Pipeline 35 is starched to be connected to.It is convenient to work when being constructed using twist bit, and twist bit water intaking soil grouting behind shaft or drift lining speed of application is fast.
Using compound strength stake all-in-one machine provided by the utility model construct when, it is preferable that the pile-sinking machine be static press device,
Hammering device or vibration hammer device.
In conclusion can be realized dry construction with Jing Xuanjiao mechanism using the high-pressure rotary-spray of the utility model, being stirred with diameter
It mixes, the concentricity of peripheral pile and rigid pile is effectively ensured, while it is uniform to can be realized Soil-cement, pile body soil around pile replacement rate
High effect.When being constructed using compound strength stake all-in-one machine provided by the utility model, outermost cement earth pile of constructing first, then
Its center is drilled using twist bit to stake bottom designed elevation, and soil of fetching water injects high-mark cement slurry, solidification intensifier simultaneously
Or fine aggregate, it is finally pressed into rigid pile again, due to the injection of slurry, the bond stress of rigid pile is significantly improved, no longer by cement
The constraint of native wall thickness, bearing capacity of single pile are significantly improved, and solve the technical problem of insertion rigid pile difficulty, substantially reduce
Requirement to construction site bearing capacity.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
