Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings.

[0042] Such as Figure 1 to Figure 14 The construction method of the prestressed assembled submerged indoor basement includes the following steps: a. Firstly, the components 12 of the underground space structure are pre-standardized and produced in the factory. Determine the steel bar layout and quantity of the prefabricated component 12 according to the characteristics of the project; b. Carry out setting-out positioning in the room of the warehouse 3, and then arrange the bolt holes 1 evenly along the sideline of the underground space and bury the bolt underground along the bolt holes 1 11. The anchorage section at the bottom of the anchor 11 is grouted to form an anchor body 15, and the anchor drilling has the functions of geological exploration and construction monitoring; c. After reliable connection, the prefabricated components 12 are sequentially inserted into...

Abstract

The invention relates to the field of indoor underground warehouse construction of buildings, in particular to a prestress assembled loaded-sinking type indoor underground warehouse construction method and an underground warehouse structure, the construction method is simple, reliable, easy to implement and low in construction cost, and original building structures are not affected. The construction method comprises the following steps that a, standard design and production are conducted on members in a factory in advance; b, setting-out and positioning are conducted indoors, and then anchor rods are embedded; c, the prefabricated members are sequentially sleeved with the anchor rods through member installing holes; d, tensioning force is applied to prestress jacks synchronously, and the members are pressed into soil under guidance of the anchor rods and conical blade feet; e, according to the method in the step c, new members are sleeved with the anchor rods one by one for further downward construction; f, the peripheral structure of the underground space is completed; g, bottom slabs, floor slabs of all the storeys, a vertical elevator and horizontal movable roller equipment are installed; and h, the indoor ground is recovered, and construction is completed. The construction method is especially suitable for construction of indoor underground warehouses and underground warehouses of adjacent building yards.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method and a basement structure of a prestressed assembled submerged indoor basement. Background technique [0002] With the continuous acceleration of my country's urbanization process, urban land resources are becoming increasingly scarce. Especially in the old urban area located in the center of the city, due to its strong cultural background, convenient transportation, and complete supporting facilities for life services, it has formed a situation where every inch of land is expensive and land prices are rising rapidly. Through the development of the shallow underground space of the existing buildings and the construction of supporting facilities, the usable area can be increased and the use function of the original buildings can be optimized. Utilizing the underground space resources of existing buildings for modernization can greatly improve the evolutio...
