Abstract
The present invention relates to technical field of building construction more particularly to a kind of foundation pile pile making methods, comprising the following steps: one, using drilling machine bore the hole that diameter is greater than 0.3 meter on ground；Step 2: injecting cement slurry in hole；Three, before cement slurry is not dry, it is put into threaded rod in hole, has screw thread, the top welded connections of threaded rod around threaded rod；Four, threaded rod is set in cement slurry i.e. basis of formation.Neighboring buildings are not influenced using this method, are not take up the space of surrounding buildings, can be constructed in minimum space, large scale equipment, the construction of the small space especially suitable for old residential area are not used.
Description
Technical field
The present invention relates to technical field of building construction more particularly to a kind of foundation pile pile making methods.
Background technique
Currently, in the transformation process in old city, for example, installing elevator additional in old residential area, it is necessary to elevator
Install basis, currently used mode or traditional piling mode additional, i.e., first ground makes a call to a depth and stirs stake, then takes advantage of stake and do not do feelings
Be put into a cement pole under condition, the shortcomings that such structure is: will use large scale equipment, ambient enviroment is required it is relatively high, for
The construction of old residential area at present is simultaneously not suitable with.If this mode is more infeasible by the way of drilling again descending reinforcing cage, drilling
It can not drill, underground water can make to collapse around hole, need to do the sealing of surrounding, and project amount is very big, and cost is also especially high.
Thus, it would be highly desirable to research and develop a kind of convenient, the especially small foundation pile pile making method of occupied space of construction.
Summary of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, and provide a kind of foundation pile pile making method.
The present invention to achieve the above object, using following technical scheme: a kind of foundation pile pile making method, it is characterised in that:
The following steps are included:
Step 1: boring the hole that a diameter is greater than 0.3 meter on ground using drilling machine；
Step 2: injecting cement slurry in hole；
Step 3: being put into threaded rod in hole before cement slurry is not dry, having screw thread, threaded rod around threaded rod
Top welded connections；
Step 4: threaded rod is set in cement slurry i.e. basis of formation.
Preferably, in step 2, side drilling marginal not enters cement slurry.
Preferably, in step 2, the drilling rod of drilling machine is hollow structure, is equipped with leakage fluid dram, cement slurry in the front end of drilling rod
Enter out of drilling rod, is injected into hole from leakage fluid dram.
The beneficial effects of the present invention are: not influencing using this method on neighboring buildings, it is not take up the space of surrounding buildings,
It can construct in minimum space, it is only necessary to a drilling machine, small space especially suitable for old residential area
Construction.
Detailed description of the invention
Fig. 1 is working state figure of the invention；
Fig. 2 is the structural schematic diagram of drilling rod in the present invention；
Fig. 3 is the installation status diagram of threaded rod in the present invention.
Specific embodiment
With reference to the accompanying drawing and the preferred embodiment specific embodiment that the present invention will be described in detail.As shown in Figure 1-3,
A kind of foundation pile pile making method, comprising the following steps: be greater than Step 1: boring a diameter on ground using drilling machine
0.3 meter of hole；Drilling machine uses middle-size and small-size drilling machine, and overall volume is not especially big.The drilling rod of drilling machine is using currently used
Drilling rod 1, bottom have Counterboring apparatus, that is, rubber belt 2, and drilling rod lower part enters, Step 2: In with outlet for cement slurry
Cement slurry 3 is injected in hole, by the way of drilling marginal not enters cement slurry using side.Specifically, the drilling rod of drilling machine is hollow structure, boring
The lower part of bar is equipped with outlet 4, and cement slurry enters out of drilling rod top entrance 5, is injected into hole from leakage fluid dram.
Step 3: being put into threaded rod 6 in hole before cement slurry is not dry, having screw thread, threaded rod around threaded rod
Top welded connections；Connector is used to be attached with the equipment on top.
Step 4: threaded rod is set in cement slurry i.e. basis of formation.Cement slurry is complete with the threaded rod in hole after having done
Beauty combines, and side grinding resistance is very big, so this foundation pile can be very secured.
Neighboring buildings are not influenced using this method, are not take up the space of surrounding buildings, it can be in minimum space
Construction does not use large scale equipment, the construction of the small space especially suitable for old residential area.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
