Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
As shown in fig. 1 and 2, the deep foundation pit concrete pouring chute comprises an enclosure structure steel sheet pile 3, a primary chute 4 and a secondary chute 5; the one-level chute 4 is connected with the enclosure structure steel sheet pile 3 through the snap ring, the one-level chute 4 can rotate from top to bottom along the snap ring joint, the second-level chute 5 is connected with the one-level chute 4 through the rotating shaft assembly, and the second-level chute 5 can rotate 360 degrees along the horizontal plane of the joint.
As a modification of the embodiment, the rotating shaft assembly comprises an upper rotating shaft 6, an upper channel steel 7, a lower rotating shaft 8 and a lower channel steel 11;
go up the bottom of channel-section steel 7 welding at one-level chute 4, go up 6 horizontal installation of pivot and can follow the axis rotation of last pivot 6 in last channel-section steel 7, the one end vertical welding of pivot 8 is on last pivot 6 down, and the elliptical aperture of the other end extension going up 7 bottoms of channel-section steel is connected with lower channel-section steel 11, and gasket 10 and nut 9 are installed to the tip that lower pivot 8 and lower channel-section steel 11 are connected, open at the both ends of channel-section steel 11 down has second grade chute connecting hole 12.
The utility model discloses utilize shaped steel as one-level chute 4, light-duty timber structure as second grade chute 5. The two-stage chute is connected through the rotating shaft component. Because second grade chute 5 adopts the wooden structure of lightweight, the manual work can be rotatory, and the convenience is better, and the work efficiency is higher.
When the chute is used, the first-stage chute 4 is lifted by the crawler crane 1 and is matched with the concrete transport vehicle 2 to transport concrete, the top end of the first-stage chute 4 is connected with the enclosure structure steel sheet pile 3 through a clamping ring to form hinged connection, and the first-stage chute 4 can be ensured to rotate up and down under the condition of ensuring safety and stability; the upper end of the second-stage chute 5 is connected with the lower end of the first-stage chute 4 through a rotating shaft assembly, and the second-stage chute 5 can rotate 360 degrees in the horizontal plane. The first-stage chute 4 is adjustable up and down, the second-stage chute 5 is adjustable in level, and the chute structure is graded and rotated, so that the coverage range of chute pouring is greatly enlarged.
The processing parameters of the chute need to be determined according to the width and the depth of the foundation pit, and the chute angle needs to be determined according to the slump, the workability and other performances of the concrete. The construction conditions and chute parameters which are successfully applied to the casting process of the concrete of the bottom plate of the river bottom of the Kanapu river under the project S1 segment EJD-6 in the great harbor of Bengal at present are as follows:
