Method of stone recycling in rock foundation pit excavation

Abstract

The invention relates to a method of stone recycling in rock foundation pit excavation. First, a hard rock mass is broken by adopting a static crushing and blasting technology, and then a completely weathered rock block is selected to be directly used in temporary road and foundation pit backfilling; and the moderately weathered and over moderately weathered rock block is repeatedly decomposed andscreened by a on-site crusher to obtain the gravel meeting the grading requirements for concrete preparation, and transported to a concrete mixing plant as raw materials for concrete preparation, andfinally, the prepared concrete is still transported back to the original construction site for foundation and structure construction. By means of the method of stone recycling, the construction siteresources can be fully used for self recycling, and the environmental pollution due to the waste earth and stone outward transportation is avoided; and the formed available resources can not only meetthe use of the original project, but also the rest of the available resources can be used for other projects, the project benefits are greatly improved, and the method of stone recycling is especially suitable for the construction of the rock foundation pit and is of great benefit for the implementation of the green construction of the project.

Description

technical field [0001] The invention relates to a method for utilizing stonework in a hard rock foundation pit, in particular to a method for self-recycling stonework used in the excavation and construction of rocky foundation pits. Background technique [0002] At present, in the excavation and construction of hard rock foundation pits, because the excavation of rock foundation pits requires extensive crushing of soil layers, a large number of rocks and gravels need to be transported and discarded. On the one hand, it has brought huge construction pressure to earth and stone transportation. , On the other hand, gravel and stones cannot be effectively utilized, and a large amount of outbound piles have seriously affected the surrounding environment, which runs counter to the current green construction. Contents of the invention [0003] The purpose of the present invention is to provide a method for recycling stonework in rocky foundation pit excavation, aiming at the pres...
