Description

Technical Field

[0001] The utility model relates to the technical field of catenary foundation construction, and more specifically, to an auxiliary mold for catenary foundation pit pouring construction. Background Technique

[0002] With the rapid development of railway construction, the main content of railway engineering construction has gradually changed from the construction of new railways to the renovation of existing railway lines. The node construction periods of different specialties in the railway renovation project are different, resulting in mutual influence on the project progress in the railway renovation construction between different specialties. Therefore, eliminating the mutual influence between different specialties has become the most important problem.

[0003] After retrieval, the utility model patent with the publication number of CN208884293U discloses an auxiliary mold for catenary foundation pit pouring construction, which includes two parallel long wooden squares. Four vertically placed rectangular plates are arranged between the long wooden squares. A plurality of fixing structures are arranged outside the rectangular plates. A steel mold plate is arranged above the rectangular plates. Short steel pipes for the anchor bolts to pass through are welded on the steel mold. Each fixing structure includes four steel pipe fasteners, two threaded steel bars and four long steel pipes. The four steel pipe fasteners are respectively located at the four corners of the rectangular cylinder surrounded by the rectangular plates. The two threaded steel bars are respectively arranged outside two opposite rectangular plates, and their two ends respectively pass through the internal threaded holes on a steel pipe fastener. The four long steel pipes are arranged in pairs outside the other pair of opposite rectangular plates, and their two ends are respectively clamped in the concave arc surfaces on the steel pipe fasteners. This patent can realize the catenary foundation pit pouring when the ground elevation of the subgrade without side filling is insufficient, and can be applied to the catenary construction field.

[0004] However, the above patent still has the following deficiencies: Two threaded steel bars and four long steel pipes in the fixing structure need to be connected by four steel pipe fasteners, which is rather cumbersome and lacks convenience during connection. Moreover, it is not convenient to adjust the height of the rectangular plates. When there are differences in the ground elevation of the subgrade without side filling, it is not convenient to adaptively adjust the different heights of the pouring molds. Therefore, we propose an auxiliary mold for catenary foundation pit pouring construction. Content of the Utility Model
