Embodiment 1

[0025] Embodiment 1: In this embodiment, the inclinometer tube is used to monitor the settlement of the ground surface under the existing buildings (structures) during tunnel shielding. Taking the West Xianxia Road Tunnel Project of Shanghai Hongqiao Comprehensive Transportation Hub as an example, the area under section 1 of the taxiway is planned to be selected as the micro-disturbance test area for non-excavation technology buried measuring points.

[0026] According to the existing research results, the fourth layer of soft soil in Shanghai area has certain differences in different regions, including water content, void ratio, strength, compressive modulus, sensitivity, etc. Therefore, even if the shield passes through the silty clay in the fourth layer, the degree of disturbance to the soft soil is different in different regions, and the amount of foundation deformation caused is also different. In order to make the construction parameters and grouting parameters of shield...

Embodiment 2

[0065] Embodiment 2: In this embodiment, the inclinometer tube is used to monitor the settlement of the ground surface under the road when the road is loaded. In order to make the expressway road smooth and run smoothly, it is necessary to carry out settlement monitoring of road load. In the design stage of the expressway, it is generally planned to embed the inclinometer tube in a certain section of the road, that is, to bury the inclinometer tube first, and then lay the road foundation above the inclinometer tube and repair the road. However, in the high-speed running process, sometimes it is necessary to monitor the settlement of the road load on the road section that has been built. At this time, the method of the present invention can be used to design an inclinometer pipe buried at the bottom of the road foundation without damaging the road. The setting track, usually a straight line of pilot holes crossing the foundation laterally. The drilling and reaming of the pilot...

Abstract

The invention relates to a method for monitoring the settlement by using an inclinometer tube. The inclinometer tube is embedded under the earth surface with an existing building (structure) by passing through the earth surface under the building and adopting a trenchless technology, and a monitoring point is arranged for monitoring the settlement. During the monitoring process, dynamic observation is conducted at the monitoring point according to the monitoring scheme so as to obtain the settlement information after the inclinometer tube is embedded and a media system around the inclinometer tube reaches a stable state. The method effectively monitors the settlement of deep soil body under the building (structure) in construction along the vertical direction, and lays a solid foundation for design, scheduling and avoidance measures of construction.

Description

technical field [0001] The invention relates to monitoring during underground construction, in particular to a method suitable for embedding inclinometer pipes under the surface of existing buildings (structures) to effectively monitor settlement changes. Background technique [0002] When the underground construction passes through the structure, it will inevitably disturb the soil. The multi-storey residential or public buildings with natural foundations have poor structural integrity. risk event. Therefore, it is very important to monitor the corresponding underground soil changes when studying the micro-disturbance technology of shield tunneling through buildings (structures), which is a hot issue in the development of underground space and rail transit construction. [0003] For various methods commonly used in settlement monitoring, such as single pile settlement analysis, pile group settlement analysis, etc., this method is likely to lead to large errors. Embedded i...
