Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, the utility model provides an auxiliary device for sinking a prefabricated square pile 1, which comprises a hoisting chain 4 with a first end fixed to a pile driver 5, wherein a second end of the hoisting chain 4 is formed with a circular ring for the square pile 1 to wind around, the second end of the hoisting chain 4 at least extends to the middle section of the square pile 1, and the end of the square pile 1 is sleeved with a sleeve head 2 fixed to the pile driver 5. The construction of 1 pile sinking of square pile generally adopts the mode of hammering to sink to design elevation, and in the work progress, square pile 1 often receives the loss of very big degree, and the straightness that hangs down often unsatisfied design standard requirement simultaneously, causes effective bearing capacity not enough, overlaps first 2 covers on 1 top of square pile during the construction, overlaps first 2 parcel and lives 1 upper portions of square pile, overlaps first 2 inner walls and the laminating of square pile 1, the tip of protection square pile 1. The first end of the hoisting chain 4 is fixed on the pile driver, then the second end is used for binding the square pile 1, so that the circular ring of the hoisting chain is tightly bound with the square pile 1 for fixing, and then the manual regulation of the verticality is matched for pile sinking operation. In the embodiment, the sleeve head 2 is made of a steel plate with the thickness of 1-2 cm.
Specifically, the second end of the hoisting chain 4 is provided with a fixing buckle, and the hoisting chain 4 surrounds the square pile 1 for a circle to form the circular ring and is fixed on the hoisting chain 4 through the fixing buckle. This 4 second ends of hoist and mount chain are adjusted at will according to the size of square pile 1 around establishing the ring that forms, and with fixed knot buckle establish on hoist and mount chain 4 after the periphery of square pile 1 with hoist and mount chain 4 cramps, this fixed mode suitability is strong, does benefit to the turnover.
Preferably, the sleeve head 2 is sealed at one end by a fixing plate, and a connecting piece for connecting the pile driver 5 is fixed on the back of the fixing plate. The connecting piece can select different forms according to the formation of the connecting position of the pile driver 5, needs to be favorable for the hammering construction of the pile driver 5, and is connected with the pile driver 5, so that the positioning is more accurate when the pile driver 5 hammers, and the damage to the end part of the square pile 1 is reduced.
Specifically, the connecting piece is a connecting plate 3 with an I-shaped section, and the end face of the connecting plate 3 is fixed with the fixing plate. This connecting plate 3 can adopt the steel sheet preparation, and the chuck 5 of pile driver directly presss from both sides and establishes in the web position department of connecting plate 3 during the construction, carries out hammering pile sinking again, makes chuck 5 be difficult for producing the aversion because of the hammering to the position of square pile 1 plays certain positioning action.
Preferably, the section of the sleeve head 2 is square, and the section area is larger than that of the top end of the square pile 1. This pullover 2 can play the guard action to 1 tip of square pile, and the pile driver is direct to be connected with connecting plate 3 and has played the effect of location, avoids square pile 1 to damage and the reverse work, has improved the efficiency of construction of pile sinking.
Specifically, the length of the side of the sleeve head 2 is determined according to the cross-sectional area of the square pile 1, and is slightly larger than the cross-sectional area of the square pile 1, in this embodiment, the length of the side of the sleeve head 2 is 41cm, and the total length of the sleeve head 2 and the connecting plate 3 is 60 cm. As shown in fig. 3, the length of the hoisting chain 4 depends on the length of the square pile 1, and in this embodiment, the length of the hoisting chain 4 is 2 m. The hoisting chain 4 is made of common thick iron chains, and has the advantages of simple and easily obtained materials and low material cost.
During pile sinking operation, the pile driver lifts by crane square pile 1, carries out pile sinking operation afterwards, and pullover 2 carries out effectual parcel and fixed to square pile 1, protection square pile 1 that can be fine at the hammering in-process, reduces the harm that hammering in-process square pile 1 self caused, can play the effect of rectifying simultaneously at the pile sinking in-process for the straightness accords with the design standard that hangs down after the pile sinking is accomplished. The hoisting chain 4 plays a role in fixing the square pile 1 in the pile sinking process, the hoisting chain 4 is removed to continue operation when the pile sinking is half, and the sleeve head 2 can be detached after the pile sinking operation is completed according to the design specification.
The utility model solves the technical problems that the verticality is difficult to control and the pile head is easy to damage during pile driving in the prior art by sleeving the sleeve head on the square pile and binding the hoisting chain to assist in pile driving during pile driving. The utility model improves the precision and efficiency of pile sinking, effectively controls the verticality of the pile sinking, improves the quality of engineering entities, avoids the risk of rework, greatly accelerates the construction progress of the engineering and controls the construction cost.
The parts not involved in the present invention are the same as or can be implemented by the prior art. Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
