[0002] Manually excavated cast-in-place piles refer to piles formed by manually excavating holes, placing reinforcing cages, and then pouring concrete. To prevent collapse during excavation, concrete retaining walls need to be poured around the hole, with each section of retaining wall poured manually as it is excavated downwards. A chute is required when pouring the retaining concrete. However, conventional chutes require multiple rotations during pouring to meet the requirements, making them cumbersome to use. Utility Model Content

Multiple slide rails are provided around the lower side of the cone cap. The top of the slide rails is hinged to the lower surface of the cone cap via a hinge. The main rod is fixedly connected to the center of the lower surface of the cone cap. The positioning sleeve and the connecting sleeve are sleeved on the outer side of the main rod. The connecting sleeve is located above the positioning sleeve. The slide rails and the connecting sleeve are movably connected through the secondary rod.

[0006] As a further description of the above technical solution:

[0007] The outer surface of the main rod is provided with an external thread near the bottom, and the inner wall of the positioning sleeve is provided with an internal thread. The positioning sleeve is threadedly connected to the outer surface of the main rod.

[0008] As a further description of the above technical solution:

[0009] The inner wall of the connecting sleeve is smooth.

[0010] As a further description of the above technical solution:

[0011] Both ends of the auxiliary rod are provided with hinge holes, and a first hinge plate with a hole is fixedly connected to the middle of the outer surface of the slide. One end of the auxiliary rod is movably connected to the first hinge plate with a hole through a pin.

[0012] As a further description of the above technical solution:

[0013] The outer surface of the connecting sleeve is fixedly connected with a plurality of second perforated hinge plates, and the other end of the auxiliary rod is movably connected to the second perforated hinge plates via a pin.

[0014] As a further description of the above technical solution:

[0015] The outer side of the chute is equipped with a protective wall and a template.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] This utility model has a simple structure, is easy to process, and can simultaneously pour a ring of concrete around the wall without multiple moves; at the same time, the size of the entire chute can be adjusted by adjusting the up and down position of the positioning sleeve, thus making it suitable for wall protection of different apertures.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3This utility model provides a technical solution: a special chute 7 for concrete pouring of manually excavated pile retaining wall 9, including a chute 7, the chute 7 being composed of a cone cap 1, a slide 2, a main rod 3, a secondary rod 4, a positioning sleeve 5 and a sleeve. Multiple slides 2 are provided around the lower side of the cone cap 1. The top of the slide 2 is hinged to the lower surface of the cone cap 1 by a hinge. The main rod 3 is fixedly connected to the center of the lower surface of the cone cap 1. The positioning sleeve 5 and the connecting sleeve 6 are sleeved on the outer side of the main rod 3. The connecting sleeve 6 is located on the upper side of the positioning sleeve 5. The outer surface of the main rod 3 is provided with external threads near the bottom. The inner wall of the positioning sleeve 5 is provided with internal threads. The positioning sleeve 5 is threaded to the outer surface of the main rod 3. The inner wall of the connecting sleeve 6 is smooth.

[0025] The slide 2 and the connecting sleeve 6 are movably connected by a secondary rod 4. Both ends of the secondary rod 4 are provided with hinge holes. A first hinge plate with a hole is fixedly connected to the middle of the outer surface of the slide 2. One end of the secondary rod 4 is movably connected to the first hinge plate with a hole through a pin. Multiple second hinge plates with holes are fixedly connected to the outer surface of the connecting sleeve 6. The other end of the secondary rod 4 is movably connected to the second hinge plates with holes through a pin.

[0026] The outer side of the chute 7 is provided with a protective wall 9 and a template 8.

[0027] Working principle: When in use, rotate the positioning sleeve 5 to adjust its height on the main rod 3. At this time, the connecting sleeve 6 moves up and down to adjust its height. The up and down movement of the connecting sleeve 6 drives the slide 2 to rotate through the auxiliary rod 4, adjusting the chute 7 to a suitable size. Then, the chute 7 is placed between the already poured retaining wall 9 of the bored pile and the formwork 8 where the concrete for the retaining wall 9 is to be poured. During pouring, the concrete falls from above the cone cap 1 and then flows evenly along the surrounding slide 2 into the surrounding formwork 8, completing the pouring.
