Abstract

The invention discloses a method for constructing an underground continuous wall by using a cutter-suction head. The method for constructing the underground continuous wall by using the cutter-suctionhead is characterized in that a plurality of travelling cranes, a mud-water separator and tracks are included, wherein the tracks are arranged on the lower surfaces of the travelling cranes, and travelling crane power devices arranged on the tracks are connected with the cutter-suction head through wire ropes; the cutter-suction head comprises a transverse beam, a rectangular cylinder arranged atupper and lower end openings of the transverse beam, a hydraulic device connected to the middle part of the lower surface of the transverse beam, a mud pump connected with a connecting rod of the hydraulic device and two reamers arranged on both sides of the mud pump; and the mud pump is fixedly connected with connecting shafts of the two reamers correspondingly, and the two connecting shafts areconnected with two reamer motors correspondingly. The method for constructing the underground continuous wall by using the cutter-suction head has the characteristic that the underground continuous wall construction can be carried out on a narrow site.

Description

technical field [0001] The invention relates to the technical field of diaphragm wall construction, in particular to a method for constructing an underground diaphragm wall by using a twisting suction head with high construction efficiency. Background technique [0002] The underground diaphragm wall is a long and narrow deep groove excavated on the ground along the peripheral axis of the deep excavation project under the condition of the mud retaining wall. After the groove is cleaned, the steel cage is hung in the groove , and then use the conduit method to pour underwater concrete to form a unit tank section, and then proceed section by section to form a continuous reinforced concrete wall underground as a water interception, anti-seepage, load-bearing, and water-retaining structure. [0003] Utilize hydraulic grab bucket (grooving machine) during present underground diaphragm wall construction to carry out digging into groove, utilize hydraulic groove milling machine to ...
