Detailed Description
The invention will be described in further detail with reference to the following drawings and embodiments:
as shown in fig. 1, the positioning device for steel pipe pile construction in a high-pile wharf comprises a pile leg 1, a pile leg 2, a pile leg 3, a pile shoe 4, a horizontal support 5, a water pump 6, a rotating base 7, a rotating arm 8, a positioning snap ring 9, a GPS locator 10 and an inclinometer 11.
The regular triangle positioning frame is formed by connecting three cylindrical steel pile legs 1, 2, 3 and three horizontal steel horizontal braces 5. The lower ends of the pile leg 1, the pile leg 2 and the pile leg 3 are all connected with a pile shoe 4. The included angles among the pile legs 1, 2 and 3 are all 60 degrees.
The diameters of the pile leg 1, the pile leg 2 and the pile leg 3 are the same. The diameter of the pile shoe 4 is larger than the diameters of the pile leg 1, the pile leg 2 and the pile leg 3. According to the functional requirement, spud leg 1, spud leg 2, spud leg 3 are inside can set up a plurality of cabins, and this embodiment has set up 3 cabins, and the setting up of many cabins structure can increase the broken cabin stability of triangle-shaped locating rack. The lower part of each pile leg is provided with a water pump 6, and the water pump 6 carries out water injection and drainage operation through an opening at the upper end of the pile leg. After the triangular positioning frame is dragged to a designated position through the dragging wheel, water is injected into the pile leg 1, the pile leg 2 and the pile leg 3 through the water pump 6, so that the pile shoe 4 is inserted into the seabed by a certain depth under the action of gravity.
The rotating base 7 is fixed on the pile leg 1 and can rotate a certain angle left and right in the horizontal direction. The rotary base 7 is connected with a rotary arm 8, and the rotary arm 8 is rigidly connected with the rotary base 7 and can rotate in a horizontal plane along with the rotary base. The rotating arm 8 is of a truss structure and provides a supporting effect in the positioning and driving process of the steel pipe pile. The end part of the rotating arm 8 is connected with a positioning snap ring 9, and the circle center of the positioning snap ring 9 is the geometric centroid of the regular triangle positioning frame. Because the center of the steel pipe pile is consistent with the geometric centroid of the regular triangle positioning frame, the influence of eccentric acting force can be reduced in the positioning and driving process of the steel pipe pile, and the stress distribution of the three pile legs of the positioning frame is uniform. The positioning clamp ring 9 can vertically rotate around the central line of the rotating arm 8 to position the inclined pile. The steel pipe pile to be driven into the seabed is fixed through the positioning snap ring 9. The positioning snap ring 9 can be opened and closed to fix the steel pipe pile to be driven.
The positioning device for the steel pipe pile construction of the high-pile wharf can position both a straight pile and an inclined pile. The end part of the positioning snap ring 9 connected with the rotating arm 8 is provided with a GPS locator 10 and an inclinometer 11. The GPS locator 10 is used for determining the position of the steel pipe pile position, and the inclinometer 11 is used for determining the inclination angle of the steel pipe inclined pile.
After the steel pipe pile is driven into the operation, water is discharged through a water pump 6 arranged in the pile leg 1, the pile leg 2 and the pile leg 3, the pile shoe 4 of each pile leg is pulled out by means of buoyancy of the pile leg 1, the pile leg 2 and the pile leg 3, and the triangular positioning frame is moved to a new pile position.
The pile leg 1, the pile leg 2 and the pile leg 3 of the high-pile wharf steel pipe pile construction positioning device are all larger than the design elevation of the steel pipe pile after positioning and driving, the bottom elevations of the three transverse steel horizontal struts 5 are at least larger than the design elevation of the steel pipe pile after positioning and driving by more than 0.5 m, and after the steel pipe pile is driven into a seabed through the triangular positioning frame, pile cutting or pile connecting is carried out in the triangular positioning frame, so that the top elevation of the steel pipe pile meets the design elevation requirement. The pile shoe 4 is pulled out through drainage of the water pump 6, and at the moment, the bottom elevation of the transverse horizontal support 5 of the triangular positioning frame is higher than the designed top elevation of the steel pipe pile, so that the positioning frame can move smoothly.
The above-described embodiments are merely illustrative of the principles and utilities of the present application and are not intended to limit the application. Any person skilled in the art can modify or change the above-described embodiments without departing from the spirit and scope of the present application. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present disclosure be covered by the claims of the present application.
