Abstract
Description
Technical Field
[0001] This utility model relates to the field of grouting equipment technology, and in particular to a construction device for underwater grouting construction. Background Technology
[0002] During bridge construction, it is necessary to reinforce the bottom of the pile foundation in the water by pouring concrete. During this process, baffles need to be built around the bottom of the pile foundation. After steel bars are installed inside, grouting is used to fill the inside of the baffles. During grouting, grouting pipes are used to penetrate from above the water to the bottom. As grouting progresses, the grouting pipes are gradually raised to ensure the smooth completion of grouting. At present, after the grouting pipes are penetrated, it is difficult to move them horizontally, making it difficult to achieve uniform grouting. Manual leveling is required, which affects the quality of the finished product. Summary of the Invention
[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a construction device for underwater grouting construction that is simple in structure, stable in operation, and highly automated.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A construction device for underwater grouting includes at least two grouting frames and mounting bases. A lateral moving structure is installed on the grouting frame. The lateral moving structure is used to drive a lifting structure to move. The lifting structure is used to drive a pipe clamp to move in the vertical direction. The pipe clamp is used to hold the grouting pipe. A grouting pipe guide structure is also installed on the grouting frame.
[0006] In this construction process, firstly, baffles are erected around the bottom of the pile foundation in the water, with steel reinforcement installed inside. Then, grouting frames are erected underwater. The number of grouting frames is selected according to need, generally four, one for each of the four sides of the pile foundation bottom. After erection, the grouting pipe passes through the grouting pipe guide structure and is clamped by pipe clamps. The grouting pipe is connected to grouting equipment. During grouting, a lateral moving structure moves the grouting pipe laterally. After a certain grouting time, a lifting structure raises the grouting pipe to a certain height, and the lateral moving structure continues to move the grouting pipe laterally until grouting is complete. The entire grouting process only requires initial setup; manual supervision is possible later, and the whole process can be automated.
[0007] The grouting frame includes three columns arranged in a triangle. One column is fixedly connected to the columns on both sides of it by several spaced connecting rods. The columns on both sides are fixedly connected by several spaced sliding rods. The sliding rods and connecting rods are staggered. An installation base is fixedly installed on the upper end of the column.
[0008] The lower end of the column is fixed with a base plate, and the base plate has mounting holes.
[0009] The lateral movement structure includes a one-way screw, and two supports are fixedly installed on the mounting base. The one-way screw is connected to the supports through bearings.

The nut block is fixedly installed on a limiting seat, and the limiting seat slides against the mounting base.
[0010] The lifting structure includes a lifting seat, on which a lifting cylinder is fixedly installed. The cylinder rod of the lifting cylinder passes through the lifting seat and is fixedly connected to a limiting seat. Two guide rods are fixedly installed on the limiting seat. The lifting seat has guide holes that slide with the guide rods. The pipe clamp is installed at one end of the lifting seat.

In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0017] like Figure 1-3 As shown, a construction device for underwater grouting includes at least two grouting frames and mounting bases. A lateral moving structure is installed on the grouting frame. The lateral moving structure is used to drive a lifting structure to move. The lifting structure is used to drive a pipe clamp 1 to move in the vertical direction. The pipe clamp is used to hold the grouting pipe. A grouting pipe guide structure is also installed on the grouting frame.
[0018] In this construction process, firstly, baffles are erected around the bottom of the pile foundation in the water, with steel reinforcement installed inside. Then, grouting frames are erected underwater. The number of grouting frames is selected according to need, generally four, one for each of the four sides of the pile foundation bottom. After erection, the grouting pipe passes through the grouting pipe guide structure and is clamped by pipe clamps. The grouting pipe is connected to grouting equipment. During grouting, a lateral moving structure moves the grouting pipe laterally. After a certain grouting time, a lifting structure raises the grouting pipe to a certain height, and the lateral moving structure continues to move the grouting pipe laterally until grouting is complete. The entire grouting process only requires initial setup; manual supervision is possible later, and the whole process can be automated.
[0019] During the grouting process, the diameter of the grouting pipe is fixed, and the amount of grout injected over a certain period of time is basically determined. The grouting time can be adjusted according to the amount of grout injected at the bottom of the pile foundation, thereby adjusting the movement of the lateral moving structure and the lifting structure.
[0020] In practice, the grouting frame includes three columns 2 arranged in a triangle. One column is fixedly connected to the columns on both sides of it by several spaced connecting rods 3. The columns on both sides are fixedly connected by several spaced sliding rods 4. The sliding rods and connecting rods are staggered. An mounting base 41 is fixedly installed on the upper end of the column.
[0021] In this way, the triangle provides stability. The three pillars, connecting rods, and sliding rods form a triangular prism structure, resulting in high stability. The mounting base is located above the water surface.
[0022] During implementation, a base plate 5 is fixed to the lower end of the column, and the base plate has mounting holes. The grouting frame is stabilized by ground anchors to improve stability.
[0023] In implementation, the lateral movement structure includes a one-way screw 6, two supports 7 are fixedly installed on the mounting base, the one-way screw is connected to the supports through bearings, a servo motor 8 is fixedly installed on one of the supports, one end of the one-way screw is fixedly connected to the output shaft of the servo motor, a nut block is threaded onto the one-way screw, the nut block is fixedly installed on the limiting seat 9, and the limiting seat slides against the mounting base.
[0024] In this way, the servo motor drives the unidirectional screw to rotate, which in turn drives the limit seat to move through the nut block, thereby driving the lifting structure to move.
[0025] In implementation, the lifting structure includes a lifting seat 10, on which a lifting cylinder 11 is fixedly installed. The cylinder rod of the lifting cylinder passes through the lifting seat and is fixedly connected to a limiting seat. Two guide rods 12 are fixedly installed on the limiting seat. The lifting seat has guide holes that slide with the guide rods. The pipe clamp is installed at one end of the lifting seat. The pipe clamp is an existing structure used to clamp the grouting pipe.
[0026] In this way, the piston rod of the lifting cylinder moves, causing the lifting seat to move relative to the limit seat, and the guide rod can guide the movement of the lifting seat.
[0027] In implementation, the grouting pipe guide structure includes a sliding sleeve 13 that slides on the sliding rod, adjacent sliding sleeves are fixedly connected by adjacent rods 14, a guide sleeve 15 is fixedly connected to the sliding sleeve, the guide sleeve and the pipe clamp are arranged facing each other in the vertical direction, a transmission rod 16 is fixedly installed downward on the limiting seat, the lower end of the transmission rod is fixedly connected to the uppermost sliding sleeve, and a groove 17 is provided on the mounting seat that slides with the transmission rod.
[0028] In this way, by setting up the guide sleeve, the grouting pipe passes through the guide sleeve. When the lateral moving structure moves, the grouting pipe is driven to move by the pipe clamp. The guide sleeve can guide the grouting pipe, making the movement of the grouting pipe more stable and reliable. The guide sleeve can slide along the sliding rod, which facilitates installation.
[0029] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
