The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 and fig. 2, the all-weather marine piling construction elevation calibration integrated device provided by the utility model comprises a post 1 vertically installed on a piling hull 100, wherein a measurement scale 2 is arranged on the post 1, and the measurement scale 2 is fixed at the middle upper position of the post 1. The lower part of the post 1 is provided with a platform 3 for placing a locator 5. In the utility model, the platform 3 can slide up and down for a certain distance relative to the marker post 1. Because the marker post 1 is fixed on the ship body 100, and the positioner 5 is positioned on the platform 3, when the platform 3 slides up and down relative to the marker post 1, the positioner 5 adjusts a certain height up and down relative to the ship body 100.

As shown in fig. 2, vertical shrinkage pool 10 has been seted up to 1 lower part lateral wall of sighting rod, and 3 bottoms of platform are equipped with the bolt 31 of taking nut 32, vertical shrinkage pool 10 is passed at the top of bolt 31, because the diameter of the top nut of bolt 31 is greater than the internal diameter of vertical shrinkage pool 10, and the bolt top then is located the opposite side of vertical shrinkage pool 10, and the nut 32 locking is passed through in the one end of passing vertical shrinkage pool 10 department to make the platform fix on the sighting rod. In some embodiments, the platform 3 is made of steel plate, a connector (not shown) with internal threads is welded on the bottom of the steel plate, and the end of the bolt 31 is inserted into the connector to connect and fix the platform and the bolt.

As shown in fig. 3 and 4, the present invention also provides another structure further comprising an all-weather marine piling construction elevation calibration integrated device, which also comprises a post 1 mounted on the piling hull 100, a measuring scale 2 fixed at the middle upper position of the post 1, except that a support rod 4 vertically fixed on the piling hull 100 is further included, the locator 3 is located at the top of the support rod 4, and the bottom of the support rod 4 and the bottom of the post 1 are located at the same level of the piling hull 100.

The length of the support rod 4 is adjusted by rotating the inner rod 41 relative to the outer tube 42. The outer tube 42 is fixed at the bottom to the pile hull 100 and the retainer 5 is fixed at the top of the inner rod 41 so that as the support bar 4 changes length, the height of the retainer 5 relative to the pile hull 100 also changes. In some embodiments, the inner rod 41 and the outer tube 42 may be rotated up and down by a threaded engagement. The inner rod and the outer tube can also be matched with zero clearance to rotate up and down. In some embodiments, the retainer 5 is secured by gluing it to the top of the inner rod 41.

The utility model provides two all-weather marine piling construction elevation calibration integrated devices, which also comprise an indicating rod 7, wherein one end of the indicating rod is connected to a pile driver drill bit, and the other end of the indicating rod is in contact with a measurement scale. Typically, the post is positioned adjacent to the location of the pile to facilitate viewing of the particular size (scale on the post) required for pile driving. Because of having certain distance between scale and the stake, there is visual error when the construction night very much, for the observer who better makes distant place or night observes correct scale value, set up the pilot lever, this pilot lever direct bit is in the scale department of measuring the scale, and the more audio-visual scale value of pointing out. In some embodiments, the indicator rod is a bent type structure, and in particular, the indicator rod is a "bent" type bent, wherein the vertical section is shorter for connecting the pile driver bit, and the horizontal section is longer for extending horizontally from the pile driver bit to the scale mark.

In the two all-weather marine piling construction elevation calibration integrated devices provided by the utility model, the positioner is GNSS or GPS. GNSS and GPS are all commercially available products, such as midsea rtk 2.

In the two all-weather marine piling construction elevation calibration integrated devices provided by the utility model, the marker post 1 is of a steel pipe structure, and the bottom of the marker post is welded on the piling hull 100. The measuring staff is made of soft materials and is conveniently fixed on the marker post. Such as cloth, soft plastic, soft film, etc., and more specifically, the measuring scale 2 is made of reflective sticker. And sticking the reflective sticker on the marker post. The scale value of the measuring scale fixed on the marker post is gradually increased from top to bottom, and as shown in fig. 1 and 3, the scale mark 21 at the uppermost part is the scale mark of the starting point of the measuring scale, which is usually 0 meter; the scale line 22 at the lowest part is the end scale line of the measuring scale, and the value of the end scale line 22 of the measuring scale is set according to the maximum tide level elevation, such as 5 meters, 6 meters, 7 meters and so on. The scale units are centimeters.

When the piling device is used, when the piling ship body works in a 6.5m pile top designed elevation area, the reflective scale is pasted at a position 6.5m upwards from the bottom of the mark post, and the 0 scale mark of the scale is pasted at the position 6.5m high of the mark post. The height of the supporting rod or the platform from the surface of the piling ship body is 0.5m, the height of the surface of the piling ship body is measured by the GNSS (global navigation satellite system) positioned on the supporting rod or the platform, the height of the input rod is 0.5m on a control display which is positioned in an operation room and connected with the GNSS, and the height displayed by the display is the height of the surface of the ship body. If the display value is 1.29m, measuring the 1.29m scale on the scale, namely the design elevation, controlling the operation arm 15 through the operation room to control the hydraulic rod 11 and the pile driver bit 12 to pile the concrete pipe pile 13, pressing the concrete pipe pile 13 into the mud flat 200, and in the process, moving the horizontal section of the indicating rod 7 fixed on the pile driver bit 12 on the scale 2 from top to bottom along with the downward pressing of the pile driver bit 12 on the concrete pipe pile 13 until the horizontal section of the indicating rod 7 reaches the 1.29m scale mark, stopping the pile driving.

When the piling hull moves from the design elevation area of 6.5m to the design elevation area of 7.0m, since the measuring scale is fixed on the ship, the position of the adjusting platform or the supporting rod relative to the surface of the piling hull is 1.0m, the GNSS on the supporting rod or the platform still displays the elevation of the surface of the piling hull, and thus the scale value on the measuring scale is still the design elevation.
