Description

Technical Field

[0001] The utility model belongs to the field of aqueduct construction, and in particular relates to an in-situ cast-in-place trough making machine for a U-shaped thin-wall aqueduct body. Background Art

[0002] Aqueducts are overhead channels that carry water across rivers, valleys, depressions and roads. They are commonly used for irrigation and water delivery, as well as for flood and sand drainage. Large aqueducts can also be navigable. Aqueducts are mainly built with materials such as stone masonry, concrete and reinforced concrete.

[0003] At present, the channel making machine used in some large aqueducts has a construction span of more than 30 meters, a deadweight of more than 1,000 tons, and a total power of 166KW. This large channel making machine is suitable for the construction of large aqueducts with high overhead, large flow, large load and large span.

[0004] For small aqueducts used for irrigation and water delivery, these large channel making machines may not be suitable. Small aqueducts are usually small in scale and require less size and complexity of construction equipment. Using large channel making machines to build small aqueducts may waste resources and increase costs, or the equipment may be too large to be suitable for the construction environment of small aqueducts.

[0005] Therefore, small aqueducts still use the traditional formwork construction method during construction, first the base is constructed, then the formwork is constructed above the base, and after the formwork is installed, concrete is poured. In this construction method, the internal and external formwork are often installed or disassembled one by one, the construction speed is slow, and the formwork is repeatedly disassembled and installed, resulting in large losses. Utility Model Content

[0006] Aiming at the problems that during the construction of small aqueducts, the inner and outer templates need to be installed or disassembled one by one, the construction speed is slow, and the templates are repeatedly disassembled and installed, resulting in large losses, the utility model provides an in-situ cast-in-place trough making machine for a U-shaped thin-walled aqueduct body.

[0007] The utility model solves the technical problem by adopting a solution: a U-shaped thin-wall aqueduct body in-situ cast-in-place trough making machine, comprising a base, a U-shaped inner mold, an inner mold sliding unit and two sets of outer molds.

[0008] The U-shaped inner mold is located above the base, and N groups of inner mold brackets and N support beams are installed therein, and the support beams are located above the inner mold brackets;

[0011] At least one slide rail is fixedly mounted on the top of the two sets of support seats, and the track wheels are mounted on the bottom of the support beam and can slide along the slide rail;

[0012] The two sets of outer molds are respectively located on the left and right sides of the U-shaped inner mold. The bottom end of the outer mold is detachably connected to the base. N sets of outer mold brackets are installed on the side away from the U-shaped inner mold, and the bottom of the outer mold bracket is in contact with the base.

[0013] Preferably, the height adjustment component is a hydraulic cylinder installed between the support seat and the base.

[0028] The U-shaped inner mold 31 is located above the base 1, and is installed with N groups of inner mold brackets 32 and N support beams 33. The support beams 33 are located above the inner mold brackets 32. By arranging the inner mold brackets 32 and the support beams 33, the structural strength of the U-shaped inner mold 31 is improved, deformation of the U-shaped inner mold 31 during use is avoided, and the durability of the U-shaped inner mold 31 is improved.

[0029] The inner mold sliding unit includes a track wheel 34 , two groups of support seats 22 and two groups of height adjustment components. The height adjustment components are hydraulic cylinders 21 . The two groups of hydraulic cylinders 21 are respectively located at the front and rear sides of the U-shaped inner mold 31 .

[0030] The top end of the hydraulic cylinder 21 is installed on the support seat 22 , and the height of the support seat 22 can be adjusted by controlling the extension and retraction of the hydraulic cylinder 21 .

[0031] At least one slide rail 23 is fixedly installed on the top of the two groups of support seats 22. In this embodiment, there are two slide rails 23. The track wheel 34 is installed at the bottom of the support beam 33 and can slide along the slide rail 23.
