Problems solved by technology

If the underwater anchor block adopts this type of structure, because the top of the anchor block structure needs to be at least 1.5m higher than the connection point between the anchor chain and the end shackle, if the anchor block is in the channel area, it is likely to affect the navigation of the ship; Digging deep to reduce the top elevation of the anchor block structure to avoid affecting the navigation of the ship will bring difficulties to the dredging of the foundation trench and increase the construction cost

Embodiment 1

[0021] Example 1: See Figure 1-2 , the present invention provides a technical solution: a steel plate tether ring for the anchor block of the caisson type floating dock, the lower part of the tether ring is buried in the anchor block concrete 8, which includes a main board 1, an additional ear plate 2, Front shear plate 3, rear shear plate 4, upper rib 5, lower rib 6 and reinforcement cage 7;

[0022] The front shear plate 3 and the rear shear plate 4 are parallel to each other, and are respectively vertically welded on the front and rear sides of the main board 1, and the upper sides of the upper part of the main board 1 are respectively welded on one side of the front shear plate 3 and the rear shear plate 4. Reinforcement ribs 5, the lower reinforcement ribs 6 connecting the front shear plate 3 and the rear shear plate 4 are welded on both sides of the lower part of the main board 1; the reinforcement cage 7 is buried in the anchor block concrete 8, and the tether ring is ...

Embodiment 2

[0030] Embodiment 2: The specific assembly steps of the steel plate type tether ring of the present invention are as follows:

[0031] Taking the newly built floating dock with a rated displacement of 85,000 tons as an example, anchoring and mooring is adopted, and a total of 20 anchors are used. Due to the poor protection conditions of the breakwater and the strong wind and waves in the port, a single anchor is subjected to a large force. The maximum is: the horizontal force standard value is 6000kN , the standard value of vertical force is 600kN. The caisson-type anchor block is adopted, and the steel plate tether ring is poured together with the caisson concrete. The tether ring is provided with holes to facilitate connection with the end shackle of the anchor chain. The specific construction steps are as follows:

[0032] S1. Processing of steel plate tie chain ring

[0033] Process the steel plate tether ring according to the tether ring structure drawing, and connect th...

Abstract

The invention belongs to the field of floating dock anchoring, and particularly discloses a steel plate type chain tying ring for a caisson type floating dock anchor block. The steel plate type chain tying ring comprises a main plate, an additional lug plate, a front anti-shearing plate, a rear anti-shearing plate, an upper reinforcing rib plate, a lower reinforcing rib plate and a reinforcement cage. According to the steel plate type chain tying ring for the caisson type floating dock anchor block, external force transmitted by an anchor chain is transmitted to the front anti-shearing plate and the rear anti-shearing plate through the main plate, the anti-shearing plates have a certain width so that the situation that local overstocked stress of concrete and punching-resistant checking calculation of an embedded part meet the requirements can be guaranteed, the beneficial effect of horizontal soil resistance of backfilled stone outside the caisson type anchor block on an anchorage design can be brought into full play, the steel plate type chain tying ring is more economical and does not affect the navigation of a ship, and the chain tying ring is not pulled out or the anchor block concrete is not damaged by punching; and compared with a traditional type of chain tying ring, the chain tying ring for the caisson type floating dock anchor block is suitable for use working conditions which are mainly subjected to horizontal stress and are large in horizontal stress, does not need to consider bolt loosening and corrosion conditions, does not need to be maintained in a trial period, and is particularly suitable for a large floating dock.

Description

technical field [0001] The invention relates to the field of mooring in floating docks, in particular to a steel plate tie chain ring used for anchor blocks in caisson-type floating docks. Background technique [0002] At present, there are generally three structural types for tethering rings for land cattle: [0003] 1) Bend the round steel into a tie ring, and the anchor chain is connected with the tie ring through the end shackle, and the part of the tie ring embedded in the ground beef concrete is connected with the anchor steel plate or the anchor channel steel to ensure that the concrete part will not be crushed, The concrete of the ground cow will not be damaged by punching, and the embedded part of the tether ring will not be pulled out. It can only be used in the working conditions where the force is small and the main force direction is vertically upward. [0004] 2) The steel plate is used as the pull lug, and the anchor chain is connected with the pull lug throu...
