Problems solved by technology

[0002] The base of the existing underwater system is generally a trapezoidal base. In order to ensure the stability of the underwater base and reduce the influence of seabed rapids and geological changes, the contact area between the base and the seabed is required to be large, so the volume of the base is large. , heavy weight, generally large construction ships are used for underwater hoisting construction, the equipment required for construction is complicated, the time is long, and the cost is high
At the same time, the existing base has poor adsorption capacity, lacks the function of easy recycling, and needs to adjust the posture of the base, which is more difficult, time-consuming and labor-intensive

Embodiment 1

[0030] Embodiment 1: as Figure 1 to Figure 6As shown, a seabed adsorption base that is easy to recycle includes a base body 1 and an underwater device 2 installed on the base body 1. The base body 1 is a plate structure, and is installed along the base body 1 bottom. The adsorption cavity 3 extending downwards, the adsorption cavity 3 includes a cavity wall 4 distributed along the bottom edge of the base body 1, the middle part surrounded by the cavity wall 4 forms an adsorption cavity 5, and the base body 1 is pressed There are at least four channel pipes 6 connected to the adsorption chamber 5 in four directions, and a discharge pipe 13 opened on the base body 1 and connected to the adsorption chamber. The discharge pipe 13 has a movable valve cap, and the passage pipe 6 is equipped with a detachable or elastic adjustable valve cover. The base body 1 is a square plate structure with a size of about 3000mm (length) × 3000mm (width) × 800mm (height), or the base body 1 is a ...

Embodiment 2

[0036] Embodiment 2: The adsorption and recovery method of the seabed adsorption type base recorded in a kind of embodiment 1, such as Figure 7 , Figure 8 shown, including the following steps:

[0037] S1. Lift the main body 1 of the base to the predetermined position on the bottom seabed; after the base is processed, connect the lifting structure on the main body 1 of the base through the hook of the surface ship sling and lift it into the water until it reaches the predetermined position ;

[0038] S2. Open the bonnet of the discharge pipe 13, connect the bonnet of the passage pipe 6 with the external device, inject high-pressure water into the adsorption chamber 5 through the passage pipe 6, and blow up the seabed silt inside and below the adsorption chamber 5, And get rid of from the discharge pipe 13, close the valve cap, stop injecting high-pressure water, and the adsorption cavity 3 is stably adsorbed on the seabed surface;

[0039] S3. When recovering the base, in...

Abstract

The invention provides a seabed adsorption type base convenient for recovery and an adsorption and recovery method thereof. The seabed adsorption type base comprises a base main body and underwater equipment arranged on the base main body, wherein the base main body is of a plate-type structure, and an adsorption type cavity extending downwards is arranged along the bottom of the base main body; the adsorption type cavity comprises cavity walls distributed along the edge of the bottom of the base main body; an adsorption cavity is formed in the middle part surrounded by the cavity walls; at least four channel pipes communicated with the adsorption cavity are arranged on the base main body in four directions; a detachable or elastic adjustable one-way valve cover is arranged on the channelpipes. According to the invention, under the condition of reducing the weight and the volume of the base, the structure of the base is changed, so that the base has the cascade characteristic, and theconstruction is convenient, and the stability of the seabed of the base can be enhanced. The base has the characteristics of light weight and easy construction, and has the functions of seabed adsorption, posture adjustment and recovery, can be suitable for different seabed environments, and is beneficial to reducing the offshore construction cost and the construction time.

Description

technical field [0001] The invention relates to the technical field of an underwater base, which is used for fixing the base by absorbing it on the seabed, in particular to a seabed adsorption type base which is convenient for recovery and an adsorption and recovery method thereof. Background technique [0002] The base of the existing underwater system is generally a trapezoidal base. In order to ensure the stability of the underwater base and reduce the influence of seabed rapids and geological changes, the contact area between the base and the seabed is required to be large, so the volume of the base is large. , heavy weight, generally adopt large-scale construction ship to carry out underwater lifting construction, the equipment required for construction is complicated, time is long, and cost is high. At the same time, the existing pedestal has poor adsorption capacity, lacks the function of being convenient for recycling, and needs to adjust the posture of the pedestal,...
