Description

Technical Field

[0001] The utility model relates to the technical field of foundation grouting jacking and tilt correction, in particular to a capsule type grouting jacking and tilt correction device. Background Art

[0002] The common method of foundation grouting jacking and tilt correction is to inject cement or chemical slurry at high pressure into the foundation soil layer on the side of the building with larger original settlement to squeeze the foundation soil, and at the same time play the role of tilt correction and reinforcement. However, during the grouting process, excess pore water pressure is generated. The dissipation of pore water pressure causes the soil to consolidate and the slurry to condense. The consolidation of the soil layer is likely to cause the settlement and displacement of the soil. Therefore, negative additional deformation may occur during the jacking process. Moreover, for the tilt of the building caused by uneven foundation, the injected slurry may not be able to enter the foundation soil evenly, resulting in uneven foundation lifting and failure to achieve the purpose of accurate jacking.

[0003] The patent name is "CN219471043U", which is published as: A bladder-type grouting lifting and deviation correction device. The public document solves the above problems, but the shortcomings in the public document are: when the bladder bag and the first sealing ring are inserted into the pile hole through the through hole, the bladder bag and the first sealing ring are completely exposed to the outside world, and the bladder bag and the first sealing ring will collide with the through hole and the inner wall of the pile hole to produce friction, which will cause wear on the bladder bag and the sealing ring. Although the public document also proposes: when the grouting volume far exceeds the design estimate, or the grouting pressure cannot meet the design requirements, the slurry ratio should be adjusted, or the grouting should be intermittently injected into the bladder bag to wait for the damaged part of the bladder bag to be blocked by the solidified slurry, and then the slurry is injected into the bladder bag. However, the above method of repairing the bladder bag requires waiting for the slurry to solidify, which takes time and reduces the work efficiency of the staff. Based on this, the utility model designs a bladder-type grouting lifting and deviation correction device to solve the above problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the device consists of a discharge assembly consisting of a catheter 1, a connecting tube 2 with internal threads of the catheter 1, and an airbag 3 sealed and fixedly sleeved on the bottom of the connecting tube 2. The catheter 1 is sleeved on the outside and a baffle 4 is sleeved on the lower end, and an annular groove 5 is integrally arranged around the outside of the baffle 4, an air cushion 6 is fixedly arranged around the annular groove 5, and a driving assembly 7 is arranged on the top of the baffle 4 to control the baffle 4 to move along the longitudinal direction of the catheter 1. The driving assembly 7 includes a guide groove 701 integrally arranged on the top of the baffle 4, and a connecting rod 702 is slidably connected inside the guide groove 701. A mounting sleeve 703 fixed on the top of the connecting rod 702 is threadedly sleeved on the catheter 1, an exhaust pipe 704 is fixedly penetrated on one side of the top of the mounting sleeve 703, and the other end of the exhaust pipe 704 is sealed and fixedly penetrated through the baffle 4 and the air cushion 6 in turn.

[0029] The staff will hold the upper end of the catheter 1 to insert the connecting tube 2, the airbag 3 and the baffle 4 from the through hole into the pile hole. The catheter 1 covers the airbag 3 and the air cushion 6 in the annular groove 5 to prevent the airbag 3 and the air cushion 6 from rubbing against the inner wall of the through hole and the pile hole during the insertion process, thereby protecting the airbag 3 and the air cushion 6. After the insertion is completed, the staff holds the connecting tube 2 with one hand and rotates the catheter 1 with the other hand. Through the threaded transmission of the catheter 1 and the connecting tube 2, the catheter 1 is moved along the connecting tube 2. The direction of the connecting pipe 2 is rotated and moved upward, so that the catheter 1 and the airbag 3 are in a misaligned state, that is, the airbag 3 is exposed inside the pile hole. The staff then connects the external inflation device with the exhaust pipe 704. By using the inflation device, the inflation gas is injected into the air cushion 6 from the exhaust pipe 704, so that the air cushion 6 expands. The expanded air cushion 6 fits tightly with the inner wall of the pile hole, thereby isolating the airbag 3 from the outside world, and then injecting slurry into the airbag 3 from the connecting pipe 2, so that the expanded airbag 3 supports the building, that is, the building is corrected.

[0030] Example 2

[0031] like Figure 1 , Figure 2, Figure 4 As shown, the catheter 1 is sleeved on the airbag 3, and a number of balls 8 are connected around the lower end of the inner part of the catheter 1, and the balls 8 and the airbag 3 are fitted together. The cross-sections of the guide groove 701 and the connecting rod 702 are both T-shaped. The connecting rod 702 can be prevented from escaping from the guide groove 701 through the T-shaped clamping design of the guide groove 701 and the connecting rod 702. The center of the annular groove 5 is concentric with the center of the baffle 4, and the center of the annular groove 5 is concentric with the center of the guide groove 701. The exhaust pipe 704 is made of hard material, and a valve 9 is rotated through the outside of the exhaust pipe 704. A scale 10 is integrally provided on the upper end of the outer wall of the catheter 1, and the left and right sides of the middle end of the inner part of the catheter 1 are Limiting grooves 11 are integrally arranged on both sides, and the limiting grooves 11 of the two pieces are in a parallel design state. Slide blocks 12 are fixedly arranged on the left and right sides of the inside of the baffle 4, and the slide blocks 12 are embedded in the limiting grooves 11, and the slide blocks 12 are longitudinally slidably connected to the limiting grooves 11. A retaining ring 13 is fixedly sleeved on the upper end of the outer side of the connecting pipe 2, and the center of the retaining ring 13 is concentric with the center of the connecting pipe 2. The connecting rods 702 of the two pieces are in a parallel design state, thereby ensuring the stability of the connecting rod 702 driving the baffle 4 to move along the longitudinal direction of the catheter 1. The depth of the annular groove 5 is greater than the thickness of the air cushion 6 in the compressed state, thereby preventing the compressed air cushion 6 from leaking out of the annular groove 5.

[0032] According to the operation mode in Example 1, when the catheter 1 rotates forward, the catheter 1 will drive the baffle 4 to move together with the connecting tube 2, and the catheter 1 drives the ball 8 and the airbag 3 to be in a state of rolling friction, so as to prevent the displacement of the catheter 1 from scratching the airbag 3, until the catheter 1 and the retaining ring 13 contact each other, at this time it means that the airbag 3 as a whole has been fully exposed inside the pile hole, and at the same time, the distance between the baffle 4 and the airbag 3 will change. When the airbag 3 is exposed inside the pile hole, the staff first rotates the installation sleeve 703 so that the installation sleeve 703 drives the connecting rod 702 together with the baffle 4 and the slider 12 to move along the direction of the limit groove 11, until the installation sleeve 703 moves to the value on the scale 10 that meets the staff's needs, at this time it means that the distance between the baffle 4 and the airbag 3 has been adjusted to within the range required by the staff, and then the air cushion 6 is inflated in sequence, and after the inflation is completed, the valve 9 is closed, and then the slurry is poured into the airbag 3.
