One-time Excavation and Forming Construction Method of Trench

Abstract

The invention relates to a construction method for one-time excavation and forming of a trench, which includes the following steps: step 1: installing an assembled height-adjustable guide edge beam on both sides of the trench to be excavated; step 2: turning the height adjustment bolt to adjust the height of the adjustment beam, Make the horizontal slope of the adjusting beam consistent with the slope of the bottom of the trench; Step 3: Excavate the trench with an integral tooth bucket; Step 4: Use the shaped unit temporary support for the trench wall to temporarily support the side wall of the trench; Step 5: Cover the trench with a diversion canopy. The beneficial effects of the present invention are: the assembled height-adjustable guide side beam can adjust the height of the adjustable beam through the height-adjusting screw rod, offset the ground height difference and control the slope of trench excavation; The support pulley and horizontal limit pulley can excavate the trench along the path and slope set by the assembled level-adjustable guide beam, which greatly reduces the difficulty of excavation and improves the construction quality and efficiency of trench excavation.

Description

technical field [0001] The invention relates to the field of drainage side ditch construction, in particular to a construction method for one-time excavation and forming of a ditch. Background technique [0002] The traditional way of trench excavation of road drainage side ditches is mainly carried out with excavator excavation and manual auxiliary correction. However, in this construction method, excavator excavation accuracy is not high, and there are often cases of over-excavation or under-excavation. , although the excavation accuracy in a small area can be well controlled manually, it is difficult to ensure the overall line shape and slope during the excavation process, and the construction period is long, the efficiency is low, and the labor cost is high. After the excavation is completed, due to the untimely pouring of concrete, the excavated trenches often collapse and are soaked by rainwater. The above problems often lead to the difficulty in guaranteeing the cons...
