AI Technical Summary

Technical Problem

The existing drainage ditches on both sides of the ramps at the entrance and exit of the underground parking garage are difficult for workers to clean up due to their special location. Long-term garbage accumulation has caused blockages in the pipes, resulting in slow drainage during heavy rain and causing water backflow and flooding.

Method used

An underground intercepting ditch was designed, comprising a ditch frame, baffles, adjusting plates, a motor-driven dredging plate, and a dredging frame. The size of the drainage ditch opening is adjusted by the adjusting plates, the motor-driven dredging plate clears foreign objects, and the dredging frame expands the dredging range to prevent garbage accumulation and optimize drainage.

Benefits of technology

It effectively prevents garbage accumulation, adjusts drainage volume, ensures that drainage speed matches rainfall intensity, avoids backflow of water, and improves drainage efficiency and ease of cleaning.

Abstract

This utility model relates to the field of drainage facility technology and is a drainage interception ditch for underground structures. It includes a drainage ditch frame with multiple baffles movably inserted inside. A pair of drainage channels are formed on the top of each baffle, and an adjustment channel is formed on the inner wall of the drainage channel. A pair of adjustment plates are movably inserted inside the adjustment channel. In use, the distance between the pair of adjustment plates can be adjusted by adjusting the depth of the adjustment plates into the drainage channel, thereby adjusting the size of the water inlet space for rainwater to enter the drainage channel. This allows personnel to adjust the size of the drainage mechanism according to the drainage volume, ensuring that no garbage or other debris enters the ditch during sunny days. Furthermore, it prevents rainwater accumulation and backflow flooding in low-lying areas during heavy rain due to the drainage mechanism being too small and the drainage speed lagging behind the rainfall intensity. During drainage, a clearing plate can be used to clear any foreign objects accumulated in the drainage channel, ensuring that external rainwater smoothly enters the drainage ditch frame.
