Example Embodiment

[0033] Example 1:

[0034] like figure 1 , figure 2 As shown, in this embodiment, a method for positioning the anchor piles adjacent to the caisson in water, the front anchor piles 1 located on the upstream surface of the caisson 5 and the rear anchor piles located on the downstream surface of the caisson 5 are arranged in the implantation area of ​​the caisson 5 Pile 2, make the caisson 5 sink in the area surrounded by the front anchor pile 1 and the rear anchor pile 2, and the distance between the front anchor pile 1 and the caisson 5 is between 30cm and 100cm, so The distance between the rear anchor pile 2 and the caisson 5 is between 30cm and 100cm.

[0035] Implant the front anchor pile 1 and the rear anchor pile 2 into the river bed 4 respectively, such as image 3 , Figure 4 As shown, after the front anchor pile 1 and the rear anchor pile 2 are installed, the caisson 5 is lowered and implanted. The use of the front anchor pile 1 and the rear anchor pile 2 can red...

Example Embodiment

[0037] Example 2:

[0038] On the basis of the above embodiment, in this embodiment, both the front anchor pile 1 and the rear anchor pile 2 are steel pipe piles 6 . The steel pipe pile 6 is an existing structure, which can be used directly without secondary processing, and is easy to be driven into the riverbed 4, which is beneficial to improve the construction efficiency. In this embodiment, other undescribed contents are the same as those in the above-mentioned embodiment, and thus are not described repeatedly.

Example Embodiment

[0039] Example 3:

[0040] like Figure 5 , Image 6 As shown, on the basis of the above embodiment, in this embodiment, the front anchor pile 1 is formed by connecting two steel pipe piles 6 through a plurality of connecting rods 7 . The rear anchor pile 2 is formed by connecting two steel pipe piles 6 through several connecting rods 7 .

[0041] The hardness of the river bed 4 is not high, and there is usually silt on the surface of the river bed 4. After the steel pipe pile 6 is driven into the river bed 4, there will be a risk of loosening and tilting under the action of the water flow. Two steel pipe piles 6 are used and connected through the connecting rod 7 The front anchor pile 1 and the rear anchor pile 2 are connected to make the front anchor pile 1 and the rear anchor pile 2, which can increase the number of fulcrums after the front anchor pile 1 and the rear anchor pile 2 are driven into the riverbed 4, thereby increasing the front anchor pile 1 and the rear anch...

Abstract

The invention discloses an underwater open caisson neighboring anchor pile positioning method and structure. The underwater open caisson neighboring anchor pile positioning method and structure is characterized in that a front anchor pile located on the upstream face of an open caisson and a rear anchor pile located on the downstream face of the open caisson are arranged in an open caisson landingarea to allow the sinking of the open caisson to be performed in an area formed by the front anchor pile and the rear anchor pile in an enclosed manner, the distance between the front anchor pile andthe open caisson is 30-100cm, and the distance between the rear anchor pile and the open caisson is 30-100cm. The underwater open caisson neighboring anchor pile positioning method and structure hasthe advantages that the underwater open caisson neighboring anchor pile positioning method and structure is clear in force transmission structure, short in force transmission distance and the like; compared with a traditional remote anchorage pier positioning system, the underwater open caisson neighboring anchor pile positioning method and structure can evidently reduce the scale of an open caisson positioning system and save implementation cost; due to the fact that the front anchor pile and the rear anchor pile are close to the open caisson, the open caisson can be forcibly constrained to move along the water flow direction, open caisson deviation can be inhibited effectively, open caisson inclination risks are lowered, and open caisson positioning precision and mounting quality are increased.

Description

technical field [0001] The invention relates to the technical field of caisson construction, in particular to a positioning method and a positioning structure for anchor piles adjacent to a caisson in water. Background technique [0002] Water caissons are widely used in the construction of large bridge foundations. Due to the action of the flow velocity of river water (river water or sea water), the caisson structure with larger size is often subjected to larger water flow force, which brings great difficulties to the positioning and implantation stability of the caisson on the water. The anchor pier in the traditional anchor pier positioning system is generally more than 100m away from the caisson to keep away from the scouring range of the caisson, and the long-distance wire rope pulley system or the steel strand jack tensioning system is used to connect the anchor pier and the caisson, so as to realize the alignment of the caisson. positioning and adjustment functions. ...
