Abstract
The prefabricated pier foundation construction of a kind of driving into type provided by the invention, report and design document supporting course and the requirement of pier body size are surveyed in base area, in factory or building site concrete knoll body.Unwrapping wire is carried out again to layout, and determines pier position.Prefabricated pier body is finally squeezed into by ground and supporting course using hammering method or slotting method of shaking.The prefabricated pier foundation construction of a kind of driving into type disclosed by the invention, substitute manually digging hole Cast-in-place concrete pier construction technology, greatly save labour, reduce labor intensity, save labour cost, reduce construction costs, and safely.
Description
Technical field
The invention belongs to technical field of building construction, and in particular to a kind of prefabricated pier foundation construction of driving into type.
Background technology
In architectural engineering foundation basic construction, common pier foundation construction technology is to take manually digging hole to supporting course
In ground, field mixing concrete is reproduced, pours to smash and forms.Due to the general pier length≤6m of pier foundation.Supporting course can be more close
Real silty clay, middle sand, gravelly sand soil, gravelly soil and harder rock soil etc..So artificial shoveling difficulty is larger, labour is big,
Speed of application is slow, labour cost is high.Particularly underground water is relatively abundant, situations such as weak intercalated layer be present, it occur frequently that construction quality
And security incident.
The content of the invention
The present invention is solves existing pier foundation construction, and difficulty is larger, labour is big, speed of application is slow, labour cost is high
Almost problem, there is provided one kind can save labour, reduce labor intensity, save labour cost and construction costs, the duration is fast,
The prefabricated pier foundation construction of driving into type of safety.
In order to solve the technical problem of the present invention, the present invention is achieved by the following technical solutions：A kind of driving into type is pre-
Pier foundation construction processed, comprises the following steps：
Step 1：Levelling of the land：By design requirement absolute altitude, excavation and filling and the smooth location earthwork；
Step 2：Unwrapping wire is layouted：By design requirement, line setting, the position of pier base is determined；
Step 3：Make pier body：By the pier length of design requirement and pier footpath, in existing mill or prefabrication pier body；
Step 4：Using hammering method or slotting method of shaking, pier position is lifted to by loop wheel machine, then hammered to supporting course, prefabricated pier is squeezed into
Design requirement is held into layer；On the one hand its frictional force is increased, it is on the one hand low compared with conventional method expense, the time is short, good into pier quality.
Step 5：Pier to supporting course can not be reached individually, constructed using drawing bore method or excavating load；
Step 6：Blow counts and pier body embedded depth are recorded, completes prefabricated pier foundation construction.
Preferably, the section of the prefabricated pier is circular or square.
Preferably, the making material of the prefabricated pier is concrete, regeneration concrete or the shaped steel of different labels.
Compared with prior art, the beneficial effect that obtains of the present invention is：
The prefabricated pier foundation construction of a kind of driving into type disclosed by the invention, using prefabricated pier construction technology, substitute manually digging hole
Cast-in-place concrete pier construction technology, greatlys save labour, reduces labor intensity, saves labour cost, reduces construction costs.
The prefabricated pier foundation construction of a kind of driving into type disclosed by the invention, is fabricated into from prefabricated pier and squeezes into supporting course, entirely
Process mechanism degree is high, and quality control is strict, horizontal so as to which construction quality and safety in production be greatly improved.
The prefabricated pier foundation construction of a kind of driving into type disclosed by the invention, increases pier side friction, improves pier base
The bearing capacity of plinth, nothing left soil, without harmful substances such as waste water, poison gases.Site operation civilization, cleaning, meet environmental protection and save green
Color construction requirement.
Brief description of the drawings
Fig. 1 is the prefabricated pier foundation construction schematic diagram of driving into type.
Reference：1st, prefabricated pier；2nd, tamping machine is hammered into shape；3rd, supporting course.
Embodiment
Below in conjunction with the accompanying drawings, embodiment is described in detail.（Incorporated by reference to accompanying drawing, it is described in detail）
Referring to accompanying drawing 1, a kind of prefabricated pier foundation construction of driving into type, comprise the following steps：
Step 1：Levelling of the land：By design requirement absolute altitude, excavation and filling and the smooth location earthwork；
Step 2：Unwrapping wire is layouted：By design requirement, line setting, the position of pier base is determined；
Step 3：Make pier body：By the pier length of design requirement and pier footpath, at the scene or prefabrication pier body；
Step 4：Using hammering method or slotting method of shaking, pier position is lifted to by loop wheel machine, will be pre- with the hammering of tamping machine hammer 2 to supporting course 3
Pier 1 processed squeezes into the holding into layer of design requirement；On the one hand increase its frictional force, it is on the one hand low compared with conventional method expense, the time is short, into
Pier quality is good.Conventional method is using cast-in-place perfusion, it is necessary to which substantial amounts of human and material resources, costly.
Step 5：Pier to supporting course can not be reached individually, constructed using drawing bore method or excavating load；
Step 6：Blow counts and pier body embedded depth are recorded, completes prefabricated pier foundation construction.
Further, the section of the prefabricated pier is circular or square.
Further, the making material of the prefabricated pier is concrete, regeneration concrete or the shaped steel of different labels.
A kind of prefabricated pier foundation construction of driving into type, using prefabricated pier construction technology, substitute manually digging hole Cast-in-place concrete pier
Construction technology, labour is greatlyd save, reduce labor intensity, save labour cost, reduce construction costs.Made from prefabricated pier
To supporting course is squeezed into, overall process mechanization degree is high, and quality control is strict, raw so as to which construction quality and safety be greatly improved
Production is horizontal.
Listed above is only one of specific embodiment of the present invention.It is clear that the invention is not restricted to above example, may be used also
To there is many similar reshapings.What one of ordinary skill in the art directly can export or associate from present disclosure
All deformations, are considered as invention which is intended to be protected.
