Description

Technical Field

[0001] The invention relates to the field of concrete testing equipment, in particular to a quality testing tool for concrete cracks after treatment. Background Art

[0002] With the continuous advancement of construction technology in the construction field, the quality requirements of concrete are also increasing. In the process of concrete construction, cracks are inevitable. During the service of concrete materials, structural and non-structural cracks will occur due to various internal and external factors such as plastic shrinkage, dry shrinkage, structural deformation, external loads, etc. After the above cracks are generated and expanded to a certain extent, if they are not repaired in time, they will endanger the safety, durability and normal use of the structure. If they are allowed to expand and penetrate, they may even cause catastrophic accidents. For concrete structure cracks with waterproofing requirements in water conservancy projects, chemical slurry needs to be poured into the cracks to fill them.

[0003] The actual construction process of repairing cracks with the existing technology is that the technicians estimate the depth of the cracks on the concrete surface based on their experience according to the actual development of the cracks, and drill oblique grouting holes roughly according to the estimated depth, and then use the grouting holes to grout the inside of the cracks. When the slurry seeps out from the crack surface, the grouting is considered completed.

[0004] The Chinese invention patent application document with application announcement number CN108445074A discloses a device and method for inspecting the repair effect of concrete cracks, including a support, a measuring hole, a depth rod and a main controller. The depth rod is inserted into the measuring hole through the through hole of the support. The depth rod is provided with a magnetic probe. The inspection device also includes a depth measuring device. Both the magnetic probe and the depth measuring device are data-connected to the main controller. The key to the method is to configure magnetic grouting material and repair cracks, apply an external magnetic field, fit the relationship diagram between magnetic induction intensity and depth and obtain the inflection point.

[0005] The above-mentioned existing technical solutions have the following defects: during the inspection process, it is necessary to carry out a pressure test on the cracks, inject water into the cracks, and determine the quality of the crack treatment based on the pressure loss of the pressure pump. The traditional pressure pump can only detect the pressure loss value, and cannot accurately measure the water absorption of the concrete cracks when the pressure is stable. Summary of the invention

[0006] The purpose of the present invention is to provide a tool for detecting the quality of concrete cracks after treatment, which has the effect of accurately measuring the quality of crack treatment.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] A tool for inspecting the quality of concrete cracks after treatment, comprising a tank body, the tank body being provided with a main water level gauge, the tank body being provided with a main pressure gauge for detecting the inner cavity pressure of the tank body, the tank body being provided with an exhaust pipe, the exhaust pipe being provided with an exhaust valve, the tank body being provided with a water outlet pipe connected to its inner cavity, the tank body being provided with an air inlet pipe connected to its inner cavity, the air inlet pipe being connected to the air inlet valve.

[0009] By adopting the above technical scheme, the exhaust valve of the exhaust hole is opened, the air inlet valve is opened, and a proper amount of water is poured into the tank body through the air inlet pipe. The amount of water in the tank body is judged by observing the main water level gauge, the exhaust valve is closed, the air inlet pipe is connected to the air pump, and the indication of the main pressure gauge is observed. After the pressure is raised to the specified value, the air inlet valve is closed, and after waiting for a period of time, the value of the pressure value of the main pressure gauge and the water amount indication of the main water level gauge are recorded. The area of ​​the cross-section of the tank body is a fixed value. After calculation, the pressure loss value and the water loss in the tank body can be obtained, thereby obtaining the pressure loss value of the repaired crack and the water absorption of the concrete, and detecting whether the treatment of the concrete crack meets the regulations.

[0010] The present invention is further configured as follows: the tank body is connected to a water replenishing tank, the water replenishing tank is connected to a water replenishing valve, the water replenishing tank is provided with a pressurizing mechanism, the pressurizing mechanism pressurizes the water in the water replenishing tank so that the water pressure is higher than the air pressure in the tank body, and the water replenishing tank is provided with a water replenishing pressure gauge.

[0011] By adopting the above technical solution, when the water in the tank flows out through the water outlet pipe, the water supply valve is opened. After the water supply valve is opened, the water in the water supply tank enters the tank through the water supply pipe, so that the water in the tank reaches the initial height. The water level controller controls the water supply valve to close, thereby maintaining the water volume in the tank stable, reducing the error of the pressure reduction in the tank due to the outflow of water in the tank, and improving the accuracy of the detection result.

[0012] The present invention is further configured as follows: the water supply valve is an electric water valve, a water level sensor is arranged in the tank body, the water level sensor is electrically connected to a water level controller, and the water level controller controls the opening and closing of the water supply valve.

[0013] By adopting the above technical solution, when the water level sensor detects that the water level in the tank body has dropped, the water level sensor sends an electrical signal to the water level controller, and the water level controller controls the opening of the water supply valve, and the water in the water supply tank enters the tank body to keep the water amount in the tank body stable.

[0014] The present invention is further configured as follows: the pressurizing mechanism includes a pressurizing sleeve fixed in the water replenishing tank, a pressurizing piston is slidably connected to the pressurizing sleeve, a sealing ring that contacts and presses the side of the pressurizing sleeve is provided on the side of the pressurizing piston, and a pressurizing rod is connected to the pressurizing piston to drive the pressurizing piston to slide along the inner surface of the pressurizing sleeve.

[0015] By adopting the above technical solution, people observe the indications of the water supply pressure gauge and the main pressure gauge with their eyes, rotate the pressure rod, and the pressure rod drives the pressure piston to move, thereby reducing the actual volume in the water supply tank and increasing the pressure in the water supply tank, thereby maintaining the pressure in the extrusion mechanism greater than the pressure in the tank body.

[0016] The present invention is further configured as follows: the pressure rod is rotatably connected to the pressure piston, and a fixing ring fixed to the pressure sleeve is threadedly connected to the pressure rod.

[0017] By adopting the above technical solution, the pressure rod is rotated, and the pressure rod is restricted by the fixing ring to push the pressure piston to slide along the inner side of the pressure sleeve, so that the pressure rod pushes the pressure piston and keeps the pressure piston stable.

[0018] The present invention is further configured as follows: the water supply tank is provided with a pressure transmission pipe connected to the tank body, the pressure transmission pipe is provided with a one-way valve, and the one-way valve can allow the air in the tank body to enter the water supply tank.

[0019] By adopting the above technical scheme, through the setting of the pressure transmission pipe and the one-way valve, when a pressure pump is used to inject high-pressure air into the tank, the pressure in the tank can enter the water replenishing tank through the pressure transmission pipe to increase the pressure in the water replenishing tank, thereby eliminating the operation of injecting high-pressure air into the tank through the water filling pipe.

[0020] The present invention is further configured as follows: the pressurizing mechanism includes a pressurizing pump, and the pressurizing pump is electrically connected to the water level controller.

[0021] By adopting the above technical solution, when the water level controller controls the water supply valve to open, the pressure pump is turned on at the same time to inject high-pressure air into the water supply tank, thereby keeping the pressure in the water supply tank greater than the pressure in the tank body.

[0022] The present invention is further configured as follows: a support frame is fixedly provided on the tank body, and the support frame is used for hanging and winding the water outlet pipe.

[0023] By adopting the above technical solution, the water outlet pipe needs to be set to a longer length to allow the detection tube to be moved and inserted into the detection gap. The setting of the support frame makes it easy for the water outlet pipe to be wrapped around the tank body, which is convenient for the mobile storage of the detection tool.

[0024] In summary, the beneficial effects of the present invention are:

[0025] 1. Open the exhaust valve of the exhaust hole, open the air inlet valve, pour a proper amount of water into the tank through the air inlet pipe, judge the amount of water in the tank by observing the main water level gauge, close the exhaust valve, connect the air inlet pipe to the air pump, observe the indication of the main pressure gauge, raise the pressure to the specified value, close the air inlet valve, wait for a while, record the pressure value of the main pressure gauge and the water indication of the main water level gauge, the area of ​​the cross section of the tank is a fixed value, and the pressure loss value and water loss in the tank can be calculated, so as to obtain the pressure loss value of the repaired crack and the water absorption of the concrete, and detect whether the treatment of the concrete crack meets the requirements;

[0026] 2. When the water in the tank flows out through the outlet pipe, the water supply valve opens. After the water supply valve opens, the water in the water supply tank enters the tank through the water supply pipe, so that the water in the tank reaches the initial height.
