However, the cast-in-place reinforced concrete structure also has many shortcomings such as self-heaviness, poor crack resistance, poor heat and sound insulation performance, and environmental pollution during construction. The anti-floating stability problem of the basement after the groundwater rises and the surface water is poured into the foundation pit
This will inevitably delay the construction period and increase the cost

Abstract
The invention discloses an assembled integral type basement structure and a quick and safe construction method thereof. The quick and safe construction method comprises the steps that a plain concretecushion layer is arranged on a preset foundation, and a waterproof roll is paved; prefabricated bottom plates are installed on the waterproof roll; the prefabricated bottom plates are connected in the longitudinal direction and in the transverse direction; the prefabricated bottom plates on the outer edge are connected with a prefabricated outer wall; a basement prefabricated top plate beam is connected with a cast-in-place concrete column; a basement prefabricated top plate is connected with the basement prefabricated top plate beam; and a concrete lamination layer is cast in place on one side after prefabricated component joints are connected. According to the assembled integral type basement structure and the quick and safe construction method thereof, quick and safe construction can be achieved through prefabricated components in the basement construction process, therefore, large sums of money can be saved, and the construction period can be shortened; meanwhile, inner and outerhydraulic equilibrium of a basement is achieved through holes reserved in the plate faces of the prefabricated bottom plates and the wall face of the prefabricated wall, and the anti-floating stability requirements of the basement are met under the extreme conditions in the construction period; and construction of the prefabricated component lamination layer is completed timely, and the waterproofand anti-leakage requirements of the basement in the using period are met.
Description
technical field [0001] The invention relates to the field of civil engineering, in particular to an assembled integral basement structure and a safe and rapid construction method thereof. Background technique [0002] With the further deepening of reform and opening up in the past ten years, the leapfrog development of my country's economy has driven the urbanization process. The acceleration of urbanization has also brought about a series of problems, such as "urban diseases" such as dense urban population, deteriorating traffic, and environmental pollution. In order to solve the above-mentioned problems in the process of urbanization, large-scale development and utilization of underground space has become an inevitable problem for urban decision-makers. [0003] The attached basement of civil buildings is one of the main directions of vigorous development in the urban construction of our country at present. Since the basement is entirely or partially buried in rock and s...
