Description

TECHNICAL FIELD

[0001] The utility model relates to underwater steel pipe pile measurement field, concretely to underwater steel pipe pile distance measuring device. BACKGROUND

[0002] In recent years, domestic offshore wind power technology develops continuously, and the wind turbine becomes larger and larger, so it requires that the wind turbine foundation has high strength, good stability, convenient installation and low cost, and the jacket foundation is the best choice to adapt to this technical requirement. At present, the water depth that the jacket foundation adapts is usually 25m~50m, and the foundation is usually composed of four steel pipe piles and an internal plug type jacket. Most of the jacket foundations adopt the pile first method, that is, the underwater sinking pile construction of the steel pipe pile is carried out first, then the underwater insertion tip section at the bottom of the jacket is inserted into the steel pipe pile one by one, and then grouting is carried out in the gap between the steel pipe pile and the insertion tip, so that the jacket is fixed on the steel pipe pile.

[0003] Usually, the design drawing requires that the relative position of the jacket insertion tip in the steel pipe pile plane has a movable range of only 75mm, so it requires that the underwater construction precision of the steel pipe pile is very high. During the offshore sinking pile operation, the construction precision is affected by the wind, wave, surge, pile delivery device and pile hammer, and if the underwater steel pipe pile completion measurement is not carried out, the jacket installation may not be successfully completed.

[0004] At present, the relative distance measurement of the underwater steel pipe pile of the offshore project usually adopts the following methods: multi-beam measurement method, direct distance measurement method between the center points of the steel pipe piles and the around pile distance measurement method, but these methods have some problems in actual application: taking the multi-beam method as an example, this method can only be carried out by entrusting a qualified unit, and the cost is high, so it is difficult to popularize, for example, the patent application with the patent publication number CN117627069 discloses a underwater measurement method for the steel pipe pile of the jacket foundation by the pile first method; the direct distance measurement method between the center points of the steel pipe piles requires processing a cross tool to find the center points of the steel pipe piles, the tool is heavy, the diver cannot move it during the measurement, and the crane needs to be used, which is very inconvenient; in addition, the around pile distance measurement method needs to wind a steel wire rope around two steel pipe piles, and the relative distance is calculated after the total length is measured, so the underwater operation of this method is very troublesome and not suitable.

[0028] The opposite side of the two positioning assemblies 2 is provided with a positioning ruler 7, and the two positioning rulers 7 are respectively used to align the scale A and the scale B to measure the actual distance between the two steel pipe piles 1.

[0029] Preferably, the diameter of the steel wire measuring rope 5 is 3mm, in order to overcome the influence of the buoyancy and the water flow of the steel wire measuring rope 5 in the water, the weight of the counterweight 6 can be selected as 40kg to 46kg.

[0030] Preferably, the winch 3 is a waterproof winch with underwater working capacity, which is a prior art, so it is not described here.
