Disclosed are an informatization technology pile pouring structure and a pile structure, the pile pouring structure comprising a reinforcement cage, a position-limiting ring that is mounted at the exterior of the reinforcement cage, a plurality of PVC pipes that are provided inside of the reinforcement cage, a cut-off layer that is provided on the position-limiting ring, and a two-dimensional code display board that is provided in one-to-one correspondence with the reinforcement cage. The cut-off layer is annular. A two-dimensional code, which is scanned to then enter an information input interface, is provided on the two-dimensional code display board. The beneficial effects of the present invention are: the present solution, by means of scanning a two-dimensional code to input strength information of a pile body, achieves informatization management for a pile construction process, which helps to improve the operation efficiency; the cut-off layer is used as the boundary surface between the pile body and a pile head, thereby rapidly positioning a part requiring removal; and by removing the pile head at the upper part of the cut-off layer, the cut-off layer can protect the structure at the lower part, thus reducing the damage to the part below the cut-off layer during the removal process.
A: Disclosed are a vehicle information querying method and system and a storage medium. The method comprises: a vehicle information management system receiving a barcode scanning instruction when a smart user terminal scans a two-dimensional barcode, the two-dimensional barcode comprising identity information of the vehicle; querying, according to two-dimensional barcode information in the barcode scanning instruction of the smart terminal, the system for detailed information of the vehicle; and pushing the obtained detailed information of the vehicle to an application interface of the smart terminal for display. The code scanning operation of the present invention allows a user to quickly search for detailed information of a vehicle, simplifies user operation, and improves the user experience.
B: Disclosed in the present invention is a grouting valve at the bottom of a cast-in-place pile for geotechnical engineering construction, comprising a main cylinder, a first connection sleeve, a first connection cylinder, secondary cylinders, a second connection sleeve, a second connection cylinder, and adjustment assemblies. The lower part of the first connection cylinder is provided with first discharge holes; the lower part of the second connection cylinder is provided with fifth discharge holes; each adjustment assembly comprises a mounting frame, a first connection shaft, a second connection shaft, first connection rods, second connection rods, third connection rods, first mounts, fourth connection rods, fifth connection rods, sixth connection rods, and second mounts; the second connection rods are disposed on the first mounts; the first mounts are disposed on the secondary cylinders; the fifth connection rods are disposed on the second mounts; the second mounts are disposed on the main cylinder; and the main cylinder and the secondary cylinders are each provided with a driving mechanism for driving two parallelogram mechanisms to rotate so that the main cylinder and the secondary cylinders move toward or away from each other. The present invention can be used for grouting on both inner and outer sides of a steel cage, such that the grouting is more uniform, and the speed is faster.
C: Disclosed are a POS machine capable of changing the direction of scanning a two-dimensional code and a usage method therefor. The POS machine capable of changing the direction of scanning a two-dimensional code comprises a POS machine body. The POS machine body comprises a front-facing camera provided on an upper portion of a liquid crystal display screen. The front-facing camera is provided with a right-angled triangle prism with an exterior structure, wherein same can enter a two-dimensional code into the camera after two instances of total reflection, such that the front-facing camera can scan the two-dimensional code, which is not required to be placed directly above the camera. The present apparatus has a simple structure and is convenient for the usage habits of a user.
D: A joint of a concrete-filled steel tube column and an annular steel plate concrete beam, comprising a concrete-filled steel tube column (1), an annular steel plate concrete beam (2), and a reinforced concrete frame beam (3). The annular steel plate concrete beam (2) comprises a steel plate (8) and a steel reinforced cage; concrete slurry passage holes (12) are formed in the middle of the steel plate (8); the steel plate (8) and the steel reinforced cage are annular, the annular steel plate (8) and the steel reinforced cage is coaxially arranged; the annular steel plate concrete beam (2) is sleeved on the outer side wall of the concrete-filled steel tube column (1); one end of the reinforced concrete frame beam (3) extends into the annular steel plate concrete beam (2); stressed steel bars (11) of the reinforced concrete frame beam (3) are connected to the steel plate (8); the annular steel plate concrete beam (2) is a centrally symmetrical annular or eccentric annular structure. According to the joint, the stressed steel bars (11) of the reinforced concrete frame beam (3) are anchored by the steel plate (8), so that the seismic performance of the connecting joint is ensured. The present invention also relates to a construction method for a joint of a concrete-filled steel tube column and an annular steel plate concrete beam.
