A biggish impact force, under impact force action, the bearing capacity of the soil body is greatly improved, and compressibility also decreases.To being at present
Only, heavy-tamping method has succeeded and has been widely used for handling all kinds of gravelly soils, sandy soil, artificial earth fill and general clay etc., special
It is not miscellaneous the filling out that can be handled conventional method and be difficult to the bulk rubble class soil reinforced and building, house refuse or industrial waste composition
Soil.But the effect datum level of heavy-tamping method handles depth and is restricted generally in earth's surface;Common heavy-tamping method is usually to be interrupted simultaneously
Formula is rammed, and construction noise is big.
Summary of the invention
It rams and manages the technical problem to be solved by the invention is to provide a kind of deep layer that the corresponding different depth soil body is reinforced
And its construction method.
In order to solve the above technical problems, the technical solution adopted by the present invention are as follows:
A kind of deep layer rammer pipe, including protection sleeve pipe and several sections ram pipe, and the protection sleeve pipe upper end is provided with and hydraulic press
The attachment device one of connection, lower end connect flap valve shoe, and the rammer pipe can be placed in the protection sleeve pipe, and upper end is provided with and shakes
The attachment device two of dynamic head connection, it is described to ram the attachment device three being additionally provided between pipe for ramming pipe combination.
Further, the attachment device one uses flange connecting apparatus or buckle connecting device.
Further, the attachment device two and the attachment device three are all made of flange connecting apparatus.
Further, the protection sleeve pipe outer diameter is 0.4~1.2m.
Further, the rammer length of tube is 2~3m.
Further, the rammer tube bottom face is spherical surface.
The construction method of pipe is rammed using above-mentioned deep layer, comprising the following steps:
Step 1: according to design on-site measurement pile body position;
Step 2: carrying out precipitation in the region arrangement pipe well that need to be reinforced;
Step 3: the protection sleeve pipe and its built-in rammer pipe are squeezed into scheduled ground depth with hydraulic press, it will
Hydraulic press and the protection sleeve pipe are detached from, and starting hydraulic vibration head makes to ram pipe across flap valve shoe, and it is deep to carry out the first order to the soil body
Layer is rammed;
Step 4: withdrawing the rammer pipe, the protection sleeve pipe and hydraulic press are connected, will be pulled out in the protection sleeve pipe to second
Grade rams position, carries out filler into protection sleeve as needed, is again started up hydraulic vibration head and rams the rammer pipe for filler
It is rammed to the soil body is compacted, tamps completion step by step by being deep to shallow filler step by step.
Advantageous effects of the invention:
1. being able to solve the rammer base problem of super soft ground mid-deep strata weak soil in such a way that more piece rams pipe independent assortment, expand
The big depth bounds of strong rammer.
2. being constructed using the present apparatus, work progress plays good compacted effect to the soil body of surrounding, reduces soil
Body metamorphosis improves soil strength, and significantly reduces the influence of noise in work progress.
3. present apparatus of simple structure and strong practicability, applied widely, future prospect is preferable.
Detailed description of the invention
Fig. 1 is example structure schematic diagram;
Fig. 2 is embodiment construction schematic diagram.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, a kind of deep layer rams pipe, protected including being located at external protection sleeve pipe 1 and several sections in built-in
The rammer pipe 2 that can be freely combined inside protecting pipe 1, protection sleeve pipe 1 upper periphery two sides are symmetrically arranged with for being clamped with hydraulic press
Square hole 3, lower end connect flap valve shoe 4, and specific size material can refer to as follows: 1 outer diameter of steel protection sleeve pipe is 0.4~1.2m,
Square hole 3 height in upper end is 8~10cm, 12~15cm of projection width.It may be implemented in this way quick with hydraulic press
Connection, effectively improves operating efficiency.It rams and manages the setting of every section length in 2~3m, ram and be additionally provided with and can be freely combined between pipe
Flange connector is combined rammer pipe according to depth requirements, rams pipe upper end and is also used to connect with vibration head, equally adopts
With flanged joint, it can be adapted to the flange connector rammed between pipe unification, guarantee the versatility for ramming pipe 2, above-mentioned connection side
Formula can also use other connection types, and ramming tube bottom face may be configured as plane or spherical surface, and ramming contact surface between pipe is seamless connection.
The construction method of above-mentioned apparatus is as follows:
Step 1: organizing construction's material, machinery, personnel are in place according to design on-site measurement pile body position;
Step 2: carrying out precipitation in the region arrangement pipe well that need to be reinforced;
Step 3: sleeve 1 and its built-in rammer pipe 2 will be protected to squeeze into scheduled ground depth with hydraulic press, by hydraulic press
It is detached from the square hole 3 of protection sleeve upper end, starting hydraulic vibration head 5 makes to ram pipe 2 across flap valve shoe 4, as shown in Fig. 2, right
The soil body carries out first order deep layer and rams;
Pipe 2 is rammed Step 4: withdrawing, connects to pull out to the second level on protection sleeve 1 by square hole and rams position, as needed
Carry out filler into protection sleeve, be again started up hydraulic rammer pipe 2 and ram filler to the soil body is compacted, by be deep to shallow filler step by step by
Grade compacting is completed, and compacted ram of filler can play the role of solid soil, Reducing distortion step by step.
