Description

Technical Field

[0001] This invention relates to a grouting perforated pipe structure, grouting equipment, and grouting method. It is applicable to the field of grouting technology. Background Technology

[0002] Grouting is an engineering technique that uses specialized equipment to mix fluid and cementitious grout materials, such as cement grout or chemical grout, in a certain proportion, and then injects them into ground fissures, pores, or building structure gaps through drilling or pre-embedded pipelines under certain pressure. This allows the grout to diffuse, solidify, and harden, thereby reinforcing the foundation, blocking water veins, filling voids, and enhancing the overall structural integrity.

[0003] Grouting equipment refers to a systematic construction equipment that integrates functional modules such as grout preparation, transportation, injection, monitoring and control in geotechnical engineering projects such as foundation treatment, tunnel excavation, mining, and water conservancy and hydropower. It uses a high-pressure pumping system to precisely inject specific grouts such as cement grout, chemical grout, and bentonite grout into the strata or structural voids.

[0004] However, when the grouting pipe is inserted into the deep hole drilled by the drilling rig, and the double-plug grouting device is lowered to begin injecting grout into the grouting pipe, the rubber cap inside the through hole on the outer surface of the grouting pipe will be pushed up under pressure. As the grout accumulates and the pressure reaches a certain level, the rubber cap on the outer surface of the grouting pipe, corresponding to the position of the double-plug grouting device, will expand, and the grout will diffuse and seep into the surrounding soil. Although this method can prevent the grout from flowing up and down inside the grouting pipe, the grout that seeps into the soil may flow upward along the soil and enter the grouting through hole above it, solidifying and fixing the inner rubber cap in the through hole, causing the through hole to be sealed and unable to expand. This may eventually lead to the appearance of a grouting blind zone. In addition, the pressure sensors on some existing grouting equipment are generally installed inside the grouting pipeline. When monitoring pressure at this location, the friction resistance and local losses must be deducted, and the accuracy of the values ​​detected by the pressure sensor operating at this location is low. Summary of the Invention

The third drive mechanism is mounted on the mounting base, and the movable seat is connected to the third drive mechanism. The third drive mechanism can drive the movable seat to move within the first mounting slot. The control terminal is connected to the first drive mechanism, the second drive mechanism, and the third drive mechanism. The control terminal can control the operation of the first drive mechanism, the second drive mechanism, and the third drive mechanism.

[0007] The push head has an external thread on its side wall, and the second mounting groove has an internal thread that mates with the external thread of the push head on its inner wall. The push head has a mounting hole at its tail end that runs along its length. The mounting hole has a second sliding groove on its side wall that runs along its length. A slidable transmission rod is installed in the mounting hole. A second slider that slides with the second sliding groove is installed on the side wall of the transmission rod. The first drive mechanism has a drive motor installed in the movable seat. The drive motor and the transmission rod are connected by a gear set.

[0008] The gear set has a first gear mounted on the output shaft of the drive motor, a rotatable gear shaft mounted in the movable seat, a second gear meshing with the first gear mounted on the gear shaft, a transmission shaft mounted at the end of the transmission rod, a first bevel gear mounted on the transmission shaft, a rotatable internal gear ring mounted in the movable seat, a second bevel gear fitted around the internal gear ring, and a third gear mounted on the gear shaft, the third gear meshing with the internal gear ring, and the first bevel gear meshing with the second bevel gear.

[0009] A fixing block is installed on the grouting pipe, and a third sliding groove is formed on the side wall of the third mounting groove along the length of the third mounting groove. A third slider that slides in cooperation with the third sliding groove is installed on the fixing block. The second drive mechanism has a telescopic cylinder installed in the movable seat, and the fixing block is connected to the end of the telescopic cylinder.

[0010] The telescopic cylinder is arranged along the length direction perpendicular to the third mounting groove. A push block is installed at the end of the telescopic cylinder. A ramp is made on the push block at the end facing the grouting pipe. A fourth sliding groove is arranged along the ramp. A fourth slider that slides in cooperation with the fourth sliding groove is installed on the fixed block.

[0011] The third drive mechanism has an electric winch mounted on a mounting base, on which a steel wire rope is wound up, and the end of the steel wire rope is connected to a pull ring on a movable base.

[0012] At least one set of grouting holes is provided on the side wall of the main body of the perforated pipe along the length of the main body of the perforated pipe. Each set of grouting holes has at least one grouting hole along the circumferential direction of the main body of the perforated pipe. A grout tank is provided on the mounting base, and the grout tank is connected to each grouting pipe through a grout delivery pipe.

[0013] A through hole is made on the side wall of the grouting pipe, and a pressure sensor is installed in the through hole of the grouting pipe. An electric valve is installed between the grout tank and the grout delivery pipe. Both the pressure sensor and the electric valve are connected to the control terminal.

[0014] A grouting device, using the above-mentioned grouting perforated pipe structure, is characterized by having a grout storage chamber containing grout, a grouting pump installed in the grout storage chamber, the outlet end of the grouting pump being connected to a grout tank on the mounting base via a connecting pipe, and the grouting pump being communicatively connected to a control terminal.

[0015] A grouting method using grouting equipment, employing the aforementioned grouting equipment: Install the main body of the perforated pipe inside the borehole in the grouting soil layer; The control terminal controls the third drive mechanism to operate and drives the movable seat to move within the first mounting groove of the flower pipe body to the position where the push head on the movable seat corresponds to the grouting hole. The control terminal controls the first drive mechanism to operate and drives the push head to extend and retract. As the push head moves outward from the moving seat, the push head will push open the rubber cap at the grouting hole. The control terminal controls the second drive mechanism to operate and drives the grouting pipe to extend. The grouting pipe passes through the grouting hole and extends into the grouting soil layer. The control terminal controls the operation of the grouting pump, which injects the grout from the storage chamber into the grouting soil layer through the connecting pipe, grout tank, delivery pipe, and injection pipe. After the grouting pipe is extended into the grouting soil layer and grouting is completed for a period of time, the grout in the grouting soil layer completes the initial setting. The control terminal controls the second drive mechanism to operate and drive the grouting pipe to retract. The control terminal controls the third drive mechanism to operate and drive the moving seat to move upward to the position corresponding to the previous grouting hole and complete the above grouting. During the grouting process, the pressure sensor inside the grouting pipe monitors the pressure information of the grouting slurry. The pressure information is sent to the control terminal, which adjusts the electric valve based on the rise and fall of the acquired pressure information.

[0016] The beneficial effects of this invention are as follows: After the main body of the perforated pipe is inserted into the borehole of the grouting soil layer, the third drive mechanism is controlled by the control terminal to move the moving seat inside the perforated pipe body to the position where the push head on the moving seat corresponds to the grouting hole on the perforated pipe body. At this time, the first drive mechanism is controlled by the control terminal, and the push head will move telescopically under the action of the first drive mechanism. During the process of the push head moving out of the moving seat, the push head will push open the rubber cap at the grouting hole. The second drive mechanism is controlled by the control terminal, and the grouting pipe moves out of the moving seat under the action of the second drive mechanism, passes through the grouting hole on the perforated pipe body and extends into the grouting soil layer. At this time, by filling the grouting pipe with grout, the grout can be filled into the grouting soil layer, thus achieving precise positioning of the grouting part.

[0017] The present invention installs a pressure sensor in the through hole of the grouting pipe and sets an electric valve between the grout tank and the grout delivery pipe, so as to determine the grouting status of the grouting soil layer 14 based on the pressure information of the grout in the through hole of the grouting pipe obtained by the pressure sensor, and thus adjust the opening and closing degree of the electric valve.

[0030] Example 1 is a grouting perforated pipe structure. In this example, it has the following features: The main body of the flower pipe 1 has a first mounting groove 1-1 arranged along the length of the main body of the flower pipe 1 inside. The side wall of the first mounting groove 1-1 of the main body of the flower pipe 1 has a first sliding groove arranged along the length of the main body of the flower pipe 1. The side wall of the main body of the flower pipe 1 has a grouting hole 1-2. A rubber cap 2 is fastened at the grouting hole 1-2. The top of the main body of the flower pipe 1 has a mounting seat 9. The movable seat 3 is installed in the first mounting groove 1-1 of the flower tube body 1, and a first slider that slides in cooperation with the first sliding groove is installed on the movable seat 3. The push head 4 has a second mounting groove 3-1 on the side wall of the movable seat 3 at a position corresponding to the grouting hole 1-2. The push head 4 is slidably mounted in the second mounting groove 3-1. A first driving mechanism 5 is provided on the movable seat 3. When the grouting pipe 6 moves with the movable seat 3 to the position corresponding to the grouting hole 1-2, the first driving mechanism 5 can drive the push head 4 to move along the length direction of the second mounting groove 3-1 to move out of the grouting hole 1-2 and push up the rubber cap 2 at the grouting hole 1-2. The grouting pipe 6 has a third mounting groove 3-2 on the side wall of the movable seat 3 at a position corresponding to the grouting hole 1-2. The grouting pipe 6 is slidably mounted in the third mounting groove 3-2. A second driving mechanism 7 is provided on the movable seat 3. When the grouting pipe 6 moves with the movable seat 3 to the position corresponding to the grouting hole 1-2, the second driving mechanism 7 can drive the grouting pipe 6 to move along the length direction of the third mounting groove 3-2 and extend out of the grouting hole 1-2. The third drive mechanism 8 is mounted on the mounting base 9, and the movable base 3 is connected to the third drive mechanism 8. The third drive mechanism 8 can drive the movable base 3 to move within the first mounting slot 1-1. The control terminal 13 is connected to the first drive mechanism 5, the second drive mechanism 7, and the third drive mechanism 8. The control terminal 13 can control the operation of the first drive mechanism 5, the second drive mechanism 7, and the third drive mechanism 8. Thus, after the main body 1 of the perforated pipe is inserted into the borehole of the grouting soil layer 14, the third drive mechanism 8 is controlled by the control terminal 13 to move the moving seat 3 within the main body 1 to the position corresponding to the push head 4 on the moving seat 3 and the grouting hole 1-2 on the main body 1 of the perforated pipe. At this time, the first drive mechanism 5 is controlled by the control terminal 13 to operate, and the push head 4 will move telescopically under the action of the first drive mechanism 5. During the process of the push head 4 moving out of the moving seat 3, the push head 4 will push open the rubber cap 2 at the grouting hole 1-2. The control terminal 13 controls the second drive mechanism 7 to operate, and the grouting pipe 6 moves out of the moving seat 3 under the action of the second drive mechanism 7, passes through the grouting hole 1-2 on the main body 1 of the perforated pipe and extends into the grouting soil layer 14. At this time, the grout can be filled into the grouting soil layer 14 by filling the grouting pipe 6.

[0031] In this embodiment, at least one set of grouting holes 1-2 is provided on the side wall of the main body 1 along the length of the main body 1. Each set of grouting holes 1-2 has at least one grouting hole 1-2 arranged along the circumferential direction of the main body 1. A grout tank 9-1 is provided on the mounting base 9, and the grout tank 9-1 is connected to each grouting pipe 6 through a grout delivery pipe 9-2. In this way, by moving the movable base 3 to the position corresponding to each set of grouting holes 1-2, it is easy to adjust the grouting position; by arranging the grouting holes 1-2 along the circumferential direction of the main body 1, it is easy to uniformly inject grout into the grouting soil layer 14 around the main body 1.

[0032] In this embodiment, a through hole 6-1 is formed on the side wall of the grouting pipe 6. A pressure sensor 6-2 is installed in the through hole 6-1 of the grouting pipe 6. An electric valve 9-3 is provided between the grout tank 9-1 and the grout delivery pipe 9-2. Both the pressure sensor 6-2 and the electric valve 9-3 are communicatively connected to the control terminal 13. Thus, during the grouting process, the pressure information of the grout is monitored by the pressure sensor 6-2 set on the through hole 6-1 of the grouting pipe 6 and sent to the control terminal 13, thereby adjusting the opening and closing degree of the electric valve 9-3. If the pressure information obtained is low, it indicates that there are many voids in the grouting soil layer 14 located here, and the grouting slurry can flow smoothly into the interior of the grouting soil layer 14. At this time, the discharge speed of the grouting slurry is accelerated by the corresponding electric valve 9-3 to fill the many voids in this location. If the pressure information obtained is high, it indicates that there are few voids in the grouting soil layer 14 located here, and the grouting slurry needs a certain pressure to flow into the interior of the grouting soil layer 14. At this time, the discharge speed of the grouting slurry is slowed down by the corresponding electric valve 9-3.

[0033] Example 2 is a grouting pipe structure. Based on Example 1, in this example, the push head 4 has an external thread on its side wall, and the second mounting groove 3-1 has an internal thread that mates with the external thread of the push head 4. The push head 4 has a mounting hole at its tail, extending along its length. A second sliding groove, extending along the length of the mounting hole, is formed on the side wall of the mounting hole. A slidable transmission rod 4-1 is installed in the mounting hole, and a second slider, slidably engaging with the second sliding groove, is installed on the side wall of the transmission rod 4-1. The first drive mechanism 5 has a drive motor 5-1 installed in the movable seat 3, and the drive motor 5-1 is connected to the transmission rod 4-1 via a gear set. Thus, when the control terminal 13 drives the first drive mechanism 5, the gear set can rotate the transmission rod 4-1. The sliding engagement between the second slider on the transmission rod 4-1 and the second sliding groove on the push head 4, and the threaded engagement between the push head 4 and the second mounting groove 3-1, allows the push head 4 to move along the length of the second mounting groove 3-1.

[0034] In this embodiment, the gear set has a first gear 5-3 mounted on the output shaft 5-2 of the drive motor 5-1, a rotatable gear shaft 5-4 mounted in the movable seat 3, a second gear 5-5 mounted on the gear shaft 5-4 that meshes with the first gear 5-3, a transmission shaft 5-7 mounted at the end of the transmission rod 4-1, a first bevel gear 5-9 mounted on the transmission shaft 5-7, a rotatable internal gear ring 5-8 mounted in the movable seat 3, a second bevel gear 5-10 fitted around the internal gear ring 5-8, a third gear 5-6 mounted on the gear shaft 5-4, the third gear 5-6 meshing with the internal gear ring 5-8, and the first bevel gear 5-9 meshing with the second bevel gear 5-10.

[0035] Example 3 is a grouting pipe structure. Based on Example 1, in this example, a fixing block 6-3 is installed on the grouting pipe 6, and a third sliding groove 7-3 is formed on the side wall of the third mounting groove 3-2 along the length of the third mounting groove 3-2. A third slider 6-4 is installed on the fixing block 6-3 and slides in cooperation with the third sliding groove 7-3. The second drive mechanism 7 has a telescopic cylinder 7-1 installed in the movable seat 3, and the fixing block 6-3 is connected to the end of the telescopic cylinder 7-1. Thus, when the control terminal 13 drives the second drive mechanism 7, the sliding cooperation between the third slider 6-4 on the fixing block 6-3 and the third sliding groove 7-3 in the third mounting groove 3-2 drives the grouting pipe 6 to move along the length of the third mounting groove 3-2.

[0036] In this embodiment, the telescopic cylinder 7-1 is arranged along the length direction perpendicular to the third mounting groove 3-2. A pusher block 7-2 is installed at the end of the telescopic cylinder 7-1. A ramp is formed on the end of the pusher block 7-2 facing the grouting pipe 6. A fourth sliding groove is arranged along the ramp. A fourth slider 6-5 that slides with the fourth sliding groove is installed on the fixing block 6-3. Thus, the telescopic cylinder 7-1 is arranged in the axial direction of the perforated pipe body 1, and the grouting pipe 6 is arranged on the cross-section of the perforated pipe body 1. When the telescopic cylinder 7-1 is running, it drives the pusher block 7-2 to move along the axial direction of the perforated pipe body 1. Under the sliding action of the fourth sliding groove on the ramp of the pusher block 7-2 and the fourth slider 6-5 on the fixing block 6-3, the grouting pipe 6 is moved on the cross-section of the perforated pipe body 1.

A steel wire rope 8-1 is wound onto the electric winch, and the end of the steel wire rope 8-1 is connected to a pull ring 8-2 on the movable base 3. Thus, when the control terminal 13 controls the operation of the electric winch, the steel wire rope 8-1 is wound onto the electric winch. During the winding process, the steel wire rope 8-1 pulls the movable base 3 to move within the perforated pipe body 1. The sliding engagement between the first slider on the movable base 3 and the first groove in the first mounting groove 1-1 of the perforated pipe body 1 provides good guidance for the movement of the movable base 3.

The grouting pump 11 is also connected to a control terminal 13. Thus, when the control terminal 13 controls the grouting pump 11 to operate, the grout in the storage chamber 12 is transported through the connecting pipe 10, the grout tank 9-1, and the grout delivery pipe 9-2 to the grouting pipe 6, and finally injected into the grouting soil layer 14.

[0047] The grouting method in this embodiment is as follows: Install the main body 1 of the perforated pipe into the borehole of the grouting soil layer 14; The control terminal 13 controls the third drive mechanism 8 to run and drive the movable seat 3 to move within the first mounting groove 1-1 of the flower pipe body 1 to the position where the push head 4 on the movable seat 3 corresponds to the grouting hole 1-2. The control terminal 13 controls the first drive mechanism 5 to run and drive the push head 4 to move telescopically. During the process of the push head 4 moving outward from the moving seat 3, the push head 4 will push open the rubber cap 2 at the grouting hole 1-2. The control terminal 13 controls the second drive mechanism 7 to operate and drives the grouting pipe 6 to extend. The grouting pipe 6 passes through the grouting hole 1-2 and extends into the grouting soil layer 14. The control terminal 13 controls the operation of the grouting pump 11 to inject the grout in the grout storage chamber 12 into the grouting soil layer 14 through the connecting pipe 10, grout tank 9-1, grout delivery pipe 9-2, grouting pipe 6, and finally into the grouting soil layer 14. After the grouting pipe 6 is extended into the grouting soil layer 14 and grouting is completed for a period of time, the grout in the grouting soil layer 14 completes its initial setting. The control terminal 13 controls the second drive mechanism 7 to operate and drive the grouting pipe 6 to retract. The control terminal 13 also controls the third drive mechanism 8 to operate and drive the moving seat 3 to move upward to the position corresponding to the grouting hole 1-2 of the upper layer, thus completing the above grouting. After the lower layer of grout has completed its initial setting, when the moving seat 3 is moved upward and the upper layer of grout is injected, the upper layer of grout will not penetrate into the lower layer of grout and will seep into the perforated pipe body 1 through the grouting hole 1-2 at the lower layer of grout. During the grouting process, the pressure sensor 6-2 inside the grouting pipe 6 through hole 6-1 monitors the pressure information of the grouting slurry. The pressure information is sent to the control terminal 13, and the control terminal 13 adjusts the electric valve 9-3 by adjusting the rise and fall of the acquired pressure information.
