Description

Deepwater steel pipe pile connecting device

Technical Field

The utility model belongs to the technical field of the bridge construction technique and specifically relates to a deep water steel-pipe pile connecting device is related to.

Background

In the construction of the steel pipe pile of the deepwater trestle, because the steel degree and the stability of the steel pipe pile are poor under the condition of deeper water, the transverse connection needs to be added in the water, and the conventional construction process is that the steel pipe pile is driven into the water and then is welded or connected by bolts by a diver, so that the construction cost and the construction time are increased, and the deepwater construction has great potential safety hazards.

Disclosure of Invention

The utility model relates to a solve present steel-pipe pile and squeeze into submarine back, will come underwater welding or bolted connection with diver, increase construction cost and time, there is the problem of great potential safety hazard in deep water construction moreover, provide a safe and reliable, need not diver's underwater operation, reduce the deep water steel-pipe pile connecting device of construction cost and time.

In order to achieve the above purpose, the utility model adopts the following technical scheme: deep water steel-pipe pile connecting device, including a plurality of steel-pipe piles that sink into the aquatic, still include connecting device, connecting device locate between two steel-pipe piles, connecting device includes that connecting rod, mirror image locate two steel-pipe piles on the spill rectangular post, the connecting rod both ends be equipped with the bolt board respectively, spill rectangular post opening part be equipped with inside turn-ups and form the spout, the rectangular bottom of the post of spill is equipped with the baffle, the bolt board can reciprocate in the spout. According to the scheme, the transverse connection position of the steel pipes is determined according to different water depths, so that the length of the concave rectangular columns is determined, the length of the connecting rod can be determined according to the transverse distance of the steel pipes, and therefore the bolt plates at the two ends of the connecting rod (the width of the bolt plates is larger than the opening width of the concave rectangular columns and cannot fall out) can move up and down in the sliding groove, and the connecting rod is hoisted by using tools such as ropes and the like up and down, so that a diver is not required to perform underwater operation.

Preferably, the end face of the latch plate, which is far away from the connecting rod, is an inclined plane. The connecting rod reciprocates the in-process, and both ends balance is very difficult to keep, therefore the bolt board makes the connecting rod blocked easily with the spout bottom surface if the clearance undersize, if the clearance is too big, does not play the effect of connecting two fixed steel-pipe piles again, and this scheme bolt board adopts the inclined end face (the diagonal angle length of two bolt boards has reduced), the condition that reducible connecting rod was blocked to guarantee the connection fixed state of two steel-pipe piles.

Preferably, the bottom of the concave strip-shaped column is provided with a connecting port, two sides of the connecting port are uniformly contracted from top to bottom into an isosceles inverted trapezoid with an upper bottom larger than a lower bottom, and the shape of the plug pin plate is matched with the connecting port. The isosceles inverted trapezoid (the V-shaped bottom forms a plane) has the function of centripetal adjustment, so that the pin plates at the two ends of the connecting rod can be centripetally aligned, and the vertical connection state of the connecting rod and the two steel pipe piles is kept.

The structure principle of the scheme is as follows: calculating the position of a transverse connecting port according to the depth of water and the depth of soil entering of the steel pipe pile, vertically welding a concave strip column (chute) and a connecting port on the steel pipe pile, and driving the steel pipe pile (paying attention to the direction of the interface when the steel pipe pile is driven), wherein the chute can adopt 25# channel steel, so that the position of a connecting rod bolt plate when the connecting rod bolt plate slides in can be conveniently controlled; the connecting port and the connecting position of the sliding chute are the same in width, then the connecting port is contracted downwards (the port is gradually changed from 3 cm to 2 cm so as to be convenient to be clamped with the bolt plate), after two steel pipe piles are driven into the connecting pipe according to the designed positions, the verticality (error and timely adjustment) and the distance between the two steel pipe piles are detected to determine the length of the connecting rod; after the connection is determined, the connecting rods are lifted by the two ends of the steel wire ropes and placed into the sliding grooves, the two ends of the steel wire ropes are equally placed downwards into the connecting ports, and when the engineering is completed and needs to be dismantled, the steel wire ropes at the two ends can be lifted to lift the connecting rods, so that connection is released.

Therefore, the utility model discloses following beneficial effect has: safe and reliable, need not diver's underwater operation, reduce construction cost and time, repeatedly usable.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, the deepwater steel pipe pile connection device comprises a plurality of steel pipe piles 1 immersed in water and a connection device, wherein the connection device is arranged between two steel pipe piles 1 and comprises a connection rod 2 and concave rectangular columns 3 arranged on the two steel pipe piles 1 in a mirror image manner, two ends of the connection rod 2 are respectively provided with a bolt plate 4, an inward flanging is arranged at the opening of each concave rectangular column 3 to form a chute, the bottom of each concave rectangular column 3 is provided with a baffle plate 5, and the bolt plates 4 can move up and down in the chutes;

the end surface of the bolt plate 4 far away from the connecting rod 2 is an inclined surface;

the bottom of the concave rectangular column 3 is provided with a connecting port 6, two sides of the connecting port 6 are uniformly contracted from top to bottom into an isosceles inverted trapezoid with an upper bottom larger than a lower bottom, and the shape of the bolt plate 4 is matched with the connecting port 6.

The concrete implementation process is that when the scheme is implemented, the position of the transverse connecting port is calculated according to the water depth and the soil penetration depth of the steel pipe pile 1, and the steel pipe pile is driven into the steel pipe pile 1 after the concave rectangular columns 3 and the connecting ports 6 are vertically welded on the steel pipe pile 1; after the two steel pipe piles 1 are driven into the pile according to the designed positions, detecting the verticality (error and timely adjustment) and the distance of the two steel pipe piles 1 to determine the length of the connecting rod 2; after the determination, hoisting the connecting rod 2 by using two ends of a steel wire rope and placing the connecting rod into the chutes of the concave long columns 3, and placing the bolt plates 4 at two ends of the connecting rod 2 into the connecting port 6 downwards along the chutes;

when the engineering is finished and needs to be dismantled, the steel wire ropes at the two ends are lifted to lift the connecting rod 2, and the connection is released.
