Construction platform for facilitating root key construction of root type cast-in-place pile

Abstract

The invention discloses a construction platform for facilitating root key construction of a root type cast-in-place pile. The construction platform for facilitating the root key construction of the root type cast-in-place pile comprises a base plate; the positions, corresponding to root key limiting devices, of the bottom of the base plate are respectively and rotatably connected with transmission gears; the transmission gears are respectively in transmission connection with respective driving motor; the transmission gears are in engaged transmission with vertical gear racks at the tail ends of the root keys which are inserted into the side wall of a pile pit. From the above structure, the construction platform for facilitating the root key construction of the root type cast-in-place pile disclosed by the invention can climb in the pile pit automatically so as to complete the construction of all root keys in the pile pit without external force, so that the construction efficiency of the root keys is improved.

Description

technical field [0001] The invention relates to the technical field of construction of root-type cast-in-place piles, in particular to a construction platform for root key construction of root-type cast-in-place piles. Background technique [0002] In the field of construction, pile foundations are usually used for bearing pressure, and pile foundations bear pressure through the joint action of pile side resistance and pile end resistance. The bearing capacity of the pile foundation is related to the resistance provided by the pile side and pile end. By increasing the diameter of the pile foundation or the length of the pile foundation, that is, by increasing the stressed area, the pile side resistance or pile end resistance of the pile foundation can be improved. , thereby increasing the bearing capacity of the pile foundation. However, in actual construction, the longer the pile foundation is, the more difficult the construction is; the larger the diameter of the pile fou...

AI Technical Summary

Problems solved by technology

[0004] First, during the entire construction process, hoisting devices are required, resulting in very high construction costs

[0005] Second, the construction is carried out in the hoisting state. Although the suspension rod has been used instead of the suspension rope to improve a certain rigidity, there will still be shaking, which is a great safety hazard during the construction process.

[0006] Third, the part that pushes the root key into the side wall of the pile pit is a slope structure. When the slope structure acts on the root key, it will produce a vertical force at the same time, and push the root key into the side of the pile pit. When the wall is closed, the root key cannot be guaranteed to be jacked horizontally, and the construction quality of the root key cannot be guaranteed

[0007] Fourth, the number of root keys in the same layer is greatly affected by the number of slopes at each angle, and the volume occupied by the slopes is relatively large, resulting in a limited upper limit on the number of slopes

[0008] Fifth, due to the large mention of the slope surface and the need to bear a certain pressure, the weight of the slope surface is relatively large, which increases the load of hoisting, resulting in higher requirements for the load-bearing capacity of the crane required, which further increases the construction cost
