Description

Technical Field

[0001] The invention relates to the technical field of guide wall groove excavation, in particular to an underground continuous wall guide wall groove excavation device. Background Art

[0002] The TRD cement-soil cut-off wall (a cement-reinforced underground continuous wall construction method) uses a chainsaw-type cutter as its primary tool. The cutter is connected to the main machine during insertion into the foundation. The revolving cutter chain can move vertically or horizontally to cut the underground soil, while cement is used as a hardener. The TRD seamless cement-soil wall offers excellent water-stopping and soil-retaining properties, replacing retaining structures such as ground-connected walls, cast-in-place piles, and triaxial mixing piles (SMW method). The cutter cuts the soil at the construction site to the designed depth and width of the retaining wall. Cement slurry hardener is sprayed from the cutter tip and injected simultaneously with high-pressure air to thoroughly mix and consolidate the in-situ soil, forming a continuous wall of uniform thickness underground. During the specific construction, two corresponding grooves are first drilled out by a drilling rig, and then the soil in the two grooves is grabbed by a hydraulic bucket trencher to form a guide wall groove. Then, suitable materials such as reinforced concrete are poured into the guide wall groove to form an underground continuous wall with anti-seepage, soil retaining and load-bearing functions.

[0003] At present, when digging the soil inside the guide wall groove, a bucket is used to dig the soil. After the digging is completed, the soil is lifted and then poured into the dump truck. Then the bucket returns to the guide wall groove to dig the soil. The back and forth operation is repeated, which is time-consuming and labor-intensive, and reduces the overall work efficiency. At the same time, when it is necessary to dig the soil in the guide wall groove on the other side, the position of the crane equipment needs to be changed to adjust the direction of the bucket. Such back and forth operation is very inconvenient. At the same time, when digging, it is not convenient to extract the underground seepage water well, which causes the excavated soil, mud and water to mix, increasing the difficulty of digging.
