Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring, in particular to a pile foundation underwater concrete pouring height measuring device. Background Art

[0002] During the construction process, the concrete of the cast-in-place pile foundation usually needs to be poured 0.5-1.0 meters beyond the expected height, and then the excess part is removed. Although this practice can ensure the effective length of the pile foundation, if the excess height is too much, it will not only lead to material waste, but also increase the labor and machinery costs of removing the excess part later. On the contrary, if the pouring height is insufficient, it may endanger the safety and durability of the upper building structure. Therefore, in order to ensure the effective length of the pile body, it is crucial to measure the actual pouring height after the construction of the underwater concrete cast-in-place pile is completed. Traditional measurement methods have many problems, such as low accuracy, complex operation, susceptibility to environmental factors, and high cost. In view of this, a measuring tool is needed to accurately, simply and economically determine the pouring height of underwater concrete to meet the needs of engineering practice.

[0013] The following will be combined with the drawings in the practical embodiment to clearly and completely describe the technical solution in the practical embodiment. Obviously, the described embodiment is only a part of the embodiment of the practical embodiment, not all of the embodiments. Based on the embodiment in the practical embodiment, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this practical embodiment.

[0014] See also Figure 1 The utility model provides a technical solution: a pile foundation underwater concrete pouring height measuring device, comprising:

[0015] In this implementation scheme: firstly, a suitable metal material is selected, and a streamlined end is made by mechanical processing. A buckle is designed at the front end of the end, an externally extended hinge is welded at the middle waist of the end, and a metal ring is vertically welded at the tail of the end; a thin plastic is selected to cut a ring as a float according to the size of the end, and the inner circumference of the ring is equal to the circumference of the hinge. Holes are punched in sequence at the edge of the inner circumference corresponding to the position of the hinge, and the ring is connected to the externally extended hinge; the traction rope is connected to the ring at the tail of the end, and the end falls freely into the mud water body of the cast-in-place pile through the traction rope. The float is automatically unfolded upward by the upward buoyancy of the water body, which plays a role in preventing the steel cage from being stuck during the falling process, and ensures that it reaches the poured concrete surface smoothly. By observing the scale on the traction rope, the construction personnel can accurately judge the pouring height of the concrete. The hollow one-way plate groove at the head of the end collects the coarse and fine aggregates of the concrete. When the device rises after the measurement, the conical float is automatically adjusted to unfold downward by the downward pressure of the water body, reducing the disturbance of the water body to the collected aggregates and ensuring the rising stability of the device. After the measurement is completed, the collected aggregate is poured out of the groove for further processing or use. The hollow one-way slab is cleaned and maintained regularly to ensure its long-term and effective operation.

[0016] Specifically, the hollow one-way plate groove has a specification of 20-25 mm, which is used to collect aggregate and pour it out after the measurement is completed.

[0017] In this embodiment: an aluminum plate of suitable thickness is selected for hollowing design, and a hollow plate with a groove of a specified specification of 20-25mm is produced by mechanical stamping. After production, it is installed on the head of the end and fixed by a buckle.

[0018] Specifically, the end head is made of high-strength, corrosion-resistant metal material to facilitate the recycling of the device; the soft plastic material of the float has good compression resistance and resilience, ensuring that the device can still return to its original state when squeezed by external force to avoid damage; the material of the traction rope is wear-resistant material, which can keep the scale clear and readable during long-term use.

[0019] In this embodiment: the entire end is made of steel material, the buoy material is soft plastic, and the traction rope is made of wear-resistant nylon material.

[0020] Specifically, the connection between the hinge extending outward from the end and the buoy is detachable, so that the buoy with a suitable length can be replaced according to different measuring depths.

[0021] In this embodiment: the externally extended hinge at the waist of the end and the buoy connection are detachable, which is convenient for replacing buoys of different specifications to suit different scenarios.
