Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction technology, and in particular to a grouting device for road and bridge construction. Background Technology

[0002] Grouting devices for road and bridge construction are specialized mechanical equipment designed for engineering scenarios such as roadbed reinforcement, bridge bearing filling, structural crack repair, and tunnel surrounding rock stabilization. Their core function is to use a power system to precisely deliver grouting materials with specific fluidity and curing properties, such as cement grout, cement mortar, and chemical grout, to the voids, cracks, or weak strata inside the road and bridge structure at preset pressure and flow rate. After the grout solidifies, it forms a dense cementitious body, thereby achieving the construction objectives of filling voids, sealing leaks, enhancing the overall structure and load-bearing capacity, and improving the stress state of the foundation.

[0003] After the grouting operation is completed, a certain amount of grout may remain inside the grouting pipe. This grout will continue to adhere to the inner wall of the pipe to form a solidified layer or a sticky layer, which will reduce the effective cross-sectional area of ​​the pipe, resulting in increased fluid transport pressure, decreased flow rate, and even local blockage. Utility Model Content

[0004] The purpose of this invention is to solve the problem that a certain amount of grout easily remains inside the grouting pipe, which continuously adheres to the inner wall of the pipe to form a solidified layer or a viscous layer, resulting in a reduction in the effective cross-sectional area of ​​the pipe and an increase in fluid transport pressure and a decrease in flow rate. Therefore, a grouting device for road and bridge construction is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a grouting device for road and bridge construction, comprising a grouting chamber, an output port at one end of the grouting chamber, a grouting pipe movably connected inside the output port, a transfer frame fixedly connected to the outside of the grouting pipe, an adjustment chamber fixedly connected to the other end of the transfer frame, an adjustment rod fixedly connected to one side of the grouting chamber, and one end of the adjustment rod movably penetrating through the interior of the adjustment chamber.

[0006] Preferably, an installation groove is provided on the outer side of one end of the grouting pipe, and a sealing ring is movably sleeved on the outer side of the installation groove.

[0007] Preferably, the regulating chamber includes a chamber body, the chamber body has an regulating hole inside, and a positioning bolt is threaded into the regulating hole.

[0008] Preferably, one end of the adjusting rod has a threaded hole, and one end of the positioning bolt is threaded into the inside of the threaded hole.

[0009] Preferably, a retaining ring is fixedly connected to one end of the adjusting rod.

[0010] Preferably, the two sides of the slurry supply chamber are symmetrically fixedly connected with transition angle irons, and one end of the transition angle irons is provided with an installation hole.

[0011] Preferably, the other end of the slurry supply chamber is fixedly connected to a slurry supply pipe.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, under the transmission and coordination of the adapter frame, one end of the grouting pipe slides smoothly out of the output port; after the grouting pipe is partially extended, the adjustment chamber is rotated, and the torque transmission of the adapter frame drives the grouting pipe to rotate synchronously, adjusting it to an unobstructed open working area. The operator thoroughly cleans the inner wall of the grouting pipe to remove residual grout, ensuring that the inner wall of the pipe meets the cleanliness standard, and avoiding the problem of reduced effective cross-sectional area of ​​the pipe due to grout adhesion.

[0013] 2. In this utility model, the positioning bolt is rotated to achieve the following: The operator rotates the positioning bolt in a preset direction, causing one end of the positioning bolt to completely disengage from the preset threaded hole on the adjusting rod, until the positioning bolt is disengaged from the threaded hole. At this time, the locking constraint between the adjusting chamber and the adjusting rod is completely released, and the adjusting chamber can freely slide up and down vertically on the outside of the adjusting rod, while also freely rotating around the axis of the adjusting rod, providing operating conditions for subsequent movement of the adjusting chamber and adjustment of the grouting pipe position.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a grouting device for road and bridge construction, including a grouting chamber 1. One end of the grouting chamber 1 has an output port 11, and the output port 11 is movably connected to a grouting pipe 2. A transition frame 3 is fixedly connected to the outside of the grouting pipe 2, and an adjustment chamber 4 is fixedly connected to the other end of the transition frame 3. An adjustment rod 5 is fixedly connected to one side of the grouting chamber 1, and one end of the adjustment rod 5 movably passes through the inside of the adjustment chamber 4. An installation groove 21 is opened on the outside of one end of the grouting pipe 2, and a sealing ring 22 is movably sleeved on the outside of the installation groove 21. Adapter angle irons 12 are symmetrically fixedly connected to both sides of the grouting chamber 1. An installation hole 121 is opened at one end of the adapter angle iron 12, and a grouting pipe 13 is fixedly connected to the other end of the grouting chamber 1.

[0019] The specific settings and functions of this embodiment are described below. When cleaning the inner wall of the grouting pipe 2 is required, the locking constraint between the regulating chamber 4 and the regulating rod 5 is first released. Then, the regulating chamber 4 is moved vertically downwards. Under the transmission and coordination of the adapter frame 3, one end of the grouting pipe 2 slides smoothly out of the output port 11. After the grouting pipe 2 is partially extended, the regulating chamber 4 is rotated. Through the torque transmission of the adapter frame 3, the grouting pipe 2 is rotated synchronously, adjusting it to an unobstructed open working area. The operator needs to use appropriate professional cleaning equipment to thoroughly clean the inner wall of the grouting pipe 2, remove residual grout, and ensure that the inner wall of the pipe meets the cleanliness standard to avoid the problem of reduced effective cross-sectional area of ​​the pipe due to grout adhesion.

[0020] When carrying out grouting operations, the pump system is started, and the pump steadily delivers the grout to the grouting chamber 1 through the grouting supply pipe 13. The grout entering the grouting chamber 1 flows precisely into the grouting pipe 2 from the output port 11 along the preset flow channel. Since one end of the grouting pipe 2 has been pre-positioned at the designated position in the road crack, the grout can be directly injected into the road crack through the delivery of the grouting pipe 2, so as to achieve precise filling of the road crack by the grout.

[0021] To ensure the stability of the grout supply chamber 1 during operation, the operator can use bolts to connect with the pre-set mounting holes 121 on the adapter angle iron 12. Through the tightening action of the bolts, the grout supply chamber 1 is firmly installed in the designated installation area, ensuring that it maintains structural stability during grouting and related operations, and avoiding the impact of displacement on the accuracy of the operation.

[0022] Example 2: Figure 1 - Figure 4 As shown, the grouting device for road and bridge construction of this utility model includes a grouting chamber 1. One end of the grouting chamber 1 has an output port 11. The output port 11 is movably connected to a grouting pipe 2. A transition frame 3 is fixedly connected to the outside of the grouting pipe 2. The other end of the transition frame 3 is fixedly connected to an adjusting chamber 4. An adjusting rod 5 is fixedly connected to one side of the grouting chamber 1. One end of the adjusting rod 5 movably passes through the interior of the adjusting chamber 4. The adjusting chamber 4 includes a chamber body 40. An adjusting hole 41 is opened inside the chamber body 40. A positioning bolt 42 is threadedly connected inside the adjusting hole 41. One end of the adjusting rod 5 has a threaded hole 51. One end of the positioning bolt 42 is threadedly connected inside the threaded hole 51. A retaining ring 52 is fixedly connected to one end of the adjusting rod 5.

[0023] The overall effect of this embodiment is that when performing the cleaning operation on the inner wall of the grouting pipe 2 and needing to release the engagement constraint between the regulating chamber 4 and the regulating rod 5, this is achieved by rotating the positioning bolt 42: the operator rotates the positioning bolt 42 in a preset direction, causing one end of the positioning bolt 42 to completely disengage from the preset threaded hole 51 on the regulating rod 5, until the positioning bolt 42 and the threaded hole 51 are disengaged. At this time, the engagement constraint between the regulating chamber 4 and the regulating rod 5 is completely released, and the regulating chamber 4 can freely slide up and down in the vertical direction on the outside of the regulating rod 5, while also freely rotating around the axis of the regulating rod 5, providing operating conditions for the subsequent movement of the regulating chamber 4 and the position adjustment of the grouting pipe 2. In addition, the retaining ring 52 configured on the adjusting rod 5 has a limiting support function, which can provide stable support for the bottom end of the adjusting chamber 4, effectively limiting the downward movement of the adjusting chamber 4 along the axial direction of the adjusting rod 5, preventing the adjusting chamber 4 from sliding off the bottom end of the adjusting rod 5 during the lifting and sliding process, and ensuring the structural stability and safety during operation.

[0024] The usage and working principle of this device are as follows: When cleaning the inner wall of the grouting pipe 2 is required, firstly, release the locking constraint between the regulating chamber 4 and the regulating rod 5; then, move the regulating chamber 4 vertically downwards, and under the transmission and coordination of the adapter frame 3, allow one end of the grouting pipe 2 to slide smoothly out from the output port 11; after the grouting pipe 2 is partially extended, rotate the regulating chamber 4, and through the torque transmission of the adapter frame 3, drive the grouting pipe 2 to rotate synchronously, adjusting it to an unobstructed open working area; the operator needs to use appropriate professional cleaning equipment to thoroughly clean the inner wall of the grouting pipe 2 and remove any residual grout.

[0025] When carrying out grouting operations, the pump system is started, and the pump steadily delivers the grout to the grouting chamber 1 through the grouting supply pipe 13. The grout entering the grouting chamber 1 flows precisely into the grouting pipe 2 from the output port 11 along the preset flow channel. Since one end of the grouting pipe 2 has been pre-positioned at the designated position in the road crack, the grout can be directly injected into the road crack through the delivery of the grouting pipe 2, so as to achieve precise filling of the road crack by the grout.

[0026] To ensure the stability of the slurry supply chamber 1 during operation, the operator can use bolts to connect with the pre-set mounting holes 121 on the adapter angle iron 12. Through the tightening action of the bolts, the slurry supply chamber 1 can be firmly installed in the designated installation area.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
