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 further described in detail below in conjunction with the drawings.
[0041] Such as figure 1 As shown, an earth excavation construction method includes 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 to a depth of 0.5 meters less than the design depth. The remaining depth is manually excavated, and the final depth is controlled to a depth of 0.2 meters less than the design depth, thereby forming a preliminary excavation Pit, the diameter of the first excavated pit is controlled at 2 meters;
[0045] S4. Marking depth: such ...

The invention discloses an earth excavation construction method which comprises the following steps of S1, surface soil cleaning; S2, measuring and positioning; S3, preliminary excavation: the groundis excavated with an excavator, an excavating depth is controlled at a depth of 0.5m smaller than a designed depth, a remaining depth is manually excavated, a final depth is controlled at a depth of 0.2m smaller than the designed depth, a primary dug pit is formed, and the diameter of the primary dug pit is controlled to be 2m; S4, depth marking: excavation auxiliary equipment is introduced and emits light to mark the inner side wall of the primary dug pit; S5, comprehensive excavation: the excavator is used for performing excavation from the inner side wall of the primary dug pit towards theperiphery, and the excavation auxiliary equipment is provided with a remote monitoring module used for helping an excavator operator to observe the inner side wall of the primary dug pit; S6, tail endexcavation: the residual depth of 0.2m at the bottom of a foundation trench is manually excavated; and S7, foundation trench cleaning. The earth excavation construction method has the following advantages and effects that the construction method reduces the overexcavation phenomenon of the excavator and is beneficial to smooth construction of the water conservancy construction engineering.
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, earth excavation is an important step, and the main purpose is to form the foundation trench and trench in the water conservancy project. Earthwork excavation mainly includes processes such as loosening, crushing, digging and loading, transportation and slag removal. In small water conservancy projects, earthwork excavation is usually divided into manual and semi-mechanized excavation, using simple tools such as spade picks, pneumatic picks, and pneumatic drills. Lifting or simple and small transportation tools are used for operations; and for some large and medium-sized water conservancy projects, excavators and other machinery are used for earth and rock excavation. [0003] The current earth excavation construction method is mainly to use an excavator to di...
