Problems solved by technology
When the traditional drainage ditch floating soil and slope are repaired, because the slope cannot be seen through, it is necessary to set measuring points on both sides of the slope every 1m~2m, hang the measuring line and then carry out the slope repair. During the repair process, the measuring points, Laying out, time-consuming, labor-intensive, repetitive process, low work efficiency, long service life of measuring instruments, large number of personnel, high labor and equipment costs

The invention relates to a construction method of a mortar rubble drainage ditch and a groove slope trimming measuring and positioning tool. The groove slope trimming measurement and positioning toolmainly includes a supporting frame, supporting legs, a connecting plate and the like, and the supporting frame includes a cross bar, vertical bars and a reinforcing bar; the cross bar is parallel to the ground, the vertical bars are perpendicular to the cross bar and symmetrically arranged on both sides of the cross bar; the two ends of the reinforcing bar are correspondingly connected with the vertical bars; one ends of the supporting legs are connected with the tail ends of the vertical bars, and the other ends of the supporting legs face vertically downwards; and one end of the connecting plate is connected with the tail end of the cross bar, and the other end of the connecting plate is connected with the vertical bar on the same side, and the connecting plate is evenly provided with thread hanging holes and threaded holes. The construction method of the mortar rubble drainage ditch mainly includes the steps that (1), the groove slope trimming measuring and positioning tool as claimed in claim 1 is assembled; (2), color thread hanging ropes are bonded to the thread hanging holes 7 with different specifications; (3), the groove slope trimming measuring and positioning tool bondedwith the thread hanging ropes is inserted into a soil layer at an interval of 10-15m; and (4), according to the rope position, construction is carried out.
Description
Technical field: [0001] The invention relates to the technical field of drainage ditch construction for highway and municipal road engineering, in particular to a construction method for a masonry rubble drainage ditch and a tool for measuring and positioning groove side slope trimming. Background technique: [0002] With the development of social economy, in order to meet the drainage requirements of expressways and municipal road projects, drainage ditches are generally provided on both sides of the road. According to different functions and requirements, drainage ditches include various types of drainage ditches such as soil side ditch drainage ditches, masonry stone drainage ditches, and reinforced concrete drainage ditches. According to different structural forms, the drainage ditch includes different cross-sectional forms such as inverted trapezoidal, rectangular, and square, and the cross-sectional size generally ranges from 40cm to 200cm. After the earth excavation ...
