Embodiment Construction
[0012] Such as Figure 1~4 Shown: Weld the two ends of the steel bar 152 on the inner side of the angle iron sheet 151, and then weld the angle iron 15 of a certain length together to form a plane square angle iron; The iron 15 forms the preliminary formwork of the sharp corner structure 14 at the bottom of the side frame member 1, and pours cement thereinto. 1. After sinking to a certain depth along the sharp corner structure 14 at the lower edge of the bottom, a reinforced concrete frame with an inwardly inclined outer wall is poured on the upper edge. After it solidifies, continue to dig to make it sink to a certain depth, and so on until the set depth is reached; pour reinforced cement slabs at the bottom edge of the sharp corner structure 14 for bottom sealing treatment, and form the bottom member 2 after solidification; use a jack to pass the pre-cast cement reinforcement anchor pile 3 through the reserved hole 13 to incline Push upward into the outer soil, use cement t...

The invention relates to a novel underground building and a construction method thereof, and provides an underground building and a construction method thereof. The method of simultaneous excavating and integral casting of a reinforced cement structure is adopted. The underground building and the construction method have the advantages that the cost is low, the structure is firm, and the construction is simple; by adopting an inwards titled outer wall and a tip corner structure of the lower edge of the bottom part, the underground drag of the underground building in the excavation and building process is effectively reduced; on the basis of providing sufficient structure rigidity, the usage amount of material is reduced, and the cost is reduced; the difficult problems of soil collapsing, water permeability and the like in the traditional excavating process are greatly reduced; by arranging an anchoring pile, the anti-pulling capability of the underground building is greatly improved.
Description
technical field [0001] The invention relates to a building structure and its method, in particular to a novel underground structure and its construction method. Background technique [0002] With the rapid development of economy and society, urban and rural populations gather in major cities at an accelerated rate, and urban space becomes increasingly crowded. In order to solve the problem of tight land supply and demand and ensure the intensive and economical use of land, the development of underground space has gradually become an innovative attempt by urban planners. However, there are many difficulties in the construction of underground structures, such as soil collapse, underground water seepage, long construction period and high cost, etc., all of which restrict the progress of my country's underground space development. Contents of the invention [0003] The object of the present invention is to provide a novel underground structure with low cost, firm structure an...
