reduced; meanwhile, the reserving precision of the turnout point switch foundation pit is improved through the die, and the deviation of an original method for constructing the foundation pit is reduced to 10 mm from 50 mm; and the time of one day can be saved when each foundation pit is conducted, and the construction progress can be effectively promoted.
Description
technical field [0001] The invention relates to urban rail transit, in particular to a mold and a construction method for constructing foundation pits of turnout machines in urban rail transit. Background technique [0002] With the continuous development and construction of my country's urban rail transit, the reserved engineering of the switch machine foundation pit has become an important content in the infrastructure construction process of the signaling system. For the construction of the foundation pit of the switch machine in the reserved project, the location, shape, size and depth of the foundation pit are mainly considered. These factors will directly affect the installation of the switch machine, and then affect the control of the switch by the switch equipment. effect, and involves driving safety. [0003] Such as Picture 1-1 —As shown in 1-3, in the existing construction process, for the construction of the foundation pit of the switch machine, the constructio...
