Description
TECHNICAL FIELD
[0001] The utility model relates to bridge construction technical field especially relates to a steel mixes combination ship anchor. BACKGROUND
[0002] In the process of building a cross-sea bridge, large ship equipment is often used to meet the needs of various types of construction, and various ships need to be fixed after anchoring to carry out normal construction. However, for the sea area with coral reef limestone on the seabed surface, there are large-volume, hard-textured exposed plate-shaped reef limestone, and the terrain is uneven. The traditional holding power anchor currently used is inserted into the inside of the seabed mud bed or sand bed to ensure effective grip and limit the movement of the ship, but for the sea area with coral reef on the bottom, the traditional holding power anchor cannot penetrate the reef limestone to ensure sufficient grip, which will cause the anchor to move. As a result, not only can normal construction work be ensured, but also the safety hazards of ship collision and other problems are increased. At the same time, if the holding power anchor is stuck in the stone gap, the ship cannot sail, and the anchor chain may need to be cut off to ensure the normal operation of the ship body, which will cause great economic loss.
[0003] Relatedly, to ensure the stability of the ship, the heavier the ship, the heavier the gravity anchor it needs, and the higher the cost. To ensure the smooth deployment and anchoring of the gravity anchor, the cost of the corresponding auxiliary equipment is also higher. At the same time, when using a gravity anchor with too much weight, if the falling speed of the anchor chain is too fast, it may also cause the anchor chain to be lost due to the anchor machine's inability to brake in time, or the anchor to deform or be damaged due to excessive pressure when the gravity anchor touches the bottom. Therefore, how to make the gravity anchor suitable for ship operations in coral reef seabed areas with low cost and high stability is a problem that needs to be solved by personnel in the field.

[0035] Specifically, the steel-concrete combined ship anchor in the embodiment adopts a form of combination of a steel casing 10 and concrete 20 to serve as a ship anchor, so as to ensure that the weight of the ship anchor meets the requirements, and also to greatly reduce the manufacturing cost of the ship anchor, and the weight of the ship anchor can be adjusted according to the needs of the site.

Alternatively, the outer side of the steel casing 10 is also provided with lifting lug assemblies 40 for hoisting, so that the lifting lug assemblies 40 can be used for hoisting during anchoring and anchoring, to avoid damage to the steel-concrete combined ship anchor due to the too fast falling speed of the anchor chain, and the steel-concrete combined ship anchor can also be timely retrieved through the lifting lug assemblies 40 according to the site conditions, so as to ensure the stability of the anchoring of the steel-concrete combined ship anchor while reducing the operation cost.
[0036] The specific structure of the steel-concrete combined ship anchor in the embodiment will be described below.
[0037] As shown in Figure 1 , the steel-concrete combined ship anchor in the embodiment includes a steel casing 10, embedding assemblies 30 and lifting lug assemblies 40, and the inside of the steel casing 10 is poured with concrete 20. Specifically, the steel-concrete combined ship anchor in the embodiment is mainly suitable for anchoring operation of the ship body at the coral reef seabed, so as to avoid the problems of walking, deformation or damage of the gravity anchor used in the prior art. As shown in Figure 2 and Figure 3 , the steel casing 10 in the embodiment is made of steel plate rolling, and the steel casing 10 is wrapped on the surface of the concrete 20, and the two form an integral body, which can meet the gravity effect of the ship anchor and ensure the normal use of the anchoring operation.

Further, the curvature of the first arc edge 321 on the support plate 32 matches the curvature of the outside of the steel casing 10, and the first arc edge 321 is arranged in abutment with the outside of the steel casing 10, so as to ensure the stable installation of the embedded fixing assembly 30 on the outside of the steel casing 10. Optionally, the support plate 32 can be fixed on the outside of the steel casing 10 by welding, so as to avoid the falling off of the embedded fixing assembly 30 during the anchoring and fixing process. Further, the right-angled edges of the bracket steel plates 31 are also welded on the outside of the steel casing 10, so as to improve the overall mechanical strength of the embedded fixing assembly 30 and ensure stable anchoring.

Illustratively, the included angle between the positions where the two lifting lug assemblies 40 in each group of lifting lug assemblies 40 are arranged on the outside of the steel casing 10 is 90°, so that the stability of the hoisting process can be ensured when the steel-concrete combined ship anchor is hoisted by the lifting lug assemblies 40.
