Monitoring method for original well, receiving well and pipe jacking construction

Abstract

The invention discloses a monitoring method for an original well, a receiving well and pipe jacking construction. The monitoring method comprises the steps that (1), construction is prepared on site; (2), monitoring points are selected, and monitoring instruments are arranged on monitoring sections of the monitoring points; (3), monitoring frequency is made, and information is collected; (4), collected information data are recorded, analyzed and treated, and a monitoring statement is obtained; (5), a monitoring warning index value is made; and (6), the reasonability and scientificity of the construction process are evaluated according to the monitoring statement and the monitoring warning index value. On the basis of common monitoring items, the monitoring items are combined organically, and the tested data can be mutually checked. Continuous monitoring is conducted in construction engineering to guarantee the continuity of the data; monitoring point arranging is reduced by utilizing the system effect, so that the cost is saved; and by combining construction practice, the testing method and the types of monitoring elements are determined, and the arranging positions of the monitoring points are adjusted, so that the influence on the construction quality is reduced.

Description

technical field [0001] The invention relates to a civil engineering monitoring method, in particular to a monitoring method for starting and receiving wells and pipe jacking construction. Background technique [0002] With the development of my country's national economy, the demand for infrastructure, especially for transportation facilities, is increasing, and land transportation such as railways and highways is the first to bear the brunt; at the same time, high-level traffic arteries have also achieved unprecedented development, such as: High-speed, heavy-duty railways and expressways are the main directions for the development of land transportation such as railways and highways respectively, and the construction of urban subways and highway tunnels is an important means to ease urban traffic. The improvement and capacity expansion of transportation facilities, vehicle speed increase and the development of expressway network inevitably lead to the emergence of a large nu...

Problems solved by technology

Due to the lack of understanding and attention to the complexity of construction, engineering accidents caused by such problems also occur from time to time. For example, when a second line was added to a single-track railway, the new tunnel was constructed adjacent to the existing tunnel. The deteriorated existing tunnel structure deteriorated further; a highway tunnel passed through the goaf, due to insufficient investigation in advance, no countermeasures were taken during design, resulting in cracking of the lining after construction, etc.
