Abstract
The utility model relates to a foundation pile that no -dig tunnel section was used need face diversified geology situation when tunnel engineering builds, because field space's restriction when the section of digging secretly meets the not good condition of geology situation, and the unable large construction machine that uses, conventional foundation pile can only adopt because length is too long also unable uses the utility model provides a foundation pile of piggy -back connector, the geological survey need the elder generation be carried out to specific foundation treatment method, according to the required data of geology surveying calculation, in position, diameter and length and the distance between adjacent of confirming the stake through data analysis, punches after that and puts the stake, and whether the back of one -tenth stake is at last detected qualified, and this kind of processing method effect is obvious, and the processing method is simple, and how a lot of people goes on simultaneously, does not need large -scale machinery, is fit for using in the less location in space.
Description
Technical field
The utility model is to be related to civil engineering field, and the foundation pile that specifically a kind of tunnel excavation section uses and tunnel are dark
Dig a section method for processing foundation.
Background technology
For bored tunnel, inevitably locally pass through the poor stratum of soil condition, in this location soil property not
When meeting intensity requirement, need this location carried out basement process, and the construction that the tunneling section in tunnel is carried out with basement process is empty
Between limited, main equipment cannot be laid, and during tunnel excavation, difficulty of construction is big, the duration is tight, therefore for tunnel excavation
For the basement process of section, need to find out that a kind of construction space is little, conveniently method.
Content of the invention
The technical problems to be solved in the utility model is the foundation pile providing a kind of tunnel excavation section to use, and can make tunnel
The tunneling section engineering time is shorter, in hgher efficiency, simpler, can improve soil bearing capacity simultaneously, strengthens the whole of tunnel structure
Body stability, reduces sedimentation.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is：
The foundation pile that a kind of tunnel excavation section uses, is characterized in that：Foundation pile is joined by some concrete prefabricated element head and the tail
Close and connect composition, described concrete prefabricated element is hollow structure, and has tail end groove in tail end, and top is provided with and tail end
Groove joins that suitable top is raised, and described foundation pile top is raised to be can be inserted in adjacent foundation pile tail end groove, described coagulation
Native prefabricated components surface is provided with some cement mortar connecting holes.
Described tail end groove lateral surface is concordant with pile body lateral surface, and flute wall thickness is the 1/2 of pile body thickness.
Described top projection medial surface is concordant with pile body medial surface, and flute wall thickness is the 1/2 of pile body thickness.
Described cement mortar connecting hole is the through hole connecting inside and outside stake.
Various geological conditions can be run into when tunnel excavation section is constructed, the poor situation of geological condition also often goes out
Existing, because positioned at tunnel excavation section, construction site is less, and there is height limitation, the foundation pile that normal conditions use cannot make
With can preferably solve these problems using foundation pile of the present utility model and its processing method, this kind of foundation pile is different from general
Logical prefabricated pile, need to first punch, then by concrete prefabricated element one section one section couple together, will connect during connecting
Pile body is put in stake holes, and this kind of mode can solve the problem that place is little, the problem highly being limited.
Foamed resin need to be smeared in the junction of adjacent concrete prefabricated element during connecting, the bubble after smearing
Foam resin can allow pile body more integrated, and the cushioning effect of foamed resin can improve the security of pile body simultaneously.
High-pressure injected water mud is wanted, this kind of high pressure method for implanting is that building industry is commonly used after pile body is put in stake holes
Injection mode, but need inlet to put into stake holes bottom during injection cement mortar, the carrying out with injection gradually will move on inlet,
This kind injection from bottom to top can reduce the bubble in cement mortar after injection, improves pile quality.

Specific embodiment
Below in conjunction with Figure of description and concrete preferred embodiment, the utility model is further described.
The foundation pile that a kind of tunnel excavation section uses, is characterized in that：Foundation pile 1 is by some concrete prefabricated element 3 head and the tail
Be connected composition, and described concrete prefabricated element 3 is hollow structure, and has tail end groove 5 in tail end, top be provided with
Tail end groove joins suitable top projection 4, and described foundation pile top raised 4 can be inserted in adjacent foundation pile tail end groove 5, described
Concrete prefabricated element 3 surface be provided with some cement mortar connecting holes 6.
In the present embodiment, tail end groove 5 lateral surface is concordant with pile body lateral surface, and flute wall thickness is the 1/2 of pile body thickness.
In the present embodiment, top projection 4 medial surfaces are concordant with pile body medial surface, and flute wall thickness is the 1/2 of pile body thickness.
In the present embodiment, cement mortar connecting hole 6 is the through hole connecting inside and outside stake.
Various geological conditions can be run into when tunnel excavation section is constructed, the poor situation of geological condition also often goes out
Existing, because positioned at tunnel excavation section, construction site is less, and there is height limitation, the foundation pile that normal conditions use cannot make
With can preferably solve these problems using foundation pile of the present utility model and its processing method, this kind of foundation pile is different from general
Logical prefabricated pile, needs subdrilling stake holes 2, then by concrete prefabricated element 3 one sections one section couple together, connect during will connect
Good pile body 1 is put in stake holes 2, and this kind of mode can solve the problem that place is little, the problem highly being limited.
Foamed resin need to be smeared in the junction of adjacent concrete prefabricated element 3 during connecting, after smearing
Foamed resin can allow pile body 1 more integrated, and the cushioning effect of foamed resin can improve the security of pile body 1 simultaneously.
High-pressure injected water mud is wanted, this kind of high pressure method for implanting is that building industry is commonly used after pile body is put in stake holes 2
Injection mode, but injection cement mortar when need inlet to put into stake holes bottom, with injection carrying out gradually by inlet
Move, this kind injection from bottom to top can reduce the bubble in cement mortar after injection, improve pile quality.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model is not limited merely to above-mentioned
Embodiment, all technical schemes belonging under the utility model thinking belong to protection domain of the present utility model.It should be pointed out that it is right
For those skilled in the art, some improvements and modifications under the premise of without departing from the utility model principle,
Should be regarded as the protection domain of utility model.
