The device can effectively solve the problem of ramming the foundation of deep soft soil in the ultra-soft soil foundation, enlarges the depth range of dynamic compaction, has good compaction effect on the soil body in the process of ramming the foundation, reduces the deformation effect of the soil body, improves the strength of the soil body, and can obviously reduce the noise influence in the construction process.
Description
Technical Field
The invention relates to a deep ramming pipe, and belongs to the technical field of civil engineering.
Background
In recent years, domestic dynamic compaction technology is rapidly developed, the application range is wider, the dynamic compaction method is that a larger impact force is applied to a foundation by using tamping, under the action of the impact force, the bearing capacity of a soil body is greatly improved, and the compressibility is also reduced. So far, the dynamic compaction method has been successfully and widely used for treating various types of gravel soil, sandy soil, artificial filling soil, general cohesive soil and the like, and particularly can treat large blocks of gravel soil which is difficult to reinforce by a general method and miscellaneous filling soil consisting of building, household garbage or industrial waste. However, the action reference surface of the dynamic compaction method is generally on the ground surface, and the processing depth is limited; meanwhile, the common dynamic compaction method is generally intermittent compaction and has high construction noise.
Disclosure of Invention
The invention aims to solve the technical problem of providing a deep ramming pipe for reinforcing soil bodies at different depths and a construction method thereof.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
the deep ramming pipe comprises a protective sleeve and a plurality of sections of ramming pipes, wherein the upper end of the protective sleeve is provided with a first connecting device connected with a hydraulic machine, the lower end of the protective sleeve is connected with a valve pile shoe, the ramming pipes can be arranged in the protective sleeve, the upper end of the ramming pipes is provided with a second connecting device connected with a vibrating head, and a third connecting device used for ramming pipe combination is further arranged between the ramming pipes.
Furthermore, the first connecting device adopts a flange connecting device or a buckle connecting device.
Furthermore, the second connecting device and the third connecting device both adopt flange connecting devices.
Furthermore, the outer diameter of the protective sleeve is 0.4-1.2 m.
Further, the length of the tamping pipe is 2-3 m.
Further, the bottom surface of the tamping pipe is a spherical surface.
The construction method adopting the deep rammed pipe comprises the following steps:
firstly, determining the position of a pile body according to a design site;
secondly, arranging a pipe well in the area needing to be reinforced for precipitation;
thirdly, driving the protective sleeve and the built-in tamping pipe into a preset foundation depth by using a hydraulic machine, separating the hydraulic machine from the protective sleeve, starting a hydraulic vibration head to enable the tamping pipe to penetrate through a valve pile shoe, and carrying out first-stage deep tamping on a soil body;
and fourthly, withdrawing the tamping pipe, connecting the protective sleeve with the hydraulic machine, pulling the protective sleeve up to a second-stage tamping position, filling the protective sleeve according to needs, starting the hydraulic vibration head again to tamp the tamping pipe to squeeze the filling into the soil body, and tamping the filling step by step from deep to shallow.
The invention achieves the following beneficial effects:
1. the tamping foundation problem of deep soft soil in the ultra-soft soil foundation can be solved by adopting a mode of freely combining a plurality of sections of tamping pipes, and the depth range of dynamic compaction is enlarged.
2. By adopting the device for construction, the construction process has good compaction effect on the surrounding soil body, reduces the deformation effect of the soil body, improves the strength of the soil body, and obviously reduces the noise influence in the construction process.
3. The device has the advantages of simple structure, strong practicability, wide application range and better future prospect.

As shown in fig. 1, a deep ramming pipe, including the protective sleeve 1 that is located the outside and a plurality of sections be located can be built-in the inside ramming pipe 2 that can make up freely of protective sleeve 1, protective sleeve 1 upper end periphery bilateral symmetry is equipped with the square hole 3 that is used for with the hydraulic press joint, and valve pile shoe 4 is connected to the lower extreme, and specific size material can refer to as follows: the outer diameter of the steel protective sleeve 1 is 0.4-1.2 m, the height of the upper square hole 3 is 8-10 cm, and the projection width is 12-15 cm. By adopting the mode, the quick connection with the hydraulic machine can be realized, and the operation efficiency is effectively improved. Ramming every festival length setting of pipe and at 2 ~ 3m, it can carry out the flange joint spare of independent assortment still to be equipped with between the pipe to ram for ramming the pipe and can making up according to the degree of depth requirement, it still is used for being connected with the vibrating head to ram the pipe upper end, adopt flange joint equally, can be with its and the unified adaptation of the flange joint spare between the pipe, guarantee to ram the commonality of pipe 2, above-mentioned connected mode can also adopt other connected modes, it can set up to plane or sphere to ram the bottom surface of the pipe, it is seamless connection to ram the contact surface between the pipe.
The construction method of the device comprises the following steps:
firstly, determining the position of a pile body according to a design site, and organizing construction materials, machinery and personnel in place;
secondly, arranging a pipe well in the area needing to be reinforced for precipitation;
thirdly, driving the protective sleeve 1 and the built-in tamping pipe 2 into a preset foundation depth by using a hydraulic machine, separating the hydraulic machine from a square hole 3 at the upper end of the protective sleeve, starting a hydraulic vibration head 5 to enable the tamping pipe 2 to penetrate through a valve pile shoe 4, and performing first-stage deep tamping on a soil body as shown in figure 2;
and step four, withdrawing the tamping pipe 2, pulling up the protective sleeve 1 to a second-stage tamping position through the square hole, filling materials into the protective sleeve according to needs, starting the hydraulic tamping pipe 2 again to squeeze and tamp the fillers to the soil body, and gradually tamping the fillers from deep to shallow step by step, wherein the step-by-step squeezing and tamping can play a role in squeezing and tamping the soil body to reduce deformation.
