And the hydraulic jack is arranged along the extending direction of the transverse rail, and the output end of the hydraulic jack is fixedly supported on the side wall of the channel steel.
and, first track and second track are the multistage interval setting, and this interval department is connected with the track 5 of passing by the traffic accident through 6 regulation of switch.
In addition, the rail car and the connecting device (connecting hook) between the rail cars adopt mature products in the prior art, and the rail car comprises a plurality of sections of detachably connected battery cars 17, a muck carriage 18, a mortar car 16 and a segment car 15.
In addition, the length of each section of the first track and the second track is not less than 45m, the longitudinal extension of the shield well along the direction of the first track and the second track is not more than 17m, the total length of the rail car is not more than 46m, the maximum height is not more than 1.5m, the maximum width is not more than 2.7m, and the carrying capacity of each section of the muck carriage is 16 earthwork.
In addition, two groups of rail cars run on the preferable rail transport system simultaneously, each rail car comprises a first transport car, a second transport car, a first battery car and a second battery car, wherein each first transport car and each second transport car comprise a muck carriage, a mortar car and a duct piece car, and the first battery car and the second battery car can be connected to any position of the head end, the tail end or the middle part of each first transport car and each second transport car.
To more clearly illustrate the embodiments of the present invention, an example is provided below:
the system comprises a track traversing device arranged in a station end shield shaft, wherein the track traversing device can transversely move within a certain range and is in seamless butt joint with a first track or a second track laid in a track running area in a shield tunnel (or in a station), so that when one group of railcars is unloaded, the other group of railcars is loaded, and the operation is not interfered with each other.
The rail car dispatching method comprises the following steps:
The method comprises the following steps: when the single-ring tunneling of the shield construction is finished (tunnel face tunneling, duct piece laying and mortar discharging), a mortar tank on a mortar vehicle pulled by the storage battery car is filled through a pump pipe and is parked to a standby area (a wrong-way track) to be electrically stirred and wait (at the moment, the first transport vehicle is considered to be fully loaded and connected with the first storage battery car, and is located at the position of the first track to wait for the first transport vehicle;
Step two: starting a hydraulic jack to enable a track transverse moving device to be in butt joint with a first track, driving a first transport vehicle to drive the first transport vehicle to move onto the track transverse moving device from the first track, removing a connecting hook between the first storage battery vehicle and the first transport vehicle, loading and unloading muck, mortar and duct pieces by the first transport vehicle through a gantry crane on the ground, and returning the first storage battery vehicle to a shield wrong vehicle track through the first track to wait;
Step three: after the second step is finished, the hydraulic jack is started again to enable the rail transverse moving device to be in butt joint with the second rail, and the first transport vehicle is connected to the second battery car; at the moment, the second transport vehicle finishes loading and is connected to the returned first battery car, so that a loading and unloading cycle is finished, namely the first battery car drives the second transport vehicle again to sequentially repeat the first step, the second step and the third step; at the moment, the second battery car drives the first transport car to drive the first transport car to move to the wrong track to wait for loading mortar and muck;
In addition, in the present invention, the multi-line tunnel is constructed generally by a single line construction method or a double line simultaneous construction method from a station or a shield shaft (or a block wind shaft) designed separately. If two-line simultaneous construction is performed from a station, one or both of the following two conditions must be met: the first is that material (slag tapping) inlet and outlet are reserved at the corresponding position of the station top plate (middle plate), and the second adjacent interval tunnel is through. Otherwise, when the double-line construction of the superposed line tunnel is carried out, the shield wells at the two ends of the station can be only used for carrying out the construction.
the length of a shield end well (or a middle air shaft) is generally 17m under the split starting working condition of shield tunnel construction, and after the split starting stage is finished, double-line tracks (a first track and a second track) and installation turnouts and staggered tracks can be paved in the formed shield tunnel to meet the requirement of quick construction.
The invention solves the problem that the construction requirement of sequentially discharging slag and feeding materials from the shield wells at the ends of the stations of the rail cars which are arranged in a whole row can not be met because the adjacent tunnels are not communicated when the shield wells at the two ends of the stations are simply utilized for construction, particularly the tunnels below the superposed lines are constructed, effectively improves the slag soil throughput efficiency of the shield construction, and greatly shortens the construction period.
In addition, compared with the transportation and preparation time (shown in table 1) of the traditional construction equipment and method, the transportation and preparation time (shown in table 2) of the invention has obvious transportation capacity advantages, a storage battery car is often adopted to drive one carriage to reciprocate on a single track for transportation in the traditional construction, the method cannot synchronously carry out muck loading and unloading construction, and the volume of the single carriage cannot be enlarged due to the horizontal depth limit of the shield well, so that the transportation capacity is severely limited; the rail transport system effectively solves the problems, and the transport capacity of the rail transport system is 2 times that of the traditional construction equipment within the same time period as can be seen from comparison between the table 1 and the table 2.
it will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
