Abstract

The invention discloses a double-wheel milling diaphragm wall structure and a construction process thereof. The construction process comprises the following steps that S1, pre-excavation is conducted, specifically, a plurality of first-stage groove positions which are arranged at intervals are formed firstly, excavation is conducted on the first-stage groove positions in the vertical direction, corresponding soil is carried out of the groove holes, and meanwhile slurry is poured into the groove holes; S2, double-wheel milling excavation is conducted, specifically, the groove holes are further excavated through double-wheel milling, and meanwhile slurry is poured into the groove holes; S3, concrete slurry is poured, specifically, the concrete slurry is gradually poured into the bottom of the groove holes, and meanwhile, slurry is injected, pumped out and temporarily stored; and S4, second-stage groove position forming is carried out, a second-stage groove position is formed between two adjacent first-stage groove positions, and the above operation is repeated. The double-wheel milling diaphragm wall structure has the effect of reducing the risk that the soil layer on the peripheral side of the groove hole is prone to collapse, and the risk of sludge accumulation at the bottom of the groove hole can be reduced.

Description

technical field [0001] The present application relates to the field of anti-seepage wall structures, in particular to a double-wheel milling anti-seepage wall structure and its construction technology. Background technique [0002] The anti-seepage wall is an underground anti-seepage structure built by using special machines to create holes in the loose permeable foundation of the gate dam, and pouring concrete or cement clay mortar into the holes. The anti-seepage wall is built in sections, a slot is built into a wall section, and many wall sections are continuous to form a whole wall, so it is also called an underground continuous wall. Double-wheel milling is a kind of excavation equipment, which has the advantages of strong stratum adaptability and high drilling efficiency and precision, so it is widely used in the construction of cut-off walls. [0003] The Chinese patent with the application number CN201911221395.7 in the related technology proposes a construction pro...
