Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of excavating equipment, in particular to a dike engineering continuous cutoff wall trenching equipment and trenching method. BACKGROUND

[0002] Dike engineering refers to the water retaining structures built along the edge of rivers, canals, lakes, seashores or flood discharge areas, flood diversion areas or reclamation areas, and is an important part of the flood control system. It works together with large and medium-sized flood control reservoirs, flood detention areas, flood diversion gates and other projects to ensure the safety of plain flood control. For the dike sections with seepage problems, dike body cutoff walls are used for reinforcement, and cutoff wall construction is the key in dike engineering. The cutoff wall, also known as underground continuous wall, is a continuous wall body set below the ground for water interception, seepage prevention, soil retaining and weight bearing. The underground continuous wall is a foundation engineering that uses trenching machinery to excavate a narrow and deep trench along the axis of the deep excavation engineering on the ground. After the trench is cleaned, a steel reinforcement cage is hoisted into the trench, and then the guide pipe method is used to pour concrete to form a single unit trench section. This process is repeated to build a continuous reinforced concrete wall underground, which serves as a water interception, seepage prevention, weight bearing and water retaining structure.

[0003] During the construction of the underground continuous wall, a narrow and deep foundation trench is first excavated underground, usually using a trenching machine. During the self-weight falling stage, the grab body opens to the maximum angle and invades the interior of the soil medium under its own gravity. During the hydraulic closing stage, the grab body realizes the closing process under the action of the hydraulic closing torque and completes the grabbing of the working medium, and then it is lifted and transferred to the transport vehicle. However, the existing trenching machine needs to be lifted and released once for every grab to transfer the soil in the grab to the transport vehicle, and this process is repeated. The speed and inclination of each lifting and lowering need to be controlled, and it cannot be too fast. This results in low efficiency of grab trenching and cleaning, and slow construction progress. Therefore, the present application proposes a dike engineering continuous cutoff wall trenching equipment to solve the above-mentioned technical problems and provide a new technical solution.
