Description

Technical Field

[0001] This utility model relates to the field of hydraulic aqueduct construction technology, and in particular to a U-shaped cast-in-place aqueduct construction system. Background Technology

[0002] The construction of the aqueduct body is a key sub-project. The construction methods include directly pouring concrete into the trough by setting up a jacking pump or using a crane to lift and transport the hopper for pouring. Both of these methods require more temporary site occupation and have higher requirements for the bearing capacity of the site's foundation, resulting in disadvantages such as high foundation treatment costs and poor economic efficiency.

[0003] A trenching machine and method disclosed in patent publication number CN115094836A are designed with a longitudinal beam and a hoisting mechanism that travels on the longitudinal beam. The hoisting mechanism lifts concrete into the outer formwork assembly for pouring. This design eliminates the need for cranes and overhead pumps, effectively solving the aforementioned problems. However, during concrete pouring, manual vibration is required to ensure the uniformity of the concrete, leading to high labor intensity and difficulty in guaranteeing uniform vibration, thus affecting the quality of the aqueduct formation. Utility Model Content

[0004] The purpose of this invention is to provide a U-shaped cast-in-place aqueduct construction system that improves the uniformity of concrete materials, thereby reducing labor intensity and increasing construction efficiency.

[0005] The technical solution of this utility model is: a U-shaped cast-in-place aqueduct construction system, including a main beam, a template system disposed on the main beam, and a vibrator. The template system includes an outer mold connected to the main beam and an inner mold spaced apart inside the outer mold, forming a forming cavity between the outer mold and the inner mold. At least one vibration hole is opened on the inner mold. The vibrator includes a drive motor and a rod body connected to the drive motor. The drive motor is placed in the inner mold, and the rod body extends into the forming cavity through the vibration hole.

[0006] In the above solution, this utility model improves the uniformity of concrete material, reduces the labor occupation rate, lowers labor intensity, and improves construction efficiency by adding a vibrating rod that can extend into the molding cavity and vibrates the concrete while it is being poured.

[0007] Preferably, the U-shaped cast-in-place aqueduct construction system further includes a vibrator disposed inside the outer mold and facing the forming cavity.

[0008] Preferably, multiple vibration holes are arranged along the length of the inner mold, and two vibration holes are symmetrically arranged on the same cross-section of the inner mold.

[0009] Preferably, the inner mold is also provided with an exhaust hole, which is located next to the vibrating hole.

[0010] Preferably, the inner mold has a U-shaped structure, and in the same U-shaped cross section, the vent hole is located at a lower position than the vibratory hole.

[0011] Preferably, the U-shaped cast-in-place aqueduct construction system further includes at least one gantry crane traveling on the main beam and a material loading area located beside the formwork system, wherein the gantry crane travels back and forth between the material loading area and the formwork system.

[0012] Preferably, the material loading area is equipped with a concrete transport vehicle, and the gantry crane is equipped with hoppers that are adapted to the concrete transport vehicle and the formwork system respectively.

[0013] Preferably, the upper end of the main beam is provided with a guide rail; the gantry crane includes a gantry frame, a traveling mechanism located at the lower end of the gantry frame and adapted to the guide rail, a winch movable on the gantry frame, and a remote control connected to the winch via a cable, wherein the end of the wire rope on the winch is provided with a hook.

[0014] Preferably, the U-shaped cast-in-place aqueduct construction system further includes at least one gantry crane traveling on the main beam and a pre-tying area located beside the formwork system, wherein the gantry crane travels back and forth between the pre-tying area and the formwork system.

[0015] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0016] I. This utility model improves the uniformity of concrete materials, reduces labor requirements, lowers labor intensity, and increases construction efficiency by adding a vibrating rod that can extend into the molding cavity and vibrates the concrete during pouring.

[0017] Second, by adding a vibrator, this utility model can eliminate tiny air bubbles on the concrete surface, making the concrete surface smoother and more even, and greatly improving the appearance quality of the concrete.

[0018] Third, this utility model has vent holes on the inner mold to facilitate the discharge of air from the molding cavity;

[0019] Fourth, this utility model sets up a gantry crane on the main beam to realize the material receiving and feeding of the hopper, which is not limited by the pouring height. When the pouring surface is high, it is not necessary to use a ground pump or add a large crane.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0027] like Figure 1 As shown, the U-shaped cast-in-place aqueduct construction system provided in this embodiment includes a main beam 1, a formwork system 2, a gantry crane 3, a hopper 10, a concrete transport vehicle 12, a vibrator 15, and a vibrator 16. The main beam 1 is arranged from left to right along its length X as a pre-tying area 20, a trenching area 19, and a material loading area 18.

[0028] like Figure 2 As shown, the main beam 1 has two triangular trusses 102 arranged in the width direction Y, and the bottoms of the two triangular trusses 102 are connected by a crossbeam 103. Each triangular truss 102 has a guide rail 101 at its upper end. The length of the guide rail 101 is slightly less than the length of the triangular truss 102 to provide sufficient travel for the gantry crane 3.

[0029] The template system 2 includes an outer mold 21 connected to the main beam 1 and an inner mold 22 spaced apart inside the outer mold 21. A forming cavity 23 is formed between the outer mold 21 and the inner mold 22, and the forming cavity 23 is used to pour concrete to form the aqueduct body 11. Figure 3 As shown, the lower end of the inner mold 22 has two vibration holes 13 and an exhaust hole 14 located between the two vibration holes 13. Multiple vibration holes 13 and exhaust holes 14 are spaced apart along the length of the inner mold 22. The inner mold 22 has a U-shaped structure, and within the same U-shaped cross-section, the exhaust hole 14 is positioned lower than the vibration holes 13. That is, a height H1 is formed between the exhaust hole 14 and the bottom surface of the forming cavity 23, and a height H2 is formed between the vibration holes 13 and the bottom surface of the forming cavity 23, where H2 > H1. When the concrete pouring surface has reached the first pouring height, the elevation can be controlled through the exhaust hole 14 to prevent concrete from overflowing from the vibration holes 13.

[0030] Both the vibrating rod 15 and the vibrator 16 are purchased components. The vibrating rod 15 is an insert type, and the vibrator 16 is an attached type. The vibrating rod 15 includes a drive motor 151 and a rod body 152 connected to the drive motor 151. The drive motor 151 is placed in the inner mold 22, and the rod body 152 extends into the forming cavity 23 through the vibration hole 13. The vibrating rod 15 is used to vibrate the concrete near the corners of the formwork and the embedded reinforcing cage. In addition, the insert type vibrating rod 13 can be inserted into the previous layer of poured but not yet solidified concrete to ensure the bonding surface between the old and new concrete. Because air bubbles are generated during the insertion of the vibrating rod 15, the vibrator 16 is used for secondary vibration to eliminate tiny air bubbles on the surface, making the concrete surface smoother and flatter. The vibrator 16 is located inside the outer mold 21 and faces the forming cavity 23.

[0031] like Figure 1 , Figure 2 As shown, there are two gantry cranes 3. One travels between the pre-stretching area 20 and the trenching area 19 to lift the steel cages in the pre-stretching area 20 to the formwork system 2. The other travels between the loading area 18 and the trenching area 19. A concrete transport vehicle 12 is provided in the loading area 18.

[0032] The gantry crane 3 includes a gantry frame 6, a traveling mechanism 5 located at the lower end of the gantry frame 6 and adapted to the guide rail 101, a winch 8 movably mounted on the gantry frame 6, and a remote control 17 connected to the winch 8 via a cable. A hook 9 is provided at the end of the wire rope on the winch 8. The hook 9 on the gantry crane 3, which travels back and forth between the loading area 18 and the troughing area 19, hooks a hopper 10. A lateral traveling system 7 is provided on the gantry frame 6, which drives the winch 8 to reciprocate in the width direction Y.

[0033] like Figure 4 As shown, the method for constructing an aqueduct using the aforementioned U-shaped cast-in-place aqueduct construction system includes the following steps:

[0034] S1, Start the traveling mechanism 5 and drive the gantry crane 3 to move to the loading area 18;

[0035] S2, driving concrete truck 12 to the working range of gantry crane 3 in loading area 18;

[0036] S3, start the lateral travel system 7 and winch 8, and lower the hopper 10 to the concrete transport truck 12 to receive the material;

[0037] S4, the molding cavity 23 adopts a layered and segmented casting method:

[0038] S4.1 Start the gantry crane 3 to lift the hopper 10 to the trenching area 19, and pour the concrete in the hopper 10 into the forming cavity 23 of the formwork system 2 through the transverse travel system 7;

[0039] S4.2, start the vibrator 15 and vibrator 16 to vibrate the concrete and exhaust air through the vent 14;

[0040] S4.3 After all the concrete in this section has been poured and vibrated, remove the rod 152 and seal the vibration hole 13.

[0041] S4.4, Repeat the above steps to complete the pouring of the next segment; finally, complete the pouring of all segments. When the concrete is poured in layers and segments to the top surface of the structure, repeat step S4.2.

[0042] S5. After the overall pouring is completed, the vibrator 16 is started again for secondary vibration to finally remove air bubbles from the aqueduct body 11. When using an immersion vibrator 15, air bubbles may be generated due to improper operation by workers. Secondary vibration by the attached vibrator 16 eliminates tiny air bubbles on the surface, making the concrete surface smoother and flatter.

[0043] This invention utilizes a gantry crane 10 mounted on the main beam 1 to deliver materials, eliminating limitations on pouring height. Furthermore, it eliminates the need for a ground pump or large cranes even when the pouring surface is high, resulting in low construction costs, a short construction period, and reduced land occupation by large equipment. The horizontal position and relative height of the hopper 10 are adjusted via remote control 17, improving pouring efficiency and accuracy, thereby enhancing construction quality.

[0044] This embodiment improves construction efficiency and reduces construction costs through the high-frequency vibration of the attached vibrator 16. Secondary vibration by the attached vibrator 16 eliminates tiny air bubbles on the concrete surface, making the concrete surface smoother and more even, thereby improving the appearance quality of the concrete.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
