Construction method of underground construction

Abstract

The invention discloses an underground construction constructed in an assembled mode and a construction method of the underground construction. The underground construction mainly comprises prefabricated underground diaphragm walls, steel latticework stand columns, prefabricated piles, prefabricated main beams, section steel secondary beams and first layer prefabricated prestress floor slabs, wherein the prefabricated underground diaphragm walls, the steel latticework stand columns, the prefabricated piles, the prefabricated main beams, the section steel secondary beams and the first layer prefabricated prestress floor slabs are assembled and constructed in a prefabricated mode and prefabricated in a factory. The upper prefabricated underground diaphragm wall and the lower prefabricated underground diaphragm wall are connected through bolts. The left prefabricated underground diaphragm wall and the right prefabricated underground diaphragm wall are connected in a plug pin mode. Upper sections and lower sections of the prefabricated piles are connected through pile end embedded steel plates in a welded mode. The steel latticework stand columns are connected with the upper sections of the prefabricated piles through bolts. The prefabricated main beams are connected through main beam connection node bolts. The section steel secondary beams are connected with the prefabricated underground diaphragm walls and the prefabricated main beams through bolts. According to the underground construction constructed in the assembled mode and the construction method of the underground construction, temporary construction materials and labor cost are reduced, construction efficiency is improved through on-site mechanized construction, and the composite engineering cost is lower compared with a traditional construction method; top plates of an underground structure of the underground construction are formed quite fast, therefore, the original ground state can be recovered quickly, noise and dust pollution on a construction site are reduced greatly, and environment-friendly construction is realized truly.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of an underground building for assembly construction. Background technique [0002] With the rapid growth of urban development and urban population in my country, urban land resources are becoming increasingly scarce, and the focus of land development and utilization has shifted from the ground to the underground space. At present, the construction methods of underground engineering in my country are basically based on the traditional construction techniques of steel bar binding, formwork support, and concrete pouring at the construction site. This traditional construction method not only causes a lot of waste of building materials, but also in many cases (such as Low temperature weather in winter) can not guarantee the quality of the project, and the operation efficiency is low and the construction period is long. By using modern industrial me...
