Abstract

The invention provides a prefabricated transverse H-shaped underground continuous wall joint section structure. Two side end parts of the cross section of a joint section are provided with semicircular grooves, the middle part of the cross section of the joint section is provided with a circular hole, the joint section is longitudinally divided into a plurality of length sections, a connecting steel plate is arranged at the outer side of the joint of every two length sections, and four sides of the bottom of the joint section are provided with edge feet. The structure has the advantages that: the prefabricated transverse H-shaped underground continuous wall joint section replaces ground connected wall joint equipment and replaces a part of cast-in-place ground connected wall structure, so that the process of pulling the joint equipment is avoided and the construction period and the manufacturing cost are saved; the lower end of the joint section is wedge-shaped and inserted into soil by means of gravity, so that the lower end is effectively fixed, and the width and the quality of the cast-in-place breadth can be effectively ensured; the designed width of the prefabricated continuous wall joint breadth is not less than 1,500 millimeters, and the bypass seepage path of concrete is lengthened; by curved surface design of the contact face of the prefabricated continuous wall joint breadth and the cast-in-place ground connected wall, the seepage problem of the ground connected wall is effectively solved; and the prefabricated continuous wall joint section is made into a member cancelled structure by adopting proper length section by section, so the structure is convenient to transport and hoist.

Description

technical field

[0001] The invention relates to a building basic structure component, in particular to a prefabricated I-shaped underground continuous wall joint section structure. Background technique

[0002] In 1950, Italy began to use underground diaphragm wall technology in reservoir dam engineering, and in 1958, my country introduced this technology. In the mid-1970s, this technology began to be applied to construction, coal mining, municipal and other industries. As an enclosure structure of underground engineering, ground connection wall is widely used in deep foundation pit engineering. It can be used as a temporary retaining and water-stop structure, or it can replace the basement exterior wall as a permanent underground structure.

[0003] The construction of the ground connection wall is mainly divided into: guide wall construction, reinforcement cage production, mud production, trough setting out, trough formation, lower lock pipe, steel cage hoisting and lowe...
