Description

Technical Field

[0001] This utility model relates to the field of inland waterway lock construction technology, specifically to an auxiliary system for one-time forming of valve well slots in the working and maintenance system of a lock water conveyance system. Background Technology

[0002] In recent years, with the continuous development of inland waterway transportation, its position in the comprehensive transportation system has become increasingly prominent. As inland waterway projects flourish nationwide, locks, as a key infrastructure for inland waterway transportation, have also ushered in new development opportunities. Within the sub-sectors of inland waterway lock project construction, to ensure the accuracy of the gate slots and the installation of embedded parts, the gate slots of the working and maintenance valve wells in the water conveyance system are typically constructed in two phases.

[0003] With the continuous improvement of construction standards, the two-phase construction method, while a common approach, also has significant drawbacks: First, it has a long construction period. The second-phase concrete pouring can only be carried out after the first phase is completed and reaches a certain strength. For projects requiring rapid deployment, this method may extend the construction period and affect the overall project schedule. Second, it is more difficult to construct. The second-phase concrete pouring demands higher technical standards, especially in the doorway area. Due to the confined space, construction is challenging and prone to quality problems such as loose concrete and excessive air bubbles. These issues may affect the durability and stability of the doorway. Third, it requires more advanced technology for embedded parts. The installation accuracy is affected. During the second-phase concrete pouring process, it is necessary to install and fix embedded parts, such as guide rail foundation bolts. However, due to the deformation and vibration of the second-phase concrete pouring, the installation accuracy of the embedded parts may be affected, causing the embedded parts to shift or loosen. This may affect the subsequent installation and fixing of the gate slot guide rail, and thus affect the normal operation of the entire water conveyance system. Fourth, maintenance is difficult. Because the gate slot structure of the second-phase concrete pouring is complex and is usually located underwater or in a humid environment, maintenance is relatively difficult. Once problems occur, such as concrete spalling or cracks, it may take a lot of time and money to repair. Utility Model Content
