Hot rolling plant plate zone extra-large deep foundation pit group construction technological process design method

Abstract

The invention discloses a hot rolling plant plate zone extra-large deep foundation pit group construction technological process design method. The method comprises the steps of determining an excavation design thought; determining a supporting form; designing construction procedures; compiling an emergency plan; excavating deep foundation pits. According to the hot rolling plant plate zone extra-large deep foundation pit group construction technological process design method, the whole process including the excavation design thought, the supporting form, the construction procedure design, the emergency plan compiling, the deep foundation pit excavation and the like is started, the influence of the complex surrounding environment, the complex geological condition, the complex relation between the foundation pits and the like on the plate zone extra-large deep foundation pit group construction is avoided, the collapse accident of the deep foundation pit group in the excavation process is prevented, the accidents such as sedimentation and inclination of surrounding buildings, roads and the like due to the excavation influence of the deep foundation pit group are avoided, and on the premise that the safety of the foundation pits and the surrounding environment is guaranteed, the construction efficiency is improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of construction of metallurgical workshops, in particular to a design method for a construction process flow of a super-large deep foundation pit group in a plate adding area of ​​a hot rolling mill. Background technique [0002] At present, in order to adapt to the development of the new environment, the domestic metallurgical iron and steel industry has entered a new round of relocation and transformation: [0003] In the 1780 hot rolling project of the third blast furnace system project of a large coastal steel mill in China, the two workshops of the slab warehouse and the heating furnace are arranged east-west, the slab warehouse workshop is in the west, and the heating furnace workshop is in the east. Construction in the factory", the construction situation of the deep foundation pit group in the Banjia area is very complicated, and the excavation is difficult, which is specifically reflected in: [00...

AI Technical Summary

Problems solved by technology

[0010] The purpose of the present invention is to solve the problem of the excavation sequence and method of the super large deep foundation pit group under complicated circumstances, and improve the construction efficiency and shorten the construction period under the premise of ensuring the safety of the foundation pit itself and the surrounding environment
