Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a simple testing tool for the pile hole of cast-in-place piles. Background Technology

[0002] Cast-in-place piles are a type of pile foundation widely used in building foundation engineering. The construction method of cast-in-place piles is to first drill a hole in the foundation, then put a steel cage into the hole, and finally pour concrete to form the pile body.

[0003] After the pile hole construction is completed, the quality of the pile hole needs to be inspected. The inspection items include hole depth, hole diameter, and verticality. In the traditional pile hole inspection process, three tools are required to test each indicator. The inspection process is inconvenient and affects the inspection efficiency, and needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a simple testing tool for the pile hole of cast-in-place piles, which has the effect of improving testing efficiency and convenience.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a simple inspection tool for pile holes of cast-in-place piles, comprising:

[0006] The detection rod is arranged in a vertical cylindrical shape and has scale lines on its surface;

[0007] A base plate is horizontally positioned at the bottom of the detection rod;

[0008] A collar, which slides vertically and rotates to the detection rod;

[0013] In a preferred embodiment, the present invention can be further configured such that a screw is vertically disposed at the center of the base plate, and the screw is threadedly connected to the lower end of the detection rod.

[0014] In a preferred embodiment, the present invention can be further configured such that: the detection rod includes multiple rod sections, the upper end of the rod section is provided with a locking rod, and the upper end of the rod section is provided with a locking hole for the locking rod to be threaded into.

[0016] In a preferred embodiment, the present invention can be further configured such that an illumination lamp is obliquely disposed on the bracket and faces the scale.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. By setting a detection rod that can be inserted into the pile hole and setting scale lines on the detection rod, the hole depth can be measured. At the same time, a scale with sliding and rotating connection is set on the detection rod, which can control the rotation of the scale to measure the hole diameter.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] like Figure 1 , Figure 2 As shown, a simple inspection tool for the pile hole of a cast-in-place pile includes an inspection rod 1, a base plate 2, a collar 3, a ruler 4, and a level 5.

[0028] like Figure 1 , Figure 2 As shown, the detection rod 1 is arranged in a vertical cylindrical shape, and the surface is provided with scale lines 11. The detection rod 1 includes multiple rod sections 12, and the upper end of the rod section 12 is provided with a locking rod 13. The upper end of the rod section 12 is provided with a locking hole 14 for the locking rod 13 to be screwed in, so as to realize the assembly of the segmented detection rod 1.

[0029] like Figure 1 , Figure 2 As shown, the base plate 2 is horizontally positioned at the bottom of the detection rod 1, and a screw 21 is vertically positioned at the center of the base plate 2. The screw 21 is threadedly connected to the lower end of the detection rod 1 to enable quick assembly and disassembly of the base plate 2, thus meeting the installation requirements of base plates 2 with different diameters.

[0030] like Figure 1 , Figure 2 As shown, the collar 3 is vertically sliding and rotatably connected to the detection rod 1, the scale 4 is horizontally set on the outer walls of both sides of the collar 3, and the level 5 is set on the upper surface of the scale 4.

[0031] When it is necessary to inspect the pile hole, the multi-section rod 12 is tightened and fixed according to the different hole depths to complete the assembly of the inspection rod 1. Then, according to the size of the hole diameter, a base plate 2 of appropriate size is selected, and the base plate 2 is tightened and fixed to the lower end of the inspection rod 1 by screws 21. Finally, the collar 3 is placed on the outer wall of the inspection rod 1 to complete the assembly of the entire inspection tool.

[0032] Then, the testing rod 1 is vertically inserted into the pile hole, so that the base plate 2 contacts the bottom wall and bottom surface of the pile hole. Then, the testing rod 1 is deflected, and the level 5 on the scale 4 is observed to make the testing rod 1 completely perpendicular to the ground. Then, the collar 3 is controlled to slide downwards, so that the scale 4 is pressed firmly on the ground. Then, the position of the collar 3 on the testing rod 1 is observed, and the depth of the pile hole is determined according to the value of the scale line 11.

[0033] Then, keep the detection rod 1 still, control the collar 3 to rotate one revolution, and then observe the position of the pile hole wall on the scale 4. Select the longest distance between the two sections of the scale 4 as the diameter of the pile hole to obtain the diameter of the pile hole.

[0034] During the rotation of the collar 3, observe the position of the hole walls on both sides on the scale 4. If the position of the hole walls on the scale 4 on both sides does not change, it means that the detection rod 1 is coaxial with the pile hole, that is, the verticality meets the requirements. Otherwise, it means that the verticality does not meet the requirements.

[0035] Therefore, by setting a detection rod 1 that can be inserted into the pile hole and setting a scale line 11 on the detection rod 1, the hole depth can be measured. At the same time, a scale 4 with a sliding and rotating connection is set on the detection rod 1, which can be controlled to rotate and measure the hole diameter. Meanwhile, when the scale 4 rotates, the distance between the hole wall and the detection rod 1 is measured to measure the perpendicularity. All indicators can be measured quickly in one go, improving detection efficiency and convenience.

[0036] Example 2:

[0037] like Figure 3 As shown, a simple testing tool for the pile hole of a cast-in-place pile has a sliding ring 6 horizontally slidably connected to a scale 4, and a pointer 61 that abuts against the inner wall of the pile hole is provided at the lower end of the sliding ring 6. A screw 62 for pressing the scale 4 is vertically threaded onto the sliding ring 6.

[0038] When measuring the borehole diameter, if the length direction of a pair of scales 4 is collinear with the diameter of the pile hole, the control sliding ring 6 drives the pointer 61 to slide, so that the pointer 61 touches the inner wall of the pile hole. Then, the control screw 62 presses the upper end face of the scale 4 to fix the sliding ring 6. Subsequently, the borehole diameter can be recorded and accurately measured according to the position of the sliding ring 6.

[0039] Example 3:

[0040] like Figure 4 As shown, a simple inspection tool for the pile hole of a cast-in-place pile is provided. A bracket 7 is inclinedly provided on the collar 3. The upper ends of the brackets 7 are close to each other, and a handle 71 is vertically provided on the upper end and sleeved on the outer wall of the inspection rod 1. An illumination lamp 72 is inclinedly provided on the bracket 7 and faces the scale 4.

[0041] By setting the handle 71 to control the sliding of the collar 3, the sliding process of the collar 3 is made more convenient. At the same time, the illumination lamp 72 on the bracket 7 directly illuminates the scale 4, making it easier to read the scale value on the scale 4 in a dim environment, thus making the measurement process more convenient.

[0042] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
