Description

Technical Field

[0001] The utility model relates to the technical field of highway engineering, in particular to a pin-type formwork for preventing side collapse in pavement water-stable construction. Background Technique

[0002] The water-stable layer is the abbreviation of the cement stabilized crushed stone layer, that is, cement is used to consolidate the graded crushed stone and is completed through compaction and curing. During the construction of the pavement water-stable layer, it is necessary to install retaining side formworks on both sides of the roadbed first to support the materials during the laying process of the water-stable layer and prevent the materials at the edge of the water-stable layer from collapsing and flowing outwards to the roadbed.

[0003] After retrieval, the patent with the publication number CN219862250U discloses a pin-type formwork for preventing side collapse in pavement water-stable construction. By setting a positioning component, an ear hanger is fixedly installed in the groove on the inner wall of the formwork, and a pin is inserted into the pin hole inside the ear hanger, so as to conveniently and quickly fix and install the formwork on the ground through the pin, which is convenient and fast for the installation and fixation of the formwork.

[0004] In the actual use process of the above scheme, although it is convenient to quickly fix and install the formwork through the positioning component, the ear hanger of the positioning component protrudes from the back of the formwork and is fixedly welded to the formwork. Therefore, it will interfere with the stacking of the formwork during the transportation process of the formwork, and it is easy to occupy more storage space. At the same time, although this scheme is convenient to position and connect adjacent formworks through the cooperation of the pin and the sleeve, it cannot tighten two adjacent formworks together, and there is likely to be a large joint between the formworks, which is likely to cause leakage of the water-stable layer materials and needs to be improved.
