Description

Technical Field

[0001] The present invention relates to the technical field of methods for photographing inside a borehole, and in particular to a method for photographing inside a drilling turbid water purification hole based on polyacrylamide flocculation technology. Background Art

[0002] In engineering practice, the water within channels created by concrete core holes, PHC pipelines, and geological survey boreholes is composed of a dispersed system of metal powder, hydrated colloids, and mud, sand, and gravel powder, resulting in a relatively stable turbid state. Using channel cameras to record images within the channels presents difficulties due to the turbidity of the water. To obtain high-quality channel images through the water medium, conventional solutions include allowing the water to settle, which requires a long settling time, or washing the channels with fresh water, which results in repeated disturbances and turbidity, a time-consuming and labor-intensive approach with minimal effectiveness.

[0003] In the prior art, for example, Chinese utility model patent CN202223393924.1 discloses a borehole camera lens suitable for muddy water environments, in which a transparent glass ball cover is provided between the lens and the muddy water body, and the space between the lens and the ball cover is filled with clean water in order to capture clear images; another example is Chinese utility model patent CN202320588868.2 discloses a muddy water imaging device, which, by providing a scraping component between the transparent glass cover and the annular water mist, is used to solve the problem of contamination and obstruction of the camera lens due to internal and external temperature differences and colloidal impurities, thereby continuing to capture images. However, the above inventions only solve the technical problem of imaging difficulties caused by the obstruction of the camera lens by the attachment of scattered floating objects in the muddy water body. In actual use, the camera still cannot completely penetrate the muddy water body to record clear channel video.

[0004] At present, conventional borehole television equipment is suitable for recording dry holes, or using multiple water replacement and static sedimentation to wait for the water to become clear before recording. For wet holes, deep holes, and holes that cannot be replaced with clean water, or holes that remain turbid after replacement, such as exploration holes that pass through soil layers, PHC pipe piles, concrete core holes where piles are damaged and penetrate the soil layer, etc., the use of conventional hole recording methods has obvious technical bottlenecks and application shortcomings. Therefore, there is an urgent need for a simple, efficient, and adaptable hole recording technology method. Summary of the Invention

[0005] 1. Technical Problems Solved

[0006] The technical problems to be solved by the present invention are the various problems mentioned in the above background technology, and a method for purifying turbid water bodies in a borehole by taking pictures based on polyacrylamide flocculation technology is provided.

[0007] 2. Technical Solution

[0008] To solve the above technical problems, the present invention provides a technical solution: a method for purifying turbid water in a borehole by taking in-hole images based on polyacrylamide flocculation technology, comprising the following steps:

[0009] S1. Drill a hole on the surface of the object, ensuring that the hole size is larger than the size of the channel camera;

[0010] S2. After the drilling is completed, a certain amount of flocculant is added into the hole according to the hole depth, and the water is allowed to stand to allow the turbid water in the hole to settle and the water to clarify quickly;

[0011] S3. Use a channel camera to shoot inside the hole and collect channel image information.

[0012] As an improvement, the flocculant in step S2 is a polyacrylamide flocculant.

[0013] As an improvement, the flocculant in step S2 is an inorganic flocculant such as aluminum chloride, ferric sulfate and polyaluminum chloride.

[0014] As an improvement, the flocculant powder or mother liquor used in step S2 is colorless and transparent.

[0015] As an improvement, the channel camera selected in step S3 is an automatic circular scanning or intelligent pedometer device channel camera.

[0016] 3. Beneficial Effects

[0017] The advantages of the present invention over existing technologies are as follows: It uses polyacrylamide as a primary flocculant to flocculate and precipitate the water within the borehole. This allows the turbid water colloidal system to contact, collide, and destabilize under the action of the added flocculant, resulting in agglomeration into large-particle aggregates. Further flocs are agglomerated through chemical adsorption, electrical neutralization, and a net-capture sweeping effect. These flocs then rapidly settle under gravity, rapidly clarifying the water and achieving rapid flocculation and water purification. Subsequently, a borehole camera is used to capture information and images within the purified water. The present method can accelerate water purification within the borehole and achieve high-definition borehole imaging. BRIEF DESCRIPTION OF THE DRAWINGS
