Description

Technical Field

[0001] The present invention relates to the technical field of underground space construction, and particularly to an underground intelligent parking lot and a construction method thereof. Background Art

[0002] In the prior art, the shortage of parking spaces in major cities has led to an increasingly strong demand for underground parking lots. Conventional underground garages use the open cut method, combining the basement of a building as a parking area, or are independent underground multi-storey parking garages.

[0003] However, the prior art usually uses the open cut method for construction. The open cut garage is limited by both the plane excavation range and economic rationality. Therefore, usually only one to three floors can be built, and when the site conditions are insufficient, the number of parking spaces is relatively limited.

[0004] Therefore, how to increase the number of parking spaces while reducing the environmental impact of open cut has become an urgent technical problem for those skilled in the art. Summary of the Invention

[0005] In view of the above-mentioned defects of the prior art, the present invention provides an underground intelligent parking lot and a construction method thereof. The purpose is to realize the construction of an underground garage by means of an underground shaft and a shield tunnel based on the relevant technologies of underground shafts and shield tunnels, and reduce the limitation of the number of underground floors of the open cut method.

[0006] To achieve the above purpose, the present invention discloses an underground intelligent parking lot, including a car retrieval well, a car storage well arranged underground around an existing building, and a parking garage with more than three floors.

[0007] Wherein, both the car retrieval well and the car storage well are deep shafts, and both are connected to each floor of the parking garage;

[0008] Each floor of the parking garage is an annular underground circular tunnel, and each underground circular tunnel is divided into upper and lower car storage areas by a floor slab, and each car storage area includes at least two lanes;

[0009] Among the two or more lanes in each car storage area, there are at least one driving lane and one parking lane.

[0010] The present invention also provides a construction method for the underground intelligent parking lot, and the steps are as follows:

[0011] Step 1: Locate the car retrieval well and the car storage well, and construct the two deep shafts of the car retrieval well and the car storage well by the VSM method of the shaft tunneling machine technology;

[0012] Step 2: After the construction of the two deep shafts is completed, install a shield in one of the deep shafts as the launching shaft, and then drive along the designed route to the other deep shaft for reception, or return to the launching shaft for reception after passing through the other deep shaft, so as to form a shield tunnel for each floor of the parking garage.

[0013] Step 3: Construct each floor of the parking garage sequentially from bottom to top according to Step 2.

[0014] Step 4: Construct the connection between each shield tunnel of each floor and the two deep shafts to complete the through work of the main structure.

[0015] Step 5: Construct each parking area and each lane of each floor of the parking garage to complete the civil engineering structure.

[0016] Preferably, each floor of the parking garage is assembled with reinforced concrete segments.

[0017] Preferably, supporting facilities are set up after the civil engineering structure is completed; the supporting facilities include an electromechanical system, drainage and fire protection facilities, and a vehicle parking and retrieval platform.

[0018] The application of the present invention can maximize the utilization of underground space resources, construct a large-scale underground parking lot through the shield method, will not damage existing buildings, and can also make it more convenient to park and retrieve vehicles.

[0019] The application of the present invention can reduce the environmental impact caused by constructing a garage by the open cut method and can provide more parking spaces.

[0020] When the present invention is applied to existing buildings, it can be added with less impact, that is, expand the garage.

[0021] The double deep shaft structure of the vehicle retrieval shaft and the vehicle storage shaft in the present invention can relieve the congestion of the exit and the entrance, and significantly improve the parking quantity and throughput capacity compared with an independent garage.

[0022] The following will further illustrate the concept, specific structure and technical effects generated by the present invention with reference to the drawings, so as to fully understand the purpose, features and effects of the present invention. Brief Description of the Drawings

[0026] Embodiment

[0027] As Figures 1 to 3 shown, the underground intelligent parking lot includes a car retrieval shaft, a car storage shaft arranged underground around the existing building, and a parking garage with three or more floors.

[0028] Among them, both the car retrieval shaft and the car storage shaft are deep vertical shafts, and both are connected to each floor of the parking garage;

[0029] Each floor of the parking garage is an annular underground circular tunnel. Each underground circular tunnel is divided into upper and lower car storage areas by a floor slab. Each car storage area includes at least two lanes;

[0030] Among the two or more lanes in each car storage area, there are at least one driving lane and one car storage lane.

[0031] The principle of the present invention is as follows:

[0032] In this invention, the parking area is formed by open-cut deep vertical shafts and multi-layer shield-driven underground tunnels. It can reduce the limitation of the open-cut method on the number of underground floors, provide more parking spaces, and reduce the environmental impact of open-cut.

[0033] Moreover, the double deep vertical shaft structure of the car retrieval shaft and the car storage shaft can greatly reduce the probability of traffic jams at the entrances and exits of multi-layer parking garages.

[0034] In practical applications, the present invention can be applied to the situation where the garage area under the existing building is insufficient. By setting two deep vertical shafts underground around the existing building, and then building multi-layer shield tunnels around the existing building through the shield tunnels between the two deep vertical shafts to form a new underground garage, the number of parking spaces can be increased without affecting the original garage and without affecting the safety of the main building.

[0035] The present invention also provides a construction method for the underground intelligent parking lot, and the steps are as follows:

[0036] Step 1: Locate the car retrieval shaft and the car storage shaft, and use the VSM method and the sinking shaft tunneling machine technology to build the two deep vertical shafts of the car retrieval shaft and the car storage shaft;

[0037] Step 2: After completing the construction of the two deep vertical shafts, install a shield in one of the deep vertical shafts as the launching shaft, and then tunnel according to the designed route to the other deep vertical shaft for reception, or return to the launching shaft for reception after passing through the other deep vertical shaft, to form the shield tunnel for each floor of the parking garage;

[0038] Step 3: Build each floor of the parking garage sequentially from bottom to top according to Step 2;

[0039] Step 4: Construct the connection between each layer of the shield tunnel and the two deep shafts to complete the penetration of the main structure.

[0040] Step 5: Construct each vehicle storage area and each lane of each parking garage on each layer to complete the civil engineering structure.

[0041] In some embodiments, each layer of the parking garage is assembled with reinforced concrete segments.

[0042] In some embodiments, ancillary facilities are installed after the completion of the civil engineering structure; the ancillary facilities include an electromechanical system, drainage and fire protection facilities, and a vehicle pick-up and drop-off platform.

[0043] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention through logical analysis, reasoning, or limited experiments based on the concept of the present invention on the basis of the prior art shall fall within the protection scope determined by the claims.
