Abstract

The invention relates to a fabricated underground diaphragm wall and belongs to the technical field of construction. The lower portion of a connecting base is provided with a trapezoidal groove. The upper portion of the base is provided with locating plates. The inner sides of the locating plates are provided with semicircular grouting holes. The inner side of the lower portion of a base wall is provided with semicircular grouting holes. The midpoints of the two sides of the base walls and standard walls are all provided with semicircular connecting holes. The base walls and the standard wallsare connected and fixed through transverse connecting grooves and transverse connecting blocks. The upper portions of the base walls and the standard walls are provided with circular vertical connecting holes, connecting steel bars and U-shaped bolt mounting holes. The lower portions of the standard walls are provided with vertical connecting columns, U-shaped bolt mounting holes and connecting bar mounting holes. The base walls and the standard walls are connected through the connecting columns and connecting bars. The fabricated underground diaphragm wall has the beneficial effects that thesite construction operability is good, the connecting quality of components is reliable, the assembly operation efficiency is high, the stable connectivity of the underground diaphragm wall and underground soil is enhanced, and the stability of a building is improved.

Description

technical field [0001] The invention belongs to the technical field of underground structure maintenance and construction, in particular to an assembled underground continuous wall. Background technique [0002] After decades of development, the technology of the underground diaphragm wall has been quite mature, among which Japan is the most developed in this technology, and has accumulated more than 15 million square meters. At present, the maximum excavation depth of the underground diaphragm wall is 140m, the thinnest The thickness of the underground diaphragm wall is 20cm. In 1958, my country's hydropower department first used this technology to build a dam cut-off wall at the Danzikou Reservoir in Qingdao. By 2013, most provinces in the country have applied this technology successively. It is estimated that 1.2 million underground diaphragm walls have been built. 1.4 million square meters. Diaphragm walls have been and are being used in many aspects of foundation engin...
