Description

Technical Field

[0001] This utility model belongs to the field of concrete impermeability testing technology, and in particular relates to a concrete impermeability testing device. Background Technology

[0002] Concrete, as a widely used building material, has a permeability resistance that refers to its ability to resist the penetration of water or other liquids (light oil, heavy oil) under pressure. This is a crucial indicator for evaluating the quality and durability of concrete. Therefore, effectively testing the permeability resistance of concrete is key to ensuring that it does not experience problems such as water seepage or peeling during long-term use.

[0003] Currently, the pressure method is one of the commonly used experimental methods for testing the permeability of concrete. It mainly involves applying a certain water pressure test pressure and measuring the flow rate of water passing through the concrete sample under that pressure for a certain period of time, thereby calculating the permeability coefficient of the concrete material. The specific operation process includes: preparing a concrete sample, placing it in a closed container, and then creating a high water pressure on one side of the container using means such as a water pump or air pressure. When the concrete is placed under this pressure difference, water can permeate from the high-pressure side to the low-pressure side within a specified time. By observing and recording the permeation rate, the permeability resistance of the concrete can be evaluated.

[0004] However, under prolonged water pressure, concrete test blocks are prone to loosening and moving upwards, leading to poor sealing performance and affecting the accuracy of impermeability testing. Existing concrete impermeability testing instruments typically use test sleeves fixed with multiple bolts, making installation and disassembly extremely inconvenient and wasting testing time. Furthermore, existing test sleeves are mostly sleeve-type, which is not conducive to demolding. Utility Model Content

[0005] In view of this, the present invention aims to propose a concrete permeability testing device to solve the problems of the existing concrete permeability testing devices being troublesome and laborious to install and disassemble, inconvenient to demold, and the concrete test blocks being prone to loosening and moving upward under long-term water pressure, thus affecting the testing results.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A concrete impermeability testing device includes a testing platform, a base plate, an installation component, and a pressure application component. The base plate is disposed on top of the testing platform, and both the installation component and the pressure application component are disposed on top of the base plate, with the pressure application component positioned above the installation component.

[0008] The mounting components are provided in several groups, and the several groups of mounting components are evenly arranged on the top of the base plate;

[0009] The mounting assembly includes a mounting base and a sleeve assembly. The mounting base is fixedly mounted on the base plate, and the bottom of the sleeve assembly is threadedly connected to the mounting base. The sleeve assembly is used to hold concrete test blocks. The threaded connection between the sleeve assembly and the mounting base not only increases the sealing performance but also facilitates installation and disassembly, saving time and effort.

[0010] Furthermore, the bottom of the mounting base is fixedly connected to the top of the base plate, the mounting base has an internal thread, and the top of the mounting base has an annular groove.

[0011] Furthermore, the sleeve assembly includes a first sleeve and a second sleeve, which are symmetrically arranged. The first sleeve and the second sleeve form a cylindrical tube, and the outer diameter of the cylindrical tube corresponds to the inner diameter of the mounting base.

[0012] The lower side wall of the first sleeve is provided with a first semi-circular platform, and the lower side wall of the second sleeve is provided with a second semi-circular platform corresponding to the first semi-circular platform. The outer diameters of the first and second semi-circular platforms correspond to the outer diameter of the mounting base.

[0013] The bottoms of both the first and second semicircular truncated cones are equipped with sealing rings corresponding to the annular grooves, which are positioned within the grooves. The first and second semicircular truncated cones are located on top of the mounting base, and the sealing rings are inserted into the annular grooves, serving not only as a limiting function but also further enhancing the sealing effect.

[0014] Furthermore, the lower outer walls of the first sleeve and the second sleeve are provided with external threads corresponding to the internal threads, and the external threads are located below the first semicircular platform and the second semicircular platform.

[0015] Furthermore, both ends connecting the first sleeve and the second sleeve are provided with insertion slots, and both ends connecting the second sleeve and the first sleeve are provided with insertion blocks corresponding to the insertion slots. The sleeve assembly adopts the method of assembling the first sleeve and the second sleeve, which facilitates the demolding of the concrete test block. The insertion blocks are inserted into the insertion slots, which not only serve as a limiting function, but also further achieve a sealing effect.

[0016] Furthermore, a first sleeve mounting block is provided on the outer side of both ends where the first sleeve and the second sleeve are connected, and a second sleeve mounting block corresponding to the first sleeve mounting block is provided on the outer side of both ends where the second sleeve and the first sleeve are connected, and the first sleeve mounting block and the second sleeve mounting block are connected by a first bolt.

[0017] The outer sides of both ends where the first and second semicircular truncated cones connect are provided with first semicircular truncated cone mounting blocks, and the outer sides of both ends where the second semicircular truncated cones connect to the first semicircular truncated cones are provided with second semicircular truncated cone mounting blocks corresponding to the first semicircular truncated cone mounting blocks. The first and second semicircular truncated cone mounting blocks are connected by a second bolt.

[0018] The upper parts of the first sleeve and the second sleeve are connected and fixed by the first sleeve mounting block and the second sleeve mounting block, and the lower parts of the first sleeve and the second sleeve are connected and fixed by the first semi-circular truncated block and the second semi-circular truncated block. This not only improves the sealing performance, but also facilitates the demolding of the concrete test block.

[0019] Furthermore, both the first and second sleeves are provided with handles on the upper outer walls. The handles facilitate the screwing of the first and second sleeves into or out of the mounting base, and also make it easier to pick up the concrete test blocks.

[0020] Furthermore, the pressure application assembly includes a first support plate, a second support plate, a top plate, a pressure plate, and a cylinder. The first and second support plates are disposed at both ends of the base plate. One end of the top plate is disposed on the top of the first support plate, and the other end of the top plate is disposed on the top of the second support plate. The mounting end of the cylinder is connected to the bottom center of the top plate, and the output end of the cylinder is connected to the top center of the pressure plate. Both ends of the pressure plate are slidably disposed on the inner walls of the first and second support plates.

[0021] Furthermore, the pressure plate is provided with sliders at both ends, and the inner walls of the first support plate and the second support plate are provided with grooves corresponding to the sliders.

[0022] The pressure plate is lowered by a cylinder, which makes the pressure plate fit tightly with the sleeve assembly and concrete test block below. This not only improves the sealing of the equipment, but also helps to prevent the concrete test block from loosening and moving upward under the water pressure below, thus improving the accuracy of the test results.

[0023] The pressure plate has several through-hole observation holes, the positions of which correspond to the positions of the sleeve assemblies, and the number of observation holes corresponds to the number of sleeve assemblies. The inner diameter of the observation holes is smaller than the inner diameter of the cylindrical tube formed by the first and second sleeves. The inside of the observation holes will press the concrete test block inside the sleeve assembly firmly to prevent the concrete test block from loosening and moving upward under the water pressure below, while not affecting the observation of water seepage.

[0024] Furthermore, the base plate is provided with a number of water injection holes, which are connected to the interior of the testing platform. The number of water injection holes corresponds to the number of mounting components, and the position of the water injection holes corresponds to the position of the center of the mounting base.

Water in the testing platform 1 is pressurized to the concrete test block through the water injection hole. The water seepage is observed through the observation hole 27 and the testing platform 1 is used to detect the water seepage.
