Description

Technical Field

[0001] The utility model relates to the technical field of bridge cushion stone construction, in particular to a detection device for reserved and embedded holes of support cushion stones. Background Art

[0002] During the construction of spherical bearing pad stones, anchor holes are often constructed in a reserved and pre-buried manner. During the construction process, the anchor holes may deviate due to various reasons. In order to save materials and facilitate construction operations, the reserved diameter of the anchor holes will be reduced as much as possible. The deviation caused by the construction may cause the bearing anchor rods to be unable to be smoothly inserted; therefore, after the pad stone construction is completed, personnel are often required to review and correct it.

[0003] The current review method is often that the surveying personnel lay out the center line of the support in advance, and the construction personnel measure it with a tape measure, and determine whether the construction requirements can be met based on construction experience, but it is impossible to accurately determine whether the hole position and depth meet the requirements.

[0004] In summary, it is very necessary to propose a bearing cushion stone reserved and embedded hole detection device that can accurately determine the hole position and hole depth. Utility Model Content

[0005] The utility model aims to provide a detection device for reserved and embedded holes of support cushion stones, which solves the problem that the current review method cannot accurately determine whether the hole position and hole depth meet the requirements.

[0006] To achieve the above-mentioned purpose, the utility model adopts a support cushion stone reserved embedded hole detection device, including a cross ruler, a movable ruler sleeve, two positioning rulers and a hole inspection ruler, the hole inspection rulers respectively penetrate the two positioning rulers, each of the positioning rulers is respectively sleeved with the movable ruler sleeve, and the cross ruler is arranged below the two positioning rulers; the cross ruler includes a mounting column and four rotating rulers, each of the rotating rulers is respectively rotatably connected to the mounting column, and are all located below the positioning ruler.

[0007] Wherein, the side surface of the rotating ruler has a first reading; wherein the first reading increases sequentially from the cross center line to the ruler end.

[0008] Wherein, the movable ruler sleeve has a ruler sleeve opening and a degree hole, and the positioning ruler passes through the ruler sleeve opening.

[0009] Wherein, the positioning ruler has an opening.

[0010] Wherein, the positioning ruler has a second reading.

[0011] Wherein, the hole testing ruler comprises a circular ring end and a vertical ruler, the vertical ruler is threadedly connected to the circular ring end, and the vertical ruler passes through the opening.

[0012] Wherein, the vertical ruler has scales.

[0013] The utility model is a detection device for reserved and embedded holes of a support shim. The measurement personnel first release the center line of the support of the shim, align the cross ruler with the center line of the support, adjust the movable ruler sleeve to the center position of the support, insert the positioning ruler into the movable ruler, and adjust the positioning ruler so that the extended length of the positioning ruler meets the design requirements. After the positioning rulers in two directions determine the elongated size, put the hole inspection ruler into the anchor hole and gently lower the hole position. If no obstacles are encountered, it is clearly stated that the anchor hole meets the requirements. If obstacles are encountered, record them, determine the direction of the obstacles, and mark them for easy handling by personnel. Through the above method, the effect of being able to accurately judge the hole position and hole depth is obtained. BRIEF DESCRIPTION OF THE DRAWINGS
