Embodiment Construction

[0017] (1) The conduit for conveying concrete is formed by connecting multiple conduit units in sequence. The upper end of each conduit unit is provided with internal threads, and the lower end of each conduit unit is provided with external threads. The lower end of the first conduit unit 1 is connected to the second conduit unit. The upper end of the unit is threaded, so that multiple conduit units are connected in turn to form a conduit. An upper ring gear 3 is installed on the upper end of each conduit unit, and a lower ring gear 4 is installed on the lower end of each conduit unit. An axial bearing is arranged under the ring 4;

[0018] (2) A supporting platform 8 is set above the pile foundation. The supporting platform 8 is exactly a working surface for supporting. A circular hole suitable for the conduit is set on the supporting platform 8. Axial bearings are supported on the support platform 8, the so-called first section of conduit unit 1 is the uppermost section, so ...

Abstract

The invention provides a pile foundation concrete pouring method comprising the following steps: a guide pipe for conveying concrete is formed by connecting a plurality of guide pipe units successively, a funnel is arranged on the upper end of the first guide pipe unit and a one-way vane is arranged in the last guide pipe unit; a support platform is arranged above a pile foundation and a support frame is installed, and an upper gear, a lower gear, a motor and a speed reducer are arranged on the support frame; the motor is started to drive the guide pipe to rotate, and mixed concrete is poured into the funnel and slides downward along the one-way rotating vane to be conveyed to the pile foundation; after a certain height is reached, the funnel is detached, the guide pipe is lifted up for the height of a guide pipe unit by a crane and the second guide pipe unit is supported on the platform; the first guide pipe unit is detached and then the funnel is again installed for pouring; the steps are repeated for completing the pouring. Rotation of the guide pipe makes concrete fall down smoothly; the one-way vane achieves buffering and mixing effects on the concrete, so that the phenomenon of pile breaking caused by concrete disintegration.

Description

technical field [0001] The invention relates to a pile foundation concrete pouring method, which belongs to the field of construction engineering. Background technique [0002] At present, the construction of bored piles usually adopts the procedures of drilling, clearing holes, installing steel cages, and pouring concrete. In the process of pouring concrete, the conduit pouring method is usually used to link the conduits in sequence, and a funnel is placed on the top conduit to carry out the concrete. For pouring, if the pile foundation is deep, the falling height of the concrete will be far greater than 10m during the falling process. If the falling height is too high, the concrete will segregate during the falling process. The occurrence of segregation will indirectly change the concrete mix ratio and seriously affect the quality of the pile foundation. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide ...
