Detailed Description

The present application is described in further detail below with reference to figures 1-3.

Referring to fig. 1-2, the application discloses high accuracy pile foundation settlement detection ruler, including main scale 1, one side cover of main scale 1 is established and sliding connection has slide 2, one side fixed connection of slide 2 has the sighting rod 3 of level setting, and vertical setting's spout 13 is all seted up at the front portion and the back of main scale 1, and slide 2 is close to the lateral wall fixedly connected with slider 23 of spout 13, and slider 23 sliding connection is in spout 13. Through the mutual cooperation between the sliding block 23 and the sliding chute 13, the sliding base 2 and the mark post 3 can stably slide in the vertical direction. One side of the sliding seat 2 is penetrated and connected with a locking screw rod 4 in a threaded manner, and the height of the mark post 3 can be fixed by screwing the locking screw rod 4.

Referring to fig. 1-2, the front surface of the main scale 1 is provided with scale values 11, and one side of the slide base 2 away from the marker post 3 is fixedly connected with a pointer 21. Examine time measuring and vertically place main scale 1 in one side of pile foundation, not hard up locking screw 4 back gliding sliding base 2, paste mutually up to the last edge of slide 2 and pile foundation, screw up locking screw 4 and carry out the record to the directional scale of pointer 21, treat the pile foundation and subside the back, become flexible locking screw 4 once more, and the gliding slide 2 pastes mutually up to the last edge of slide 2 and pile foundation, the registration of twice records around is the settlement depth of pile foundation promptly by subtraction.

Wherein, the top fixedly connected with bubble spirit level 31 of sighting rod 3, bubble spirit level 31 is horizontal setting. The bubble level gauge 31 can be used for conveniently observing whether the marker post 3 is horizontal or not by a detection person. The pointer 21 is located on the side of the slide 2 close to the scale value 11 and the pointer 21 points horizontally to the scale value 11. And the operator can conveniently and visually read the scale value 11 pointed by the pointer 21.

Referring to fig. 2, one side of the main scale 1 is fixedly connected with a fixed sanding bar 12, a strip-shaped groove 22 is formed in a side wall of the sliding base 2 close to the fixed sanding bar 12, a sanding block 41 is slidably connected in the strip-shaped groove 22, and one end of the locking screw 4 extends into the strip-shaped groove 22 and is rotatably connected with the sanding block 41. The locking screw 4 is rotated to enable the sanding block 41 to be tightly pressed on the surface of the fixed sanding strip 12, the position of the sliding seat 2 can be well fixed by utilizing the friction force between the sanding block 41 and the fixed sanding strip 12, and the sliding seat 2 and the main ruler 1 are prevented from sliding relatively. A space is left between the fixed sanding strip 12 and the sliding seat 2. Since the sliding base 2 is not in contact with the fixed abrasive strip 12, the fixed abrasive strip 12 does not obstruct the sliding of the sliding base 2.

Referring to fig. 1 and 3, a bottom plate 5 is disposed at the bottom of the main scale 1, and the main scale 1 is fixedly connected to the top of the bottom plate 5 and perpendicular to the bottom plate 5. The bottom plate 5 can support the main scale 1, so that the main scale 1 is more stable when placed on the ground, and the shaking condition is not easy to occur.

In addition, the inside that bottom plate 5 is close to the four corners is worn to establish and threaded connection has the support screw 6 of vertical setting, and the bottom of support screw 6 is rotated and is connected with the backup pad 61 that supports bottom plate 5, rotates the distance between the adjustable backup pad 61 of support screw 6 and the bottom plate 5, and the top fixedly connected with of support screw 6 makes things convenient for the measurement personnel to carry out pivoted knob 62 to support screw 6. Can carry out the leveling to bottom plate 5 through four supporting screw 6 and backup pad 61, cooperate bubble spirit level 31 again to make main scale 1 be in vertical state, guaranteed that sighting rod 3 is the enterprising line motion of vertical direction, the sliding distance around sighting rod 3 is the settlement depth of pile foundation promptly, and then has improved the precision that detects.

The application principle of the high-precision pile foundation settlement detection ruler is as follows: with the vertical one side of placing the pile foundation of main scale 1, rotate the distance between the adjustable backup pad 61 of supporting screw 6 and the bottom plate 5 for main scale 1 can be in vertical state, not hard up locking screw 4 makes dull polish piece 41 and the 12 phase separations of fixed dull polish strip, and slide 2 slides down, pastes mutually up to the last edge of slide 2 and pile foundation, screws up locking screw 4 and carries out the record to the directional scale of pointer 21. And after the pile foundation is settled, loosening the locking screw rod 4 again, sliding the sliding seat 2 downwards until the sliding seat 2 is attached to the upper edge of the pile foundation, and subtracting the readings recorded in the two times to obtain the settlement depth of the pile foundation.

The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
