Description

Technical Field

[0001] The utility model relates to the technical field of frame column construction, in particular to a frame column template system and a frame column construction system. Background Art

[0002] Aqueduct, also known as water bridge, is an overhead water channel that connects the two ends of the aqueduct to the canal and transports the canal water across rivers, valleys, depressions and roads. It is commonly used for irrigation and water delivery, as well as flood and sand drainage. After a long period of use, large aqueducts will have uneven settlement and exposed steel bars. At this time, the aqueduct needs to be dismantled and rebuilt. However, aqueducts are often located in main canals. If they are not rebuilt during the non-irrigation period, it will have a great impact on the irrigation of farmland below the aqueduct.

[0003] The existing method for rebuilding aqueducts is generally cast-in-place. The cast-in-place construction method has the following disadvantages: (1) Long construction period. Since the cast-in-place aqueduct needs to be cast on site, the construction period is relatively long; (2) Construction environment restrictions: The construction of cast-in-place aqueducts is greatly affected by the on-site environment, such as weather conditions, which may affect the construction progress. Utility Model Content

[0011] Furthermore, the first template and the third template are both horizontal plates, and the second template is a vertical plate or an inclined plate.

[0012] Furthermore, the second template is an inclined plate; the supporting structure also includes a second cushion block, and the second cushion block is provided between the second template and the hardened supporting surface.

[0013] Furthermore, the cross-sectional shape of the first cushion block is square, and the cross-sectional shape of the second cushion block is triangle.
