Description

Technical Field

[0001] The utility model relates to the field of construction engineering, and more specifically to a pile foundation inclination detection device. Background Art

[0002] A deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation consisting of a column connected to the pile base, is referred to as a pile foundation. If the pile is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low-cap pile foundation. If the upper part of the pile is exposed above ground and the bottom of the cap is above ground, it is called a high-cap pile foundation.

[0003] Pile foundations require drilling holes in the ground beforehand. The verticality of the pile foundation hole determines the quality of the subsequent pouring of the pile foundation, so the inclination of the pile foundation hole needs to be tested during pouring. Existing techniques often use ultrasonic detectors for testing. The device is placed at the center above the pile foundation hole, and then the ultrasonic probe is slowly lowered into the pile foundation hole to perform the test. However, due to the large amount of mud and water accumulated inside the pile foundation hole, the signal line of the probe will adhere to the mud and water during testing. If not cleaned in time, a large amount of stains will drip onto the surface of the equipment. At the same time, the stains will also corrode the surface of the connecting line, affecting the service life of the equipment. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] Example:

[0020] See also Figure 1 and Figure 2 As shown, a pile foundation inclination detection device includes a transverse support frame 1, which spans above the pile foundation hole. When preventing the transverse support frame 1, it is necessary to ensure that the through hole 9 is placed in the center of the pile foundation hole to ensure that the ultrasonic probe 8 falls along the axis of the pile foundation hole. A connecting plate 5 is provided in the center of the transverse support frame 1, and brackets 6 are symmetrically provided on the upper surface of the connecting plate 5. A wire drum 7 is provided between the two brackets 6 for rotation through a bearing. The wire drum 7 is suspended in the air, and the suspended state is convenient for retracting and releasing the connecting wire 71. The surface of the wire drum 7 is evenly wound with the connecting wire 71. A through hole 9 is provided in the center of the connecting plate 5 to ensure that the wire can only be released along the center position when releasing the wire, so that the ultrasonic probe 8 is always in the center of the pile foundation hole. The connecting wire 71 passes through the through hole 9. The bottom end of the connecting wire 71 is provided with an ultrasonic probe 8. The other end of the connecting wire 71 is connected to the instrument. The ultrasonic probe 8 emits ultrasonic waves for detection, and the signal is transmitted to the instrument through the connecting wire 71 to realize dry detection.

[0021] Please refer to Figure 3 and Figure 4 As shown, an extension bolt 10 is provided on the front side of the bottom of the connecting plate 5, and movable rods 11 are symmetrically installed on the surface of the extension bolt 10 through bearings. The two movable rods 11 can rotate along the axis of the extension bolt 10, and then adjust the angle between the two. The two movable rods 11 are respectively placed on both sides of the through hole 9. A rubber scraper 12 is provided on the inner side of the movable rod 11. The rubber scraper 12 is semicircular, and the inner arc of the rubber scraper 12 is adapted to the connecting line 71. By controlling the angle of the two movable rods 11 to control whether the rubber scrapers 12 on both sides are in contact with the surface of the connecting line 71, the sewage on its surface can be scraped off when the line is taken up.

[0022] Among them, a tension spring 13 is connected between the two movable rods 11, and the tension of the tension spring 13 is used to make the two movable rods 11 have the force to approach each other. A boss 14 is provided on the side where the two movable rods 11 are close to each other, and an adjusting bolt 15 is threaded through the corresponding boss 14 of the connecting plate 5. An extrusion head 16 is provided at the bottom of the adjusting bolt 15, and the extrusion head 16 is placed under the connecting plate 5. The extrusion head 16 contacts the two bosses 14 respectively. Screwing the adjusting bolt 15 can control the up and down movement of the extrusion head 16. The extrusion head 16 has a conical structure. When the conical extrusion head 16 moves downward, it can squeeze the bosses 14 on both sides, so that the angle of the two movable rods 11 increases. At this time, the inner walls of the rubber scrapers 12 on both sides do not contact the connecting line 71. When the extrusion head 16 returns to move upward, the tension of the tension spring 13 can be used to make the two rubber scrapers 12 close to each other, so as to scrape off the mud and water on the surface of the connecting line 71.

[0023] Please refer to Figure 1As shown, movable frames 2 are symmetrically slidably installed at both ends of the transverse support frame 1. The movable frame 2 has a U-shaped structure. Locking bolts 4 are symmetrically screwed on the ends of the transverse support frame 1. The locking bolts 4 fix the two sides of the movable frame 2. The movable frames 2 on both sides are moved horizontally to adapt to pile foundation holes of different diameters and are fixed by locking bolts 4. A stopper 3 is provided under the end of the movable frame 2 away from the transverse support frame 1. When installed, the stopper 3 is symmetrically placed on both sides of the pile foundation hole to ensure the stability of the equipment during detection and prevent deviation when laying out the line.

[0024] Working principle: According to the size of the pile foundation hole, the positions of the movable frames 2 on both sides are adjusted so that the stop blocks 3 on both sides are respectively placed on both sides of the pile foundation, so as to facilitate the adjustment of the ultrasonic probe 8 to the center position of the pile foundation hole, and then the end of the connecting line 71 away from the ultrasonic probe 8 is connected to the detector, and the ultrasonic probe 8 is lowered. The pile foundation hole is detected by the ultrasonic wave emitted by the ultrasonic probe 8. At the same time, due to the presence of the tension spring 13, the movable rods 11 on both sides have a force to approach each other, so that the bosses 14 on both sides always keep in contact with the conical surface of the extrusion head 16. When paying out the line, the extrusion head 16 can be rotated downward to squeeze and separate the two movable rods 11. Conversely, when taking up the line, the adjustment bolt 15 is screwed up to move the extrusion head 16 upward. At this time, the presence of the tension spring 13 is used to make the movable rods 11 on both sides close to each other, and the two rubber scrapers 12 are in slight contact with the surface of the connecting line 71. When the rotating wire drum 7 is taken up, the rubber scrapers 12 on both sides can be used to scrape off the moisture and sludge on the surface of the wire drum 7 to ensure the cleanliness of the surface of the connecting line 71.

[0025] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
