[0002] Construction engineering refers to the general term for various buildings and engineering facilities that provide the material and technical basis for human life and production. In building construction inspection, the quality inspection of bored piles is an important part. Whether the diameter of the pile hole is uniform up and down and meets the design requirements, and whether the pile hole is a standard cylinder according to the design will directly affect the mechanical properties of the pile foundation after the subsequent pile foundation concrete pouring. It is necessary to measure the depth and diameter of the pile hole to ensure that the pile hole meets the construction standards.

[0003] The existing pile hole measuring devices mainly have the following disadvantages in the process of use: one device can only measure one value of the pile hole, and multiple devices need to be combined to obtain data such as the depth and diameter of the pile hole, which is more troublesome, time-consuming and laborious, and the measuring efficiency is relatively low. Therefore, there is room for improvement. Summary of the Invention

Detailed implementation manners

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments may be combined with each other.

[0023] Some embodiments of the present utility model will be described below with reference to the accompanying drawings. Embodiment 1:

[0024] Combined with Figures 1-4 As shown, this embodiment provides a construction engineering measuring device, including: a main body mechanism 100.

[0025] Among them, the main body mechanism 100 includes a pipe body 110, multiple groups of bases 120 fixed on the outer side surface of the pipe body 110, a measuring rod 130 whose end is rotatably installed on the base 120, an angle sensor 140 installed on one side of the base 120 and connected to the end of the measuring rod 130, a positioning rod 150 movably arranged in the inner cavity of the pipe body 110 and extending out of the pipe body 110, a distance sensor 160 installed on the inner wall of the positioning rod 150, and a display screen 170 installed on the outer side surface of the pipe body 110.

[0026] The pipe body 110 is used to install other components, the base 120 is used to install the measuring rod 130, two bases 120 are set as a group, the measuring rod 130 includes a rotating seat 131 whose end is rotatably installed on the base 120, springs 132 sleeved on both sides of the rotating seat 131, a support rod 133 whose one end is fixed on the rotating seat 131, and a sphere 134 fixed on the end of the support rod 133. Circular grooves are formed on the inner side surfaces of the opposite bases 120, the end of the rotating seat 131 is rotatably fitted in the circular groove, and at the same time, one side of the spring 132 is fixed on the end of the rotating seat 131, and the other side is fixed to the inner wall of the circular groove, so that the rotating seat 131 rotates to one side, that is, the support rod 133 unfolds outward and presses against the inner wall of the pile hole. When the pipe body 110 is located in the pile hole, under the action of the spring 132, the support rod 133 is driven to unfold outward, so that the sphere 134 presses against the inner wall of the pile hole, and the three measuring rods 130 press against the inner wall of the pile hole to ensure that the pipe body 110 is on the center line of the pile hole.

[0027] The angle sensor 140 is used to detect the angle of rotation of the rotating seat 131, that is, the inclination angle R of the support rod 133 relative to the central vertical line of the rotating seat 131. The length of the support rod 133 is the distance S1 between the center of the rotating seat 131 and the center of the sphere 134. According to the sine theorem, given the length S1 of the support rod 133 and the rotation angle R, the distance S2 between the end of the support rod 133 and the center point of the rotating seat 131 can be calculated, that is, the distance between the vertical line of the center of the sphere 134 and the central vertical line of the rotating seat 131. The distance between the central vertical line of the rotating seat 131 and the center line of the pipe body 110 is S2, and the radius of the sphere 134 is S3. By adding the distance S2 between the end of the support rod 133 and the center point of the rotating seat 131, the distance S2 between the central vertical line of the rotating seat 131 and the center line of the pipe body 110, and the radius S3 of the sphere 134, the radius of the pile hole can be calculated and transmitted to the display screen 170 for display, which is convenient for the surveyors to obtain.

[0028] The positioning rod 150 includes a sliding seat 151 movably arranged in the inner cavity of the pipe body 110 and side plates 152 fixed on both sides of the sliding seat 151 and extending out of the pipe body 110. The sliding seat 151 is slidably fitted in the inner cavity of the pipe body 110 for installing the side plates 152 and moving synchronously with the side plates 152. Through holes 111 are opened on both sides of the pipe body 110, and the side plates 152 pass through the through holes 111 and extend out to limit the movement of the side plates 152 and ensure the stability of the side plates 152 when moving up and down.

[0029] A groove is opened at the bottom end of the sliding seat 151, and the distance sensor 160 is installed on the inner wall of the groove. During measurement, the bottom end of the pipe body 110 is pressed against the inner bottom wall of the pile hole. At this time, both sides of the side plate 152 are pressed against the ground on both sides of the pile hole. The distance sensor 160 detects the distance between it and the inner bottom wall of the pipe body 110, which is the depth of the pile hole, and transmits it to the display screen 170 for display, which is convenient for people to obtain information.

[0030] Working principle and usage process of the present utility model: During use, the pipe body 110 is placed into the pile hole combination, and the bottom end of the pipe body 110 is tightly attached to the inner bottom wall of the pile hole. Due to the effect of the spring 132, the rotating seat 131 is driven to rotate to one side, that is, the support rod 133 is driven to expand outwards, so that the sphere 134 is tightly attached to the inner wall of the pile hole. The three measuring rods 130 are simultaneously tightly attached to the inner wall of the pile hole to ensure that the pipe body 110 is on the central vertical line of the pile hole. At this time, the angle sensor 140 detects the rotation angle of the rotating seat 131, that is, the inclination angle of the support rod 133. According to the sine theorem, given the length and rotation angle of the support rod 133, the distance between the end of the support rod 133 and the center point of the rotating seat 131 can be calculated, that is, the distance between the vertical line of the center point of the sphere 134 and the vertical line of the rotating seat 131. Adding the sum of these three distances, the radius of the pile hole can be calculated and transmitted to the display screen 170 for display. At the same time, when the bottom end of the pipe body 110 is tightly attached to the inner bottom wall of the pile hole, both sides of the positioning rod 150 are tightly attached to the ground. At this time, the distance sensor 160 detects the distance between it and the inner bottom wall of the pipe body 110, and the depth of the pile hole can be measured and transmitted to the display screen for display.

[0031] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
