[0002] Since the excavation construction of stone roadbed for mountain highways faces the influence of various complex factors such as geological conditions and natural environment, the choice of construction plan will be directly related to the effectiveness of the project construction.

[0003] If ordinary blasting is used to excavate the stone roadbed, it is difficult to avoid the generation of shock waves, noise, dust and flying stones, which endanger the surrounding people and the environment. However, static excavation can not only ensure the safety requirements of the project, but also has a good environmental protection effect, and the construction is simple and the operation is safe.

[0004] The existing static crushing scheme is to drill holes on the stone roadbed and fill the holes with crushing agents. The static crushing of the stone roadbed is achieved through the expansion of the crushing agents. In order to ensure the crushing effect, a large amount of crushing agents need to be filled, and a sufficiently large drill hole is required. However, large-diameter drill holes are prone to blowout after filling and pouring crushing agents. Therefore, it is necessary to install blowout prevention equipment in large-diameter drill holes to avoid blowout and improve the static crushing effect. Utility Model Content
