Embodiment 1

[0034] Example 1: Figure 1-18 As shown, a wave velocity testing and sampling equipment in a hole for geotechnical exploration is characterized in that it includes a drilling detection device (1), an impact sampling device (2), a protection device (3) and a dust removal device (4). The drilling detection device (1) is connected with the impact sampling device (2), the drilling detection device (1) is connected with the protection device (3), and the protection device (3) is connected with the dust removal device (4).

[0035] The drilling detection device (1) includes a percussion housing (101), a transmission housing (102), a probe barrel (103), a drill slide rail (104), a motor (105), a motor shaft (106), and a motor bracket ( 107), bevel gear (108), bevel tooth disc (109), vortex slide rail (110), vortex sliding claw (111), drill bit (112), worm gear (113), worm gear shaft (114), worm gear shaft support ( 115), pulley (116), belt (117), conveying disc shaft (118), disc sha...

Embodiment 2

[0042]The in-hole wave velocity testing and sampling equipment for geotechnical exploration in this embodiment is the same as that in Embodiment 1. The probe 125 transmits the detected parameters to the detection instrument 301 through the probe connection line 131 for analysis. The use environment of the detection instrument 301 is very harsh, and protection must be provided to prevent bumps. Position piece 404 limit, under the effect of pop-up spring 401, sliding post 402, instrument case upper cover 403 ejects along case hole 303, can operate detection instrument 301 at this moment, pushes push-pull plate 306 in instrument case 302, and push-pull plate 306 The inclined surface of the contact with the lifting block 307 drives the lifting block 307 to move downward, the lifting block 307 drives the clamping plate 308 to move, the clamping plate 308 drives the grooved pull rod 310 to move downward through the clamping plate lug 309, and the grooved pull rod 310 Pull the pull c...

Abstract

The invention discloses in-hole wave velocity test sampling equipment for rock-soil exploration and a sampling method, and relates to the field of rock-soil exploration, the sampling equipment comprises a drilling detection device, an impact sampling device, a protection device and a dust removal device, the drilling detection device is connected with the impact sampling device, the drilling detection device is connected with the protection device, and the protection device is connected with the dust removal device. A detector holds the grab handle with a hand to keep the impact sampling device vertical, the impact sampling device generates impact to enable the drill bit to continuously punch downwards and make detection preparation, after a hole is punched to a proper depth, the drilling detection device stretches out the probe, the probe pierces into rock soil, detection is started, and the probe transmits detection data into the detection instrument through the connecting line. The impact sampling device can sample different layers in rock soil, the protection device can protect a detection instrument to prevent collision, and the dust removal device can remove dust around the detection instrument to keep the instrument clean. The process is simple, and operation is convenient and fast.

Description

technical field [0001] The invention relates to the field of geotechnical exploration, in particular to an in-hole wave velocity testing sampling device and sampling method for geotechnical exploration. Background technique [0002] In the field of geotechnical exploration, the wave velocity test can divide the site type, calculate the basic period of the site, provide the dynamic parameters of the foundation soil required for seismic response analysis, judge the possibility of foundation soil liquefaction, and evaluate the effect of foundation treatment. Traditional equipment is inconvenient to operate and cannot be convenient and fast. The completion detection of the present invention solves the above-mentioned problems. Contents of the invention [0003] The object of the present invention is to provide an in-hole wave velocity testing and sampling device for geotechnical exploration, which can conveniently complete drilling and testing, and can provide protection for t...
