AI Technical Summary

Technical Problem

In existing diaphragm wall construction, traditional wall brushes are ineffective at removing stubborn sediment from the bottom of the trench, especially in clay and composite soil layers, which affects construction quality and efficiency.

Method used

Design a deep wall brushing device based on dual-wheel milling, including a back plate, a cutting structure and a spraying structure. The device uses a cutting plate and high-pressure mud to clean the sediment at the bottom of the tank section. Large mud blocks are scraped off by the cutting plate and the sediment is crushed by high-pressure mud. Different types of wall brushers are used to clean different soil types.

Benefits of technology

It achieves efficient and thorough cleaning of sediment at the bottom of the trench, improves construction efficiency, reduces construction costs, improves the quality of hole cleaning, and has strong applicability, suitable for various geological conditions.

Abstract

The application discloses a deep wall brushing device based on double-wheel milling and a use method thereof, and the device comprises a back plate, a cutting structure and a mortar spraying structure; the back plate is used for mounting the whole wall brushing device; the cutting structure is used for cleaning the sediment, one end of the cutting structure is fixed on the back plate, and bristles are arranged on the cutting structure; the mortar spraying structure is used for spraying high-pressure mortar for cleaning, the mortar spraying structure is located on one side of the back plate, and the other side of the back plate is provided with a mortar inlet pipeline which is used for being connected with the mortar spraying structure. The device can effectively cut and crush the sediment at the bottom of the groove section, can also wash the hard clay or the flow state soil body, and can strip the sediment and the soil body attachments from the reinforcing steel bars or the profiled steel; the device has the advantages of simple structure, convenient use, greatly reduced construction cost, improved construction efficiency, improved hole cleaning quality, reduced construction risk, high applicability, and positive significance for optimizing the diaphragm wall construction.
