All-wet joint prefabricated prestressed underground diaphragm wall and construction method thereof

Abstract

The invention discloses an all-wet joint prefabricated prestressed underground diaphragm wall. The all-wet joint prefabricated prestressed underground diaphragm wall comprises a wall body, wherein a reinforcing plate is installed on the outer side of the wall body, side plates are installed on the outer sides of the reinforcing plate, side beam plates are installed at one ends of the side plates, and the side beam plates are located at the top end positions of the side plates; fixed beams are provided with keel fasteners, and connecting shafts are installed at the two ends of the fixed beams; and keels are arranged on the keel fasteners. A lower beam shaft plate is arranged at the bottom end of the all-wet joint prefabricated prestressed underground diaphragm wall, the lower beam shaft plate is provided with lower beam shafts, and the wall body can be effectively fixed through the lower beam shafts, so that the wall body can enter the ground in advance, and the fixation capacity of the placement of the diaphragm wall is further strengthened. A top beam plate and the side beam plates are arranged at the top of the wall body, and the fixation effect of the top of the wall body can be realized in the placement process through the top beam plate and the side beam plates, and a situation of falling off the wall body due to sinking of a surface layer at the bottom end of the wall body is prevented.

Description

technical field [0001] The invention relates to the field of diaphragm walls, in particular to a prefabricated prestressed underground diaphragm wall with full wet joints. Background technique [0002] The continuous wall constructed by using drilling equipment to form a groove section, the underground continuous wall has a large structural rigidity and can play a good supporting role. It is suitable for various geological conditions and can be used as a part of the main body of the underground building to save energy. It reduces the project cost, simplifies the construction procedure, has various functions, and has low construction pollution. It was first applied in Italy. In the 1950s, Italy first adopted the pile-row type underground diaphragm wall, and then it was rapidly promoted in the West. In 1954, it was rapidly applied in France and Germany. Application; In 1959, it was extended to Japan and developed greatly. Japan is currently the country with the most applications...
