Problems solved by technology
[0003] The current earth excavation construction method is mainly to use the excavator to dig the foundation trench directly according to the construction drawing. The depth of the foundation trench is mainly controlled by the operator of the excavator. However, in many construction projects, the depth of the foundation trench is very important , if the operator of the excavator is not sure of the size, it is easy to over-excavate the foundation trench, and even damage the soil structure at the bottom of the foundation trench in severe cases, and groundwater gushing occurs, which will take extra time to deal with and slow down the entire water conservancy construction Project duration

Embodiment Construction
[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0041] Such as figure 1 Shown, a kind of earth excavation construction method comprises the following steps:
[0042] S1. Surface soil cleaning: Clean up the vegetation, garbage and obstacles in the excavation area, try to keep the original timber trees, and the timber trees that really need to be felled must have special instructions from the supervisor or the owner;
[0043] S2. Measure and locate, determine the excavation area and excavation depth;
[0044] S3. Preliminary excavation: use an excavator to excavate the ground, the excavation depth is controlled at a depth 0.5 meters smaller than the design depth, the remaining depth is excavated manually, and the final depth is controlled at a depth 0.2 meters smaller than the design depth, thus forming the initial excavation Pit, the diameter of the first excavated pit is controlled at 2 meters;

The invention discloses an earthwork excavation construction method, which comprises the following steps: S1. surface soil cleaning; S2. measurement and positioning; S3. preliminary excavation: using an excavator to excavate the ground, and the excavation depth is controlled to be 0.5 meters smaller than the design depth. Depth, the remaining depth is manually excavated, and the final depth is controlled at a depth 0.2 meters smaller than the design depth to form an initial excavation pit, and the diameter of the initial excavation pit is controlled at 2 meters; S4. Depth of marking: introduction of excavation auxiliary equipment, The excavation auxiliary equipment emits lights to mark the inner wall of the initial excavation pit; S5. Comprehensive excavation: use the excavator to excavate from the inner wall of the initial excavation pit towards the surroundings, and the excavation auxiliary equipment is provided with a function to help the excavator operator observe the inner side of the initial excavation pit. The remote monitoring module of the wall; S6. Excavation at the end: manual excavation of the depth of 0.2 meters remaining at the bottom of the foundation trench; S7. Cleaning the foundation trench. The invention has the following advantages and effects: the construction method reduces the phenomenon of overdigging by excavators, and is beneficial to the smooth progress of water conservancy construction projects.
Description
technical field [0001] The invention relates to the field of water conservancy construction, in particular to an earth excavation construction method. Background technique [0002] In water conservancy construction projects, earthwork excavation construction is an important step, the main purpose is to form foundation trenches and channels in water conservancy projects. Earthwork excavation mainly includes loosening, crushing, digging, transporting slag and other processes. In small water conservancy projects, earthwork excavation is usually divided into manual and semi-mechanized excavation. Simple tools such as shovel picks, pneumatic picks, and pneumatic drills are used. Lifting or simple and small transportation tools are used for operations; and some large and medium-sized water conservancy projects are excavated with excavators and other machinery. [0003] The current earth excavation construction method is mainly to use the excavator to dig the foundation trench dir...
