[0030] When the limiting cover plate 106 is installed on the connecting seat 101, the four groups of clamping blocks 109 are respectively inserted into the connection grooves 110 at one end of the four groups of beam plates 102, which are used for the connection and locking of the four groups of beam plates 102 and the connecting seat 101.
[0031] In this embodiment, the geotechnical engineering slope lattice beam structure is used in the construction of the connecting seat 101 and the beam plate 102 on a flat site, and is prefabricated and formed for assembly on the slope.
[0032] First, a plurality of pin rods 103 are fixed and inserted into the slope according to the specified position, and the threaded teeth of the pin rod 103 extend to the outside of the slope, and then the first through hole of the connecting seat 101 is inserted into the pin rod 103 and is attached to the surface of the slope.
[0033] Then, the beam plate 102 is lifted by a lifting device (not shown in the figure) and is clamped in the clamping groove 104 of the adjacent connecting seat 101, and after the assembly of the beam plate 102 is completed, the first through hole and the second through hole of the limiting cover plate 106 are respectively inserted into the pin rod 103 and the threaded column 105, and then the first nut 107 and the second nut 108 are respectively screwed on the threaded column 105 and the pin rod 103, which are used for the connection and locking of the limiting cover plate 106 and the connecting seat 101.
[0034] At this time, the limiting cover plate 106 can limit the beam plate 102 up and down, and the two groups of connecting seats 101 can limit the beam plate 102 left and right and front and back, and the connecting seat 101 is fixedly connected with the slope through the pin rod 103.
[0035] When the limiting cover plate 106 is installed on the connecting seat 101, the clamping block 109 is clamped in the connection groove 110, so as to realize the connection and locking of the connecting seat 101 and the four groups of beam plates 102, and the structure realizes the construction of the lattice beam.
[0036] This scheme makes it possible to construct the slope prefabricated frame lattice beam structure on a flat site, avoids a series of technical problems caused by the high difficulty of slope construction, and after the prefabricated connecting seat 101 and beam plate 102 are spliced and assembled by lifting, the construction of the lattice beam is completed, which is convenient for the staff to operate and install the lattice beam, improves the work efficiency, and thus speeds up the construction speed.
