Problems solved by technology

[0004] Although the above method is easy to operate and has low equipment requirements, it has been widely used in actual engineering, but due to its low precision and insufficient information feedback on possible problems, it is not necessary for some holes and piles to meet the quality requirements. Higher measured holes show insufficient reliability

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as figure 1 and 2 As shown, an inclination-type aperture testing device is used for detecting the aperture size along the depth direction of rotary excavation, drilling and impact hole piles. The test device includes a central rod 1, a radially extending beam 2, an adjustable section 3 of the extending beam, a positioning bolt 4, an aperture adaptive rod 6, a pulley 7, and a torsion spring 8. The central pole 1 is used as the suspension structure of the whole device, and its top can be connected with a suspension rope. The interior is hollow as the installation position of electrical components such as roll sensors and circuits. The waterproof function can be realized after the cavity is sealed. The bottom of the central rod 1 is set as a tip, and when the device sinks to the bottom of the hole, the bottom sediment can be inserted...

Abstract

The invention discloses an inclination type aperture measuring device and a method thereof. The device comprises a center rod, a plurality of couples of radial extending beams, extending beam adjustable sections, positioning bolts, aperture self-adapting rods, pulleys and torsion springs; the radial extending beams are fixed to the center rod symmetrically, each couple of the radial extending beams are distributed at two sides of the center rod and located in the same line, and a side-incline sensor is carried in the center rod; the corresponding extending beam adjustable section is arranged at the end, far from the center rod, of each radial extending beam, the aperture self-adapting rods are hinged to the extending beam adjustable sections, and the torsion springs used for exerting external expansion force to the aperture self-adapting rods are arranged at the hinging parts; and the pulleys are arranged at the tail ends of the aperture self-adapting rods which carry the side-incline sensors. The inclination type aperture measuring device is simple in structure, can be subjected to waterproof sealing easily, can achieve durable use of equipment and has good equipment reliability. According to the device, operation is easy, the size of the device is small, the radial extending beams are adjustable, and the device has considerable project adaptability and promotional value.

Description

technical field [0001] The invention belongs to the field of construction methods, and in particular relates to an inclination-type aperture testing device and a method thereof. The device can realize the detection of the aperture size along the depth direction of rotary excavation, drilling and impact hole-forming piles, and provides support for hole-forming quality analysis . Background technique [0002] With the continuous development of pile foundation construction technology, more and more attention has been paid to the quality control of pile foundation piles. At present, the bored piles are widely used in actual engineering, and the quality control of the pile body mainly includes the quality control of the hole and the quality control of the pile. Among them, the method of pile body quality control and the quality inspection technology after pile formation have made great progress, and have obtained quite a lot of engineering practice tests, while the control and d...
