Description

Technical Field

[0003] Existing tools for measuring the height of underwater concrete pouring are quite complex to use. Construction workers find it difficult to operate these complex measuring tools, and the cost of using them is also high. Therefore, they require professional technicians and equipment. Measuring the height of underwater concrete pouring under limited conditions is very troublesome, and improper operation can easily lead to large deviations in the measurement of the concrete height.

[0004] According to announcement number CN221681920U, an underwater concrete pouring height measuring device includes a lifting controller, a detection module, and a fixing plate that secures the lifting controller to the outside of the cast-in-place pile casing. The lifting controller is connected to the detection module via a connecting line, controlling the lifting and lowering of the detection module. The fixing plate is fixedly installed at the lower end of the lifting controller, and a fixed pulley is installed on the outside of the fixing plate. The connecting line passes through the fixed pulley and enters the inside of the casing from the overflow port, adhering tightly to the casing wall. The advantages of this invention are: it can collect monitoring data in real time, and this process is unaffected by the complexity of the reinforcing steel. This is because the device is designed to work in various complex environments, including those with a large amount of reinforcing steel. Regardless of the layout or quantity of the reinforcing steel, the device can accurately measure the density and position of the concrete.

Measuring the height of underwater concrete pouring is very troublesome under limited conditions, and improper operation can easily lead to large deviations in the measurement of concrete height. In order to solve the problems mentioned above, an improved tool for measuring the height of underwater concrete pouring is proposed. Utility Model Content

All parts work together to give the measuring tool a complete structure for measuring the height of underwater concrete pouring.

[0024] Note: The height of steel column 2 and clamping assembly 4 is set according to the actual situation. When measuring the height of underwater concrete pouring, the measured value on the surface of measuring rope 5 is added to the height of steel column 2 and clamping assembly 4.

[0025] The base 1 is made of stainless steel mesh with a mesh diameter of 0.5cm. The cross-sectional area of ​​the base 1 is circular, and the diameter of the base 1 is between 6-8cm. The stainless steel material is corrosion resistant and extends the service life. The mesh design is permeable to water, reducing the impact of water flow on the measurement. The appropriate size makes it easy to carry and operate, improving the practicality of the tool.

[0026] The fastening mechanism 3 includes positioning bolts 31, which are circumferentially distributed at the center of the surface of the chassis 1. A connector 32 is welded to the bottom end of the steel column 2. Positioning holes 33 corresponding to the positioning bolts 31 are opened around the surface of the connector 32. The upper end of the positioning bolts 31 passes through the positioning holes 33 and is threadedly connected to a nut 34. The positioning bolts 31 are circumferentially distributed at the center of the chassis 1. The positioning holes 33 of the connector 32 at the bottom end of the steel column 2 correspond to the positioning bolts 31 and are fixed by the nut 34. This facilitates assembly and adjustment by on-site construction personnel, improves construction convenience, and ensures a stable connection.

[0027] The snap-fit ​​assembly 4 includes a bent rod 41, with its two U-shaped ends fixed to the top of the steel column 2. A connection port 42 is formed between the bent rod 41 and the steel column 2. A buckle 43 is snapped into the connection port 42. One end of the measuring rope 5 is installed on the buckle 43. The connection port 42 is formed by the bent rod 41 and the buckle 43 snaps into the connection port 42. The measuring rope 5 is connected to the buckle 43. The installation method is simple and quick, which facilitates the installation and replacement of the measuring rope 5, improves the flexibility of use, and makes the measurement operation more convenient.

[0028] The counterweight mechanism 6 includes a steel plate 61 with through holes 62 around its surface. A connecting rod 63 is inserted into the inner cavity of the through holes 62. A counterweight block 64 is welded to the lower end of the connecting rod 63. The connecting rod 63 includes a rod body 631 with an integrally formed thread 632 at its upper end. A limit sleeve 633 is threadedly connected to the surface of the rod body 631 at the position of the thread 632.

[0030] In practical use, the steel column 2 is first securely fixed to the center of the chassis 1 using the fastening mechanism 3. Specifically, the positioning bolts 31, which are circumferentially distributed at the center of the chassis 1, are matched with the corresponding positioning holes 33 on the bottom connector 32 of the steel column 2, and then tightened with nuts 34 to ensure a firm connection and facilitate on-site assembly and adjustment. The snap-fit ​​assembly 4 at the top of the steel column 2 is used to install the measuring rope 5. The U-shaped bent rod 41 is fixed to the top of the steel column 2 to form a connection port 42, into which the buckle 43 is inserted. One end of the measuring rope 5 is connected to the buckle 43, which facilitates the quick and easy installation and replacement of the measuring rope 5. During measurement, the height of the steel column 2 and the snap-fit ​​assembly 4 are determined according to the actual situation. The measurement value on the surface of the measuring rope 5 is related to these two heights. The height of the underwater concrete pouring is calculated by summing the heights of the measurements. The counterweight mechanism 6 provides stability for the measurement. The connecting rod 63 is inserted into the through hole 62 on the steel plate 61. The counterweight block 64 is welded to the lower end of the connecting rod 63. The counterweight can be adjusted by rotating the position of the limiting sleeve 633 on the thread 632 of the rod body 631 to adapt to different water flow and measurement environments. The chassis 1 uses a circular stainless steel mesh with a diameter of 6-8cm and a mesh diameter of 0.5cm. It is permeable to water while reducing the impact of water flow and is easy to carry and operate. The edges of the chassis 1 are bent inward and there are ring-shaped reinforcing ribs 7 on the inner side, which enhances the resistance to deformation, reduces the risk of collision damage, ensures that the entire measuring tool can work stably, and facilitates operation by construction personnel.

[0031] Measurement principle: After the volume of underwater concrete reaches the design volume, a measuring rope is slowly lowered into the water. Based on the change in resistance, it is determined whether the concrete pouring position has been reached. The elevation of the underwater concrete is determined according to the scale on the measuring rope. The concrete is then slowly raised to the surface, and the presence of coarse aggregate residue on the bottom stainless steel mesh is observed to further determine whether the concrete pouring position has been reached, so as to more clearly determine whether the concrete pouring height meets the requirements.
