Inclination measurement hole construction method

Abstract

The invention provides an inclination measurement hole construction method. The method includes the steps of inclination measurement connector processing, mortar manufacturing, mud pipe processing, pouring and pier foundation pouring. An opening in the bottom of the first lowered inclination measurement pipe is closed before inclination measurement pipes are lowered, the joints of the inclination measurement pipes and casting pipes are sealed in the lowering process, rivet anchoring positions are closed through plasticine, and seams possibly existing between the inclination measurement pipes and inclination measurement drilled holes are completely closed through external wound adhesive tape; mortar with which the gaps between the inclination measurement pipes and the inclination measurement drilled holes are filled is composed of gravel and cement paste, and gravel is evenly added when cement paste is poured from bottom to top through a high-pressure pump; cement paste pipes fixed to the inclination measurement pipes each comprise a smooth-surface mud pipe located on the top and a mud pipe located on the lower portion and provided with holes, and in other words, grouting holes are evenly formed in the pipe walls of the multiple mud pipes located on the lower portion; the pouring method from bottom to top is ensured, and meanwhile guniting pressure is effectively reduced and the aim of safe construction is achieved.

Description

technical field [0001] The invention relates to a method for constructing an inclinometer hole, which belongs to the technical field of geological disaster monitoring. Background technique [0002] China is a country with frequent geological disasters, and landslide disasters in mountainous areas are particularly prominent. However, due to the high cost of landslide control, only a small part of the landslides that can be effectively controlled, and a large part of the landslides need to be monitored for landslides, such as groundwater Monitoring, surface displacement monitoring, GPS monitoring, deep inclinometer monitoring, etc. Among them, the deep displacement monitoring is mainly suitable for creeping landslides. The deformation of this type of landslide is slow, and the displacement often fluctuates at the centimeter or even millimeter level. Therefore, the monitoring accuracy of the instrument is high, and the construction technology of the inclinometer hole is very st...

AI Technical Summary

Problems solved by technology

[0003] like Figure 4 As shown, the traditional inclinometer hole construction uses clay 15 backfill compaction, because the clay is uneven and massive, and the gap between the outer wall of the inclinometer pipe 2 and the wall of the inclinometer borehole 1 is small, etc., often resulting in insufficient backfill compaction , resulting in partial hollow outside the inclinometer tube, slight shaking of the inclinometer tube, large data errors, etc.
