Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a rock and soil drilling support device. Background Art

[0002] Geotechnical drilling is an exploration method used to obtain the physical properties, engineering properties and groundwater conditions of underground geotechnical layers. Through drilling, important information such as the distribution, thickness properties and groundwater conditions of underground geotechnical layers can be obtained, providing the necessary basis for engineering design and construction; however, after drilling, the borehole usually needs to be supported to prevent it from collapsing, resulting in unnecessary repeated drilling during secondary surveys; the traditional method is to cut a PVC water pipe and insert it into the borehole for support, but this method has some disadvantages. First, the depth of the borehole cannot be known in advance, and a long PVC pipe needs to be carried for on-site interception, which is inconvenient to carry and troublesome to intercept; second, the wall of the PVC pipe is opaque, and the PVC pipe needs to be taken out for secondary survey before the survey can be carried out, and the borehole will still collapse after losing support, which affects the survey. It is based on the above reasons that we have proposed a geotechnical drilling support device. Utility Model Content

[0003] The purpose of the present utility model is to provide a rock and soil drilling support device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a rock drilling support device, comprising a support tube, the support tube being a cylindrical tube body, a docking thread being provided at the top of the inner cavity of the support tube, and a docking screw head being provided at the bottom of the support tube; an observation window being provided on the support tube, the observation windows being provided with two symmetrical front and rear portions, and a battery box being provided at the upper portion of one side of the support tube;

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0015] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0016] Embodiment:

[0017] Please refer to Figure 1-2 , the present utility model provides a technical solution for a rock and soil drilling support device: including a support pipe 1, the support pipe 1 is a cylindrical pipe body, a docking thread 2 is provided at the top of the inner cavity of the support pipe 1, and a docking screw head 3 is provided at the bottom of the support pipe 1;

[0018] Multiple groups of support pipes 1 are provided and are connected up and down. When connected, the docking screw head 3 is installed downward in the docking thread 2 of the lower support pipe 1;

[0019] Observation windows 4 are provided on the support pipe 1, there are two observation windows 4 that are symmetrically arranged front and back, and a battery box 5 is provided on the upper part of one side of the support pipe 1;

[0020] An illumination lamp bead 6 is provided in the side wall of the junction between the support pipe 1 and the observation window 4, and the illumination lamp bead 6 illuminates the position of the observation window 4;

[0021] A vibration switch 7 is embedded in the top of the junction between the support tube 1 and the observation window 4. A battery is provided in the battery box 5. The vibration switch 7 is electrically connected to the battery and the lighting lamp bead 6 respectively; a delayed closing circuit is also provided between the vibration switch 7 and the lighting lamp bead 6;

[0022] This solution provides a support device for preventing the collapse of a drill hole and making it easy to observe. Specifically, multiple groups of support pipes 1 are taken, and the number of support pipes is extended according to the depth of the drill hole to form a support pipe group. During installation, the two ends of the support pipe 1 are connected at the first position, and the docking screw head 3 is screwed into the docking thread 2 at the top of the lower support pipe 1. The installed support pipe group is inserted into the drill hole for support, which can prevent the drill hole from collapsing and facilitate secondary exploration in the later stage.

[0023] However, the traditional pipeline has no observation function, so the support pipe 1 is provided with an observation window 4, which is made of transparent material. The rock and soil layers can be viewed through the observation window 4. Usually, the depth of rock and soil drilling is between 2-5m, so it can be surveyed with the naked eye, which is very convenient.

[0024] An illuminating lamp 6 is provided at the junction of the support pipe 1 and the observation window 4, which is powered by the battery in the battery box 5. The illuminating lamp 6 illuminates the observation window 4 and the rock and soil layer, providing auxiliary fill light for easy viewing with the naked eye.

[0025] At the same time, a vibration switch 7 is provided on the support tube 1. The principle of the vibration switch 7 is to activate the switch by the vibration frequency, thereby opening the path between the lighting lamp bead 6 and the battery. When in use, knocking on the tube body of the uppermost support tube 1 will cause the vibration to trigger the multiple sets of vibration switches 7 below.

[0026] A delayed closing circuit is provided in the circuit. The delayed closing circuit keeps the circuit open within 10-20 seconds through the control of an internal timer. The lighting bead 6 continues to illuminate the position of the observation window 4. When the time is up, the circuit is closed and the connection between the lighting bead 6 and the battery is disconnected. The principle of the delayed closing circuit is prior art and will not be described in detail here.

[0027] Usually, a built-in battery on-off switch that can be pushed left and right is provided on the battery box 5. This part is prior art and will not be described in detail.

[0028] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic features of the present utility model, the present utility model can be implemented in other specific forms.
