Abstract
The invention discloses a reinforced connection method for a PHC (prestress high concrete) tubular pile. Connectors at the two ends of the PHC tubular pile are involved, wherein each connector consists of an end plate and a skirt piece; when the pile is connected, the two end plates are connected in a peripheral welding way. The method is characterized in that skirt boards are arranged in the skirt pieces in a sleeving way when the tubular pile is prefabricated, and are connected in a spot welding way, wherein the skirt board pieces outside the skirt boards are cut when the pile is connected; a plurality of cambered ribbed plates are welded outside the two skirt boards after the two end plates are connected in the peripheral welding way; the upper and lower connectors are integrally welded by virtue of the ribbed plates, so that the connection strength of the PHC tubular pile is strengthened. Compared with the prior art, the reinforced connection method has the advantages that high pulling resistance and high bending resistance are achieved, the connected PHC tubular pile can bear vertical force as well as horizontal force on the premise of meeting the pile manufacturing process requirement of preventing film clamping and mud leakage, the connection strength of the pile is strengthened, and a manufacturing process is simple, high in construction speed and overall structural performance and particularly suitable for the PHC tubular pile construction of inshore water transportation engineering.
Description
Technical field
The present invention relates to making and the technical field of construction of pile tube, specifically a kind of method that reinforces the connection for long piled wharf PHC pile tube.
Background technology
At present, long piled wharf engineering pile foundation all adopts marine piling ship to construct, and PHC pile tube adopts barge water transportation, and single-unit pile tube pile sinking length is maximum reaches nearly hundred meters, does not generally need to carry out pile extension, is conducive to guaranteeing pile foundation construction quality.But be substantially in land and water boundary, location, river levee shoal for offshore marine traffic engineering, part engineering ground is narrow again, according to floating piling scheme after heavy excavation, then difficulty is comparatively large, and soil excavation engineering quantity is large, exhausts the people and drains the treasury, unreasonable economically.Form land-based area according to backfill to construct PHC pile tube, then land pile sinking single-unit pile tube length is generally not more than 20m, need arrange 2 ~ 4 joints again.Because water body has corrosiveness to pipe pile joint, add tide bulge and fall, affect project durability, marine traffic engineering (particularly waters part) is extremely tight to PHC pipe pile joint quantity, quality control on construction, therefore suitably must reinforce this part pipe pile joint, to meet workmanship and life requirement.
The connector that PHC pile tube uses generally is made up of flange and skirt sheet; flange is arranged on the two ends of PHC pile tube; connect upper and lower pipe joint stake only the flange of connector end to be carried out welding the vertical applied force that can ensure pile tube; and the skirt sheet being arranged on pile tube two ends for preventing snap gauge or spillage in prefabricated PHC pile tube process; its thickness only has 2mm thick, and the connection be not used as between PHC pile tube is stressed.
The PHC pile tube of prior art connects, after pile extension the resistance to plucking of pile tube entirety and bending resistance poor, can not horizontal force be born, the requirement of structure stress cannot be met.
Summary of the invention
The object of the invention is a kind of method that reinforces the connection that PHC pile tube is provided for the deficiencies in the prior art, adopt the joint prefabricated tubular pile being provided with skirtboard, outside joint, weld several piece arc after cutting off skirt sheet during pile extension add powerful plate, not only meet and prevent card film, the stake technological requirement processed of spillage, and enhance resistance to plucking and the bending resistance of pile tube entirety after pile extension, cost of manufacture is low, be easy to promotion and implementation, improve the bonding strength between stake and stake, make the PHC pile tube after connecting can bear vertical vertical force and can bear horizontal force again, especially the PHC tube pile construction of offshore marine traffic engineering is applicable to.
The object of the present invention is achieved like this: a kind of method that reinforces the connection of PHC pile tube, comprise the connector being arranged on PHC pile tube two ends, connector is made up of end plate and skirt sheet, upper and lower two PHC pile tubes are connected by two end plates weld all around during pile extension, in skirt sheet, skirtboard is set with when being characterized in that PHC pile tube is prefabricated, skirtboard and skirt sheet are that spot welding is connected, during pile extension, the some skirt sheet be welded in outside skirtboard is cut off, two end plates weld all around adds powerful plate at two skirtboard external welding several piece arcs after connecting, add powerful plate upper and lower two connectors are welded as a whole, to increase PHC pile tube bonding strength; Described end plate and skirtboard and the reinforcement welding be arranged in PHC pile tube; Described skirtboard is be sleeved on the pipeline section in skirt sheet, its thickness G reatT.GreaT.GT5 mm; Described skirt sheet thickness≤2 mm.
The present invention compared with prior art has good resistance to plucking and bending resistance, meeting under the stake technological requirement processed preventing card film, spillage, make the PHC pile tube after pile extension can bear vertical vertical force and can bear horizontal force again, cost of manufacture is low, be easy to promotion and implementation, improve the bonding strength between stake and stake, manufacture craft is simple, speed of application is fast, overall structure is good, is especially applicable to the PHC tube pile construction of offshore marine traffic engineering.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the invention process illustration;
Fig. 3 is Fig. 2 top view.
Detailed description of the invention
Accompanying drawings 1, the present invention includes the connector 2 being arranged on PHC pile tube 1 two ends, and connector 2 is made up of end plate 3, skirt sheet 4 and skirtboard 5; Described skirtboard 5 is for being sleeved on pipeline section in skirt sheet 4 and with skirt sheet 4 for spot welding is connected; Described end plate 3 and skirtboard 5 and the reinforcement welding be arranged in PHC pile tube 1.
By following specific embodiment, the present invention is described in further detail.
Embodiment 1
Accompanying drawings 2 ~ accompanying drawing 3, the present invention makes like this and is connected: PHC pile tube 1(AB type) adopt φ 800 mm, skirtboard 5 thickness of its two ends connector 2 is 8mm, and height is that 250mm(is consistent with the height of skirt sheet 4); End plate 3 adopts φ 800 mm X15mm(thick); Skirt sheet 4 adopts 2mm(thick) X 250mm(is high), the snap gauge when setting of skirt sheet 4 is mainly for avoiding pile tube prefabricated and leakage.When PHC pile tube 1 is prefabricated, skirtboard 5 is sleeved in skirt sheet 4, skirtboard 5 with skirt sheet 4 for spot welding is connected, end plate 3 and skirtboard 5 and the reinforcement welding be arranged in PHC pile tube 1.
After completing stake processed, PHC pile tube 1 is transported to job site and carries out pile extension, the point skirt sheet 4 be welded in outside skirtboard 5 is cut off, two end plates 3 weld all around adds powerful plate 6 at two skirtboard 5 external weldings, four pieces of arcs after connecting, adding powerful plate 6 adopts 431.6mm(wide) X 350mm(is high) X 12mm(is thick), the connector 2 of upper and lower two PHC pile tubes 1 is welded as a whole.The present invention is after the weld all around pile extension of two end plates 3, add the pile tube connection adding powerful plate 6 in skirtboard 5 external welding, improve the bonding strength between stake and stake, make the upper and lower two PHC pile tubes 1 after pile extension can bear vertical vertical force and can bear horizontal force again, improve overall pulling test and the bending resistance of pile tube.
