Description
Technical Field
The utility model relates to a reaming pile measuring technology, in particular to a reaming position measuring device for a reaming pile.
Background
With the continuous promotion of urbanization construction, the type of urban buildings inevitably develops to high-rise buildings and super high-rise buildings, and in order to meet the actual engineering requirements, the drilling and bottom-expanding cast-in-place pile is improved and innovated on the basis of the drilling cast-in-place pile. The diameter of the pile end is enlarged by replacing a special drill bit at the pile end after the pile reaches a required bearing layer by drilling, so that the ultimate bearing capacity of the pile is greatly increased compared with that of a cast-in-place pile without an enlarged head, the drilled and bottom-expanded cast-in-place pile can be used for finishing holes in strongly weathered rocks, the defects of other pile types can be overcome, and the economic benefit is remarkable.
At present, a bored and club-footed cast-in-place pile is generally applied in engineering, but the conditions of club-footed are different due to different geological conditions and human factors. Because the pile foundation degree of depth is long, the reaming condition is only judged according to the constructor to lead to pile foundation reaming condition quality to be difficult to judge. Therefore, there is a need for a device for measuring the width and the reaming depth of the reamed portion of a reamed pile, thereby ensuring the construction quality of a bored and club-footed bored pile.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a device for measuring the reaming part of a reaming pile, which can effectively realize the measurement of the width and the reaming depth of the reaming part of the reaming pile.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
the utility model provides a reaming pile reaming position measuring device, measuring device includes sleeve part and measurement portion, the sleeve part includes well core rod and sleeve, well core rod links to each other with the sleeve upper end, and the sleeve can be adorned on well core rod with reciprocating, measurement portion includes measuring stick, compression spring and dynamometer, the upper end of measuring stick links to each other with well core rod, set up compression spring between the middle section of measuring stick and the well core rod, the dynamometer sets up on well core rod, the measuring point of dynamometer is compression spring and well core rod's contact point.
The technical conception of the utility model is as follows: the center rod is connected with the upper portion of the measuring rod and can move relatively, the middle portion of the measuring rod is connected with the center rod through the compression spring, the dynamometer is placed at the connecting position of the springs, the length change of the springs can be obtained through the degree change of the dynamometer, and specific construction parameters such as the width and the depth of the bottom expanding portion of the drilling bottom expanding filling pile can be calculated according to the depth of the center rod and the geometric relation between the center rod and the depth of the center rod so as to ensure the engineering quality of the drilling bottom expanding filling pile.
The beneficial effects of the utility model are mainly shown in: the width and the reaming depth of the reaming part of the reaming pile are effectively measured.
Drawings
Fig. 1 is a schematic view of a reaming site measuring device for a reamed pile.
Fig. 2 is a schematic view of a measurement state.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
Referring to fig. 1 and 2, a reaming pile reaming position measuring device, including well core rod 1, sleeve 2, measuring stick 3, compression spring 4 and dynamometer 5, well core rod 1 links to each other with 2 upper ends of sleeve, but relative movement, and 3 upper ends of measuring stick link to each other with well core rod 1, and wherein compression spring sets up between 3 middle sections of measuring stick and well core rod, and dynamometer 5 sets up in well core rod, is in compression spring's contact point for measure compression spring length.
The sleeve diameter is 500mm, slightly is less than general drilling bored concrete pile, and well core rod setting is 200mm at sleeve internal diameter, and the diameter is 1000mm when both sides measuring stick struts completely, satisfies most drilling club-footed bored concrete pile's the condition of expanding the end.
In this embodiment, measuring the reaming width and depth of the reaming pile is performed according to the following steps:
A. pressing the central rod out of the sleeve, wherein the spring expands the measuring rod outwards due to the compression state of the spring until the measuring rod touches the inner wall of the pile foundation, and the reading of the dynamometer changes at the moment;
B. when the measuring part is a reaming part, the indicating number of the dynamometer is continuously changed to be unchanged, when the dynamometer begins to change, the depth of the central rod is H1, the central rod is pushed to the bottom, the indicating number is H2, and the reaming depth of the reaming pile is H2-H1;
C. for measuring the reaming width of reaming stake, when the central rod pushes away to the bottom, the dynamometer registration is F, can calculate the spring length X who reachs this moment through hooke's law, and the spring coupling is on central rod, and spring coupling department and measuring stick and central rod junction distance are H, and measuring stick and central rod junction and central rod bottom distance are H, according to similar theorem, reaming stake width is 2H X ÷ H.
The embodiments described in this specification are merely examples of implementations of the inventive concepts, which are for illustrative purposes only. The scope of the present patent shall not be considered limited to the specific forms set forth in the examples, but rather the scope of the present patent shall be deemed to be equivalent to the technical solutions that can be conceived by one of ordinary skill in the art based on the present inventive concept.
