Detailed Description
The application is described in further detail below with reference to fig. 1-7.
The embodiment of the application discloses an assembled building foundation settlement monitoring device.
Referring to fig. 1, an assembled building foundation settlement monitoring device comprises a monitoring water tank 3 and a reference water tank 4. At least one reference water tank 4 is arranged, and the number of the monitoring water tanks 3 is the same as the number of the planned monitoring points after the construction of the assembled building is completed. Monitoring points are typically located at the beam column and corner of the fabricated building.
Referring to fig. 1 and 2, a telescopic rod 1 is fixedly installed at the bottom side of a reference water tank 4, and a support plate 2 is fixedly installed at the bottom end of the telescopic rod 1. The bottom surface of the support plate 2 is fixedly provided with an anchor rod 5, and the anchor rod 5 is used for being inserted into the ground outside the building. The reference water tank 4 is inserted into the ground outside the building through the anchor rod 5, so that the situation that the building subsides to drive the reference water tank 4 to subside is reduced. After the anchor rod 5 is inserted into the ground, the support plate 2 can be abutted against the ground, so that the condition that the reference water tank 4 automatically descends under the weight of the reference water tank is reduced.
Referring to fig. 1 and 3, the monitoring water tank 3 is provided with a mounting seat 6. The monitoring water tank 3 is connected with the outer side wall of the building through the mounting seat 6, so that the stability of the connection of the monitoring water tank 3 to the outer wall of the building is improved, and the condition that the monitoring water tank 3 shakes under the blowing of wind is reduced.
Referring to fig. 1, a hose 7 is connected between the bottom side of the monitoring water tank 3 and the bottom side of the reference water tank 4. The hose 7 is routed from the inside of the telescopic rod 1, and then is extended from the peripheral side wall of the support plate 2 to be connected to the monitoring water tank 3. In the embodiment of the application, only one reference water tank 4 is connected to the bottom side of each monitoring water tank 3 after being divided into a plurality of heads by one end of a hose 7. If there are two or more reference water tanks 4, the reference water tanks 4 are connected to several monitoring water tanks 3 through hoses 7, respectively.
Referring to fig. 4, 5 and 6, the top side of the monitoring water tank 3 and the top side of the reference water tank 4 are provided with ventilation holes 8. The reference water tank 4 and the monitoring water tank 3 are communicated through a hose 7, and the air pressure is balanced by an air vent 8. According to the principle of the communicating vessel, the water level of the reference water tank 4 is equal to the water level of the monitoring water tank 3.
Referring to fig. 4 and 5, a float rod 9 is provided inside each of the monitoring water tank 3 and the reference water tank 4. After the building is settled, the building is settled by the monitoring water tank 3, and then water in the reference water tank 4 flows to the monitoring water tank 3 from the hose 7, so that the water level of the reference water tank 4 is equal to the water level of the monitoring water tank 3. But the floating rods 9 are immersed in the length portions of the inside of the reference water tank 4 and the monitoring water tank 3 so that the floating rods 9 in the inside of the reference water tank 4 and the monitoring water tank 3 are subjected to different buoyancy forces. The buoyancy difference suffered by the floating rods 9 in the monitoring water tank 3 and the reference water tank 4 is detected, so that the settlement of the building is conveniently calculated.
Referring to fig. 4, 5 and 7, the computer 10 is further included, and the computer 10 is placed inside the building. The top side of the monitoring water tank 3 and the top side of the reference water tank 4 are embedded with pressure sensors 11. Temperature sensors 12 are mounted on the inner side wall of the monitoring water tank 3 and the inner side wall of the reference water tank 4. Each of the pressure sensor 11 and the temperature sensor 12 is electrically connected to the computer 10.
After water is injected into the monitoring water tank 3 and the reference water tank 4, the floating rod 9 is driven by the buoyancy of the water to squeeze the pressure sensor 11. The pressure sensor 11 detects the buoyancy of the water in the reference water tank 4 on the float rod 9, and generates a reference signal, and the pressure sensor 11 transmits the reference signal to the computer 10. The pressure sensor 11 detects and monitors the buoyancy of the water in the water tank 3 to the floating rod 9, and then generates a pressure signal, and the pressure sensor 11 sends the pressure signal to the computer 10. The temperature sensor 12 then detects the water generation temperature signal inside the reference water tank 4 and the monitoring water tank 3, and the temperature sensor 12 sends the temperature signal to the computer 10.
A relation table between the temperature and the density of the introduced water is preset in the computer 10, and then a reference temperature is set. The computer 10 converts the reference signal into a signal corresponding to the reference temperature according to the relation table, the reference temperature, and the temperature signal, and converts the pressure signal into a signal corresponding to the reference temperature.
The computer 10 then calculates the difference between the reference signal and the pressure signal and determines the magnitude of settlement of the fabricated building from the difference. A differential pressure threshold is preset in the computer 10, the differential pressure threshold being the maximum difference between the reference signal and the pressure signal. When the difference between the reference signal and the pressure signal is larger than the pressure difference threshold value, the sedimentation amplitude of the assembled building is large, and workers timely contact staff to repair the assembled building, so that the situation that the assembled building collapses due to large sedimentation amplitude after being built is reduced.
The computer 10 also compares the difference value between each pressure signal, and the larger the difference value between each pressure is, the larger the inclination amplitude of the fabricated building is, so that staff can timely contact staff to repair the fabricated building, and the condition that the fabricated building is large in inclination amplitude and collapses after being built is reduced.
Referring to fig. 2 and 3, a first shielding plate 13 is provided on the top side of the monitoring water tank 3, and a first connecting rod 16 is fixedly connected between the first shielding plate 13 and the top side of the monitoring water tank 3. The top side of the reference water tank 4 is provided with a second shielding plate 14, and a second connecting rod 17 is fixedly connected between the second shielding plate 14 and the top side of the monitoring water tank 3. The first shielding plate 13 and the second shielding plate 14 play a role of sunshade, thereby reducing the occurrence of damage of the monitoring water tank 3 and the reference water tank 4 under sunlight exposure.
Referring to fig. 2 and 4, an overflow port 18 is formed in the side wall of the reference water tank 4. When water is added to the inside of the reference water tank 4, if the water level in the inside of the reference water tank 4 is higher than the overflow port 18, water is discharged from the overflow port 18, thereby limiting the water level of the reference water tank 4. By limiting the water level in the reference water tank 4, a space is reserved between the water surface of the monitoring water tank 3 and the inner top wall of the monitoring water tank 3, and the monitoring water tank 3 is convenient to rise along with the descending of the assembled building.
Referring to fig. 4 and 6, the second shielding plate 14 is provided with water outlet holes 19, and the water outlet holes 19 are aligned with each other right above the ventilation holes 8. The second shielding plate 14 is gradually lifted to the periphery gradually and is obliquely arranged at the position of the water outlet hole 19. A water inlet funnel 20 is arranged below the second shielding plate 14, and the neck of the water inlet funnel 20 is fixedly inserted into the vent hole 8.
The water in the reference water tank 4 is partially evaporated and discharged from the vent hole 8, and the water in the reference water tank 4 flows to the monitoring water tank 3, so that the water in the reference water tank 4 is continuously reduced. When water needs to be added into the reference water tank 4, the water is directly poured into the second shielding plate 14, and flows from the water outlet hole 19 to the water inlet funnel 20 under the inclined guide of the shielding plate. After that, water flows from the water inlet funnel 20 to the inside of the reference water tank 4, thereby facilitating the water replenishment to the inside of the reference water tank 4.
In rainy days, rainwater falls into the second shielding plate 14, the rainwater on the second shielding plate 14 is discharged into the water inlet funnel 20 from the water outlet hole 19, and then the rainwater is discharged into the reference water tank 4 from the water inlet funnel 20. Also, the diurnal temperature difference is generated to cause the vapor to condense and then be discharged from the second shielding plate 14 into the reference water tank 4. The water in the reference water tank 4 is replenished by rainwater and water vapor in the air, thereby reducing the frequency of adding water to the reference water tank 4.
Referring to fig. 4, the reference water tanks 4 are each provided with a filter cartridge 21, and the filter cartridges 21 are each hollow around the float rod 9. A space is left between the outer wall of the filter cartridge 21 and the inner wall of the reference water tank 4, and the vent hole 8 is located outside the projection area of the filter cartridge 21 in the height direction. The inner top wall and the inner bottom wall of the reference water tank 4 are respectively provided with a ring groove 22 for the end part of the filter cartridge 21 to penetrate.
Water enters between the outer wall of the filter cartridge 21 and the inner wall of the reference water tank 4 through the vent hole 8, and then flows into the filter cartridge 21 after being filtered, so that dust is reduced from being stuck to the floating rod 9. When dust adheres to the float rod 9, the weight of the float rod 9 increases, thereby reducing the pressure of the float rod 9 against the pressure sensor 11. By reducing the occurrence of dust sticking to the float rod 9, the accuracy of the pressure sensor 11 in detecting the pressure of the water applied to the float rod 9 is improved.
Referring to fig. 4, a plurality of first stopper rods 23 are fixedly installed on the inner wall of the filter cartridge 21, the first stopper rods 23 abut against the rod bodies of the floating rods 9 located inside the filter cartridge 21, and the first stopper rods 23 are disposed around the floating rods 9 located inside the filter cartridge 21. The inner wall fixed mounting of monitoring water pitcher 3 has many second gag lever posts 24, and second gag lever post 24 supports the pole body of the inside floating rod 9 of being located monitoring water pitcher 3, and second gag lever post 24 encircles the inside floating rod 9 setting of being located monitoring water pitcher 3.
The first limiting rod 23 is used for limiting the movement of the floating rod 9 in the reference water tank 4, and the second limiting rod 24 is used for limiting the movement of the floating rod 9 in the monitoring water tank 3, so that the floating rod 9 and the pressure sensor 11 are arranged opposite to each other conveniently, and the accuracy of the pressure sensor 11 in detecting the buoyancy force suffered by the floating rod 9 is improved.
Referring to fig. 4, pontoons 15 are provided inside the reference water tanks 4, and the pontoons 15 are empty to be sleeved on the filter cartridges 21. A plurality of third limiting rods 25 are fixedly arranged on the peripheral side wall of the pontoon 15, and a space is reserved between the pontoon 15 and the inner wall of the reference water tank 4 through the third limiting rods 25. A magnetic ring 26 is arranged on the bottom side of the pontoon 15, and a first magnetic block 27 is arranged below the pontoon 15. The inside wall of the reference water tank 4 is provided with a chute 29 for lifting and sliding the first magnetic block 27, and a part of the first magnetic block 27 extends out of the chute 29. The second magnetic block 28 is fixedly arranged on the inner top wall of the sliding groove 29. The first magnet 27 is used for attracting the magnet ring 26 and the second magnet 28.
When the water level of the reference water tank 4 drops, the distance between the first magnet 27 and the magnetic ring 26 decreases, and the attractive force between the first magnet 27 and the magnetic ring 26 increases. By increasing the attractive force between the first magnet 27 and the magnet ring 26, the portion of the pontoon 15 immersed in the water in the reference water tank 4 is increased. The submerged portion of the pontoon 15 increases, thereby delaying the descent speed of the water in the reference water tank 4.
Referring to fig. 4, after the first magnet 27 and the magnetic ring 26 are abutted against each other, if the sum of the magnetic force between the first magnet 27 and the second magnet 28 and the buoyancy of the water to the first magnet 27 and the pontoon 15 is greater than the weight of the first magnet 27 and the pontoon 15, the first magnet 27 and the second magnet 28 are separated, and the pontoon 15 is sunk into the bottom side of the reference water tank 4, thereby delaying the water lowering speed in the reference water tank 4.
