AI Technical Summary
Over time, the underground water tanks cause unevenness, damage, and collapse of the road surface, and the cost of repair and replacement is high, and on-site construction is difficult.
A reinforcing structure was added to the existing columns and tie rods. The columns were made of steel pipes filled with concrete, with the bottom connected to the raft foundation and the top connected to the hardened ground, which enhanced the water tank's pressure resistance.
This improves the pressure resistance of underground water tanks, prevents road damage and collapse, and enables underground water tanks to function as both landscaping and parking spaces.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of underground water tanks, and more particularly to an underground water tank structure that allows vehicles to be parked on the ground. Background Technology
[0002] An underground water tank is a device that uses underground space to store water. Compared with traditional above-ground water tanks, it takes up less space, does not obstruct the view, and is more efficient. To ensure the long-term use and safety of the water tank, a pressure-resistant structure is usually installed on the underground water tank. The road surface with underground water tanks can usually only be used as a green belt. Over time, the road surface with underground water tanks will become uneven, damaged and collapsed. Moreover, the cost of repairing and replacing underground water tanks is too high, and the on-site construction is difficult.
[0003] To address this, we propose an underground water tank structure that allows vehicles to be parked on the ground. Utility Model Content
[0004] This utility model provides an underground water tank structure for parking vehicles on the ground.
[0005] The technical solution adopted by this utility model is: an underground water tank structure for parking vehicles on the ground, including a raft foundation, a water tank, columns, tie rods, a reinforcing structure, and a hardened ground. The water tank is provided on the raft foundation, and columns and tie rods are provided inside the water tank. The columns and tie rods are connected by connectors. The reinforcing structure is provided inside the water tank. The bottom of the reinforcing structure passes through the bottom of the water tank and connects to the raft foundation, and the top of the reinforcing structure passes through the top of the water tank and connects to the hardened ground.
[0006] Furthermore, the reinforcing structure consists of several evenly distributed steel pipe columns filled with concrete.
[0007] Furthermore, the hardened ground surface is a concrete structure.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0009] 1. This utility model adds a reinforcing structure to the original columns and tie bars. The reinforcing structure is a steel pipe filled with concrete. The bottom of the reinforcing structure passes through the bottom of the water tank and connects to the raft foundation, and the top of the reinforcing structure passes through the top of the water tank and connects to the hardened concrete ground. This strengthens the water tank's compressive strength, allowing the road surface of the buried water tank to be used not only as a green belt but also for parking vehicles, thus solving the problem of road surface damage and collapse caused by the buried water tank over time.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] like Figure 1-2 As shown, an underground water tank structure for parking vehicles on the ground includes a raft foundation 1, a water tank 2, columns 3, tie rods 4, a reinforcing structure 5, and a hardened ground 6. The water tank 2 is mounted on the raft foundation 1, and the columns 3 and tie rods 4 are installed inside the water tank 2. The columns 3 and tie rods 4 are connected by connectors. The reinforcing structure 5 is installed inside the water tank 2, with its bottom passing through the bottom of the water tank 2 and connecting to the raft foundation 1, and its top passing through the top of the water tank 2 and connecting to the hardened ground 6.
[0015] Furthermore, the reinforcing structure 5 consists of several evenly distributed steel pipe columns filled with concrete.
[0016] Furthermore, the hardened ground surface 6 is a concrete structure.
[0017] Working principle: During use, a water tank 2 is set on the raft foundation 1. Inside the water tank 2, columns 3 and tie rods 4 are installed. The columns 3 and tie rods 4 are connected by connectors. Several evenly distributed column steel pipes are also set inside the water tank 2. The bottom of the column steel pipes passes through the bottom of the water tank 2 and connects to the raft foundation 1. When the ground hardens, concrete is poured into the column steel pipes together and vibrated to compact it, forming the reinforced structure 5 of the water tank.
[0018] Based on the original column 3 and tie rod 4, this utility model adds a reinforcing structure 5, which is a steel pipe filled with concrete. This reinforcing structure 5 enhances the compressive strength of the water tank 2, so that the road surface of the buried water tank can not only be used for green belts, but also for parking vehicles, thus solving the problem of road surface damage and collapse of buried water tanks over time.
[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
