Engineering method of prefabricated and spliced well-sinking type parking garage and parking garage

Abstract

The invention provides an engineering method of a prefabricated and spliced well-sinking type parking garage and the parking garage. The engineering method comprises the following construction steps that 1, a plurality of blade foot blocks are spliced to form a blade foot layer; 2, reinforced concrete is cast into the inner cavity of the blade foot layer at a time, then soil is excavated from the ground defined by the blade foot layer to make the blade foot layer sink in plate; 3, standard blocks are hoisted to be spliced with the top of an installed shaft, and the adjacent standard blocks are spliced in sequence to form an upper layer of the shaft; 4, reinforced concrete is cast into the inner cavity of a standard layer at a time, soil excavation continues till the shaft in the layer sinks in place; 5, the steps 3 and 4 are repeated to install other layers of the shaft till the shaft sinks to reach preset depth layer by layer; 6, concrete is cast on the bottom surface of the shaft in a layered mode to achieve bottom sealing; 7, a garage parking frame body structure is installed, and the top is sealed. The method adopts prefabrication, site splicing and inner cavity concrete casting, the purposes of shortening a construction period, reducing construction interference and reducing pollution are achieved, the advantages of the mechanical properties of a well-sinking structure are fully utilized, and a timbering process and costs during underground excavation are decreased.

Description

technical field [0001] The invention relates to the field of parking garages, in particular to an engineering method of a prefabricated spliced ​​caisson type parking garage and the parking garage. Background technique [0002] With the development of the economy, urban land is increasingly in short supply. Intensive and economical use of land, scientific and rational development and utilization of urban underground space, and development of new living and development space have become an inevitable choice. Many domestic cities have gradually emerged to develop and utilize underground space. upsurge. The development and utilization of underground space can alleviate traffic congestion, reduce urban air pollution, improve urban ecological environment, and facilitate urban people's life. The problems of traffic difficulties, road difficulties and parking difficulties in large and medium-sized cities are common and increasingly serious. [0003] Urban underground parking lots...

AI Technical Summary

Problems solved by technology

However, at present, the civil engineering part of the underground parking garage is usually constructed in the way of pouring in-situ wet work to set up the foundation pit support system and carry out large-scale earth excavation. It not only needs to occupy a large construction area in the construction site, but also wastes a lot of support At the same time, a large number of templates, steel bar processing and production areas, material stacking sites, mortar mixing areas, etc. need to be stacked on the construction site

After the excavation is completed, the support system needs to be removed to cause construction waste. During the construction period, there are problems such as noise disturbance and construction disturbance, and the requirements for safe and civilized construction are not easy to meet

At the same time, it is impossible to realize large-scale excavation for the construction of parking garages in areas where the urban site is small, the surrounding buildings are dense, and the parking demand is large. There are many shortcomings in the city's appearance and residents' parking needs
