Embodiment 1

[0043] Please also refer to Figure 1 to Figure 3 Now, a specific implementation of a caisson with adjustable sinking friction resistance provided by the present invention will be described. This sinking friction adjustable caisson includes a well body 1, a friction adjustment unit and a data collector, wherein the well body 1 includes a well wall 11 with several openings 111 around it; the friction adjustment unit is arranged at the opening 111, And corresponding to the opening 111 one by one, the friction adjustment unit includes the driver 2 connected to the well body 1, the telescopic member 3 connected to the driver 2, the telescopic member 3 is slidably connected to the well body 1 through the opening 111, and the driver 2 is used to extend the telescopic The part 3 is pushed out of the well wall 11 or retracted into the well wall 11; the data collector is arranged on the well body 1 and is electrically connected with the driver 2, and is used for collecting the attitude...

Embodiment 2

[0047] As a specific implementation of the embodiments of the present invention, please refer to Figure 1 to Figure 9 , the structure of a caisson with adjustable sinking friction resistance provided by this embodiment is basically the same as that of Embodiment 1, the difference is that the driver 2 is detachably connected to the well body 1, and the driver 2 includes a connecting piece 21, a telescopic adjuster 22 and an angle regulator 23, wherein the connector 21 is detachably connected to the well body 1; one end of the telescopic regulator 22 is fixedly connected to the connector 21 and is arranged in the opening 111; one end of the angle regulator 23 is connected to the telescopic regulator 22 The other end is connected, and the other end is connected with the telescopic part 3 for adjusting the angle of the telescopic part 3. The connecting piece 21 can be a rectangular plate, which can be detachably connected to the well body 1 through bolts; the telescopic adjuster ...

Embodiment 3

[0055] As a specific implementation of the embodiments of the present invention, please refer to Figure 1 to Figure 10 , the structure of a caisson with adjustable sinking friction resistance provided by this embodiment is basically the same as that of Embodiment 2, the difference is that it also includes a fixing part 4 detachably connected with the well body 1, and the fixing part 4 passes through the opening 111 It runs through the well wall 11 and is a strip-shaped structure, which is used for fixedly connecting the well body 1 with the soil layer. When the well body 1 sinks to the design elevation, the friction adjustment unit is removed, and the fixing member 4 is fixed into the soil layer through the opening 111 to support and fix the well body 1 to prevent the well body 1 from sinking or shifting. At the same time, the frictional resistance adjustment unit can be applied to other well bodies 1 for recycling, which saves cost and has a higher utilization rate.

Abstract

The invention discloses an open caisson with sinking frictional resistance adjustable. The open caisson comprises a caisson body, frictional resistance adjusting units and data collectors, wherein the caisson body comprises a caisson wall, and a plurality of openings are formed in the periphery of the caisson wall; the frictional resistance adjusting units are arranged at the openings and correspond to the openings in a one-to-one mode; each frictional resistance adjusting unit comprises a driver connected to the caisson body and a telescopic part connected to the driver; the telescopic parts are slidably connected to the caisson body through the openings; the drivers are used for pushing the telescopic parts out of the caisson wall or retracting the telescopic parts into the caisson wall; and the data collectors are arranged on the caisson body, electrically connected to the drivers and used for collecting the posture and sinking data of the caisson body. According to the open caisson with the sinking frictional resistance adjustable, the sinking resistance is properly adjusted and controlled through the frictional resistance adjusting units arranged at different positions, and the problems that in the prior art, deviation exists in the sinking amount of different parts in the open caisson construction period, the posture of the open caisson deviates, and even sinking cannot be achieved or sudden sinking occurs are solved. The open caisson with the sinking frictional resistance adjustable has obvious effect and is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a caisson with adjustable sinking friction resistance. Background technique [0002] The caisson is a well-shaped structure. When soil is excavated in the well, the caisson relies on its own gravity to overcome the friction of the well wall and then sinks to the design elevation. Then, it is sealed with concrete and the well hole is filled to make it a bridge pier or other structures. Foundation. It is used in the construction of foundation pits of large bridge piers, sewage pumping stations, large equipment foundations, civil air defense shelters, shield assembly wells, underground lanes and station hydraulic foundation construction enclosures. [0003] During the construction of the caisson, due to the uncertainty of the formation and construction, it is easy to cause deviations in the amount of subsidence in different parts, resulting in a deviation of the caiss...
