The groove shaping support according to claim 1 is characterized in that: A support rod (1) is arranged between the support plates (4), and blocks (37) are fixed at both ends of the support rod (1). A locking hole (38) is provided on the surface of the block (37), and the block (37) can be embedded in the slot (26). The locking rod (22) can be inserted into the locking hole (38). The vertical plate (24) is in the shape of a square plate, and the locking rod (22) is located at the center of the vertical plate (24). The vertical plate (24) is provided with anti-slip patterns (23) on the upper and lower inner sides.

8. The groove shaping support according to claim 1, characterized in that: The first mounting hole (12) passes through the vertical support beam (13), a plurality of first mounting holes (12) are provided, and the plurality of first mounting holes (12) are evenly distributed on the surface of the vertical support beam (13), and a plurality of transverse columns (33) are provided, and the plurality of transverse columns (33) are evenly distributed on the support plate (4).

9. The groove shaping support according to claim 1, characterized in that: The surface of the transverse column (33) is provided with a bearing groove (36), and two groups of bearing grooves (36) are provided. The two groups of bearing grooves (36) are symmetrically distributed about the central axis of the transverse column (33). The inner extension plate (34) can extend into the interior of the support plate (4) and abut against the vertical support beam (13). The second mounting hole (35) corresponds to the first mounting hole (12) and is connected by bolts.

10. The construction method of groove shaping support according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: First, place the support plate (4) from top to west on the inner wall of the groove (3), then insert the fixing steel bar (7) from top to bottom into the insertion hole (8) until the fixing steel bar (7) is inserted into the ground (2) for fixing, and then, extend and install the remaining support plates (4) on both sides of the fixed support plate (4); S2: Move the support plate (4) to be installed from top to bottom, make the outer sliding block (10) and the inner sliding groove (9) correspond to each other, so that the two support plates (4) are closely aligned, and then install and fix the steel bars (7), and fix the support plates (4) on both sides of the groove (3) in the same way; S3: After the support plates (4) on both sides of the inner wall of the groove (3) facing each other are arranged, it is necessary to install a first connecting frame on the support plates (4), and install a support rod (1) on the first connecting frame to achieve mutual support of the support plates (4) on both sides; S4: After fixing the support plates (4) on both sides of the inner wall of the groove (3), select a suitable position for reservation, install the walkway plate (6) on the support plates (4) at the reserved position, install the support frame (5) on the remaining support plates (4), and install the second connecting plate on the support plates (4) at the reserved position, so as to facilitate the workers to enter the groove (3) for construction.
