Background

With the continuous improvement of the living standard of people, more and more people buy private cars; playing a significant role in urban traffic and environment. And the problem of difficult parking is solved, and huge business opportunities and wide markets are brought to the mechanical parking equipment industry. When the business opportunity and the competition coexist, the mechanical parking equipment industry in China also enters a stable development stage from a rapid development stage. The market is huge in the future, but the demand for products will develop towards two extremes: one extreme is the extreme of price, the market needs a large amount of low-price mechanical parking equipment, the most basic service performance can be ensured as long as the purpose of increasing parking spaces can be achieved, the market is occupied by price advantages, and the market share of the part is expected to reach 70% -80%; the other extreme is the extreme of technology and performance, and the parking equipment is required to have excellent service performance, convenient operation mode and fast access speed. Through the summary of the use experience of the mechanical parking equipment at home and abroad, people can find that the first pursuit of the speed, the waiting time and the convenience degree of vehicle access when the mechanical parking equipment is used for vehicle access. In addition, in the future mechanical parking equipment market, more attention is paid to a perfect after-sale service system, and a remote monitoring system and a remote fault guide processing system are targets pursued by users. With the continuous and rapid development of economy in China and the improvement of urban planning, the mechanical parking equipment industry becomes a living and active sunrise industry, and the technology of the mechanical parking equipment is greatly developed.

Nowadays, with rapid development of economy, ground buildings and greening are gradually increased, so that parking spaces on the ground are seriously insufficient, and therefore, an underground stereo garage becomes a development trend, and how to construct the underground stereo garage is also a subject of consistent research of technical personnel in the field.

For example, in the engineering method of a prefabricated and spliced sinking-well type parking garage disclosed in the invention patent with the application number of 2017100964937, the sinking-well structure comprises a bottom-layer blade-foot layer and a plurality of standard layers above the bottom-layer blade-foot layer, the installation precision of the blade-foot layer determines the assembly quality of an upper-layer sinking-well standard layer, and the construction method of the blade-foot layer comprises the following steps: the method for vertically placing the blade foot blocks comprises the steps that the blade foot blocks are vertically placed, and are sequentially spliced to form a first layer of a shaft (the lower portion of the inner wall of each blade foot block is downwards inclined to be connected with the outer wall to form a wedge-shaped cross section), the blade foot blocks are supported through a support frame, a positioning limiter and an inclined strut, the support frame, the positioning limiter and the inclined strut are disassembled after one blade foot block is installed, the construction method adopts a prefabricated blade foot structure, and the construction method is large in size, high in cost and difficult to guarantee splicing seam accuracy and waterproof in the later period of the solid section of each blade foot, and two times or three times are needed for transportation, hoisting and turnover due to the fact that components are of special-shaped structures.

For another example, in the slip form member and the open caisson cutting edge foot layer slip form construction method using the same disclosed in the invention patent with the application number of 201711007754.X, a slip form member is disclosed, which comprises a slideway, an outer template, an inner template, two side templates and a plurality of connecting and fixing members, wherein the slideway is provided with a plurality of chutes for mounting the outer template and the inner template, the bottom of the outer template is provided with a plurality of outer support legs, the outer support legs are arranged on the outer side of the slideway and move along the chutes, the bottom of the inner template is provided with a plurality of inner support legs, the inner support legs are arranged on the inner side of the slideway and move along the chutes, and the side templates are arranged on two side edges of the inner template and the outer template and connected with the inner template and the outer template through the connecting and fixing members. Although the linear vertical precision is ensured after the blade foot construction is finished so as to ensure the assembly quality of the upper open caisson standard segment, the construction period is long due to cast-in-place, the construction period of the stereo garage is seriously influenced, and the waterproof performance of the bottom and the side wall is difficult due to the measure.

The prefabricated members or the pouring members are not high in structural strength, are easy to damage in construction, and are limited in service life, the friction resistance is large during open caisson construction, so that a difficult settling shaft is deviated, and the prefabricated members or the pouring members are deformed due to the pressure of an outer soil layer in the construction process, so that the inner diameter of an underground wall body is influenced, the installation size is inaccurate, and the normal use of the stereo garage is influenced.
