[0002] In the field of construction, as the height and volume of the main structure continue to increase, bored piles are widely used due to their small settlement and high bearing capacity. The quality of concrete pouring is one of the key points for the quality of bored piles. , the traditional method uses the drilling frame of the engineering drilling rig or a small crane to lower and lift the conduit for concrete pouring operations. This method will affect the utilization rate of on-site machinery, reduce work efficiency, and increase project costs.
If a small crane is used for pouring, it may cause uneven speed when the concrete pipe is lifted, which will affect the quality of the pile and the cost will be high

Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings of the description.
[0020] Such as Figure 1-4 As shown, a concrete pouring device for bored piles with mud retaining walls includes a chassis 1, a frame 2, a hoist 3, a hoisting system 4, a hopper 5, and a conduit 6. It is characterized in that: the frame 2 is connected to the chassis through a pin 1 connection, the outlet at the bottom of the hopper 5 is connected to the upper end of the conduit 6, and the hopper 5 is lifted and lowered through the hoisting system 4 connected to the frame 2.
[0021] The steel chassis 1 is welded by section steel, and the hoist 3 is fixed on the section steel cross brace in the middle of the chassis 1 by bolts.
[0022] The frame 2 includes a portal hanger 7, a brace 8 and a fixed pulley 9. The upper end of the brace 8 is connected to the upper part of the vertical rod 15 of the portal hanger 7 through a pin, and the lower end of the...

The invention discloses a slurry protection wall bored pile concrete casting device, which comprises a base plate, a stander, a winch, a hoisting system, a hopper and a guide pipe. The slurry protection wall bored pile concrete casting device is characterized in that: the stander is connected with the base plate through a bolt pin; the material outlet at the bottom of the hopper is connected withthe upper end of the guide pipe; and the winch drives the hopper and the guide pipe to be lifted or descended through the transmission of the hoisting system. The slurry protection wall bored pile concrete casting device has the advantages that: (1) the site construction can be performed continuously so that a poring machinery and a concrete casting machinery cannot be used together to fulfill the aim of special machinery for special use; (2) the severe quality problems, such as pile breakage caused by overlarge up-pull degree of the guide pipe can be avoided; (3) the device is easy adj convenient to manufacture; (4) the slurry protection wall bored pile concrete casting device can be reused and is convenient to transport; and (5) the engineering cost is lowered.
