[0030] The embodiments of the present utility model are described below in conjunction with the accompanying drawings.
[0031] like Figure 1 As shown, the utility model is a marking and positioning device for pile foundation construction in shallow water areas, comprising a fixing device 10 and a positioning assembly 20; wherein the fixing device 10 has a top end and a bottom end arranged along its length direction, and the bottom end is used to be inserted into a soil body 50 under a water body 40; the positioning assembly 20 is detachably arranged on the top end of the above-mentioned fixing device 10, and comprises a positioning mark 24, and the positioning mark 24 is staggered with the fixing device 10 in the vertical direction.
[0032] In the present application, the length of the fixing device 10 is greater than the depth of the water body 40. When the fixing device 10 is fixed in the soil 50 below the water body 40, the positioning component 20 is exposed to the water surface, that is, the positioning mark 24 is exposed to the water surface, which is convenient for the surveyor to observe; at the same time, the positioning mark 24 will not move with the rise and fall of the tide, and the position is more accurate; it can be understood that the position of the positioning mark 24 is aligned with the center of the pile body during the later piling construction. By staggering the positioning mark 24 and the fixing device 10 in the vertical direction, the position of the positioning mark 24 can be more conveniently checked before the piling construction, and it is also more convenient to adjust the position of the pile body according to the position of the positioning mark 24, so that its center is aligned with the positioning mark 24, ensuring that the pile body is accurately positioned.
[0033] Further, in a specific embodiment, Figure 2 As shown, the fixing device 10 includes at least one vertical rod 11, the bottom end of the vertical rod 11 is pointed and can be easily inserted into the soil 50;
[0034] Furthermore, if Figure 3 As shown, the positioning assembly 20 includes a sleeve 21, which is sleeved on the vertical pole 11; the sleeve 21 is provided with a connection hole, and the positioning device is fixed to the vertical pole 11 by fasteners passing through the connection hole. When in use, the vertical pole 11 is inserted into the soil 50, and then the sleeve 21 is sleeved on a height of the vertical pole 11 as required, so that the positioning assembly 20 and the positioning mark 24 can be exposed to the water surface, which is convenient to install and can be applied to situations with different depths of the water body 40, thereby improving the applicability of the overall device.
[0035] In some specific embodiments of the present application, there is no limit to the number of vertical poles 11, which can be one or more. The number of sleeves 21 is the same as the number of vertical poles 11. On the one hand, the fixing device 10 can be more firmly fixed to the soil 50, and on the other hand, the positioning assembly 20 can be more firmly fixed to the fixing device 10.
[0036] Furthermore, if Figure 3 As shown, the positioning assembly 20 also includes a connecting member 22 and a deformable member 23. The connecting member 22 is respectively connected to both sides of the sleeve 21, and the deformable member 23 is connected to the connecting member 22. The connecting member 22, the sleeve 21 and the deformable member 23 are enclosed to form a closed shape. The positioning mark 24 is set on the deformable member 23.
[0037] In the present application, the shape and size of the closed shape formed by the connecting member 22, the sleeve 21 and the deformable member 23 are set according to the shape and size of the pile body to be constructed. Preferably, the shape and size of the closed shape are larger than the shape and size of the pile body; when the center of the pile body is aligned with the positioning mark 24 and moves downward, it can drive the positioning mark 24 to move downward, causing the deformable member 23 to deform until it breaks. At this time, the pile body can smoothly pass through the closed shape without colliding with the connecting member 22, the sleeve 21 and the upright 11, avoiding damage to the connecting member 22, the sleeve 21 and the upright 11, so that it can be used in a turnover manner.
[0038] Furthermore, the connecting member 22 is arc-shaped or L-shaped, and the positioning mark 24 is arranged in the middle of the deformable member 23. In other words, the shape enclosed by the connecting member 22, the sleeve 21 and the deformable member 23 is a part of a circle or a square, which can be respectively suitable for piles with circular cross-sections and piles with square cross-sections.
[0039] In a specific embodiment, the cross-section of the pile to be constructed is circular, the connecting member 22 is arc-shaped, and the connecting member 22 is connected to both sides of the casing 21 to form a semicircular shape with an opening; the two ends of the deformable member 23 are respectively connected to the free ends of the connecting member 22, so that the three are connected to form a closed semicircle, and the radius of the semicircle is greater than the radius of the pile to be constructed. The positioning mark 24 is set at the center of the deformable member 23. When the axis of the pile body is aligned with the positioning mark 24 and moves downward, the pile body and the connecting member 22, the casing 21 and the vertical pole 11 do not contact each other, so as to prevent the three from being damaged by impact.
[0040] In another specific embodiment, the cross-section of the pile to be constructed is square, the connecting piece 22 is L-shaped, and the connecting piece 22 is connected to both sides of the sleeve 21 to form a square with one end open; the two ends of the deformable piece 23 are respectively connected to the free ends of the connecting piece 22, so that the three are connected to form a closed square, and the cross-sectional shape of the square is larger than half of the cross-sectional shape of the pile to be constructed, and the positioning mark 24 is set at the center of the deformable piece 23. When the axis of the pile body is aligned with the positioning mark 24 and moves downward, the pile body and the connecting piece 22, the sleeve 21 and the vertical pole 11 do not contact each other, so as to prevent the three from being damaged by impact.
[0041] In some other embodiments of the present application, the shape and size of the connecting member 22 can be set according to the shape and size of the pile body to be constructed. As long as the connecting member 22, the sleeve 21 and the deformable member 23 are combined to form a closed shape and a shape larger than the shape of the pile body to be constructed, turnover can be achieved.
[0042] Furthermore, the connector 22 is provided with a connecting portion, and both ends of the deformable member 23 are detachably connected to the connecting portion. In the present application, the deformable member 23 is made of a material that is easy to break. When it is broken by the impact of the pile body, a new deformable member 23 can be reinstalled to achieve the circumferential use of the entire device, which is conducive to saving costs and production time.
[0043] Preferably, the connecting portion is a reverse hook 221, and both ends of the deformable member 23 are provided with snap rings 231 that match the reverse hook 221. The snap rings 231 can be inserted into the reverse hook 221 and clamped at the hook position; this design can realize convenient installation and replacement of the deformable member 23 and the connecting member 22.
[0044] Furthermore, if Figure 1 As shown, the marking and positioning device for pile foundation construction in shallow water areas proposed in the present application also includes a limiting device 30 detachably arranged on the fixing device 10, and the limiting device 30 is arranged below the positioning component 20, so that the fixing device 10 can be firmly fixed to the soil 50 and is not easily moved and offset with the water flow.
[0045] In a specific implementation, Figure 4 As shown, the limiting device 30 includes a limiting tube 31, a limiting member 32 and a support plate 33 which are connected in sequence. The limiting tube 31 is sleeved on the fixing device 10, and the support plate 33 is perpendicular to the fixing device 10 and is located outside the projection of the closed shape, that is, the support plate 33 is arranged outside the moving route of the pile body; when in use, the limiting device 30 is fixed to the bottom of the fixing device 10 by the limiting tube 31, so that the support plate 33 can contact with the soil 50. Specifically, the support plate 33 can be attached to the surface of the soil 50, or it can extend into the interior of the soil 50. There is enough contact area between the support plate 33 and the soil 50, which can more effectively prevent the fixing device 10 from moving.
[0046] Preferably, the limit member 32 is aligned with the connecting member 22, that is, the shape of the limit member 32 is the same as that of the connecting member 22. Preferably, the limit member 32 is larger than the connecting member 22 so that the support plate 33 avoids the moving path of the pile body; when the pile body moves downward during construction, it passes through the connecting member 22 and the limit member 32 successively, which can prevent the pile body from shifting during movement; and when the pile body shifts, it will hit the limit member 32, and the limit member 32 can form resistance to prevent the pile body from continuing to move downward, which is convenient for the operator to discover in time and improves the accuracy of the pile body construction position.
[0047] In a specific embodiment, the deformable member 23 is made of a rubber band, which is a common and readily available material and is easily deformed and broken under the impact of the pile body.
[0048] In a specific embodiment, the present application is used for pile foundation construction in shallow water areas. The cross-section of the pile to be constructed is circular. The vertical pole 11, the connecting member 22 and the limit member 32 are all made of steel bars. The connecting member 22, the sleeve 21 and the deformable member 23 enclose a closed shape of a semicircle, and its radius is 100 mm greater than the radius of the pile body; the positioning mark 24 is tied to the deformable member 23 with red silk, and the deformable member 23 is made of a rubber band. A clamp ring 231 is provided at both ends of the rubber band. When the clamp ring 231 is clamped on the reverse hook 221 of the connecting member 22, the rubber band is in a tensioned state; when in use, the vertical pole 11 is inserted into the soil 50, and the vertical pole 1 The length of the extension into the soil 50 is not less than 500 mm, so that the limiting device 30 is attached to the surface of the soil 50; the positioning assembly 20 is installed on the vertical pole 11, so that the positioning assembly 20 is exposed to the water surface, and the positioning mark 24 is checked to be in the set position and the vertical pole 11 is in the vertical state; when piling, the position of the pile body is adjusted so that its axis is aligned with the positioning mark 24, and as the pile body moves downward, the deformable member 23 is driven to stretch until it breaks; after the piling is completed, the fixing device 10 and the limiting device 30 are moved to other intended construction locations, and new deformable members 23 and positioning marks 24 are installed so that they can be used again, thereby realizing the turnover of the device and saving construction costs.
[0049] The utility model can locate and measure the intended construction position more conveniently by setting the positioning component, reducing the difficulty of positioning and improving the efficiency and accuracy of pile foundation construction; by finely designing the shape of the positioning component and using the positioning mark and the deformation piece to match, the device can be accurately positioned while avoiding damage, and it can be used after only replacing the deformation piece and the positioning mark, effectively reducing the construction cost. The overall device has a simple structure, is easy to install and disassemble, and has a low processing cost.
