[0008] By adopting the above technical solution, when it is necessary to use a roadbed fence column foundation pit one-time forming machine, the insertion tube is connected to the excavator arm in advance, and then the insertion tube is moved to the location area where the foundation pit needs to be excavated by the excavator. Subsequently, the rectangular frame is brought close to the ground, and then the adjustment component is started. With the help of hydraulic impact force, the working head on one side of the rectangular frame cuts down the soil until the insertion tube is inserted into the ground to a suitable depth. After that, the insertion tube is raised by the excavator arm, and the rectangular frame moves synchronously with the insertion tube. During this process, the soil in the insertion tube is brought out together similar to coring, and the soil in the insertion tube is discharged, thereby forming a column foundation pit. According to the above operation, until all foundation pits are excavated, compared with the related art, the present application can enable the insertion tube to be inserted into the ground according to the specified depth of the foundation pit through the adjustment component, and there is no need for personnel to constantly observe the excavation depth of the foundation pit during the foundation pit excavation process, which is conducive to improving the problem of increased workload of personnel.

At this time, the adjusting plate slides on the outer wall of the insertion tube along the axial direction of the insertion tube opening until the bottom or top of the adjusting plate and the distance between the rectangular frame and the side away from the insertion tube are consistent with the specified depth of the foundation pit, and then the adjusting piece is closed. After that, with the help of hydraulic impact force, the rectangular frame can cut the soil downward, and the insertion tube extends into the soil with the rectangular frame until the bottom or top of the adjusting plate is flush with the ground, and then the insertion tube is lifted out by the excavator, and the soil in the insertion tube is taken out together similar to coring, so that the excavation of the foundation pit can be completed. By setting the adjusting plate and the adjusting piece, the distance between the bottom or top of the adjusting plate and the rectangular frame and the side away from the insertion tube can be adjusted. On the one hand, it is easier for personnel to observe the depth of the insertion tube into the soil, which is conducive to improving the problem of increased workload of personnel; on the other hand, foundation pits of different depths can be excavated.

[0011] Optionally, the adjustment plate is fitted with the outer wall of the insertion tube on one side close to the insertion tube, and a guide plate is fixed to each side of the adjustment plate away from the insertion tube. The guide plates are vertically arranged to the adjustment plate, and the guide plates can contact the soil at the top of the foundation pit. Four adjustment plates are spliced ​​and fixed into an adjustment frame, and the adjustment member is connected to the adjustment frame.

[0012] By adopting the above technical solution, when it is necessary to excavate the foundation pit, according to the required depth of the foundation pit excavation, the personnel start the adjustment part, and the adjustment part drives the adjustment plate to move. During the movement of the adjustment plate, the guide plate moves synchronously with the adjustment plate until the adjustment plate is adjusted to a suitable position. Subsequently, with the help of hydraulic impact force, the insertion tube is inserted into the soil until the guide plate contacts the soil at the top of the foundation pit, and then the insertion tube is lifted out by the excavator. By setting the guide plate, during the process of inserting the insertion tube into the soil, the personnel only need to observe the distance between the guide plate and the soil at the top of the foundation pit, which is conducive to improving the problem of increased workload of personnel.

[0013] Optionally, the adjustment assembly further includes at least one splicing frame and a plurality of connecting pieces, the splicing frame being located between the insertion tube and the rectangular frame, the splicing frame being coaxially arranged with the insertion tube, the insertion tube being fixed with four plugging plates at the opening, one of the plugging plates corresponding to a side wall of the insertion tube, a plugging groove for inserting the plugging plate is provided on a side of the splicing frame close to the insertion tube, the plugging plate and the plugging groove are interference fit, four plugging plates are fixed on a side of the splicing frame close to the rectangular frame, the plugging plates and the plugging grooves can cooperate, one of the plugging plates corresponds to a side wall of the splicing frame, a slot for inserting the plugging plate is provided on a side of the rectangular frame close to the splicing frame, one side wall of the insertion tube corresponds to at least one of the connecting pieces, the connecting piece is connected to the splicing frame, and the connecting piece is used to connect the splicing frame, the insertion tube and the rectangular frame.

[0014] By adopting the above technical solution, when it is necessary to excavate the foundation pit, the appropriate number of splicing frames is selected according to the depth of the foundation pit to be excavated.
