Description

TECHNICAL FIELD

[0001] The present application relates to the field of grouting monitoring equipment, in particular to a PC sleeve grouting monitor. BACKGROUND

[0002] The common longitudinal steel bar connection methods in cast-in-place concrete structure include binding lap joint, welding connection and mechanical connection, etc. Since the connecting part of fabricated concrete structure is small, it is not convenient to use these traditional steel bar connection methods for construction. The grouting sleeve is a combination of specially processed sleeve, matching grouting material and steel bar. When connecting the steel bar, the fast-hardening and non-shrinkage grouting material is injected to connect the steel bar and the sleeve by the bonding and biting effect between the materials.

[0003] After the above grouting process is completed, the fullness of grouting needs to be observed by the monitor. The existing sleeve grouting monitor is an L-shaped communicating pipe designed based on the communicating vessel principle. The communicating pipe is divided into a vertical branch and a horizontal branch which are perpendicular to each other. The horizontal branch is used for inserting the grouting pipe of the sleeve, and the vertical branch is the monitoring end used for monitoring the flow of the grouting material. The monitor judges the fullness of grouting by monitoring the flow of the grouting material. When the monitor observes that the fullness of the grouting material meets the requirements, the part of the horizontal branch inserted into the sleeve is knocked off after the grouting material is coagulated, so as to realize the separation of the monitor and the sleeve.

[0004] In actual operation, the above monitor has the following problems when used: the vertical branch as the monitoring end has a small diameter, the space for the grouting material to flow smoothly is small, and the connection angle between the horizontal branch and the vertical branch is like a foot, so that the grouting material is difficult to flow back to the vertical branch smoothly, and the grouting material is easy to be stuck, thereby causing misjudgment of the fullness of grouting, and thus the subsequent supplementary grouting workload is large. SUMMARY

[0005] In order to solve the problems in the above technology, the present application provides a PC sleeve grouting monitor.

[0006] The PC sleeve grouting monitor provided by the present application adopts the following technical scheme:

[0007] A PC sleeve grouting monitor, comprising a connecting section and a monitoring section, the connecting section comprising a first branch and a second branch, the first branch, the second branch and the monitoring section being sequentially communicated, the connection angle between the first branch and the second branch being an obtuse angle, and the monitoring section being funnel-shaped and having a small diameter at one end communicated with the second branch.

[0008] By adopting the technical scheme, the first branch is used for connecting the pulp inlet pipe of the sleeve, and the monitoring section is used for observing the backflow of the pulp, so as to judge the fullness of the grouting. Since the monitoring section is funnel-shaped, the hole diameter gradually increases at the connection between the first branch and the second branch, so that the pulp can flow smoothly in a larger space, and the connection angle between the first branch and the second branch is obtuse, so that the pulp will not be stuck at the connection between the first branch and the second branch. Between the double settings, the monitor can improve the greater back-falling potential, so that the amount of pulp back-falling is satisfied, and the pulp can flow smoothly on the first branch, the second branch and the monitoring section, so as to avoid the situation that the pulp is stuck and does not back-fall, thereby improving the occurrence of misjudgment. In addition, since the monitoring section is funnel-shaped, the overall space is large, and it is also easier to observe the backflow of the pulp. When the liquid level of the pulp observed through the monitoring section is found to be falling, that is, the fullness of the grouting does not meet the requirements, the pulp can be supplemented through the monitoring section, thereby improving the convenience of the supplemental irrigation operation.

[0009] Optionally, a first rubber sleeve is sleeved on one end of the first branch away from the second branch, and the first rubber sleeve is sleeved on the pulp inlet pipe of a sleeve.

[0010] By adopting the technical scheme, the first branch is connected with the pulp inlet pipe of the sleeve through the first rubber sleeve, so that the connection and separation of the first branch and the pulp inlet pipe are facilitated, and the convenience in the installation and disassembly process of the monitor is further improved. When the monitoring operation of the grouting is completed, the monitor can be disassembled by separating the first rubber sleeve from the pulp inlet pipe. At this time, the integrity of the monitor is maintained, and the monitor can be repeatedly used, thereby saving the use cost.

[0011] Optionally, a second rubber sleeve is sleeved on one end of the second branch away from the first branch, and the second rubber sleeve is sleeved on one end of the monitoring section with a smaller diameter.

[0012] By adopting the technical scheme, the second branch and the monitoring section are detachably connected through the second rubber sleeve, so that the separation of the monitoring section and the second branch is facilitated. When the connection section or the monitoring section is damaged and needs to be replaced during long-term use of the monitor, the second rubber sleeve can be detached, so that the separation of the monitoring section and the connection section is completed. At this time, the damaged parts can be replaced individually without replacing the whole monitor, thereby reducing the cost of loss.

[0013] Optionally, a transparent film and a control member are arranged on the monitoring section, and the control member is used for adsorbing and adhering the transparent film to the inner side wall of the monitoring section.

[0014] By adopting the technical scheme, when in use, the monitor adsorbs the transparent film through the control member, so that the transparent film is attached to the inner side wall of the monitoring section; when the slurry loop or the slurry is supplemented through the monitoring section, the slurry directly contacts the transparent film; when the monitor is used up, the control member releases the control on the transparent film, so that the transparent film can be separated from the monitoring section, and then the slurry on the transparent film can be recycled; compared with pouring the slurry from the monitoring section to recycle the slurry, the transparent film is taken off from the monitoring section, and then the slurry on the transparent film can be scraped off, which is more conducive to the separation of the slurry, thereby being conducive to the recycling of the slurry and recycling as much slurry as possible; in addition, when the monitor is used up, the monitoring section is still in a clean state after the transparent film is separated from the monitoring section, thereby reducing the burden of subsequent cleaning operation of the monitor.

[0015] Optionally, the monitoring section comprises an inner ring and an outer ring, a grouting channel communicated with the second branch is formed in the inner ring, and an air cavity is surrounded between the inner ring and the outer ring; the control member comprises a gas control source for controlling the gas in the air cavity, and a plurality of air permeation holes communicated with the air cavity are formed in the inner ring.

[0016] By adopting the technical scheme, the gas control source is used to control the gas in the air cavity; when the gas in the air cavity is extracted through the gas control source, the transparent film is adsorbed and attached to the inner side wall of the inner ring; when the monitor is used up, the gas is introduced into the air cavity through the gas control source, and the gas is then blown out through the air permeation holes, thereby achieving the toppling of the transparent film, and then the transparent film can be separated from the inner ring.

[0017] Optionally, the air permeation hole is provided with an air permeation film.

[0018] By adopting the technical scheme, by providing the air permeation film at the air permeation hole, the extraction of the gas in the air cavity through the gas control source can be avoided, so that the transparent film is not sucked into the air permeation hole.

[0019] Optionally, a placing cavity is formed in the monitoring section, a winding roller is arranged in the placing cavity, and the transparent film is wound on the winding roller; a cutting cavity is formed in the monitoring section, an opening of the cutting cavity is communicated with an opening of the placing cavity, and a cutting blade for cutting the transparent film is slidably arranged in the cutting cavity.

[0020] By adopting the above technical scheme, the transparent film is wound on the winding roller, and the winding roller is arranged in the placing cavity. When the monitor is used each time, the transparent film is taken out, the transparent film is moved out through the opening of the placing cavity and is attached to the inner side wall of the monitoring section. When the use of the single transparent film is completed, the sliding cutting blade is moved out of the cutting cavity, the transparent film is cut by the cutting blade, and the remaining transparent film on the winding roller can be used next time. Therefore, the monitor is convenient to use. When the monitor is used each time, the transparent film does not need to be prepared or carried additionally, so that the transparent film is not missed.

[0021] Optionally, the cutting blade is fixed with a sliding block, the cutting cavity is provided with a sliding groove, the sliding block is located in the sliding groove and is in sliding cooperation with the sliding groove, and the sliding groove is fixed with a limiting plate for preventing the sliding block from being separated from the sliding groove.

[0022] By adopting the above technical scheme, when the cutting blade slides, the sliding block synchronously slides in the sliding groove. When the sliding block moves to abut against the limiting groove, the sliding of the sliding block in the same direction is limited. At this time, the cutting blade slides to the farthest end. The cooperation of the sliding block and the sliding groove limits the sliding direction of the cutting blade, so that the stability of the cutting blade in the sliding process is improved, and the misalignment of the cutting blade in the sliding process is avoided.

[0023] Optionally, the cutting cavity is provided with a spring, and the spring is fixedly connected with the cutting blade at the end.

[0024] By adopting the above technical scheme, when the cutting blade slides to contact the transparent film and cut the transparent film, the spring is in a stretched state. When the cutting of the cutting blade is completed, the spring is rebounded to pull the cutting blade to reset. Therefore, the stability of the cutting blade when the cutting blade does not perform the cutting operation is improved, and the cutting blade is prevented from sliding when the cutting is not needed, so that the transparent film is not cut by mistake.

[0025] Optionally, a plurality of sealing pads are arranged at the opening of the cutting cavity, and the sealing pads are attached to each other or partially overlap to seal the cutting cavity.

[0026] By adopting the above technical scheme, when the transparent film does not need to be cut, the cutting blade is located in the cutting cavity, and the plurality of sealing pads are attached to each other or partially overlap to seal the cutting cavity. Therefore, when the transparent film is taken out, the transparent film is not touched by mistake with the cutting blade, so that the transparent film is not cut by accident.

[0027] In summary, the present application has at least one of the following beneficial technical effects:

[0028] 1. The monitor can improve the large falling potential energy, so that the amount of slurry falling is satisfied, the slurry can smoothly flow on the first branch, the second branch and the monitoring section, so that the slurry is not stuck and the slurry does not fall, and the false judgment is improved.

[0029] 2. The monitoring section is funnel-shaped, has a large overall space, and is more conducive to observing the backflow of the slurry. When the liquid level of the slurry is observed to drop through the monitoring section, that is, the fullness of the grouting does not meet the requirements, the slurry can also be supplemented through the monitoring section, thereby improving the convenience of the supplemental grouting operation;

[0030] 3. The transparent film is removed from the monitoring section, and then the slurry on the transparent film can be scraped off, which is more conducive to the separation of the slurry, thereby facilitating the recycling of the slurry and enabling as much slurry as possible to be recycled. In addition, when the monitor is used up, the transparent film is separated from the monitoring section, and the monitoring section is still in a clean state, thereby reducing the burden of subsequent cleaning operations on the monitor.

DETAILED DESCRIPTION

[0037] The following will be described in detail in combination with the accompanying drawings. Figures 1-5 The present application is further described in detail.

[0038] The embodiment of the present application discloses a PC sleeve grouting monitor. Referring to Figure 1The PC sleeve grouting monitor comprises a connecting section 1 and a monitoring section 2, the connecting section 1 comprises a first branch 101 and a second branch 102, the first branch 101, the second branch 102 and the monitoring section 2 are sequentially communicated, the connecting angle between the first branch 101 and the second branch 102 is an arc angle of 135°, and the monitoring section 2 is funnel-shaped and the smaller-diameter end of the monitoring section 2 is communicated with the second branch 102.

[0039] With reference to Figure 1 The end of the first branch 101 away from the second branch 102 is sleeved with a first rubber sleeve 3 of 2 cm, the end of the first rubber sleeve 3 away from the second branch 102 is sleeved on the grouting pipe of a sleeve, the end of the second branch 102 away from the first branch 101 is sleeved with a second rubber sleeve 4 of 5 cm, and the end of the second rubber sleeve 4 away from the second branch 102 is sleeved on the smaller-diameter end of the monitoring section 2.

[0040] In use, the end of the second branch 102 away from the monitoring section 2 is sleeved into the second rubber sleeve 4 to a depth of 2.5 cm, the ends of the monitoring section 2 and the first branch 101 close to each other are respectively sleeved into the first rubber sleeve 3 to a depth of 1 cm, and the second branch 102 and the monitoring section 2 are thus detachably connected through the second rubber sleeve 4, so that the separation of the monitoring section 2 and the second branch 102 is facilitated, the first branch 101 is communicated with the grouting pipe of the sleeve through the first rubber sleeve 3, and the connection and separation of the first branch 101 and the grouting pipe are facilitated, and when the monitoring operation of grouting is completed, the first rubber sleeve 3 is separated from the grouting pipe, and the dismounting operation of the monitor is completed, and the integrity of the monitor as a whole is maintained.

[0041] In the embodiment, the material of the monitoring section 2 is transparent plastic, and the materials of the first branch 101 and the second branch 102 are PVC pipes.

[0042] With reference to Figure 2 and Figure 3 The monitoring section 2 comprises an inner ring 201 and an outer ring 202, a transparent film is adsorbed on the inner side wall of the inner ring 201 and is attached to the inner side wall of the inner ring 201, a grouting channel 5 is formed in the inner ring 201 and communicated with the second branch 102, and an air cavity 6 is enclosed between the inner ring 201 and the outer ring 202; an air control source 7 is installed on the outer ring 202 and used to draw or introduce gas into the air cavity 6, a plurality of air permeable holes 8 are formed in the inner ring 201 and communicated with the air cavity 6, and air permeable films are arranged at the air permeable holes 8.

[0043] With reference to Figure 2 and Figure 4 A placing cavity 9 is formed in the monitoring section 2, a winding roller 10 is rotationally arranged in the placing cavity 9, and the transparent film is wound on the winding roller 10; a cutting cavity 11 is formed in the monitoring section 2, the opening of the cutting cavity 11 is communicated with the opening of the placing cavity 9, and a cutting blade 12 used to cut the transparent film is slidably arranged in the cutting cavity 11.

[0044] The transparent film is wound on the winding roller 10, and the winding roller 10 is arranged in the placing cavity 9. When the monitor is used each time, the transparent film is drawn out, the transparent film is moved out through the opening of the placing cavity 9 and is attached to the inner side wall of the monitoring section 2, the gas in the gas cavity 6 is drawn through the gas control source 7, and the transparent film is adsorbed and attached to the inner side wall of the inner ring 201. When the slurry is supplemented through the monitoring section 2 or the slurry loop, the slurry directly contacts the transparent film. When the monitor is used up, the gas is introduced into the gas cavity 6 through the gas control source, the gas is then blown out through the air hole 8, the transparent film is thus pushed, and then the transparent film can be separated from the inner ring 201. The slurry on the transparent film can be recycled. When the use of the single transparent film is completed, the sliding cutting blade 12 is moved out of the cutting cavity 11, the transparent film is cut through the cutting blade 12, and the remaining transparent film on the winding roller 10 can be used next time.

[0045] With reference to Figure 3 and Figure 4 The sliding block 13 is fixed on the cutting blade 12, the sliding groove 14 is arranged in the cutting cavity 11 and communicates with the cutting cavity 11, the sliding block 13 is located in the sliding groove 14 and is in sliding fit with the sliding groove 14, and the limiting plate 20 for preventing the sliding block 13 from being separated from the sliding groove 14 is fixed in the sliding groove 14. The spring 15 is fixed in the sliding groove 14, the end of the spring 15 is fixedly connected with the sliding block 13, and the two sealing pads 16 are fixed at the opening of the cutting cavity 11 and abut against each other to close the cutting cavity 11.

[0046] When the transparent film does not need to be cut, the cutting blade 12 is located in the cutting cavity 11, and the multiple sealing pads 16 abut against each other or partially overlap to close the cutting cavity 11, so that the transparent film is prevented from being contacted with the cutting blade 12 in the process of being pulled out. When the transparent film needs to be cut, the cutting blade 12 slides, the cutting blade 12 is moved out from between the two sealing pads 16 when the cutting blade 12 slides to the sealing pads 16, the sliding block 13 synchronously slides in the sliding groove 14, the sliding block 13 is limited to slide in the same direction when the sliding block 13 moves to abut against the limiting groove, the cutting blade 12 slides to the farthest end at this time, the cutting end of the cutting blade 12 is in contact with the inner wall of the placing cavity 9, the transparent film between the inner wall and the cutting end of the cutting blade 12 is thus cut through by cooperation with the inner wall, and the spring 15 is in a stretched state at this time. When the cutting of the cutting blade 12 is completed, the spring 15 is rebounded to pull the cutting blade 12 back to the original position.

[0047] In the embodiment, the end of the spring 15 is fixedly connected with the sliding block 13, and the spring 15 is indirectly fixedly connected with the cutting blade 12. In other embodiments, the spring 15 can be directly fixedly connected with the cutting blade 12.

[0048] With reference to Figure 4 andFigure 5 The top end of the outer ring 202 is provided with a sliding channel 19, which is communicated with the cutting cavity 11, and a control rod 17 is slidably arranged in the sliding channel 19, one end of the control rod 17 is fixedly connected with the cutting blade 12, and the other end is connected with a control block 18, the control block 18 is located outside the cutting cavity 11, and the sliding of the control block 18 drives the sliding of the control rod 17, and then the sliding of the cutting blade 12 is realized.

[0049] The implementation principle of the PC sleeve grouting monitor of the embodiment of the application is as follows: the first branch 101 is used to communicate with the grouting pipe of the sleeve, and the monitoring section 2 in the form of a funnel formed by the inner ring 201 and the outer ring 202 is used to observe the backflow of the slurry, so as to judge the fullness of grouting. Since the grouting channel 5 formed in the inner ring 201 is in the form of a funnel, the hole diameter increases successively at the connection position with the second branch 102, so that the space for smooth flow of the slurry is large, and the connection angle between the first branch 101 and the second branch 102 is obtuse, so that the slurry will not be stuck at the communication position of the first branch 101 and the second branch 102. Between the double sets of cooperation, the whole monitor can improve the large back-falling potential energy, so that the amount of back-falling of the slurry is satisfied, and the slurry can flow smoothly in the first branch 101, the second branch 102 and the inner ring 201, so as to avoid the situation that the slurry does not back-fall due to the slurry being stuck, thereby improving the occurrence of misjudgment. In addition, since the whole space in the inner ring 201 is large, it is also easy to observe the back-falling of the slurry. When the liquid level of the slurry is observed to drop, that is, the fullness of grouting does not meet the requirements, the slurry can also be supplemented through the inner ring 201, so as to improve the convenience of supplemental irrigation.

[0050] The above are the preferred embodiments of the application, which do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
