Drainage structure at the entrance of the underground garage

Abstract

The invention discloses a drainage structure for the entrance of an underground garage, which comprises a buried part across the road entrance, one end of the top of the buried part is exposed and forms a water inlet cavity, and more than one movable support is arranged side by side in the water inlet cavity There is an installation cavity inside the buried part, and a drawer box is movably installed in the installation cavity. One end of the drawer box is in contact with one of the movable support pieces. The inside of the drawer box has an open accommodation cavity, and the opening of the accommodation cavity On the side away from the movable supporting piece, the drawer is driven by a telescopic drive assembly, and two baffles are also arranged in the installation cavity. The present invention changes the traditional drainage structure by adopting more than one movable support piece arranged side by side, and the whole drainage outlet is closed during daily use, no solid matter such as external dust enters, and the service life of the drainage structure can be increased, and at the same time The invention can also increase the drainage speed in rainy days and improve the drainage efficiency.

Description

technical field [0001] The invention relates to the field of construction, in particular to a drainage structure for an entrance of an underground garage. Background technique [0002] Nowadays, the entrance of the underground garage is a slope, in order to prevent rainwater from pouring into the underground garage in rainy days, a drainage structure is provided at the entrance. The traditional drainage interface is generally intercepted by a water inlet tank. The top of the water inlet tank is covered with a support plate, and a leak hole is opened on the support plate, and the vehicle is supported by the support plate. This structure has disadvantages after long-term use. For example, the vehicle is pressed for a long time The support plate is displaced, or the support plate is broken, and external debris is easy to block the leak hole, requiring regular maintenance. In addition, due to the small diameter of the leak hole, the drainage speed is slow. Even if the drain hol...

Problems solved by technology

The traditional drainage interface is generally intercepted by a water inlet tank. The top of the water inlet tank is covered with a support plate, and a leak hole is opened on the support plate, and the vehicle is supported by the support plate. This structure has disadvantages after long-term use. For example, the vehicle is pressed for a long time The support plate is displaced, or the support plate is broken, and external debris is easy to block the leak hole, requiring regular maintenance

In addition, due to the small diameter of the leak hole, the drainage speed is slow. Even if the drain hole is enlarged, due to the low drainage efficiency of the internal drainage channel, more accumulated water cannot be poured into the water inlet, and a large amount of rainwater will enter along the slope. to the basement, so the efficiency of the current drainage structure is low, and there are many deficiencies in it
