The utility model provides a highway subgrade applying accumulation of tunnel waste slag. The outer side face of an original subgrade is provided with at least one step platform extending in the length direction of the original subgrade; the waste slag stacking layer is stacked on the outer side face of the original roadbed, a geogrid corresponding to the step table is arranged in the waste slag stacking layer, one end of the geogrid extends to the step table, and the other end of the geogrid extends to the outer side inclined face of the waste slag stacking layer; the grouting anchor rods are distributed on the waste slag accumulation layer in a plum blossom shape, and the lower ends of the grouting anchor rods extend to the bottom face of the roadbed in the longitudinal direction. The waste slag generated by tunnel construction is used as the roadbed filler, so that the cyclic utilization of resources is realized, the outward transportation cost of the waste slag and the pollution to the environment are reduced, and good economic benefits and environmental benefits are achieved. By arranging the structures such as the step tables, the geogrids, the grouting anchor rods, the rotary excavating piles and the ground beams, the connection strength between the waste slag accumulation layer and the original roadbed is enhanced, and the overall stability and deformation resistance of the roadbed are improved.

The utility model discloses a structure for avoiding well lid sedimentation and belongs to the field of municipal drainage engineering. The structure comprises a shaft, a mortar layer is arranged on the top of the shaft, a cement concrete layer is arranged on the top of the mortar layer, the inner diameter of the mortar layer is smaller than that of the cement concrete layer, and a sleeve is installed on the inner side. The outer wall of the sleeve is attached to the inner wall of each layer, the top walling crib is fixed to the cement concrete layer through high-strength expansion bolts, a pull rod is embedded in the cement concrete layer and inserted into a sleeve clamping groove, the lower portion of the sleeve is fixed to the shaft through expansion bolts, and a rubber ring is arranged on an inner wall step-shaped installation table to install the well lid. And graded broken stones are backfilled within 1m of the periphery of the shaft. According to the structure, the well lid is reliably connected with a shaft and a pavement base layer through the high-strength expansion bolts and the pull rods to form a unified whole, stability is enhanced, differential settlement and abnormal sound are reduced, meanwhile, sealing and damping are achieved through the rubber rings, and durability is improved.

The utility model provides a pipeline laying foundation structure and a water conveying line using the same. Comprising a first-section base layer which is constructed by concrete and used for bearing a first pipe joint, a second-section base layer which is constructed by concrete and used for bearing a second pipe joint, a third-section base layer which is constructed by concrete and used for bearing a third pipe joint, a fourth-section base layer which is constructed by concrete and used for bearing a fourth pipe joint, and a plurality of connecting steel bars, a gap between the second-section foundation layer and the adjacent third-section foundation layer is a first gap, the multiple connecting steel bars are transversely arranged at intervals and stretch across the first gap, and the first gap is filled with a foam plate; the third section of base layer comprises two first base sub-layers; one first foundation layer is a gravel tamping layer, the other first foundation layer is constructed by concrete, or the two first foundation layers are constructed by concrete and are integrally formed. The utility model further provides a water diversion project water conveying line comprising the foundation structure. According to the utility model, the safety and reliability of the pipeline laying foundation structure of the water delivery line of the water diversion project are economically improved.

This invention relates to the field of foundation treatment technology, specifically to an in-situ solidified composite foundation based on the resource utilization of industrial solid waste and its treatment method. It solves the problems of existing foundations, which often use reinforced concrete piles and sheet piles, resulting in high material costs and poor adhesion to the internal solidification layer; and drainage systems that are mostly single vertical drainage systems, leading to low efficiency in draining water accumulated within the foundation and affecting the durability of the foundation treatment. The invention includes a foundation and foundation solidification piles. Multiple foundation solidification piles are evenly distributed along the outer edge of the foundation, and a foundation connecting beam is cast between every two adjacent foundation solidification piles. An outer retaining wall is provided on the outside of the foundation connecting beam. This invention, through the coordination of the foundation connecting beam, outer retaining wall, inner retaining wall, and matching arc plate, utilizes industrial solid waste as aggregate to prepare foundation piles and other components, achieving the resource utilization of industrial solid waste, reducing environmental pollution caused by solid waste accumulation, and simultaneously lowering engineering material costs.
