[0018] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer according to the following description. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0020] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a component centered. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] like Figure 1 to Figure 2As shown, a special hopper for pouring concrete for prefabricated T-beams in tunnels includes a hopper body 1, a movable discharge port 2 is installed at the bottom of the hopper body 1, four hopper columns 3 are evenly fixed on the circumference of the outer wall of the hopper body 1, and reinforcing square steels 4 are welded in sequence between the lower ends of the four columns 3. A counterweight assembly 5 is installed on the corresponding two reinforcing square steels 4 at the lower end of the inner wall of each column 3, a balance beam assembly 6 is welded in the hopper body 1, and hanging points 7 are welded on the four corners of the balance beam assembly 6.

[0024] The hopper body 1 is processed by using a 5mm thick steel plate, and the bottom of the hopper body 1 is a D50cm movable discharge port 2, and the thickness of the movable discharge port 2 is 5mm.

[0025] The hopper column 3 is made of 12cm×5cm×3mm square steel, and the bottom of the hopper column 3 is reinforced with four 8cm×4cm×3mm reinforcing square steels 4. Two 5cm×4cm×3mm square steels are used as the balance beam assembly 6 in the hopper body 1, and the hanging point 7 is set on the balance beam assembly 6 with Φ28 round steel.

[0026] Because the hopper body 1 is flat and heavy on the top and light on the bottom, five 30cm×30cm×2cm steel blocks are placed at the corners of the four hopper columns 3 at the bottom of the hopper body 1 as counterweight components 5.

[0027] The construction process is as follows:

[0028] 1. Hopper assembly:

[0029] Assemble the hopper in sequence according to the drawings, including: forming the hopper body 1 → installing the hopper column 3 → installing the reinforcing square steel 4 at the bottom of the hopper column 3 → installing the balance beam assembly 6 and hanging point 7 inside the hopper body 1 → installing the counterweight assembly 5 inside the hopper column 3. After each part is installed, weld supports to ensure the stability of the hopper.

[0030] 2. Lifting hopper to pour concrete:

[0031] Place the hopper on the ground, and the concrete tank truck unloads the concrete into the hopper body 1. Slowly lift the hopper using the gantry crane in the tunnel. Observe the balance of the hopper during the lifting process. When the hopper is directly above the precast beam to be poured, slowly open the hopper discharge port 2 and pour the concrete into the precast T-beam with the template supported.

[0032] The use of a special hopper for pouring concrete for precast T-beams in tunnels can effectively solve the problem of not being able to use conventional hoppers to pour precast T-beam concrete due to tunnel clearance restrictions. The hopper body 1 is provided with a balance beam assembly 6 and a counterweight assembly 5 at the bottom, which solves the problem of shaking and unstable center of gravity when the hopper is lifted to pour concrete.

[0033] The utility model is mainly used for concrete pouring of prefabricated T-beams in tunnels, which ensures the working safety of construction workers and improves the construction efficiency, and has high practicality and popularization and application value.

[0034] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
