Abstract
The invention discloses a coursed deformation measurement method capable of eliminating sedimentation pipe influence. A device mainly consists of a deformation measurement magnetic ring capable of adjusting the diameter, a locating ring, and a sedimentation pipe. The coursed deformation measurement method is as follows: the deformation measurement magnetic ring capable of adjusting the diameter is fixed on the sedimentation pipe by a temporary cinch line, a temporary fixing pin, and the locating ring; after the sedimentation pipe is placed to a preset position in a drilled hole, the temporary fixing pin can be pulled out by the cinch line; a tension spring leads the diameter of the deformation measurement magnetic ring capable of adjusting the diameter to be enlarged and tightly stuck on the wall of the drilled hole; in the way, not only can the accurate locating of the initial position of the deformation measurement magnetic ring capable of adjusting the diameter in a soil horizon be guaranteed, but also the filled backfill materials can be smoothly fed into a gap between the sedimentation pipe and the wall of the drilled hole; therefore, the constrains and influences of the sedimentation pipe on the deformation measurement magnetic ring capable of adjusting the diameter are greatly reduced; the detailed position of the deformation measurement magnetic ring can be detected through an electromagnetic probe in the sedimentation pipe; and the measured coursed deformation value of a soil mass is more accurate.
Description
Technical field
The present invention relates to a kind of mensuration soil body delaminating deposition or protuberance distortion in the Soil Mechanics and Foundations foundation works, and can eliminate the electromagnetic type layering deformation measurement method of sedimentation pipe influence.
Background technology
At present; Carrying out the electromagnetic type layering deformation measurement device that soil body layering distortion adopted both at home and abroad generally all is closed circular annular layering deformation measurement magnet ring, locating ring by fixed diameter, and is fixed on spring leaf on the layering deformation measurement magnet ring, sedimentation pipe, supporting compositions such as sedimentometer.Being determined at of soil body layering distortion there is not too big variation on the method; And to the development of layering anamorphic attachment for cinemascope with improve the aspects such as structure and function of the material of the main size that changes the magnet that concentrates in the magnet ring, layering deformation measurement magnet ring, sedimentation pipe, supporting sedimentometer, the advanced at present and higher sedimentometer of automaticity can be realized data automatic collecting and storage.
When at present the soil body being carried out the layering deformation measurement; The method that adopts all is the outer wall indicator that up-down is out of shape as the soil body that the closed circular annular layering deformation measurement magnet ring of the fixed diameter that has spring leaf is enclosed within sedimentation pipe with the locating ring segmentation; The external diameter of locating ring is bigger than the internal diameter of layering deformation measurement magnet ring; And guarantee between layering deformation measurement magnet ring and the sedimentation pipe certain clearance to be arranged, so that layering deformation measurement magnet ring can freely be slided up and down when installing along the outer wall of sedimentation pipe.The method that layering deformation measurement magnet ring is installed is generally following: the sedimentation pipe bottom is installed earlier on sedimentation pipe; Overlap higher slice deformation measurement magnet ring again; After the deformation measurement magnet ring moved to the precalculated position; Descend both sides to fix two locating rings above that, the deformation measurement magnet ring can be moved between locating ring, adopt interim bundle such as paper string that the spring leaf on the layering deformation measurement magnet ring is tied up on sedimentation pipe then; Make layering deformation measurement magnet ring can get into boring smoothly, and before burying the location underground, make the layering deformation measurement magnet ring can not be along the free slippage downwards of sedimentation pipe.When the layering distortion of measuring the soil body; Look the situation such as soil property of soil layer, the boring of in soil layer, boring the big certain size of a diameter score layer deformation measurement magnet ring external diameter with drilling tool earlier, the sedimentation pipe that will just install layering deformation measurement magnet ring then in advance is piecemeal down in boring; After sedimentation pipe installs; Adopt immersion or other method that interim bundle such as paper string is unclamped, let spring leaf open and be fixed on the borehole wall, will hole with sand or other backfilling material again and sedimentation pipe between the space fill up.But adopt the layering deformation measurement device of this method and structure in use also to come with some shortcomings; At first be to avoid backfilling material to get in the gap between deformation measurement magnet ring and the sedimentation pipe; Make the friction force between deformation measurement magnet ring and the sedimentation pipe excessive; Or backfilling material and sedimentation pipe friction force are bigger, cause the deformation measurement magnet ring to receive the very big constraint of sedimentation pipe with the up-down of the soil body, and the external diameter of locating ring are bigger than the internal diameter of layering deformation measurement magnet ring; To receive the restriction of locating ring when the deformation measurement magnet ring moves up, so just cause the soil body layering deformation values distortion of being measured easily; In addition; Because being fixed on has bigger distance between two locating rings up and down on the sedimentation pipe; And interim bundle such as paper string can not guarantee that layering deformation measurement magnet ring is not shifted when sedimentation pipe is put into boring, thereby causes the accurate location of the initial position of layering deformation measurement magnet ring when installation in position relatively more difficult.Though some user avoids backfilling material to get in the gap between deformation measurement magnet ring and the sedimentation pipe; Taked to add methods such as telescopic corrugated tube, but still can't effectively eliminate the effect of contraction of sedimentation pipe the deformation measurement magnet ring such as cover between deformation measurement magnet ring and sedimentation pipe; Initial accurately orientation problem to layering deformation measurement magnet ring does not have good solution yet.
