Description
Technical Field
The invention belongs to the field of underground garages and construction thereof, and particularly relates to a bin type ultra-deep underground three-dimensional intelligent garage and a construction method thereof.
Background
With the economic growth and the acceleration of urbanization process, the problem of difficult parking in cities is increasingly prominent, and particularly in the central zone of the city, "difficult parking" becomes a new trouble of urban life, and the price of urban parking spaces is increased by times. At present, the rigidity requirement of about 2000 ten thousand parking spaces exists in China every year. But the available ground space in cities is less and less, and the contradiction between the urban development and the land resource shortage is more prominent. Especially, the available field in the downtown area is narrow and small, if a common ground parking garage or an underground parking garage is built, the number of the parking spaces which can be provided after the lane and the like are removed is limited, the utilization efficiency of the land is low, and the cost of a single parking space is very high. The invention is a high-efficiency and economic underground garage and a construction method thereof, and has great significance.
Disclosure of Invention
The invention aims to provide a bin type ultra-deep underground three-dimensional intelligent garage and a construction method thereof, aiming at the defects in the prior art, the number of parking spaces is greatly increased (the parking efficiency is improved by more than 15 times compared with the conventional underground parking garage) through ultra-deep and standardized parking bin design, and the land utilization efficiency and the economy are greatly improved.
In order to solve the technical problems, the following technical scheme is adopted:
the utility model provides a three-dimensional intelligent garage in storehouse formula ultra-deep underground which characterized in that: the underground garage consists of one or more standard cabins and comprises a single-cabin underground garage, a double-cabin underground garage and a six-cabin underground garage, wherein the six-cabin underground garage expands towards two sides to form a multi-cabin underground garage with a larger plane area.
Furthermore, the standard cabin is composed of a parking space, a PCS type intelligent three-dimensional parking lifting system, an air exhaust shaft, and matched fire-fighting equipment and an electromechanical control system. The standard bins of the underground garage are provided with independent upper and lower channels and a control system, and can operate independently. PCS type intelligent three-dimensional parking lifting system is very convenient to send cars to parking spaces in an automatic mode. The ventilation problem of underground garage is solved to the well of airing exhaust, guarantees that the air is unblocked, maintains the comfortable air circumstance in the car.
Further, this underground garage is including the outer wall of outermost periphery and inboard interior welt wall, and the outer wall is formed by two unifications of foundation ditch retaining wall and garage outer wall, and the underground garage of duplex storehouse sets up a supporting beam with the underground garage that ally oneself with the storehouse more, and a supporting beam from top to bottom is even sets up, and a supporting beam's outer end connection welt wall separates into a plurality of standard storehouses with underground garage with the help of a supporting beam. The bottom of the foundation pit supporting wall generally enters a lower hard soil layer or bedrock so as to ensure the stability of foundation pit excavation and simultaneously cut off underground water. The foundation pit supporting wall works independently in the foundation pit excavation stage, after the foundation slab is completed, the garage outer wall is additionally arranged on the inner side of the foundation pit supporting wall, and the foundation pit supporting wall and the garage outer wall work cooperatively to meet the requirements in the permanent use stage. The interior lining wall may simplify a brick wall or a thinner reinforced concrete wall. The support beam does not influence the parking and lifting of the vehicle in the bin. And the supporting beams are constructed layer by layer from top to bottom in the excavation stage of the foundation pit. The foundation pit is not dismantled after construction, and is used as a permanent structure.
Further, the foundation pit supporting wall is one or a combination of a plurality of cast-in-place piles, concrete precast piles, steel piles, piles in an SMW construction method and underground continuous walls.
