[0044] The first traction device 500 is disposed at one end of the beam 200 away from the gallery bracket 300 for traction the gallery segment 800 to the gallery bracket 300.

[0045] The side feeding apparatus provided by the present invention has the following processes:

[0046]In the transport stage, the transport pavement 600 is disposed in a direction away from the pit bracket 300 near the top of the pit 100 to the direction away from the foundation pit 100, and the gallery caravan 700 carries the gallery segment 800 to the beam by the transport pave 600. 200 is provided with one end of the gallery bracket 300, when the larbot caver 700 is loaded with the gallery segment and the gallery bus 700 is operated to the end of the beam 200, the gallery car is fixed to the beam 200, at this time, The top of the gallery 700 is parallel to the top of the gallery bracket 300, or is the bottom of the gallery segment 800 and the top of the gallery bracket 300, and in the extended direction of the foundation pit 100, the gallery segment 800 and the gallery bracket 300 is correct.

[0047] After the traction stage, when the gallery bike 700 transports the gallery segment 800 in place, the first traction device 500 is connected to the embedded member of the end portion of the gallery segment 800, and the first traction device 500 will govern the gallerogram. Section 800 is trailed from the gallery bracket 300, and the operation of the traction transfer is completed.

[0048] In the lifting stage, the traveling mechanism of the lifting device 400 drives the crane to operate along the beam 200 to above the gallery bracket 300, so that the spreader and the sprigand segment 800 of the ceiling day, will spread the spreader and the supply After the segment 800 is fixed, the crane will hang the gallery section 800, then walk the mechanism to walk through the crane to drive the gallery section 800 to the preset installation position, and then the caid will gather the gallery 800 Put it to the preset installation location.

[0049] The above-mentioned rid of the parallel gallery device, the side feeding apparatus provided by the present invention solves the prior art in the prior art to transport the gallery segment 800 directly below the pulley, which is the gallery segment The problem of inconvenience caused.

[0050] In addition, the existing gallery gallery process, the gallery needs to move on the installed completed gallery segment 800, and in the lateral feeding unit of the present invention, the gallery car is moved in the side of the foundation pit 100, Soil backfilling can be carried out in time, and speed up the construction speed.

[0051] In one embodiment of the present invention, the above-described cross-beam 200 may include a three part, a top, a central and bottom, respectively, wherein the longitudinal section of the central portion is a waist trapezoidal structure, and the waist trapezoidal distal end facing down, the like can be shaped The big end is facing up. The longitudinal section of the top is a rectangle, and the length of the top of the beam 200 is greater than the length of the large end of the waist trapezoid, and the lengths of the top ends of the beam 200 exceed the length of the portion of the middle ends of the cross-beam 200 equal. The longitudinal section of the bottom is also a rectangle, and the length of the bottom of the beam 200 is equal to the length of the bottom end of the cross member 200.

[0052] When the beam 200 is provided on the top of the foundation pit 100, both ends of the bottom of the beam 200 are supported on the slope of the slope of the top of the foundation pit 100, and the base pit 100 includes a three-stage slope as an example, the bottom of the beam 200 The end supports the slope of the three-stage slope 103 of the foundation pit 100, or is supported at the top of the secondary slope 102.

[0053] When the side feeding device provided by the present invention is completed in a certain position, it is necessary to move in the longitudinal direction of the foundation pit 100 to the next laying position. Therefore, the side feeding apparatus provided by the present invention further includes a sliding device, the sliding device can be disposed at the slope of the three-stage slope 103, or is provided at the top of the slope 102, the top of the sliding device The bottom of the beam 200 is in contact.

[0054] The sliding device may be a slide plate having a lower friction coefficient, and the bottom portion of the beam 200 is in sliding contact with the upper surface of the sliding device. Alternatively, the sliding device may be a combination of the track and the track wheel, and the track can be laid at the slope of the three-stage slope 103, extending in the extended direction of the foundation pit 100, the track wheel is disposed at the bottom of the beam 200, during movement, The track wheel scrolls on the track.

[0055] In one embodiment of the present invention, the movement of the beam 200 is preferably slidable in the manner of the sliding plate 900, and the material of the sliding plate 900 can be polytetrafluoroethylene, polytetrafluoroethylene is a high lubricating material, which is in a solid material.
