Single-wheel groove milling equipment and construction method thereof for underground diaphragm wall grooving

Abstract

The invention discloses single-wheel groove milling equipment and a construction method thereof for underground diaphragm wall grooving. The single-wheel groove milling equipment comprises a groove milling device and a waste soil discharging device; the groove milling device comprises a residue spraying pipe which is vertically arranged in an underground drilled hole, a single-wheel groove milling machine is disposed on one side of the residue spraying pipe, a limiting guide way is disposed on the residue spraying pipe in the length direction, and the single-wheel groove milling machine moves along the limiting guide way; the waste soil discharging device is communicated with the bottom of the residue spraying pipe, and soil layer milling is performed by the single-wheel groove milling machine through repeated translation of the residue spraying pipe in a groove section. Compared with the prior art, the single-wheel groove milling equipment and the construction method thereof for underground diaphragm wall grooving have the advantages that the equipment is suitable for being used in the geologic environment with hard stratums, and underground diaphragm wall grooving operation with a short construction period, good grooving quality and small investment can be achieved.

Description

technical field [0001] The invention relates to a single-wheel groove milling equipment for forming grooves in an underground continuous wall and a construction method thereof, belonging to the technical field of building construction. Background technique [0002] Underground diaphragm wall is the main construction method for deep foundation pit support and dam seepage-proof underground foundation. In general soil layers, the use of hydraulic grab buckets for grooving operations can meet the construction requirements. However, with the widespread use of underground diaphragm walls, The construction of various complex strata is also emerging in endlessly. Only using hydraulic grabs for trough construction can no longer meet various complex geological structures. There are unfavorable factors. The use of percussion drills will lead to long construction periods and poor groove quality. In some rock formations and gravel layers, percussion drills have almost no work efficiency....

[0002] Underground diaphragm wall is the main construction method for deep foundation pit support and dam seepage-proof underground foundation. In general soil layers, the use of hydraulic grab buckets for grooving operations can meet the construction requirements. However, with the widespread use of underground diaphragm walls, The construction of various complex strata is also emerging in endlessly. Only using hydraulic grabs for trough construction can no longer meet various complex geological structures. There are unfavorable factors. The use of percussion drills will lead to long construction periods and poor groove quality. In some rock formations and gravel layers, percussion drills have almost no work efficiency. Using more advanced double-wheel milling for construction will cost a lot
