Description
Technical Field
The utility model belongs to the technical field of the construction, especially, relate to a hammer and bury underground and protect a device.
Background
At present, the number of pile foundations used in various projects is dozens, and according to different construction processes, the current leading pile types in China are divided into a bored pile, a vibrating bored pile, a rammed pile, a manual hole digging pile, a prestressed pipe pile, various flexible semi-flexible piles (such as a cement mixing pile and a powder spraying pile, a high-pressure rotary spraying pile, a sand pile or a gravel pile) for soft foundation treatment and the like; when the construction of the bored pile is carried out in the area with the stone on the surface, the stone with higher hardness is often encountered, so that the steel casing is driven into the bored pile or the bored pile is difficult to form the hole. The soil body property of the mouth of the drilled pile is poor in a certain length range, so that a steel casing is required to be used for protecting the wall, and the hole wall is prevented from collapsing. The steel protects a section of thick bamboo and squeezes in-process and meet the stone, because stone intensity is higher, cause the steel to protect a section of thick bamboo and can't normally transfer to the design degree of depth, if insert by force and beat, often protect a section of thick bamboo end opening even the turn-up is serious also can't continue to squeeze in.
The common engineering measures for treating the sinking of the embedded pile casing mainly comprise the following measures:
the excavation method can directly excavate the stone and remove the exposed stone after the stone is excavated when the buried depth of the stone is shallow. However, when the buried depth of the stone block is large or underground water is abundant, the method needs to adopt a foundation pit support structure, and the economy is poor.
And in the blasting method, after the steel casing sinks and meets the stone, the soil in the steel casing is manually excavated until the stone is exposed, blasting holes are drilled on the stone, and the stone is blasted after explosive is filled. The method has the advantages that the medicine loading is difficult to control, the steel casing can deform when the medicine loading is too large, meanwhile, the disturbance on the peripheral soil body is too large, and the treatment efficiency is low when the medicine loading is too small. In addition, it is very difficult to drill blast holes in underwater construction or when underground water is abundant.
According to the hole sweeping method, after the steel casing sinks and meets the stone, the boulder is removed by the pore-forming drill, under the condition, the steel casing often impacts the bottom curling edge in the sinking process, and the drill bit of the pore-forming drill cannot drill out the lower bottom opening of the casing, so that the stone cannot be drilled and broken, and the drill bit of the drill is easy to wear. Even if the bottom of the steel pile casing is not curled and deformed, the steel pile casing is difficult to follow and sink due to incomplete treatment of stones caused by the gap between the steel pile casing and the pore-forming drilling machine.
In short, the above various embedded casings always have such or other problems in terms of casing quality, influence on surrounding environment and buildings, construction safety, construction cost and the like. In recent years, the full-casing rotary digging cast-in-place pile is promoted by introducing foreign technologies,
for a pile machine, the rotary drilling improves the efficiency, but has the defect that a drill bit is easy to drop when the rotary drilling is in high-density clay construction or the rotary drilling cannot be carried out when hard rocks are encountered; and the equipment is expensive, the construction cost is extremely high, and the comprehensive efficacy is not high.
In view of the above problems, it is necessary to improve them.
