Abstract
The invention relates to the field of pile foundation construction, in particular to a concrete prefabricated pile rapid sinking method. The concrete prefabricated pile rapid sinking method includes the following steps: a step 1, machining a steel bar into a circular hoop, wherein the inner diameter of the circular loop is equal to the outer diameter of a prefabricated pile; a step 2, welding the circular loop on the outer periphery of the top of a pile head end plate of the prefabricated pile; a step 3, determining and rechecking a pile position, and performing pile sinking construction work; and a step 4, sinking a first joint of the prefabricated pile, and then connecting and sinking next joints of the prefabricated pile joint by joint till the pile head end plate reaches to a designed position, and completing pile sinking construction. The concrete prefabricated pile rapid sinking method can use local materials, is low in cost, is low in processing difficulty, has high operability, is good in pile sinking effect, and can greatly improve the pile sinking efficiency and quality.
Description
Technical field
The present invention relates to pile foundation construction field, the quick pile sinking process of specifically a kind of concrete precast pile.
Background technology
Pile foundation in skyscraper, bridge and port engineering using extremely wide, its have high capacity, good stability, settling amount little and it is uniform, be easy to the outstanding features such as mechanized construction, strong adaptability.
Then prefabricated tubular pile can be transported at stake position at the construction field (site) or prefabrication, then Jing hammer modes squeeze into stratum design attitude, i.e. piling construction.Pile driving method by hammer advantage is that equipment is simple, pile sinking speed is fast, low cost.However, when the layer of sand that soil property is harder, needs run through is thicker, pile sinking is extremely difficult, effect is reduced.At present frequently with the pile top that a steel plate processing is welded in pile crown position solving the above problems, but as Shen Ding exists《Engineering technology》（13rd phase in 2013）" brief talking the FAQs and countermeasure of the pile foundation construction " text delivered is pointed out, when stake sinkage does not reach design requirement, using large-tonnage pile frame and can adopt heavy hammer and low strike method pile sinking, and problem is that effect is still low, and it is damaged to easily cause pile crown.
The content of the invention
It is an object of the present invention to provide it is a kind of it is simple and practical, suitable for hard soil layer or the high-quality through operating modes such as layers of sand, the pile sinking process of high effect.
In order to achieve the above object, the present invention is realized in：
A kind of quick pile sinking process of concrete precast pile, comprises the steps,
Step 1, with one annular anchor ear of steel bar meter, the internal diameter of the annular anchor ear is equal with the stake external diameter of prefabricated tubular pile；
Step 2, by annular anchor ear full weld prefabricated tubular pile pile crown end plate top periphery；
Step 3, determine and check stake position, carry out piling construction operation；
After the completion of the first section pile sinking of step 4, prefabricated tubular pile, section by section simultaneously piling construction subsequently respectively saves prefabricated tubular pile for connection, and straight pile crown end plate reaches design attitude, completes piling construction.
The quick pile sinking process of described concrete precast pile, the diameter of reinforcing bar used by step 1 is not less than 18mm.
The quick pile sinking process of described concrete precast pile, before the pile crown end plate of prefabricated tubular pile pile top is equipped with.
This quick pile sinking process material therefor is easy to gather materials on the spot, with low cost；Process technology difficulty is low, after the full weld anchor ear of pile end plate periphery, foremost outside contacts the linear contact lay become between anchor ear and the soil body with the face between the soil body to original pile body, so greatly reduce frictional force of the pile body just between section and the soil body, so that suffered resistance is less when pile body is penetrating hard soil layer, through sandstone soil layer, thus it is with very strong operability；And pile sinking effect is good, can be good at improving pile sinking efficiency and quality.
Description of the drawings
Fig. 1 is the position view of anchor ear in this pile sinking process.
Specific embodiment
The present invention is further illustrated below by way of specific embodiment.
As shown in figure 1, a kind of quick pile sinking process of concrete precast pile, comprises the steps,
Step 1, with one annular anchor ear 1 of steel bar meter, the internal diameter of the annular anchor ear 1 is equal with the stake external diameter of prefabricated tubular pile 2；
Step 2, by the full weld of annular anchor ear 1 prefabricated tubular pile 2 the top periphery of pile crown end plate 3；
Step 3, determine and check stake position, carry out piling construction operation；
After the completion of the first section pile sinking of step 4, prefabricated tubular pile 2, section by section simultaneously piling construction subsequently respectively saves prefabricated tubular pile for connection, until first segment pile crown end plate reaches design attitude, completes piling construction.
The quick pile sinking process of described concrete precast pile, the diameter of reinforcing bar used by step 1 is not less than 18mm.
The quick pile sinking process of described concrete precast pile, before the pile crown end plate 3 of prefabricated tubular pile 2 pile top is equipped with.
This quick pile sinking process material therefor is easy to gather materials on the spot, with low cost；Process technology difficulty is low, after the full weld anchor ear of pile end plate periphery, foremost outside contacts the linear contact lay become between anchor ear and the soil body with the face between the soil body to original pile body, so greatly reduce frictional force of the pile body just between section and the soil body, so that suffered resistance is less when pile body is penetrating hard soil layer, through sandstone soil layer, thus it is with very strong operability；And pile sinking effect is good, can be good at improving pile sinking efficiency and quality.
