Abstract
The utility model relates to a high-strength concrete prestress prefabricated (PHC) sheet pile which comprises a main reinforcing bar, a spiral stirrup and PHC tubular pile bodies made of concrete. The PHC sheet pile is characterized in that lock catch connecting components are symmetrically arranged on peripheral surfaces of two sides of each PHC tubular body, and the plurality of PHC tubular pile bodies are connected through the lock catch connecting components to form the PHC sheet pipe. The PHC sheet pile has the advantages that the problem that ordinary PHC tubular piles are not applicable to the sheet pile structure is solved by precasting of connecting pieces in a reinforcement cage and post-welding of the lock catch connecting components on the connecting pieces; and due to the fact that manufacturing cost of the PHC tubular piles is low and different pile sinking technologies can be selected according to different construction geological conditions, the construction technology of the PHC sheet pile with the tubular piles as the main body is simple, recycling is not needed after the usage, the defect that engineering cost of steel sheet piles is high is overcome, and construction efficiency is improved.
Description
Technical field
The utility model belongs to the architectural construction stake, relates in particular to a kind of PHC sheet pile that is applicable in building deep foundation ditch and retaining wall structure construction.
Background technology
PHC pile tube (high-strength concrete prestressing force prefabricated tubular pile).In building deep foundation ditch and retaining wall structure construction, usually adopt the steel sheet pile structure.Because the steel sheet pile structure has the native stagnant water effect of good gear, and it is simple to set technique, therefore is widely used.In the construction of part sheet-pile wharf, the steel sheet pile structure also begins to try out and obtain good effect at present.But the steel sheet pile cost is higher, needs after finishing using to carry out recycling with a large amount of manpowers and plant equipment.And along with the raising of depth of penetration, make steel sheet pile and the increase of the frictional resistance between ground on every side, reclaim operation and become difficult, need to expend enormous expenditure, greatly improved construction costs.Dark for depth of penetration and the steel sheet pile that is difficult to reclaim can only be taked: as in underground shallow place, this steel sheet pile to be cut off, can be deposited in that underground part is kept intact and the method for keeping somewhere.The common PHC pile tube that generally uses at present has anti-bending strength preferably, and cost is low, does not need after use to reclaim, and is suitable as very much the sheet pile main component and uses.But because the PHC pile tube does not have buckle structure, therefore be difficult to use as sheet pile in building deep foundation ditch and retaining wall structure construction.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of PHC sheet pile to be provided, and realizes the structure that is connected by snap close between pile body and pile body, namely applicable in building deep foundation ditch and retaining wall structure construction.Combine the advantage of steel sheet pile and common PHC pile tube, and it is high and need to expend that enormous expenditure reclaims and deficiency that common PHC pile tube can not use as sheet pile to solve the steel sheet pile cost of manufacture.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of PHC sheet pile, comprise the PHC pile tube main body that is consisted of by main muscle, spiral stirrup and concrete, it is characterized in that: described PHC pile tube main body two most peripheral edge surface are arranged with the snap close connecting elements, and described some PHC pile tube main bodys connect into whole PHC sheet pile by the snap close connecting elements respectively.
Described snap close connecting elements comprises junction plate, male snap close and female snap close, described junction plate is symmetrically placed in two most peripheral edge surface of PHC pile tube main body, described junction plate is affixed by connecting reinforcement and spiral stirrup, and described male snap close and female snap close are affixed with junction plate respectively.
Described PHC pile tube main body is the hollow square pile that the rounded hollow circle stake of shape of cross section or shape of cross section are square.
Beneficial effect: by built-in connection in reinforcing cage, rear weldering snap close connecting elements, solved the problem that common PHC pile tube can not be applied to sheet pile structure on connector.Simultaneously, due in use, main body pile tube part is mainly born tensile stress to a native side, carry on the back a native side and mainly bear compressive stress, therefore can arrange by the configuration consumption and the cross section that change the main muscle of PHC stake, can change the tension of cross section different piece and a compressive property, thereby better bring into play individual material properties, improve the anti-bending strength of common PHC pile tube.According to different construction needs, can change the prestressed concrete pipe pile as king pile into prestressed concrete square pile, produce a desired effect equally, realize the flexible Application of PHC sheet pile.Because the PHC pile tube is made cheap, can select different process for sinking according to different construction geology conditions, therefore the PHC sheet pile construction technology take this pile tube as main body is simple, and does not need after using to reclaim, efficiently solve the high deficiency of steel sheet pile construction cost, and improved efficiency of construction.
