Problems solved by technology

[0007] For the relatively narrow space in the shaft, it is also difficult to choose the construction location of the water level observation hole. At the same time, the tunneling speed will also be restricted due to the influence of the water level observation hole during the formal excavation of the frozen shaft.

Embodiment Construction

[0031] A water level observation tube capable of layered reporting of the circumstance of a frozen wall, comprising N horizon observation tubes, where N is a positive integer and greater than or equal to 2; the N horizon observation tubes are coaxially sleeved together, and The upper ends are protruding from the ground, and the lower ends are located at different observation levels.

[0032] In this embodiment, N is 4, that is, there are four observation horizons.

[0033] like figure 1 Shown: the horizon observation tube includes a φ76 seamless steel pipe 9 for reporting the intersection of the frozen wall at the first horizon, a φ108 seamless steel tube 10 for reporting the intersection of the frozen wall at the second horizon, and a The φ133 seamless steel pipe 11 for reporting the intersection of the frozen wall at the third horizon and the φ159 seamless steel tube 12 for reporting the intersection of the frozen wall at the fourth horizon, the first horizon, the second ho...

Abstract

The invention discloses a water level observation tube capable of reporting the intersection of frozen walls in layers, comprising N layer observation tubes, where N is a positive integer greater than or equal to 2; the N layer observation tubes are coaxially set on together, and the upper ends all protrude from the ground, and the lower ends are respectively located at different observation horizons; on each of the horizon observation pipes corresponding to the return water pipe wall of the horizon to be observed, there is a The return water holes that are turned on, and the return water holes of each horizon observation tube are not connected to each other. The water level observation tube of the present application allows only one water level observation hole to be constructed in each wellbore, which can report the water level of multiple layers, complete the reporting tasks of different layers, reduce the number of construction water level observation holes, reduce construction costs, save construction time, and speed up The speed of well completion reduces the possibility of water crossing in the water level observation hole, reduces the risk of difficult crossing of the frozen wall caused by the crossing of the water level hole, and ensures that the process of crossing the frozen wall is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of freezing construction. Specifically, it is a water level observation tube that can realize layered reporting of the circumstance of the frozen wall. Background technique [0002] Freezing well sinking is a construction method that uses artificial refrigeration technology to temporarily reinforce unstable strata and isolate groundwater. The freezing method is suitable for loose and unstable alluvial formations, fractured aquifers, soft mudstones, and rock formations with particularly large water content and water pressure. It can be used not only as a formal construction method for mine engineering with complex geological conditions, but also as a means of engineering rescue and accident handling. It is widely used in the construction of vertical shafts, inclined shafts, horse head gates, etc. Subway, bridge and culvert, large-volume underground chamber and deep foundation pit engineering. [0003] In t...
