Description
Technical Field
The utility model relates to a high detection device that meets an emergency, concretely relates to high detection device that meets an emergency of accurate location.
Background
The high strain detection is a detection method for judging the vertical compression bearing capacity and the integrity of a pile body of a single pile, a heavy hammer is used for impacting the pile top in an experiment, the speed and force time-course curve of the pile top are measured in an actual mode, and the speed and force time-course curve is analyzed through a fluctuation theory.
When detecting the quality of pile foundation engineering, a high-strain dynamic detection method is generally adopted to detect the vertical compressive bearing capacity and the structural integrity of a pile body of a foundation pile in a pile foundation. In the detection process by adopting the high-strain dynamic detection method, technicians need to excavate a pile head of the foundation pile, and install the acceleration sensor and the strain type force sensor used by the high-strain dynamic detection method on the side surface of the pile with the distance of twice the diameter of the foundation pile from the pile top.
In the process of detection, the problem that the counter weight and the foundation pile cannot be aligned usually exists, so that the measurement is inaccurate, and in addition, only one middle lifting hook is usually arranged in the lifting process of the detection device, so that the counter weight is stressed unevenly when being hit.
Disclosure of Invention
The utility model aims at providing a high detection device that meets an emergency of accurate location solves the problem of the unable centering that exists in the high detection of meeting an emergency of foundation pile.
The utility model adopts the following technical scheme:
the high strain detection device with the accurate positioning function comprises a cylindrical hammer body and a lifting piece, wherein the lifting piece is connected with the hammer body and used for lifting the hammer body, a hollowed circular hole is formed in the longitudinal central line of the hammer body, four lifting hooks are uniformly arranged on the outer circumference of the upper surface of the hammer body, the lifting piece comprises a U-shaped ring and a wire rope connected with the U-shaped ring, the wire rope penetrates through the U-shaped ring, and two ends of the wire rope are respectively fixed on two opposite lifting hooks; the upper surface of the hammer body is provided with a level meter used for adjusting the levelness of the hammer body, and a protective shell is arranged outside the level meter.
Above technical characteristic, the centre of hammer block is provided with the fretwork round hole, and the personnel of being convenient for carry out the centering, do benefit to the accuracy that detects evenly set up the lifting hook on the outer circumference of the upper surface of hammer block, guarantee the parallelism of atress, it is more accurate to test be provided with the spirit level that is used for adjusting the hammer block levelness on the upper surface of hammer block, the equilibrium of confirmation hammer block upper surface that can be more accurate further ensures the measuring accuracy.
Furthermore, a lifting rope buckle is arranged at the joint of the wire rope and the hammer body lifting hook and used for adjusting the length of the wire rope and ensuring the lifting balance.
Furthermore, the joint of the U-shaped ring and the wire rope is provided with a non-slip mat to prevent the hammer body from inclining.
The beneficial effects of the utility model reside in that: 1. the device is mainly used for detecting high-strain pile foundations, has a simple structure and low manufacturing cost, and is easy to realize field manual centering and leveling compared with a conventional heavy hammer with only 1 hanging ring.
2. And a user can center the pile top of the pile to be measured below the user through a centering hole reserved in the center of the hammer. Traditional counter weights are all solid weights and cannot achieve functions.
3. The upper surface of the hammer is provided with 4 hanging noses which are connected with the hammer in a penetrating way, and the lower end of the hanging noses is fixed by a screw cap. After two adjacent hanging noses are connected by a steel wire rope, the length of the hanging noses can be adjusted, and therefore the leveling of the hammer body is achieved.
4. When the hammer body is slightly uneven or the pile top is not horizontal, the fine adjustment can be carried out by moving the steel wire rope to the high side.
