Problems solved by technology

Monitoring the settlement and displacement of deep soil can understand the scope and influence of soil disturbance during shield tunneling, but it is difficult to install monitoring equipment in place, and construction safety is extremely important
Using a horizontal inclinometer for horizontal inclinometer monitoring, although it can ensure the non-excavation of the excavated soil surface, has the limitation that the accuracy is difficult to guarantee

Embodiment Construction

[0014] The features of the present invention and other related features will be further described in detail below in conjunction with the accompanying drawings through embodiments, so as to facilitate the understanding of those skilled in the art:

[0015] Figure 1-4 The middle marks 1-16 represent: Taxiway 1, North Line Tunnel Design Center Line 2, North Line Tunnel Structure Side Line 3, South Line Tunnel Design Center Line 4, South Line Tunnel Structure Side Line 5, Horizontal Directional Drilling 6, Drill Pipe 7. Drilling point 8, casing 9, drill pipe 10, drill bit 11, excavation point 12, PE casing 13, monitoring pipe 14, transfer case 15, back expander 16.

[0016] During the construction of the tunnel, it is necessary to monitor the settlement of the road above it when the shield is jacking. In this embodiment, it is necessary to monitor the subsidence of the ground below the airport taxiway 1 when the tunnel shield construction is advancing. Since the piles cannot b...

Abstract

The invention relates to the fields of monitoring and construction, in particular to a construction method for embedding an inclinometer tube suitable for monitoring the earth surface settlement. The construction method arranges the inclinometer tube in a sleeve according to the embedding track of the inclinometer tube, uses a sleeve type drag pipe when the inclinometer tube is drawn into a pore path, i.e., the sleeve and the inclinometer tube are drawn out of the pore path together by drawing the sleeve with the interior containing the inclinometer tube, instead of directly drawing the inclinometer tube, and then mud is filled in the gap between the sleeve and the inclinometer tube fully, the sleeve is stripped off and the inclinometer tube is put in the right position. The construction method can lead the inclinometer tube to be put in the right position accurately without twisting and does not affect the accuracy of monitoring.

Description

technical field [0001] The invention relates to the field of monitoring construction, in particular to a construction method for embedding an inclinometer pipe suitable for monitoring surface settlement. Background technique [0002] In engineering construction, especially in underground construction, various monitoring methods are often used to prevent and monitor problems such as surface settlement caused by construction, such as single pile settlement analysis, pile group settlement analysis, etc. This method is likely to lead to relatively large errors. Large, and must bypass existing buildings (structures). Usually, embedded inclinometer tubes are also used to measure and calculate settlement. For example, during highway construction, a straight-line inclinometer tube is usually buried at the bottom of the foundation to monitor settlement. However, when there are tall buildings on the surface or the length and span are too large to pass through, the positioning of pile...
