Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete pouring technology, and in particular to a concrete pouring height measuring device. Background Technology
[0002] In construction projects, pile foundations are frequently used when the bearing capacity of the foundation soil is insufficient. To facilitate movement of the pile driving area and accelerate construction progress, piles are typically driven into the existing ground. However, in this case, the ground elevation is higher than the designed pile top elevation, resulting in significant drilling dead zones. Furthermore, the presence of water or mud in the pile holes makes it impossible to visually monitor the concrete pouring height during pouring, leading to two extremes: either insufficient concrete pouring height, failing to guarantee the effective pile length and affecting project quality; or excessive over-pouring of concrete at the pile top, resulting in significant concrete waste, increasing the workload of later pile head trimming, and raising construction costs. Therefore, to strengthen pile quality control and reduce material waste, a precise concrete pouring height measuring device is necessary.
[0003] Traditionally, the concrete pouring surface measurement of piles is measured using a manual probing method. The procedure involves a person holding a probing rod and inserting it into the pile hole, relying on their experience to gauge the material density within the hole. When the probing rod becomes difficult to insert, it is assumed to have reached the concrete interior, and the pouring height is then calculated. This method relies on the operator's experience and cannot achieve accurate identification. Utility Model Content

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] In related technologies, the traditional method for measuring the concrete pouring surface of piles uses a manual probing method. The specific operation involves a person holding a probing rod and inserting it into the pile hole, relying on their experience to gauge the material density inside the hole. When the probing rod becomes difficult to insert, it is assumed that the rod has reached the interior of the concrete, and the pouring height of the concrete surface is then calculated. This method relies on the operator's experience and cannot achieve accurate identification.
[0024] In view of this, such as Figure 1 and Figure 2 As shown, some embodiments of this utility model provide a concrete 7 pouring height measuring device, including a pressure detection unit 4, a receiving unit 1, and a pile main reinforcement 5; the pressure detection unit 4 is connected to the pouring height of the pile main reinforcement 5, the pile main reinforcement 5 is set in the pile hole 8, and the pressure detection unit 4 is used to detect the height of the concrete 7; the pressure detection unit 4 is electrically connected to the receiving unit 1, the receiving unit 1 is set on the ground 3, and the pressure detection unit 4 is used to transmit the electrical signal to the receiving unit 1.
[0025] In the above embodiment, the pressure detection unit 4 can be configured as a piezoresistor. The pressure detection unit 4 can be fixed on the main reinforcement 5 of the pile body. The pressure detection unit 4 can be connected to the main reinforcement 5 of the pile body by means of bolts, welding or wire binding. The main reinforcement 5 of the pile body can be made of threaded steel. The main reinforcement 5 of the pile body extends into the pile hole 8. The pile hole 8 can be cylindrical. The length direction of the main reinforcement 5 of the pile body can be parallel to the axis of the pile hole 8. After the main reinforcement 5 of the pile body extends into the pile hole 8, the height of the concrete 7 is marked on the main reinforcement 5. The pressure detection unit 4 is fixed on the main reinforcement 5 of the pile body and is located at the height of the concrete 7 being poured. The pile hole 8 is surrounded by pile perimeter soil 9.
[0026] The implementation steps are as follows:
[0027] Step 1: Fix the pressure testing unit 4 to the main reinforcement bar 5 of the pile body using adhesive 10.
[0028] Step 2: Connect the pressure detection unit 4 via connecting wire 2 to ensure that the value of the pressure-sensitive resistor can be measured.
[0029] Step 3: After the main reinforcement bars 5 and stirrups 6 of the pile body are connected together, the connected main reinforcement bars 5 and stirrups 6 are inserted into the pile hole 8 and positioned. Then, the pressure detection unit 4 is connected to the receiving unit 1 using the connecting line 2.
[0030] Step 4: Before pouring concrete 7, the original value of the pressure detection unit 4 is measured by the receiving unit 1.
[0031] Step 5: During the pouring process, the pressure detection unit 4 is measured in real time. When the concrete 7 reaches the pouring elevation, the resistance value measured by the receiving unit 1 will change abruptly. At this time, the pouring of concrete 7 will be stopped.
[0032] This utility model provides a concrete pouring height measuring device, comprising a pressure detection unit 4, a receiving unit 1, and a main reinforcement bar 5 of the pile body. The pressure detection unit 4 is connected to the pouring height of the main reinforcement bar 5, which is installed inside the pile hole 8. The pressure detection unit 4 is used to detect the height of the concrete 7. The pressure detection unit 4 is electrically connected to the receiving unit 1, which is installed on the ground 3. The pressure detection unit 4 is used to transmit the electrical signal to the receiving unit 1. This solves the technical problem of inaccurate identification of the concrete 7 height in the prior art, achieving the technical effect of accurate concrete 7 height identification.
[0033] In an optional embodiment, an adhesive 10 is provided between the pressure detection unit 4 and the main reinforcement 5 of the pile body, and the pressure detection unit 4 is connected to the main reinforcement 5 of the pile body through the adhesive 10. A connecting line 2 is provided between the pressure detection unit 4 and the receiving unit 1, and the two ends of the connecting line 2 are respectively connected to the pressure detection unit 4 and the receiving unit 1 for electrical signals. Multiple main reinforcements 5 of the pile body are provided, and the multiple main reinforcements 5 of the pile body are evenly arranged in the pile hole 8.
[0034] In an optional embodiment, it also includes stirrups 6, which are connected to a plurality of main pile reinforcement bars 5. The stirrups 6 are wound around the plurality of main pile reinforcement bars 5 along the length direction of the main pile reinforcement bars 5. Multiple pressure detection units 4 are provided, which are spaced apart along the diameter direction of the pile hole 8. Each pressure detection unit 4 is electrically connected to a detection unit. The multiple pressure detection units 4 are arranged close to each other. The length of the multiple main pile reinforcement bars 5 is the same. The end faces of the multiple main pile reinforcement bars 5 are arranged on the same plane. The main pile reinforcement bars 5 are spaced apart from the inner wall of the pile hole 8.
[0035] By measuring the resistance value of the pressure detection unit 4 under different media, it is determined whether the varistor is in the concrete 7, and thus whether the surface of the concrete 7 has reached the designed height. The monitoring of whether the concrete 7 has reached the pouring height can be done intuitively through numerical values. The entire process only requires one varistor and a small number of connecting wires 2. The receiving unit 1 can use a resistance measuring instrument, which is reusable and has a lower cost.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
