A construction device for opening a building drainage ditch

Abstract

The present invention belongs to the technical field of architectural construction, and particularly relates to a building drainage ditch construction apparatus. The apparatus comprises a strip base provided with a chute; a slide strip is matched in the chute; vertical plates and a first positioning mechanism are mounted on the slide strip; a second positioning mechanism is mounted on the strip base; a rectangular frame is mounted between the vertical plates; two guide rails, a gear and a rotation motor are mounted on the rectangular frame; a rack is mounted on the guide rails; a guide frame is mounted on the rack; a triangular plate is mounted on an output shaft of the rotation motor; a guide column is mounted on the triangular plate; an insertion plate is mounted on the bottom surface ofthe rack; a mounting column is mounted on the bottom surface of the gear; a sleeve is mounted on the mounting column; a stirring plate is mounted on the outer side wall of the sleeve; a horizontal base is mounted at the end portions of the guide rails; and a gathering mechanism is mounted on the horizontal base. By loosening and gathering soil before excavation of ditches, the ditches are guaranteed on the same straight line during excavation, and the side wall levelness of the ditches during excavation can be improved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction device for opening a building drainage ditch. Background technique [0002] Building drainage ditch refers to the ditch that guides the water collected in the low-lying places near the building to the drainage system. The traditional building drainage ditch is first excavated and then poured with concrete on the surface of the trench. As buildings have higher and higher requirements for drainage performance, more and more building drainage ditches use resin or stainless steel finished drainage ditches, that is, first dig out trenches that match the shape of the finished drainage ditch, and then place the finished product Drains are installed into the trench. When excavating trenches, construction personnel usually use shovels to dig. In the actual construction process, manual excavation with shovels is not only inefficient, but also has t...

Problems solved by technology

[0004] The invention provides a construction device for building drainage ditches. The purpose is to solve the following problems in the manual excavation of building drainage ditches with shovels: (1) It is difficult to accurately control the direction of the ditches when manually digging with shovels, and it is impossible to ensure that the ditches are in a single direction. On the straight line, it will have an adverse effect on the stability of the finished drainage ditch after installation; (2) When digging with a shovel manually, due to the viscosity of the soil, there will be a large shear force between the two sides of the shovel and the soil, which is easy to cause The side of the shovel is deformed, and the deformed shovel reduces the flatness of the side wall of the trench during the excavation process, which will also adversely affect the stability of the finished drainage ditch after installation
