Abstract

The invention discloses a cut slope angle reference instrument, which comprises a support and a bearing plate. The top of the support is provided with an installation table and is fixedly connected tothe bottom of the installation table. The bottom surface of the bearing plate is provided with a connection part (I). The top surface of the installation table is provided with an installation part (I). The connection part (I) and the installation part (I) are rotatingly connected so that the bearing plate can rotate above the installation table. The installation part (1) is provided with an angle adjusting device (I), which can adjust and lock the rotation angle of the bearing plate. The top surface of the bearing plate is provided with a laser emitter. The rotation plane of laser beams emitted by the laser emitter is parallel to the rotation plate of the bearing plate. The structure of the instrument is simple; the instrument is convenient to use, does not influence the digging positionof a side slope, and provides precise angle reference for digging the side slope; and the side slope digging precision is improved.

Description

technical field [0001] The invention relates to the field of side slope construction, in particular to a grading angle reference instrument. Background technique [0002] In order to prevent landslides and ensure construction safety, when the excavation depth or filling height of excavation or filling exceeds a certain limit, a slope with a certain slope should be formed on its edge. Too small a slope increases costs; too large is unsafe. Therefore, the slope of the slope should be determined according to the actual conditions of excavation depth, soil quality and groundwater, and in accordance with the "Code for Construction and Acceptance of Earthwork and Blasting Engineering". The grading can be placed in a slope, or in a stepped shape according to the construction needs. In common construction operations, after the grading angle of the slope is determined, support rods are inserted at the bottom and top of the slope respectively, and then a grading rope is stretched be...
