Description

Technical Field

[0001] The invention relates to the technical field of foundation grouting deviation correction equipment, in particular to a grouting deviation correction device for a foundation in a narrow space. Background Art

[0002] Narrow space foundation correction refers to the correction and reinforcement measures taken when an existing narrow space foundation deviates from its vertical position for some reason and becomes tilted, seriously affecting its use, or even endangering the lives and property of residents and the safety of factory production, in order to restore its normal use function. It is necessary to use a grouting correction device to correct the tilted narrow space foundation. The foundation grouting correction device is a series of equipment used to correct the settlement, tilt or other structural problems of the building foundation through grouting technology. These devices mainly include grouting pumps, grouting drills, grouting pipelines and monitoring equipment.

[0003] When the existing foundation grouting correction device is used, a grouting hole is first drilled at a suitable position of the narrow space foundation, and a grouting pipe of suitable thickness is extended into the grouting hole, and an appropriate amount of cement slurry is injected into the narrow space foundation at the required tilted position, so that the grouting pipe position where the cement slurry needs to be injected into the narrow space foundation and the state parameters of the injected cement slurry are determined and accurate, and the grouting pipe is inserted into the grouting hole at the required position of the narrow space foundation and connected to the grouting pump. Since the output end of the grouting pipe directly outputs high-speed flowing cement slurry, it will directly impact the cement slurry in the grouting hole, which not only affects the correction operation of the foundation in the narrow space, but also causes the cement slurry around the foundation to impact the cement slurry under high-speed flow to arouse bubbles, which cannot be discharged from the cement slurry conveniently and quickly, thereby affecting the quality of the solidified cement slurry, and cannot accurately control the state parameters of the correction cement slurry injected into the narrow space foundation, thereby reducing the correction accuracy of the narrow space foundation and reducing the correction effect of the grouting correction device of the narrow space foundation.

[0042] The specific implementation of this embodiment is as follows: when it is necessary to use the grouting correction device to perform grouting correction operations on the deflected position of the foundation in a narrow space, the micro-grouting pump 11 of the grouting correction device is first manually transported to the deflected position of the foundation, and a grouting hole of a suitable depth is drilled at a suitable location at the deflected position of the foundation by a micro-grouting drill, and then the raw materials required for the cement slurry are manually transported to the mud mixing drum of the micro-grouting pump 11, so that the cement slurry required by the grouting correction device can be conveniently mixed, and the grouting pipe 17 can be installed into the inside of the output end sealing sleeve 16 of the handheld extension hose 15 by manually twisting the grouting pipe 17, so that the grouting pipe 17 can be inserted into the grouting hole by manually holding the handheld extension hose 15. The grouting pipe 17 is fixed in the hole, and the lower fixing flange 18 fixed outside the grouting pipe 17 can be in contact with the ground. The lower fixing flange 18 fixed outside the grouting pipe 17 can be connected to the ground through a fixed structure, and is also connected to the micro grouting pump 11, so that the grouting pipe 17 can be firmly fixed inside the grouting hole. Since there is no cement slurry in the grouting pipe 17, the driving blade 2103 cannot be rotated, so that the extension plate 2115 and the storage plate 2118 under the driving blade 2103 can be retracted into the grouting pipe 17. By controlling the power supply of the micro grouting pump 11, the micro grouting pump 11 can be used to drive the cement slurry in the mud mixing drum to be transported to the inside of the grouting hole through the telescopic tube 14, the handheld extension hose 15 and the grouting pipe 17.

The rotation of the rotating rod 2101 can make the centrifugal block 2110 on the rotating frame 2104 slide in a limited position. Since multiple pulling ropes 2108 are fixed outside the sliding ring 2107, the pulling ropes 2108 can slide in the two limiting blocks 2109 and the rotating frame 2104. The multiple centrifugal blocks 2110 can be conveniently moved by the rotating centrifugal force.

The tension spring 2106 that slides outside the rotating rod 2101 can be stretched by pulling the pulling rope 2108 until the centrifugal block 2110 can be moved to the position in contact with the limiting block 2109. Since the fixed movable rotating ring 2112 slides in the grouting pipe 17 under the pulling rope 2108, and the limiting sliding ring 2114 fixed by the movable rotating ring 2112 through multiple rotating springs 2113 rotates in the limiting sliding groove 2121 opened on the gear ring 2120, not only the movable rotating ring 2112 can be limited,It is also possible to conveniently extend the multiple extension plates 2115 fixed in the mobile swivel 2112 to the bottom end of the grouting pipe 17, and by fixing the compression spring 2117 between the receiving groove 2116 and the receiving plate 2118, the elastic force in the compression spring 2117 can be released, so that the receiving plate 2118 can rotate along the hinge axis hinged to the receiving groove 2116 until the multiple receiving plates 2118 can be unfolded, and the stirring plate 2119 hinged under the receiving plate 2118 can be unfolded, so that the cement slurry in the grouting hole can be conveniently stirred by the rotating extension plate 2115, the receiving plate 2118 and the stirring plate 2119 to discharge the bubbles in the cement slurry in the grouting hole, so as to conveniently control the volume of the cement slurry injected into the grouting hole, and also improve the stability of the solidified cement slurry in correcting the foundation, thereby improving the correction accuracy of the foundation, and improving the correction effect of the grouting correction device for the narrow space foundation.
