Tunneling construction method for small section steep slope hydraulic tunnel

Abstract

The invention discloses a tunneling construction method for a small section steep slope hydraulic tunnel. The construction method comprises the steps that a current construction mode is obtained; a current monitoring condition is obtained, and an abnormal amount of buildings around the tunnel based on the monitoring condition is obtained; the abnormal amount is processed to obtain a processed abnormal amount based on the construction mode; the construction mode is adjusted based on the processed abnormal amount to obtain an adjusted construction mode; and the tunnel is continuously constructedin the adjusted construction mode. By dispersing the work amount controlled in the construction process into the subsequent construction steps according to the current construction mode and the abnormal variable quantity of the surrounding environment, the work amount controlled in the construction process is greatly reduced, the construction difficulty is greatly reduced, and the influence of construction process control on the existing construction environment is greatly reduced, thus the safety of the construction process control is improved, and at the same time, the advancement of existing construction projects is not affected and the construction efficiency is improved in the process of the construction process control.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a excavation construction method of a hydraulic tunnel with a small section and steep slope. Background technique [0002] With the continuous development of engineering technology and the continuous improvement of the ability to transform nature, people's ability to underground construction is also constantly improving. Further, with the continuous development of urbanization, the demand for underground construction in cities is also increasing. Big, more and more construction projects. [0003] During the tunnel excavation construction, along with the change and adjustment of the stratum stress state, the stratum and surface displacement and deformation are correspondingly caused. The outward transmission of stratum deformation is a gradual development process. Through the transmission to the top, bottom and side of the tunnel, it will affect the surfac...

Problems solved by technology

[0006] In order to overcome the technical problems in the prior art of controlling the construction process of tunnel construction, such as huge engineering quantity, high construction difficulty, low construction safety, and low construction efficiency, the embodiment of the present invention provides a small-section steep-slope hydraulic tunnel excavation construction method, according to the current construction mode and the amount of abnormal changes in the surrounding environment, the engineering quantity of the construction process control is distributed to the subsequent construction steps, thereby greatly reducing the engineering quantity of the construction process control, greatly reducing the construction difficulty, and greatly reducing In order to avoid the impact of construction process control on the existing construction environment, the safety of construction process control is improved. At the same time, the progress of existing construction projects is not affected during the construction process control process, so construction efficiency is also improved.
