Description

Technical Field

[0001] The utility model relates to the technical field of building detection devices, in particular to a prefabricated pipe pile inclination detection device. Background Art

[0002] Pile foundation is a common foundation structure in construction projects. It is mainly used to bear the load of the superstructure and transfer it to the deep soil layer. Different types of piles can be selected according to different needs and geological conditions. Common types of piles include prefabricated pipe piles, cast-in-place piles, bored cast-in-place piles, etc. Prefabricated pipe piles are made in the factory in advance. They have the advantages of stable quality, no influence from the on-site environment, convenient construction, and can greatly shorten the construction period. Therefore, they are widely used in engineering.

[0003] Usually, the main ways to inject prefabricated pipe piles are static pile pressure and hammer pile sinking. In actual operation, the pile body may tilt due to poor geological conditions, improper installation of the pile driver, the pile frame not being perpendicular to the ground, lax verticality control during the pile driving process, rust or deformation of the steel sheet pile connection lock, which causes the pipe pile to fail to smoothly go down along the lock or the pile resistance is too large. Therefore, whenever the pile foundation construction is completed, the integrity, bearing capacity and inclination rate of the pile body must be tested, otherwise it will cause additional bending moment and shear force in the building, reduce the bearing capacity of the pile foundation, and thus affect the safety and stability of the pile foundation.

[0004] At present, most of the detection methods used include manual observation. Operators use levels or inclinometers, hanging ball plumb method and other methods to conduct detection. However, manual detection not only requires the cooperation of at least two people, but also due to the large errors in manual operation and observation, sometimes even detection errors occur. Therefore, relying on manual detection has major problems and affects the quality of the building. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] Please refer to Figure 1 , a prefabricated pipe pile inclination detection device provided by the utility model comprises an annular leveling platform 1, a telescopic support foot 2 is provided on the lower surface of the annular leveling platform 1, a measuring ruler 3 is detachably connected to the upper surface, and the inner side of the measuring ruler 3 and the leveling platform 1 are perpendicular to each other. The telescopic support foot 2 is used to support the annular leveling platform 1 and place it on the ground, and the measuring ruler 3 is in contact with the prefabricated pipe fitting 5. By calculating the angle between the measuring ruler 3 and the prefabricated pipe fitting 5, the inclination of the prefabricated pipe fitting 5 can be detected. The measuring ruler 3 is a right triangle ruler.

[0030] Please refer to Figure 2 and Figure 3The annular leveling platform 1 includes an annular body 11, which is a closed annular table with a certain thickness and width. The material should be stainless steel or other materials with a certain weight to ensure stability when placed on the construction site. The shape of the annular leveling platform 1 can be a ring or other closed rings. This application uses a ring, but there is no limitation to this.

[0031] The upper surface of the circular leveling platform 1 is centered at its center, and there are four calibration slots 12 in a circular equidistant array, which are opened from the outer edge of the circular leveling platform and extend to the inner edge of the circular leveling platform, and the extension direction is always toward the center of the circular leveling platform 1. When in use, the four calibration slots 12 are respectively aligned with the four directions of the horizontal plane.

[0032] At least one bubble level 5 is provided on the annular leveling platform 1. The bubble level 5 is used to measure the horizontality of the annular leveling platform 1. The bubble level 5 can be a tube level or a circular level, or both a tube level and a circular level can be provided. The tube level is used for precise measurement, and the circular level is used for rough measurement. The selection can be made according to actual needs. Specifically, a groove is provided on the surface of the annular leveling platform 1, and then the tube level or the circular level is installed in the groove.

[0033] Please refer to Figure 2 and Figure 4 The telescopic support foot 2 is arranged below the annular leveling platform 1 and can be connected by welding or screwing. The telescopic support foot 2 includes an outer tube body 21, and an inner rod body 22 is plugged and connected in the outer tube body 21. The length of the inner rod body 22 is smaller than the outer tube body 21. The inner rod body 22 is arranged in the outer tube body 21 by friction. The inner rod body 22 can be pushed to telescope in the outer tube body 21 by applying external force, so that the adjustment in use can be achieved.

[0034] The outer tube body 21 has a strip hole 23 on its surface, and the length of the strip hole 23 is determined by the length of the outer tube body 21. In this embodiment, the length of the strip hole 23 is four fifths of the length of the outer tube body 21. The inner rod body 22 can be pushed to move through the strip hole 23.

[0035] In order to further increase stability, a fastening nut 6 is provided on one side of the outer tube body 21 , and the end of the fastening nut 6 passes through the outer tube body 21 and abuts against the inner rod body 22 , thereby enhancing the friction between the outer tube body 21 and the inner rod body 22 and improving the stability of the telescopic support foot 2 .

[0036] In addition, a block 24 is provided at the lower part of the inner rod body 22, and the block 24 is fixedly connected to the inner rod body 22. The block 24 can prevent the inner rod body 22 from being inserted deeper than its own length, causing the annular leveling platform 1 to overturn, or the inner rod body 22 to be difficult to remove.

[0037] Working principle:

[0038] Please refer to Figure 5 and Figure 6 When using the prefabricated pipe pile inclination detection device, two mutually orthogonal horizontal directions should be selected. Generally, due east can be set as the positive direction of X and due north as the positive direction of Y. The calibration slots 12 opened on the circular leveling platform 1 are intersected with the axis direction respectively. After the instrument is set up and leveled, the measuring ruler 3 is placed in the grooves C1, C2, C3, and C4 of the circular leveling platform respectively. The horizontal distance W and the vertical distance H of the prefabricated pipe pile 5 from the circular leveling platform 1 are measured by the measuring ruler 3 respectively, and the inclination angle at a certain point is calculated using the tangent function formula (1).

[0039]

[0040] The average inclination in the X direction is calculated according to the following formula (2):

[0041]

[0042] The average slope in the y direction is calculated by the following formula (3):

[0043]

[0044] The overall inclination of the prefabricated pipe pile 5 is calculated by the vector addition method, as shown in formula (4).

[0045]
