Abstract
The method that pile for prestressed pipe stake core bore blocks when bearing platform construction is prevented the present invention relates to a kind of, comprising steps of one: determining the top section piling of every pile before prestressing pipe pile construction, and it is concentrated stacking by region；Two: production sealing steel plate；Three: carrying out stake core bore sealing with sealing steel plate in the top section piling one end determined, sealing steel plate and pile end plate are welded to connect using interruption, and sealing steel plate is placed by the lower part of pile end plate；Four: after bearing platform construction, welding position between sealing steel plate and pile end board being cut with hand-held cutting machine, sealing steel plate recycling is used as stake stem end plate.The present invention blocks stake core bore in pile foundation construction Shi Xianyong steel plate, prevents extruding of the mud in the natural reset of tempus intercalare and earth excavation from blocking stake core bore, to reduce the time spent when foundation platform construction because clearing up stake core bore, human and material resources.
Description
Technical field
The present invention relates to one kind to prevent obstruction method, specifically prevents pile for prestressed pipe stake core bore when bearing platform construction from blocking up
The method of plug.
Background technique
Tubular pole is usually to press friction pile design in the soft layer of coastal area, and when construction is mainly made with pile head elevation control
For final pressure or ceasing driving standard.It is extruded that soil layer resets naturally, the extruding of foundation pit or cushion cap earth excavation can allow after pile foundation construction
Stake in-core is crowded with soil, and foundation platform stake stem need to spend very big material resources, manpower to carry out the mud cleaning in stake core bore when constructing,
And it is not easy to clean out.
Summary of the invention
The present invention is directed to overcome the deficiencies of existing technologies, providing one kind prevents pile for prestressed pipe stake core bore when bearing platform construction from blocking up
The method of plug solves the problems, such as that pipe pile core bore is blocked by soil and influences the construction of stake stem in pile for prestressed pipe soft layer.
In order to solve the above-mentioned technical problem, the present invention is implemented as follows:
A method of prevent pile for prestressed pipe stake core bore when bearing platform construction from blocking, it is characterised in that include the following steps:
Step 1: the top section piling of every pile is determined before prestressing pipe pile construction, and it is concentrated by region and is stacked；
Step 2: production sealing steel plate, the sealing plate size is according to stake core bore dimensioned；
Step 3: stake core bore sealing is carried out with sealing steel plate in the top section piling one end determined, sealing steel plate is adopted with pile end plate
It is welded to connect with interruption, every section of fusion length is not less than 50mm, and the height of weld seam is broken when cannot exceed pile end plate to prevent pile follower
Bad hush panel, sealing steel plate are placed by the lower part of pile end plate；
Step 4: after bearing platform construction, cutting welding position between sealing steel plate and pile end board with hand-held cutting machine, sealing
Steel plate recycling is used as stake stem end plate.
Described prevents the method that pile for prestressed pipe sealing blocks when bearing platform construction, it is characterised in that: sealing steel plate setting
It goes wrong after the completion when sealing steel plate end bidding will to prevent hanging.
Described prevents the method that pile for prestressed pipe sealing blocks when bearing platform construction, it is characterised in that: pile top is using sealing
Pile top such as uses opening pile toe, and stake lower part also needs to be blocked.
The beneficial effects of the present invention are: being applicable in wide: coastal area tier building, low-rise building, industrial premises are mostly used tubular pole
As pile foundation, Design of Foundation stake top absolute altitude generally all on natural ground hereinafter, and coastal area soft layer it is more normal
See；It is good in economic efficiency: relative to the time, human and material resources required for cleaning stake core bore, carry out sealing in advance the required time,
Human and material resources are few very much, and hush panel remove after can the end plate of purposes stake stem use；Strong operability: required for this method
The goods and materials such as all machinery, equipment, material, personnel, be construction site it is existing or be easy to rent with and purchase.
Stake core bore is blocked in pile foundation construction Shi Xianyong steel plate, prevents mud in the natural reset and the earthwork of tempus intercalare
Extruding when excavation blocks stake core bore, to reduce the time spent when foundation platform construction because clearing up stake core bore, manpower, object
Power.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the structural schematic diagram of Fig. 1 overlook direction.
Specific embodiment
It is as shown in Figure 1, 2: a method of prevent pile for prestressed pipe stake core bore when bearing platform construction from blocking,
Step 1: being familiar with drawing before pile for prestressed pipe 4 is constructed, and carries out rationally matching stake, determines the top section piling of every pile, and handle
It is concentrated by region stacks.
Step 2: the sealing steel plate 1 of production 3mm thickness, the sealing plate size is according to stake core bore dimensioned；
Soil is filled by the lower part stake core bore of stake into stake core bore in order to prevent, and pile top such as uses opening pile using sealing pile top
Point, stake lower part also need to be blocked.
Step 3: stake core bore sealing is carried out with the sealing steel plate of 3mm thickness in the top section piling one end determined, seals steel plate
Be welded to connect with pile end plate 2 using interruption, every section of 3 length of weld seam is not less than 50mm, the height of weld seam cannot beyond pile end plate with
It prevents from destroying hush panel when pile follower, sealing steel plate is placed by the lower part of pile end plate；Sealing steel plate is sealing steel plate after being provided with
End bidding will when hanging to prevent going wrong.
Step 4: after bearing platform construction, cutting welding position between sealing steel plate and pile end board with hand-held cutting machine,
Sealing steel plate recycling is used as stake stem end plate.
Claims (3)
