Composite side slope reinforcing structure

Abstract

The invention provides a composite side slope reinforcing structure. The reinforcing structure comprises supporting seepage ditches which are obliquely and longitudinally arranged along a side slope at intervals, and the supporting seepage ditches are defined by the following structures: an upper ditch surface which is obliquely and longitudinally arranged along the side slope, concrete flowing water surfaces which are arranged in a step shape below the upper ditch surface, a rear inverted filter layer which is connected between two adjacent concrete flowing water surfaces, and side inverted filter layers which are arranged on two sides of the concrete flowing water surfaces and are connected with the upper ditch surface; the hollow structure of each supporting seepage ditch is filled with dry masonry rubbles, a plurality of anchor cable hole steel pipes are embedded inwards in the supporting seepage ditches from the upper ditch surface, anchor cables are installed in the anchor cable hole steel pipes, and the ends of the anchor cables are fixed through anchor piers arranged on the upper ditch surface; and blind ditches communicating with the supporting seepage ditches are formed in the bottoms of the supporting seepage ditches, and the blind ditches are perpendicular to the supporting seepage ditches and are transversely arranged. The problem of water-rich soft soil landslide treatment under special terrain and geological conditions is effectively solved, the construction risk is low, and the structure has application and popularization value.

Description

technical field [0001] The invention relates to geotechnical side slope engineering, in particular to a side slope reinforcement structure of composite prestressed anchor cable + supporting seepage ditch + blind ditch. Background technique [0002] With the increase of earth and stone excavation projects of various types of infrastructure, some landslide disasters will inevitably be induced during the construction process, and the treatment usually adopts solutions such as clearing the square and setting anti-slide piles at the front edge. For engineering landslides caused by weak layers with low shear strength, high water content, and large thickness encountered during earthwork excavation, the conventional treatment plan has the following difficulties: (1) Under specific terrain conditions such as landslide rear edge mountain (2) Qingfang will generate a new weak layer free surface, which will lead to the reshaping of the sliding surface to form a new landslide; (3) Under ...
