Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a combined casting steel plate sliding form for coal mine coal bunker construction with a lifting mechanism. Background Technique

[0002] In the field of coal bunker construction, the casting concrete steel plate sliding form technology has been applied to a certain extent. In the prior art, a relatively traditional formwork support system is usually adopted, such as wooden formwork or combined steel formwork. The current situation of existing products is that although the cost of wooden formwork is relatively low, the number of repeated uses is limited, and the strength and stability are insufficient; the combined steel formwork improves the strength and reusability to a certain extent, but the installation and disassembly processes are relatively cumbersome, and it is difficult to ensure the construction accuracy.

[0003] In terms of development, with the continuous progress of building construction technology, the overall one-time casting steel plate sliding form technology has gradually emerged. Its technological steps generally include drill and blast excavation, steel bar binding, installation and fixation of steel plates, concrete pouring, and lifting of the sliding form, etc.

[0004] In terms of technological conditions, it is necessary to ensure the flatness and perpendicularity of the construction site to ensure the smooth installation and use of the steel plate sliding form. At the same time, the mix ratio of concrete, pouring speed, vibration degree, etc. will also have an important impact on the construction quality.

[0005] However, there are some problems and disadvantages in the prior art. First of all, the construction efficiency of the traditional formwork support system is relatively low, affecting the project progress. This is because the installation and disassembly processes of the formwork are time-consuming and laborious, and a large amount of manual operation is required. Secondly, it is difficult to ensure the construction accuracy, and deviations are likely to occur, affecting the structural stability and sealing performance of the coal bunker. The reason is that the splicing and fixation of the formwork are not firm enough, and human errors occur during the construction process. Moreover, for the coal bunker structure with complex shapes, the adaptability of the prior art is poor, and it is difficult to meet the diverse design requirements. This is because the shape and size of the formwork are relatively fixed and lack flexibility.

[0006] To sum up, there are problems such as low construction efficiency, difficult accuracy guarantee, and poor adaptability in the prior art during the process of casting concrete in coal bunker construction, which urgently need to be improved and innovated.

[0007] Now, a new combined casting steel plate sliding form for coal mine coal bunker construction with a lifting mechanism is proposed to solve the above deficiencies. Content of the Utility Model
