Designing and construction structure of beam and plate structure underground garage comprehensive pipe rack

Abstract

The invention provides a design and construction structure of a beam-slab structure underground garage comprehensive pipe gallery, which includes an N-1 basement. From the first basement to the N-1th basement, each layer goes to the The interior of the basement on the first floor is provided with a partition wall one and a partition wall two in sequence, and each basement is also provided with an exhaust duct and an air inlet duct used as ventilation and air conditioning equipment; The channel formed between the walls; the air inlet channel of each layer is the channel formed between the first partition wall of this layer and the second partition wall of this layer; the first partition wall of each layer is arranged oppositely, and the second partition wall of each layer is arranged oppositely. This structure can uniformly arrange the ventilation and air conditioning equipment pipelines, water supply and drainage pipelines and electrical pipelines in the comprehensive pipe gallery in the basement, which not only reduces the possibility of water leakage and air leakage to improve safety performance, but also greatly reduces the height of the basement and reduces the construction of the basement. The excavation depth of the foundation pit can increase the parking area and reduce the construction cost of the foundation pit.

Description

technical field [0001] The invention relates to the field of underground garage design in construction engineering, and more specifically relates to a design and construction structure for a comprehensive pipe gallery of an underground garage with a beam-slab structure. Background technique [0002] The current layout of the basement from top to bottom is the upper floor slab, upper floor beams, ventilation and air conditioning equipment pipes, water supply and drainage pipes, electrical pipes, floor clearance, and the floor slab of this floor. For the space layout, see figure 1 . The section size of ventilation and air conditioning equipment pipes is relatively large, the section width is usually in the range of 120mm to 4000mm, and the height is usually in the range of 200mm to 630mm. Because it is supported by the pipe hanger and erected at the bottom of the upper beam, it needs to occupy a height of about 250mm to 700mm space, resulting in the minimum floor height of th...
