Description
Technical Field
The utility model relates to the field of foundation pit supporting model experiments, in particular to a novel soil nailing wall foundation pit supporting structure adopting bamboo chips.
Background
With the rapid development of the economy in China, the construction industry also steps into the road of the rapid development, however, engineers face a plurality of problems and challenges in the construction process of buildings. If the pit wall after excavation is not subjected to certain supporting treatment in the foundation excavation process, collapse is easily generated under the influence of time and force, so that unnecessary engineering accidents are caused. Currently, in order to solve the problem of pit wall collapse, a plurality of solutions exist, wherein soil nailing walls are favored by a large number of designers as a supporting mode with simple construction. The current soil nailing wall adopts a steel pipe soil nailing mode to construct a temporary support structure, however, backfilling treatment is needed after the foundation pit construction is finished, and a large amount of steel bars and the like can be buried underground in the process, so that unnecessary waste is caused. In the south of China, moso bamboos are produced in abundance, and especially the county of Shangrou in Jiangxi provinces is the reputation of 'the county of moso bamboos', so that the moso bamboos are selected as soil nail materials from the aspects of engineering economy and environmental protection. However, the moso bamboo selected in the engineering has certain requirements, such as length, diameter and the like, which need to meet the design requirements, so that bamboo chips can be selected as substitutes. Compared with the complete moso bamboo, the bamboo chips have the advantages of lower manufacturing cost, stronger plasticity, easier lap joint mode and the like, so the bamboo chips are selected to replace the reinforcing steel bars as the main materials of the soil nails.
Based on the reasons, the utility model designs a novel soil nailing wall foundation pit supporting structure adopting bamboo chips, which reduces the engineering cost and reduces the influence of soil nailing on the surrounding environment on the premise of ensuring the stability of the foundation pit.
Disclosure of Invention
The utility model aims to provide a novel soil nail wall foundation pit supporting structure adopting bamboo chips, which reduces engineering cost and reduces influence on surrounding environment on the premise of ensuring stability of a foundation pit by improving the existing soil nail supporting structure.
In order to achieve the purpose of the utility model, the technical scheme adopted by the utility model is as follows:
the utility model discloses a novel soil nailing wall foundation pit supporting structure adopting bamboo chips, which comprises bamboo chips, through bolts, nuts, steel gaskets, screw steel bars and steel backing plates, wherein the bamboo chips are fixed through the through bolts, the nuts and the steel gaskets, and the through bolts are crossed and fixed in a cross manner to form a main body structure of the bamboo chip soil nails; the through bolts arranged at the ends of the bamboo chips are connected with the threaded reinforcing steel bars, and the ends of the bamboo chips are fastened to the main body structure of the bamboo chip soil nail through nuts, the threaded reinforcing steel bars and the steel backing plates to form the bamboo chip soil nail.
The surface of the bamboo chip is provided with slurry outlet holes.
The bamboo chips are bound by steel wires to externally bind, longitudinal through bolts are arranged at intervals of 1m, and two ends of each through bolt are bound to the inside by nuts.
The through bolts arranged at the ends of the bamboo chips are connected with the similar through bolts in a welding mode with one side of the threaded reinforcing steel bars close to the inner part; the side, close to the outside, of the twisted steel bar is fixed by a nut, and a steel backing plate is used as a gasket at the end parts of the nut and the bamboo chips.
The utility model has the beneficial effects that:
the utility model solves the problems that the existing soil nailing wall is used as a temporary support structure, and is left in the soil after backfilling to cause waste and influence the surrounding environment; on the basis of the original phyllostachys pubescens soil nailing wall, the bamboo chips are adopted to replace the whole phyllostachys pubescens
The existing device has the problems of steel bar waste and adverse effect on the surrounding environment; the bamboo chips are selected to replace the whole moso bamboo on the basis of the original moso bamboo soil nails, and the binding mode of the inside and the outside of the bamboo chips is improved, and meanwhile, the end fixing structure is improved, so that the construction cost is reduced and the surrounding environment is not greatly influenced on the premise of ensuring the stability of foundation pit support.
