Problems solved by technology

In the past, wooden wedges were used to block such cases, but the wooden wedges would swell after being soaked in water, making it impossible to pull them out from the water inlet hole. ", this process is cumbersome, wastes time, and has a certain impact on the construction quality
The main body of the current expansion plug is made of polyethylene, which will not cause expansion and cannot be disassembled, so that the blind plate is still used for water pressure during the installation and construction of the caisson.

Embodiment 1

[0019] Such as figure 1 As shown, the expansion plug is easy to install and disassemble. The cylindrical expansion plug body 1 is perforated inside. The front end of the hole is an inverted tapered opening matching the size of the inverted tapered plug body 4. The screw 2 is inserted through the expansion plug body 1. , the front section of the lead screw 2 is installed with an inverted tapered plug body 4, the rear part of the expansion plug body 1 is connected to a baffle plate 6 whose diameter is larger than that of the expansion plug body 1, the inverted tapered plug body 4 and the baffle plate 6 are connected through the lead screw 2, and the expansion The rear end of the plug body 1 is connected with a compass 7 with a bayonet, and the rear end of the lead screw 2 passes through the compass 7 .

[0020] A groove is provided on the main body 1 of the expansion plug, and a water-stop rubber ring 5 is sleeved in the groove.

[0021] The water-stop rubber rings 5 ​​are in f...

Embodiment 2

[0026] The application of the expansion plug convenient for installation and disassembly described in Example 1, the expansion plug is applied to the plugging of underwater holes, and the specific application method includes the following steps:

[0027] S1. After processing various materials, assemble them. When sealing the hole, insert the front end of the expansion plug into the hole, such as figure 2 As shown, use a round steel 8 with a length of 30 cm and a diameter of 1.5 cm, clamp it at the bayonet of the compass 7, rotate it clockwise, and tighten the screw 2, so that the inverted tapered plug body 4 faces the expansion plug body 1 hole Move inside to expand the diameter of the rear section of the main body 1 of the expansion plug to achieve the purpose of sealing; at the same time, the components can be processed and manufactured according to the size of the hole, so as to be suitable for the sealing of holes of different sizes;

[0028] S2. When removing the expansi...

Abstract

The invention relates to the technical field of underwater construction, in particular to an expansion plug convenient to install and dismantle and application. A hole runs through a cylindrical expansion plug main body, the front end of the hole is provided with an inversely conical opening matched with an inversely conical plug body in size, a lead screw is inserted into and penetrates through the expansion plug main body, the inversely conical plug body is mounted at the front segment of the lead screw, the rear portion of of the expansion plug main body is connected with a baffle the diameter of which is greater than that of the expansion plug main body, the inversely conical plug body is connected to the baffle through the lead screw, the rear end of the expansion plug main body is connected with a compass with a clamping opening, and the rear end of the lead screw penetrates through the compass. The expansion plug can be applied to the situation that holes cannot be sealed by conventional processes when the underwater construction operation is limited; at the same time, the application can be adopted for effectively solving the situation that the holes are needed to be reusedfor the construction work after treatment, the water sealing effect is good, the capability of resisting water pressure is great, and the expansion plug is very easy to dismantle.

Description

technical field [0001] The invention relates to the technical field of underwater construction, in particular to an expansion plug convenient for installation and disassembly and its application. Background technique [0002] During the construction of this project, due to the influence of wind and waves, some of the blind plates of the caisson have been covered by sea mud, resulting in the blind plate of the caisson cannot be used normally, so it is necessary to seal the water inlet hole of the caisson inside the cabin. In the past, wooden wedges were used to block such cases, but the wooden wedges would swell after being soaked in water, making it impossible to pull them out from the water inlet hole. ", this process is cumbersome, wastes time, and has a certain impact on the construction quality. However, the main body of the current expansion plug is made of polyethylene, which will not cause expansion and cannot be disassembled, so that the blind plate is still used fo...
