firstly, an initially excavated wall surface is preliminarily supported by a plurality of anchor rods (13).

And secondly, after all anchor rods (13) are inserted into the wall surface, the waterproof layer (7) is paved manually, and a layer of cement can be sprayed on the waterproof layer (7) manually after the waterproof layer (7) is paved, so that the waterproof effect is achieved.

Thirdly, manually building fixed supports (16) on the slope platform (4) and the ground plane respectively to ensure that the fixed supports (16) are fixedly arranged on the slope platform (4) and the ground plane respectively, and the handle (18) and the threaded rod (17) are manually rotated in turn, the threaded rod (17) drives the collision frames (9) to respectively move towards the first slope surface (2) and the second slope surface (3), so that all the collision frames (9) respectively collide against the first slope surface (2) and the second slope surface (3) to prevent soil from loosening, after each abutting frame (9) is adjusted, the fixing screw cap (21) is manually twisted, the abutting frame (9) is positioned through the fixing nut (21) and the positioning groove, each limiting rod (19) and each limiting through hole which are arranged play a role in limiting movement, and the cross section of each abutting frame (9) is of a triangular structure, so that the supporting is more stable.

And fourthly, the first catch drain (5) preliminarily collects the accumulated water above the first slope surface (2), the second catch drain (6) collects the accumulated water in the foundation pit surface (1), and the accumulated water is pumped out through a water pump (15) and a water intake pipe (14) respectively.

Fifthly, the worker can transport the soil in the ground surface to the position of the soil accumulating bin (10) through the cart, pour the soil into the soil accumulating bin (10), the soil is conveyed into the hollow vertical bin (24) through the soil inlet, the soil is sequentially conveyed into the feeding boxes (29), the driving motor (25) is started, the driving wheel (26) is driven by the driving motor (25), the driven wheel (27) and the synchronous belt (28) rotate, all the feeding boxes (29) are made to move up and down along the synchronous belt (28), and the soil is sequentially conveyed into the material guide pipe (31) through the feeding boxes (29).

Sixthly, when the soil in the material guide pipe (31) passes through a polished rod (34) on the rectangular frame (33), classification is carried out, small soil blocks directly fall into the soil loosening conveyor through the first discharging pipe (32) to be conveyed, large soil blocks enter the second discharging pipe (35) through classification, and the large soil blocks are conveyed into the soil conveying conveyor (12) through the second discharging pipe (35) to be conveyed, so that blocking during soil conveying is prevented.
