Description
Technical Field
The utility model relates to a slip casting construction technical field specifically is a can assist the play thick liquid pipe of assembled structure mud jacking compactness in the evaluation work progress.
Background
The connection between the prefabricated components of the civil engineering fabricated structure is mainly realized by a sleeve connection mode at present. The sleeve is prefabricated in the assembled component, in the field construction process, the adjacent prefabricated components need to be aligned in place, and then liquid grouting material is pressed into the sleeve (hereinafter referred to as grouting) by adopting a professional grouting device in a pressure applying mode, so that the sleeve is filled with the grouting material. The grouting material has self-solidification and micro-expansion characteristics, and after the grouting material is solidified automatically, the sleeve is filled with the solid formed by the solidification of the grouting material. At this point, a tight, secure and effective connection is formed between the prefabricated elements.
After grouting construction is finished, whether the sleeve is filled with grouting material (grouting compactness for short) is an important index for evaluating grouting quality. Currently, most methods for detecting the grouting compactness comprise nondestructive detection methods such as ultrasonic waves and CT scanning or destructive detection methods such as open pore endoscopy. The methods are carried out after the grouting material is solidified, and belong to post detection methods. The post-detection method can accurately evaluate the grouting compactness, but the grouting material is solidified at the moment, so that remedial measures are difficult to take. Compared with the post detection method, the in-process detection method (in the construction process) is urgently required by the engineering community. At present, an in-service detection method mainly adopts an embedded sensor method, the method needs to embed a sensor in a pulp outlet pipe before grouting in advance, and the grouting compactness is evaluated by testing two readings of the sensor before grouting and after grouting. However, this type of sensor is disposable, requires pre-embedding on each sleeve to be tested, and requires special data acquisition equipment, and therefore, is economically disadvantageous for large-scale deployment.
In summary, the engineering industry needs low-cost and convenient equipment and method for detecting the grouting compactness in the construction process (in operation).

Detailed Description
The structure and principle of such a device will be apparent to those skilled in the art from the following further description of the invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in figure 1 and figure 2, a can assist the play thick liquid pipe of evaluation assembled structure mud jacking compactness in the work progress, including a thick liquid pipe, play thick liquid pipe includes anchor section, scale section and turns to the section, and anchor section level is placed, and the scale section is vertical to be placed, turns to the both ends of section and connects respectively in anchor section and scale section to anchor section and scale section form the right angle form through turning to the section connection. The steering section is tightly connected with the anchoring section and the scale section in a socket-and-spigot manner. And one end of the anchoring section is connected with a grout outlet at the top of the embedded sleeve in a thread mode. The anchoring section, the scale section and the steering section can be made of common rigid polyvinyl chloride (PVC) materials or transparent PVC materials, the cost of the pipeline is low, and the economical efficiency is obvious compared with other detection modes in the process.
The steel bars generally penetrate through the embedded sleeves and penetrate through the splicing interface of the two prefabricated parts. And a grouting nozzle of the grouting equipment injects grouting material into the embedded sleeve through the grouting opening. The highest position of the scale section in the grout outlet pipe is higher than the highest position of the embedded sleeve so as to ensure that the top of the embedded sleeve is filled with grouting material.
In the grouting construction process, after grouting materials emerge from the top of the scale section in the grout outlet pipe, grouting is stopped, and a grouting opening is rapidly blocked. At the moment, the liquid level of the grouting material is flush with the top of the scale section in the grout outlet pipe. After waiting for a period of time, reading out the height of liquid level reduction of the grouting material in a visual inspection mode according to a scale of a scale section in the grout outlet pipe, determining whether incompact possibility exists according to the calibration relation between the height of reduction and compactness, and determining whether grout is supplemented in time before the grouting material is solidified. The waiting time is related to the characteristics (especially the setting time) of the grouting material, the size of the embedded sleeve and other factors, and needs to be calibrated in a scientific test mode before construction. Meanwhile, the relation between the height of the liquid level drop of the grouting material and the compactness and the corresponding disposal measures also need to be determined through tests before construction.
Further, the basic principle of judging the grouting compactness through the liquid level change in the scale section is as follows:
1) in ideal grouting construction, the highest liquid level of liquid grouting material is continuously increased in the embedded sleeve along with the grouting process, the embedded sleeve below the liquid level is completely filled with the grouting material, finally, the liquid level is increased to the anchoring section, the steering section and the scale section, and grouting is stopped and a grouting opening is blocked after the scale section overflows. At the moment, the embedded sleeve is not provided with an uncompacted space caused by cavities, air bubbles and the like, and the slurry does not flow back into the embedded sleeve but forms a slight bulge at the section opening of the scale in the process of gradually solidifying the grouting material by combining the characteristic of micro-expansion of the grouting material;
2) for the construction condition that grouting is not compact due to the fact that cavities, bubbles and the like occur in the embedded sleeve in the grouting process, after the grouting material overflows the scale section opening and the grouting opening is blocked, the liquid grouting material can gradually flow back into the embedded sleeve under the action of the self weight and the buoyancy of the grouting material, the non-compact spaces such as the cavities, the bubbles and the like generated in the construction process are filled, and at the moment, the liquid level originally located at the identification section opening is gradually reduced;
3) therefore, the condition that grouting is not compact in the construction process can be qualitatively judged by the phenomenon that the liquid level of the scale section descends, and the size of the inner non-compact space can be quantitatively judged by the descending height of the liquid level, so that the non-compact condition in the original construction process can be further judged;
4) the possible severity of the internal defect can be judged through the relation between the liquid level descending height and the non-compactness, and whether remedial measures are taken or not is determined before the grouting material is not solidified.
Fig. 3a and 3b further illustrate two different types of scale representation of scale segments, including both inner wall ribbed scale segments (fig. 3 a) and scale segments with marked lines painted on the inner wall (fig. 3 b). The scale section with the ribs on the inner wall can avoid the situation that scale marks are not clear and cannot be read due to the fact that the scale sections are attached to the inner wall in the slurry descending process; the scale section of spraying marking on the inner wall can use transparent PVC pipeline preparation to print the altitude scale on scale section outer wall, scale and scale pipe inner wall grout material's liquid level at ordinary times during the reading.
Fig. 4a, 4b, 4c, and 4d further illustrate the rib form of the inner wall ribbed scale segment of fig. 3a, including but not limited to four, three, two, and one rib segments.
The utility model discloses still have following operating method:
grouting equipment pours into grouting material into embedded sleeve's inner chamber through the slip casting mouth, and along with going on of mud jacking process, grouting material fills up embedded sleeve's inner chamber gradually, finally through the scale section and spill over the top of scale section. Then the grouting is stopped and the grouting port is quickly plugged. At the moment, the liquid level of the grouting material is flush with the top of the scale section in the grout outlet pipe. After waiting for a period of time, reading out the height of liquid level reduction of the grouting material in a visual inspection mode according to a scale of a scale section in the grout outlet pipe, determining whether incompact possibility exists according to the calibration relation between the height of reduction and compactness, and determining whether grout is supplemented in time before the grouting material is solidified.
To sum up, the utility model discloses can read out the height that grout liquid level descends through the mode of range estimation according to the scale of the scale section in the grout outlet pipe, can be used to the closely knit degree of supplementary evaluation mud jacking to simple structure, convenient operation, the cost is lower.
