AI Technical Summary
Technical Problem
During trench excavation, construction workers need to frequently measure and adjust the trench depth to ensure it meets design requirements, resulting in low construction efficiency and a large workload.
Method used
The device includes a fixed plate, a support plate, a support rod, and a laser level. The laser level forms a horizontal laser mark to guide the excavating equipment to dig a trench that meets the required standard. The height of the laser mark is adjusted by a guide sleeve, a drive gear, and a drive unit to ensure the accuracy of the trench depth.
Benefits of technology
This reduced rework among construction workers, improved the efficiency and accuracy of trench excavation, and reduced the workload of construction workers.

Abstract
本发明属于土方施工技术领域，具体的说是一种沟槽开挖深度限制装置，包括固定板；所述固定板的两端均栓接有支撑板；所述支撑板的底部能够与地面固定；所述固定板的中部竖直设置有支撑杆；多个所述支撑杆首尾串联固接；底部所述支撑杆上设置有多个激光水平仪；将多个支撑杆进行串联固接，支撑杆的底端竖直接触到沟槽的底面，将支撑杆保持竖直状态与固定板固定连接，根据挖掘的需求，将多个激光水平仪均匀的安装固定到支撑杆上，利用激光水平仪发射的水平激光，在待挖掘的沟槽中形成水平的激光标线，从而便于使用人员使用挖掘设备挖掘出合格标准的沟槽，从而减少施工人员对沟槽的返工情况，继而减少了施工人员的工作量，提高了施工的效率。
