Title: The safty construction method of the side ditch using the hardening agent
Inventor: KIM GUN
IPC: E02B5/02
Filed: 2019-10-13
Abstract: The present invention relates to a construction method of all types of side ditches including side ditches on hill tops for addressing problems which have occurred so far, and fundamentally removing causes for deformations occurring after construction, so that the side ditches can serve as a semipermanent structure. The major causes for deformation of side ditches are due to insufficient tempering which unavoidably occurs because of small space for refilling on a duct lower surface unit and a side surface unit. In addition, the causes include the generation of a joint unit due to great differences in the physical characteristics between a duct and soil and sand. Such causes deform the soil and sand of the lower sides of side ditches and side surface units, cause erosion on lands near the structure, and generate deformations of side ditches and destructions of slopes. Accordingly, the present invention aims to provide a construction method which uses all kinds of hardening agents which can harden soil and sand, and refills the lower surfaces and side surfaces of ducts, thereby preventing subsidence and erosion causing poor construction, and forming a succession section between ducts and soil and sand. Accordingly, the method is able to minimize the impacts of joint units and the penetrating water volume. Such series of acts provide not only greater stability of side ditches than those of the conventional methods but also a far faster construction. Even the range of construction is remarkably reduced from the concrete side ditches placed on the site, thereby minimizing damage to nature. In addition, the method remarkably reduces the causes for destroying slopes as well.
