Embodiment Construction

[0046] Below in conjunction with accompanying drawing and embodiment describe in detail:

[0047] 1. Device

[0048] 1. Overall

[0049] Such as figure 1 , the device includes working objects: test hole 7 and drill hole 8;

[0050] It is equipped with a basin-shaped guide groove 1, a probe 2, a lifting rope 3, a lock 4, a lifting ring 5 and a drill pipe 6;

[0051] Its location and connection relationship are:

[0052] Along the central axis of the test hole 7 and the borehole 8 that both overlap, from top to bottom, the drill pipe 6 and the probe 2 are connected by the thread 2.1 to form a test structure;

[0053] The upper part of the drill pipe 6 is provided with a lock 4 and a lifting ring 5 (the position of the lifting ring 5 is adjusted and fixed through the locking buckle 4). The buckles 1.2 are connected accordingly to form a guiding structure, and the end of the probe 2 passes through the guiding hole 1.1 of the basin-shaped guiding groove 1 and faces the testing...

Abstract

The present invention discloses an aiding device for arranging a probe in a variable cross-section borehole and belongs to the engineering survey in-situ testing technique field. The device is structured as the following manners: a drill pipe (6) and a probe (2) are connected with each other through a screw thread (2.1) from top to bottom along the central axes of a test hole (7) and a borehole (8) so as to form a test structure, the central axes of the test hole (7) and the borehole (8) being overlapped; the upper part of the drill pipe (6) is provided with a lock catch (4) and a hanging ring (5); the hanging ring (5), hanging ropes (3) and a basin-shaped guide groove (1) are connected with one another sequentially from top to bottom through hanging buckles (5.1) and pulling buckles (1.2) so as to form a guide structure; and one end of the probe (2) passes through a guide hole (1.1) of the basin-shaped guide groove (1) so as to be aligned with the test hole (7). With the aiding device adopted, the accurate arrangement of the probe in the variable cross-section borehole can be aided, and the probe can be arranged at an expected test depth; and disturbance on the borehole and the test hole can be avoided, and the integrity of the test hole can be ensured; and requirements of the arrangement of probes in boreholes and test holes of various kinds of diameters can be satisfied.

Description

technical field [0001] The invention relates to an in-situ test technology in engineering investigation, in particular to an auxiliary device for placing a probe in a variable-section borehole. Background technique [0002] In engineering investigation, it is necessary to use drilling technology to explore the formation. The formation drilling is obtained by drilling with a drilling rig, and in-situ testing and geophysical logging are carried out in the drilling to obtain formation information within the depth of the drilling and provide reference for engineering construction and resource development. At present, the geological drilling technology at home and abroad is becoming more mature, and the drilling equipment is relatively complete, which can carry out in-hole testing work under various geological conditions. [0003] When carrying out in-situ testing in a borehole with a single diameter, the probe can be lowered from the hole opening to the specified depth in the h...
