Trench excavation depth limiting device and trench excavation method
The invention discloses a trench excavation depth limiting device and a trench excavation method, and relates to the technical field of civil engineering construction machinery. When an excavator bucket consistent with the section of the trench is used for excavation operation, the excavation depth of the trench is not easy to control, a trench excavation depth limiting device is connected to the excavator bucket, symmetrically arranged on the two sides of the excavator bucket and located in the same plane, the distance between the plane and the bottom face of the excavator bucket in the working process is consistent with the trench design depth, resistance generated by contact between the limiting device and the ground when the excavator bucket works prevents the excavator bucket from cutting downwards continuously, it is ensured that the trench depth meets the design requirement, and the trench excavation depth limiting device and the trench excavation method are generally used for trench excavation when the bucket section is consistent with the trench section.
沟槽开挖深度限制装置及沟槽开挖方法，涉及土木工程施工机械技术领域；使用和沟槽截面一致的挖斗进行开挖作业时，沟槽开挖深度不易控制；通过使用沟槽开挖深度限制装置和挖斗连接，对称布置在挖斗两侧，且在同一平面内，该平面和挖斗工作时的底面间距和沟槽设计深度一致。限制装置在挖斗工作时和地面接触产生的阻力阻止挖斗继续下切，确保沟槽深度满足设计要求；通常用于挖斗截面和沟槽截面一致时的沟槽开挖。
