Description

Technical Field

[0001] The invention relates to the technical field of civil engineering, and in particular to a construction control method and device for real-time monitoring of concrete pile top elevation. Background Art

[0002] Bored piles have been widely used in civil engineering due to their unique construction technology. This type of pile foundation forms a bearing pile body by drilling holes in the ground and pouring concrete. It is suitable for various soil conditions and has good adaptability and high bearing capacity. However, in the actual construction process, in order to ensure the density and quality of the concrete on the top of the pile, the over-pouring construction method is usually adopted, that is, pouring more concrete to a certain height during pouring, and then chiseling off the excess part after the concrete reaches the design age and strength requirements.

[0003] However, this traditional over-pouring method has significant disadvantages. Due to the uncertainty of manual and mechanical operations, it is often difficult to accurately control the over-pouring amount of concrete, and excessive over-pouring of concrete is common. This not only leads to waste of concrete materials, but also increases the workload of subsequent chiseling of excess concrete, further increasing the construction cost. Especially when there are a large number of pile foundations, this waste of materials and labor will cause greater economic losses. At the current construction site, the control of the elevation of the top of the concrete over-pouring pile mainly relies on the naked eye observation of workers, and lacks accurate measurement methods. This method has poor accuracy and is limited by the construction environment and workers' experience. There is a large deviation in the control of the elevation. In addition, the timeliness of manual control is poor, and it cannot be monitored and adjusted in real time, resulting in low efficiency of the construction process. Therefore, how to accurately control the elevation of the top of the concrete over-pouring pile, reduce material waste, and reduce construction costs has become an urgent problem to be solved in engineering construction. Summary of the invention

[0004] The purpose of the present invention is to provide a construction control method and device for real-time monitoring of the concrete pile top elevation, so as to solve the problem of how to accurately control the elevation of the concrete over-filled pile top, reduce material waste and reduce construction costs.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1As shown, a construction control method for real-time monitoring of concrete pile top elevation, the method comprising:

[0033] S1: During the bored pile construction process, a borehole casing 1 is first set at the hole mouth to ensure the stability of the soil. The borehole casing can be made of steel to ensure its stability during the construction process;

[0034] S2: After the hole is formed, the steel cage is placed in the hole, and a fixing frame device 2 is installed on the top of the drilling casing 1. An adjustable hydrometer 3 and a floating rod 4 are assembled on the fixing frame device 2. The installation position of the adjustable hydrometer 3 ensures that it can change with the rise of the concrete top surface;

[0035] S3: During the concrete pouring process, when the top surface of the concrete rises to the position of the adjustable hydrometer 3, due to the large specific gravity of the concrete, the adjustable hydrometer 3 is forced to rise, thereby driving the floating rod 4 to rise;

[0036] S4: A scale 5 is set on the side of the floating rod 4. When the top surface of the concrete reaches the designed height, the floating rod 4 rises to the top of the scale 5, triggering the alarm 6 on the top of the scale 5. The alarm 6 prompts the construction workers to stop concrete pumping through sound and light to avoid over-pouring.

[0037] This method utilizes the characteristic of large specific gravity of concrete, senses the rising height of concrete through adjustable hydrometer 3, and reflects this height on scale 5 through float rod 4. When the top surface of concrete reaches the predetermined design height, float rod 4 triggers alarm 6 on the top of scale 5, thereby reminding construction personnel to stop pumping concrete through sound and light alarm, avoid over-pouring, and ensure construction accuracy. This construction control method can effectively prevent over-pouring of concrete and improve construction quality. At the same time, using adjustable hydrometer 3 and float rod 4, the rising height of the top surface of concrete can be monitored in real time to ensure that the top surface of concrete accurately reaches the design elevation. In addition, through the prompt of sound and light alarm 6, the pump truck is notified in time to stop concrete pumping to avoid rework and waste.

[0038] In this embodiment, the material of the fixing frame device 2 can be replaced according to the requirements of the construction environment, for example, a more corrosion-resistant or lighter material can be selected. In addition, the alarm 6 can be triggered mechanically or by an electronic sensor, so as to flexibly adapt to different construction site environments. The scale of the ruler 5 can be adjusted in accuracy according to actual needs to meet the requirements of different construction elevations.

[0039] The length of the borehole casing 1 is 3 to 5 meters. The length of the borehole casing 1 should be selected according to the construction environment and the requirements of soil stability. The length range of 3 to 5 meters can ensure the stability of the soil during the drilling process and provide sufficient support for subsequent construction. The borehole casing of this length can provide sufficient stability without causing too much impact on the construction operation. It adapts to the conventional pile foundation construction needs and ensures safe construction.

[0040] The length of the borehole casing 1 can be appropriately adjusted according to different geological conditions. If the construction geology is relatively soft, the length of the borehole casing 1 can be appropriately lengthened to enhance stability; and under relatively hard geological conditions, the length of the casing can be appropriately shortened.

[0041] The specific gravity setting range of the adjustable hydrometer 3 is 1.1 to 2.0, and the specific gravity setting range of the adjustable hydrometer 3 is adjusted according to the density of the concrete. The hydrometer determines the position of the top surface of the concrete by sensing the specific gravity of the concrete. When the specific gravity reaches the setting range, the floating rod 4 begins to rise. By setting the specific gravity range to 1.1 to 2.0, it is ensured that the hydrometer can accurately sense the rise of the top surface of the concrete. This range is suitable for most concrete pouring scenarios and provides precise control.

[0042] The specific gravity setting range of the adjustable hydrometer 3 can be adjusted according to the specific gravity of different types of concrete. For example, for lightweight concrete, the lower limit of the specific gravity may need to be adjusted to 1.0; for high-strength concrete, the upper limit of the specific gravity may be appropriately increased.

[0043] The rising height of the float rod 4 can be read in real time by the scale 5 on the side of the float rod 4. The rising height of the float rod 4 is displayed in real time through the scale 5. The construction personnel can observe the rising situation of the top surface of the concrete at any time to ensure that the top surface height meets the design requirements. The rising height of the float rod 4 is monitored in real time to ensure the accuracy and controllability of the concrete pouring process. The construction personnel can adjust the pumping speed at any time.

[0044] The ruler 5 can be replaced with different materials according to construction requirements, for example, a digital display can be used instead of a traditional ruler to achieve higher reading accuracy. A laser distance measuring device can also be used to replace the floating rod 4 to achieve contactless monitoring.

[0045] The scale 5 is set on the side of the float rod 4. When the top surface of the concrete reaches the designed height, the float rod 4 rises to the predetermined position of the scale 5 and triggers the alarm 6 on the top of the scale 5. The alarm 6 prompts the pump truck to stop pumping concrete through sound and light alarms. When the float rod 4 rises to the predetermined scale of the scale 5, the alarm 6 on the top of the scale 5 is triggered, and an sound and light signal is emitted to notify the pump truck to stop pumping to avoid excessive pouring. The double prompts of the alarm 6 can prevent human operating errors and further improve the accuracy and safety of construction.

[0046] The alarm 6 can select a wireless signal transmission device to send the signal to the operation room to achieve remote control. The sound and light signal can also be replaced by a vibration prompt to adapt to a noisy construction environment.

[0047] The alarm 6 is an audible and visual alarm installed on the top of the scale 5. When the top surface of the concrete reaches a predetermined height, the float rod 4 triggers the alarm 6, and notifies the construction personnel through audible and visual signals to prevent excessive pouring. When the float rod 4 rises to the predetermined position of the scale 5, the audible and visual alarm 6 is triggered to send a signal, and the construction personnel are prompted to stop concrete pumping through sound and light. The signal of the audible and visual alarm 6 is intuitive and clear, and can notify the construction personnel in time to avoid operational delays or errors and ensure the accuracy of construction.

[0048] The alarm 6 can be in various forms. In addition to sound and light prompts, it can also directly link the pump truck control system through wireless communication technology to automatically stop the pumping operation.

[0049] like Figure 2 and Figure 3 As shown, a construction control device for real-time monitoring of the concrete pile top elevation is also provided to implement the steps of the construction control method for real-time monitoring of the concrete pile top elevation, and the device comprises:

[0050] A borehole casing 1 is placed at the hole mouth to ensure the stability of the soil at the hole mouth;

[0051] A fixing frame device 2, the fixing frame device 2 is installed on the top of the drilling casing 1;

[0052] An adjustable hydrometer 3, which is mounted on the top of the borehole casing 1 through a fixing frame device 2;

[0053] A floating rod 4, which is installed on the top of the adjustable hydrometer 3 and rises as the adjustable hydrometer 3 rises;

[0054] A ruler 5, which is arranged on the side of the floating rod 4;

[0055] The trigger alarm 6 is installed on the top of the scale 5. When the floating rod 4 rises to a predetermined position of the scale 5, the trigger alarm 6 sends out an audible and visual alarm signal.

[0056] The core of the device is to monitor the height of the top surface of concrete in real time through the rising process of the floating rod 4. The floating rod 4 is connected to the adjustable hydrometer 3. When the top surface reaches the buoyancy tolerance range of the hydrometer 3 during the concrete pouring process, the floating rod 4 rises accordingly. The scale 5 records the rising height of the floating rod 4. When the floating rod 4 reaches the predetermined position of the scale 5, the alarm 6 is triggered to send a signal to remind the construction personnel to stop the concrete pumping in time. The device has a simple structure and a reasonable design. It can effectively monitor the elevation of the top of the concrete pile and prevent excessive concrete pouring. Through the coordinated work of the floating rod 4 and the adjustable hydrometer 3, real-time and accurate elevation monitoring is provided, which effectively improves the construction efficiency, ensures the pouring accuracy, and reduces construction errors.

[0057] The material of the borehole casing 1 can be changed according to the construction environment. For example, anti-corrosion steel or high-strength composite materials can be selected in a corrosive environment. The floating rod 4 can also be replaced with other types of rising monitoring devices, such as electronic sensors. The triggering mode of the alarm 6 can be changed from mechanical to electronic, and directly connected to the pump truck system to realize the automatic stop pumping function.

[0058] The adjustable hydrometer 3 is made of anti-corrosion materials and has scale marks for adjusting specific gravity. The adjustable hydrometer 3 can maintain stability and long-term use in harsh environments through its anti-corrosion materials. Its scale marks are used to adjust and calibrate the specific gravity range of the hydrometer 3 to ensure that it can adapt to the changes in specific gravity of different types of concrete. According to construction requirements, the specific gravity range of the hydrometer 3 is adjusted to ensure the adaptability of the hydrometer 3 under different concrete formulas. By using the adjustable hydrometer 3 made of anti-corrosion materials, the durability of the device is greatly improved, especially for humid, watery or highly acidic and alkaline environments. The setting of the scale marks makes the adjustment of the hydrometer 3 more intuitive, can flexibly respond to different construction requirements, and improves the adaptability of the device.

[0059] The anti-corrosion material of the hydrometer 3 can be stainless steel, engineering plastics or composite materials. The scale mark can be set to digital display, or the adjustment of the specific gravity can be recorded electronically to more accurately control the rising height of the floating rod 4.

[0060] The float rod 4 is a hollow structure. The float rod 4 adopts a hollow structure design, which can reduce its own weight and improve its sensitivity. When the adjustable hydrometer 3 floats up due to the rise of concrete, the float rod 4 can respond quickly and accurately reflect the height change of the top surface of the concrete. The hollow design also helps to reduce the use of materials and reduce production costs. The float rod 4 with a hollow structure design is light in weight and responsive. It can accurately rise with the rise of the top surface of the concrete, and promptly trigger the reading of the scale 5 and the prompt of the alarm 6. At the same time, the use of a hollow structure can effectively reduce equipment costs and improve the overall economy of the device.

[0061] The material of the floating rod 4 can be selected from light materials such as plastics and aluminum alloys. Waterproof foam material can also be filled in the hollow structure to increase its durability and buoyancy stability, ensuring that the floating rod 4 is not easily deformed or invalid during long-term use.

[0062] The scale 5 is made of wear-resistant and weather-resistant materials, and has an anti-skid texture on the surface of the scale. The scale 5 is made of wear-resistant and weather-resistant materials to ensure that it can be used for a long time outdoors or in harsh environments, and the scale is clear and the accuracy remains unchanged. The anti-skid texture design on the surface facilitates construction personnel to quickly read data when monitoring the rise of the float rod 4, and prevents the surface of the scale from becoming slippery under the influence of mud or other stains, thereby affecting the accuracy of the reading. The use of wear-resistant and weather-resistant materials greatly extends the service life of the scale 5, and is particularly suitable for construction sites that are exposed to the external environment for a long time. The anti-skid texture design allows construction personnel to read the data on the scale more conveniently and quickly, reducing operational errors and improving the accuracy and efficiency of construction.

[0063] The material of the ruler 5 can be replaced with plastic, alloy or carbon fiber material according to construction requirements to adapt to different environmental conditions. The anti-slip texture design can be an uneven surface, or a fluorescent or reflective coating can be added to improve visibility at night or in low light environments.

[0064] Working process: In order to ensure the stability of the soil at the hole mouth during bored pile construction, a 3-5m steel casing is generally placed at the hole mouth as a protective structure. After the bored pile is bored, a steel cage is placed, and a 6-fixture device is installed on the top of the steel casing, and an adjustable hydrometer 3 and a floating rod 4 are installed in conjunction. During the concrete pouring process, the bottom is concrete and the upper part is mud. As the concrete is continuously poured in, the boundary liquid level between the concrete and the mud continues to rise. Since the specific gravity of concrete is about 2.2 and the specific gravity of mud is about 1.03, the specific gravity of the adjustable hydrometer is set between 1.1-2.0. When the cross-section position reaches the hydrometer position, due to the larger specific gravity of concrete and the smaller specific gravity of mud, as the top surface of concrete rises, under the action of buoyancy, the adjustable hydrometer 3 rises accordingly, and the floating rod 4 installed on the top of the adjustable hydrometer continues to rise. The scale 5 is fixed on the side of the floating rod 4, and the rising height of the floating rod 4 can be read. When the top surface of concrete rises to the designed position, the adjustable hydrometer 3 and the floating rod 4 rise to the predetermined position of the scale 5, and trigger the trigger alarm 6 on the top of the scale. Through the dual prompts of the scale 5 reading and the trigger alarm 6, the pump truck is notified to stop concrete pumping to prevent excessive pouring, and the concrete pouring height of the bored pile can be grasped in real time.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
