Description

Technical Field

[0001] The invention belongs to the technical field of concrete pouring, and in particular relates to a novel concrete pouring construction method. Background Art

[0002] With the continuous development of construction engineering technology, concrete pouring construction occupies an important position in the fields of roads, bridges, buildings, etc. When pouring concrete, pouring formwork and liquid concrete are required. After spreading, vibration and curing, it is poured into shape.

[0003] In general casting process, due to the large volume and complex structure of large-volume concrete, and the fact that concrete is a poor conductor of heat, the heat of cement hydration accumulates inside the structure and is difficult to diffuse. If this heat control problem is not solved well, it is easy to cause cracks in large-volume concrete, affecting the integrity and durability of the structure and endangering the safety of the structure. The concrete volume is large, the construction and maintenance conditions are complex, and the heat of cement hydration is easy to accumulate and cause temperature deformation of the structure. In engineering practice, measures should be taken as much as possible to detect and control the heat release of concrete hydration to reduce the cracks caused by deformation of large-volume concrete as much as possible. For this purpose, Chinese patent CN108487288B discloses a construction process for layered casting of large-volume concrete caps; including: excavating a foundation pit at a set position, excavating at least one reinforcement hole at the bottom of the foundation pit, placing a steel cage in at least one reinforcement hole and casting concrete, casting the cap in layers from bottom to top, and cooling the cap with a cooling water pipe after casting. At least one reinforcement hole is arranged at the bottom of the foundation pit. During the pouring of the pedestal, the reinforcement hole is poured first. After the pouring of the pedestal, there is at least one reinforcement bar formed by reinforced concrete at the bottom. The overall structure of the pedestal is more solid and reliable, and it is safer to use. The temperature of the pedestal is controlled by a cooling water pipe, which effectively improves the cracking of the pedestal and the quality of the pedestal is high. However, in the above structure, the cooling power is adjusted according to the actual temperature, and the precise control of the temperature is failed to be achieved. The cooling effect is general. Therefore, a new concrete pouring construction method with good cooling effect is needed. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the present invention provides a novel concrete pouring construction method, which has the characteristics of good cooling effect.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0010] Step 4: The flow rate and direction of the concrete are controlled by the distribution module. The vibration module vibrates the poured concrete in time to expel internal bubbles. At the same time, the cooling module increases the power when the temperature exceeds the threshold and reduces the power when the temperature is below the threshold.

[0011] As a preferred technical solution of the present invention, step four includes: the temperature sensor detects the temperature of the casting area and uploads the temperature data set to the control module, and the control module adjusts the cooling module power to P, wherein P=T / T0×P0, T0 is a pre-input temperature reference value, and P0 is a pre-input power threshold.

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] See also Figure 1-2 , a new concrete pouring construction method, comprising the following steps:

[0028] Step 1: Arrange a cloth module 2 and a vibration module 3 on a mobile platform 1;

[0029] Specifically, the mobile platform 1 is used to support the construction device on the upper layer to achieve rapid movement and positioning. The construction device includes a distribution module 2 and a vibration module 3. The distribution module 2 is arranged on the mobile platform 1. The distribution module 2 controls the spraying speed and spraying position of the concrete to achieve uniform pouring. The vibration module 3 is used to vibrate the concrete to eliminate bubbles inside the concrete and improve the density.

[0030] Specifically, the vibration module 3 includes at least a vibration motor and a vibrating rod. A crane as a transmission module 31 is provided on the mobile platform 1. The vibration motor and the vibrating rod are provided on the crane. The crane is used to adjust the position of the vibrating rod.

[0031] At the same time, a concrete storage is provided on the mobile platform 1, and the concrete storage is used to receive concrete transported from the mixing plant to the mobile platform 1;

[0032] Step 2: Set up temperature sensors and cooling modules around the pouring area;

[0033] In this embodiment, the casting area is a hollow area surrounded by a template, a temperature sensor and a cooling module are arranged around the template, and the temperature sensor and the cooling module are electrically connected to a control module 4, and the control module 4 adjusts the power of the cooling module and receives data from the temperature sensor;

[0034] Specifically, the cooling module can be a water cooling module arranged around the outside of the template, or an air cooling module covering the space enclosed by the template;

[0035] Step 3: The mobile platform 1 drives the material distribution module 2 and the vibration module 3 to the pouring area;

[0036] According to the construction requirements, the operator moves the mobile platform 1 to the pouring area and prepares for pouring;

[0037] Step 4: The flow rate and direction of the concrete are controlled by the distribution module 2, and the vibration module 3 vibrates the poured concrete in time to expel internal bubbles. At the same time, the cooling module increases the power when the temperature exceeds the threshold, and reduces the power when the temperature is below the threshold;

[0038] Specifically, the crane moves the vibrating rod to the top of the concrete that needs to be vibrated, the vibrating rod vibrates the concrete that needs to be vibrated, and the vibration motor transmits the vibration to the vibrating rod;

[0039] At the same time, the temperature sensor monitors the temperature change during the concrete pouring process in real time, detects the temperature of the pouring area and uploads the temperature data T to the control module 4, and the control module 4 adjusts the cooling module power to P, where P = T / T0×P0, T0 is the pre-input temperature reference value T0, and P0 is the pre-input power threshold;

[0040] When the temperature data is large, it means that the cooling power needs to be increased. At this time, the value of P=T / T0×P0 is large. When the control module 4 adjusts the cooling module power to P, the cooling power is increased when the temperature is high. When the temperature data is small, it means that the cooling power does not need to be increased. At this time, the value of P=T / T0×P0 is small, and the cooling power is reduced when the temperature is low.

[0041] By setting a temperature sensor to detect the temperature of the pouring process, the cooling module increases the power when the temperature exceeds the threshold and reduces the power when the temperature is below the threshold, thereby increasing the cooling power when the temperature is high and reducing the cooling power when the temperature is low.

[0042] Step 5: Perform concrete curing. After the concrete is poured, proper curing and protection are performed to ensure the strength and durability of the concrete. In this embodiment, the curing process includes covering to keep the concrete moist, spraying curing agents, and setting up sunshade facilities. At the same time, the construction site is closed to prevent external factors from damaging the concrete.

[0043] In step 2: a plurality of cooling modules are arranged around the casting area; step 4 also includes: a temperature sensor detects the highest temperature point and instructs the cooling modules near the highest temperature point to increase the power;

[0044] Specifically, the control module 4 pre-establishes a coordinate system including the positions of several cooling modules. When the temperature sensor detects the highest temperature point, the coordinates of the highest temperature point are synchronously detected and uploaded to the control module 4. The coordinate system of the highest temperature point and the coordinate system including the positions of several cooling modules are the same coordinate system. The control module 4 determines the cooling module closest to the highest temperature point and instructs the cooling module to increase the power.

[0045] By having the temperature sensor detect the highest temperature point and instructing the cooling module near the highest temperature point to increase the power, the cooling effect is further improved;

[0046] In the above process, specifically, the temperature sensor is used to measure the highest temperature point, the control module 4 calculates the distance c between the highest temperature point and the cooling module nearby, and the control module 4 adjusts the cooling power to P×A1, wherein A1=(c0 / c+1), c0 is a pre-input distance constant, when c is small, it means the distance is close, the cooling effect is good, and the power of the cooling module closest to the highest point needs to be increased, at this time A1=(c0 / c+1) increases, exceeds 1, and the power of the cooling module closest to the highest point needs to be increased, and the power of the cooling module is further corrected upward, when c is large, it means the distance is close, and the additional upward correction effect is not obvious, and there is no need to excessively increase the power of the cooling module closest to the highest point, at this time A1=(c0 / c+1) decreases, close to 1, and the power of the cooling module is maintained unchanged when there is no need to increase the power of the cooling module closest to the highest point.

[0047] In some cases, some data collected by the temperature sensor may be affected by random factors such as environmental factors or equipment failures, resulting in the collected data being unable to reflect the real data. This temperature data is usually more discrete than other data, affecting the accuracy of temperature detection, and further affecting the cooling effect based on temperature detection. To improve the accuracy of temperature detection, the temperature sensor collects and uploads a number of temperature data, and the control module 4 determines whether the variance of the temperature data is greater than a threshold value. When the judgment result is yes, the temperature data with the largest discreteness is deleted;

[0048] Specifically, the temperature data uploaded by the temperature sensor each time are recorded as the same batch of data. After receiving a batch of data, the control module 4 calculates the variance of this batch of data and determines whether it is greater than a threshold value. When the judgment result is yes, it means that the discreteness in this batch of data is large, and there is a high probability that the collected data cannot reflect the real data. A certain temperature data has a large discreteness relative to other data. At this time, it is necessary to exclude the data with large discreteness to reduce the influence of the error data on the accuracy of temperature detection. At this time, the control module 4 calculates the discreteness of each data in this batch of data, and removes the data with the highest discreteness in this batch of data, completes the exclusion of the data affected by random errors, and improves the accuracy of temperature measurement;

[0049] By making the control module 4 determine whether the variance of several temperature data is greater than a threshold value, the temperature data with the largest discreteness is deleted when the determination result is yes, thereby reducing the influence of data affected by random errors on temperature detection, thereby reducing the influence of this data on the cooling effect based on temperature detection, and improving the cooling effect.
