Abstract
Description
[Technical field]
[0001] The invention relates to an angle-adjustable drilling machine auxiliary device used for coring detection of building retaining walls. [Background technology]
[0002] For the detection of retaining wall dimensions, the specification recommends the use of pit exploration, direct measurement, non-destructive testing and drilling methods. However, in actual projects, the pit exploration method involves a large amount of excavation and has an impact on the safety of the retaining wall, so it is rarely used. The direct measurement method can only measure the apparent dimensions. Since most retaining walls have variable cross-sections, the shape of the wall back under concealed projects cannot be obtained. The non-destructive testing method is affected by the differences in the characteristics of the retaining wall itself and the surrounding soil, and needs to be combined with other means to ensure detection accuracy. The drilling method can directly obtain the cross-sectional dimensions, which is simple, intuitive and highly accurate. It is currently the main means of retaining wall detection.
[0003] At present, the equipment for concrete coring detection on the market is mostly used in the building construction and road industries. The coring direction is vertical. When horizontal coring is required, the survey drill rig (such as XY-100, etc.) is often improved. Although coring can be carried out at the bottom of the retaining wall, coring in the middle of the wall and above is extremely difficult due to the heavy equipment. If road concrete coring equipment (such as diamond drilling machine, etc.) is used, the drill rig must be fixed to the wall with a bracket. The coring efficiency is high, but the coring angle cannot be adjusted. That is, for building retaining walls with a certain slope on the wall, the coring angle is difficult to accurately control, and the accuracy of retaining wall size detection cannot be guaranteed.
[0004] Since the retaining wall site in urban communities is relatively narrow, conventional survey drills have strong core drilling capabilities, but they have disadvantages such as high cost, inconvenient mobile assembly, and large operating space during construction, making coring difficult to achieve. Small handheld drills are light and convenient, but the coring depth is mostly 600-700mm, which cannot drill through the retaining wall. In addition, the angle of coring is maintained by visual inspection and hand-held, and there is an error in the coring angle. In particular, the retaining wall surface is often not vertical and there is a certain angle, which makes it difficult to accurately control the drilling angle when drilling horizontally. [Summary of the invention]
