Description

Technical Field

[0001] This utility model relates to the field of water seepage detection technology, specifically a water seepage detection device for roads and bridges. Background Technology

[0002] In the process of construction quality acceptance, regular health monitoring and maintenance of road and bridge projects, seepage detection is a key step in assessing the waterproof performance and durability of the structure.

[0003] Currently, the industry commonly uses a method of manually setting up temporary sealing rings to construct a closed water storage area for testing. The specific operation involves operators carrying sealing tape, scrapers, and other tools to manually lay sealing strips around the area to be tested, forming a ring-shaped closed boundary. Water is then injected into the area, and the seepage performance is determined by observing water level changes or measuring the amount of seepage. However, this method has several drawbacks. For example, it requires carrying multiple tools on-site, making preparation cumbersome (including cutting and pasting the sealing strips, which is time-consuming and difficult to implement quickly), resulting in low efficiency. Secondly, the sealing quality is highly dependent on the operator's skill; uneven or discontinuous adhesion of the sealing strips can lead to distorted test data. Furthermore, manual operation is poorly adaptable to complex substrates (manually laid sealing rings are difficult to fit tightly), making it difficult to accurately control the amount used, often resulting in wasted sealing strips. Therefore, a road and bridge seepage detection device is proposed to solve these problems. Utility Model Content

[0004] This invention provides a road and bridge seepage detection device, which solves the problem that existing methods are difficult to standardize, thus limiting the improvement of detection efficiency and accuracy.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A road and bridge seepage detection device includes a bottom component, the bottom component includes a base, a water storage cavity is provided at the bottom of the base, an inner isolation support component that can extend or retract from itself is provided in the water storage cavity, a glue storage cavity is also provided on the base outside the water storage cavity, the glue storage cavity is annular, a plurality of glue outlet grooves are arranged in annular array at the bottom, a pressure-sealing capsule is built into the glue storage cavity, the pressure-sealing capsule is provided with sealant, and a squeezing component is provided at the top of the glue storage cavity for squeezing the sealant in the pressure-sealing capsule through the glue outlet grooves to the space between the base and the ground.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the pressure-sealed capsule is annular and includes a flexible package with an easy-open seal at the bottom and an easy-open notch at the center of the seal. The sealant is embedded in the flexible package and the easy-open seal.

[0008] Furthermore, the internal isolation support assembly includes an isolation support ring that can be raised and lowered and is disposed in the water storage chamber, and the base is provided with a lifting mechanism for controlling the raising and lowering of the isolation support ring.

[0009] Furthermore, the lifting mechanism is a telescopic cylinder, and there are multiple lifting mechanisms. The lifting mechanism is located on the top of the seat, and the telescopic end moves through the seat and is fixedly connected to the isolation support ring.

[0010] Furthermore, the top annular array of the isolation support ring has a first limiting rod that moves through the base body, and the top of the first limiting rod is provided with a first limiting head.

[0011] Furthermore, the extrusion assembly includes a top plate disposed at the top of the glue storage cavity, an annular extrusion ring movably disposed below the top plate and located above the pressure-sealing capsule, and an extrusion mechanism disposed on the top plate for controlling the annular extrusion ring to extrude the pressure-sealing capsule.

[0012] Furthermore, the extrusion assembly is a telescopic cylinder, which is multiple in number and arranged in a ring array. It is located at the top of the top plate, and the telescopic end moves through the top plate and is fixed with a ring extrusion ring.

[0013] Furthermore, the glue storage cavity, the pressure-sealing capsule, and the annular extrusion ring are all adapted conical shapes; The top plate is detachably mounted on the top of the glue storage cavity by multiple screws; The top of the annular extrusion ring has a second limiting rod in annular array. The top of the second limiting rod moves through the top plate and is provided with a second limiting head.

[0014] Furthermore, the bottom component also includes a scraper assembly, which includes an annular groove disposed on the outside of the base, a rotating ring rotatably disposed in the annular groove, and scrapers arranged in annular array outside the rotating ring.

[0015] Furthermore, a connecting hole connected to the water storage chamber is provided at the center of the top of the seat; The detection device also includes a metering component, which includes multiple uprights set on the top of the base, a support platform set on the top of the uprights, a metering bucket installed on the support platform, a water supply pipe connected to the bottom outlet of the metering bucket through the support platform and the connecting hole and connected to the water storage chamber, and two symmetrical handles set on the support platform. The seat is also equipped with an exhaust pipe that connects to the water storage chamber.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. This road and bridge seepage detection device integrates a water storage chamber and an internal isolation support component at the bottom of the base, enabling rapid positioning and stable isolation of the detection area. It eliminates the need for temporary manual isolation, greatly simplifying on-site preparation and improving detection efficiency. At the same time, the internal isolation support component provides effective support and extrusion molding conditions for the subsequent application of sealant.

[0017] 2. This road and bridge seepage detection device, through its structural design of an annular glue storage chamber combined with a pressure-sealing capsule and a top extrusion assembly, can automatically release sealant simultaneously through multiple glue outlets to the contact surface between the seat and the ground before the detection process. This, combined with the downward pressure, forms a continuous and sealed boundary. This method not only significantly reduces the reliance on operator skills but also avoids problems such as uneven and intermittent application of glue strips in traditional manual methods, effectively preventing detection errors caused by seal failure. In addition, the sealant is released quantitatively as needed, reducing material waste and on-site environmental pollution. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figure 1-9 As shown, a road and bridge seepage detection device in this embodiment includes a bottom component 1, a metering component 3, and a pressure-sealing capsule 2. The bottom component 1 includes a base 10, an inner isolation support assembly 11, a squeezing assembly 12, and a scraping adhesive assembly 13.

[0022] The bottom of the seat 10 is provided with a water storage chamber 102. The bottom of the water storage chamber 102 is open to facilitate direct contact between water and the road surface. The top center of the seat 10 is provided with a connecting hole 101 that communicates with the water storage chamber 102. The connecting hole 101 is used to connect the metering component 3. The seat 10 is also provided with a glue storage chamber 103 located outside the water storage chamber 102. The glue storage chamber 103 is annular, and its bottom is arranged with multiple glue outlet grooves 104 in an annular array. The seat 10 is also provided with an exhaust pipe 105 that communicates with the water storage chamber 102 to exhaust the air inside the water storage chamber 102.

[0023] The pressure-sealed capsule 2 is annular and built into the glue storage cavity 103. Specifically, it includes a flexible package 201. The bottom of the flexible package 201 is provided with an easy-open seal 202, which can be aluminum foil or aluminum-plastic composite film. An easy-opening notch 203 is provided in the center of the easy-open seal. The flexible package 201 and the easy-open seal 202 are wrapped with sealant 204, which can be butyl sealant or one-component silicone sealant.

[0024] It should be noted that the gap between the dispensing grooves 104 needs to be as small as possible so that the extruded sealant 204 can form a complete sealing structure after being squeezed by the seat body 10.

[0025] With this design, the pressure-sealing capsule 2 can be placed in the glue storage chamber 103 beforehand, and then the pressure of the extrusion assembly 12 can be used to make it crack from the easy-opening notch 203, so that the sealant 204 inside can flow to the ground through the glue outlet 104.

[0026] The inner isolation support assembly 11 includes an isolation support ring 110 that is liftable and disposed in the water storage chamber 102. The outer wall of the isolation support ring 110 is movably fitted with the inner wall of the water storage chamber 102. The seat 10 is provided with a lifting mechanism 113 for controlling the lifting and lowering of the isolation support ring 110. In this embodiment, there are two lifting mechanisms 113, which are symmetrically distributed. The lifting mechanism 113 is specifically an electric telescopic cylinder, a pneumatic telescopic cylinder, or a hydraulic telescopic cylinder. It is specifically disposed on the top of the seat 10, and the telescopic end moves through the seat 10 and is fixedly connected to the isolation support ring 110. Thus, the lifting mechanism 113 can control the extension or retraction of the isolation support ring 110 from the water storage chamber 102.

[0027] When the isolation support ring 110 extends out of the water storage chamber 102, it can lift the seat 10 and other structures on it by contacting the ground with its bottom, and isolate the water storage chamber 102 inside it from the outside. When it retracts into the water storage chamber 102, the seat 10 and other structures on it can be lowered to the ground.

[0028] This design creates the conditions for the application of sealant 204.

[0029] In the preferred embodiment, in order to ensure the stability of the lifting and lowering of the isolation support ring 110, a first limiting rod 111 is provided in the top annular array that can move through the seat body 10. The top of the first limiting rod 111 is provided with a first limiting head 112, and the diameter of the first limiting head 112 is larger than the telescopic hole on the seat body 10.

[0030] In this embodiment, there are four first limiting rods 111, which are arranged in a circular array.

[0031] The extrusion assembly 12 includes a top plate 120 disposed on the top of the glue storage cavity 103. The top plate 120 closes the top of the glue storage cavity 103. An extrusion mechanism 122 is disposed on the top plate 120. In this embodiment, there are four extrusion mechanisms 122 arranged in a circular array. The extrusion mechanism 122 can be an electric telescopic cylinder, a pneumatic telescopic cylinder, or a hydraulic telescopic cylinder. It is specifically disposed on the top of the top plate 120, and the telescopic end moves through the top plate 120 and is fixed with an annular extrusion ring 121.

[0032] With this design, the annular extrusion ring 121 can be controlled to move up and down in the glue storage cavity 103 by the extrusion mechanism 122, thereby achieving the effect of extruding and pressing the sealing capsule 2, so that the sealant 204 in the sealing capsule 2 is discharged from the glue outlet 104 to the ground outside the isolation support ring 110.

[0033] It should be noted that the lifting mechanism 113 and the pressing mechanism 122 are commercially available products and are equipped with existing synchronous telescopic systems.

[0034] To further refine the extrusion location of the sealant 204, the sealant reservoir 103, the pressure-sealing capsule 2, and the annular extrusion ring 121 are all fitted with a cone shape.

[0035] In addition, to facilitate the placement of the pressure-sealing capsule 2, the top plate 120 is detachably mounted on the top of the glue storage cavity 103 by a plurality of screws 125, so that it can be removed from the top plate 120 when needed.

[0036] The top of the glue storage cavity 103 is provided with an installation step that is adapted to the top plate 120. After the top plate 120 is embedded in the installation step, the screw 125 is installed from the outside of the base 10.

[0037] In a preferred embodiment, the top of the annular extrusion ring 121 has a second limiting rod 123 in annular array. The top of the second limiting rod 123 movably passes through the top plate 120 and is provided with a second limiting head 124. The direct diameter of the second limiting head 124 is larger than the telescopic hole on the top plate 120, thereby further improving the stability of the lifting and lowering of the annular extrusion ring 121.

[0038] The adhesive scraping assembly 13 includes an annular groove 130 disposed outside the base 10, a rotating ring 131 rotatably disposed in the annular groove 130, and scrapers 132 arranged in annular array outside the rotating ring 131. In this embodiment, the number of scrapers 132 is specifically six.

[0039] This design allows the scraper 132 to rotate by rotating the rotating ring 131 in the annular groove 130, thereby scraping the sealant 204 that has been squeezed out to the outside of the seat 10 and ensuring the uniformity of the seal at each position.

[0040] Furthermore, a notch 133 is provided on the bottom of the scraper 132 near the seat 10. The notch 133 is triangular, so that when scraping the glue, the glue can be formed to wrap around the seat 10, thereby improving the sealing performance.

[0041] The structure and principle of the metering component 3 are the same as those of the prior art in this field. It includes three uprights 301 set on the top of the base 10, a support platform 302 set on the top of the three uprights 301, a metering tank 303 installed on the support platform 302, and a water supply pipe 304 connected to the bottom water outlet of the metering tank 303, which passes through the support platform 302 and the connecting hole 101 and is connected to the water storage chamber 102. A switch valve is provided on the water supply pipe 304.

[0042] To facilitate operation by construction personnel, two symmetrical handles 305 are also provided on the support platform 302, making it easy to carry the pressing device.

[0043] It should be noted that if the weight of the device itself is insufficient for the testing requirements, a counterweight can be placed on the support platform 302.

[0044] In this embodiment, the isolation support ring 110 extends from the water storage chamber 102, and the device is placed on the ground to be tested. At this time, the bottom of the isolation support ring 110 contacts the ground, supporting the base 10 and its structure, and isolating the water storage chamber 102 from the outside. Then, the compression assembly 12 compresses the pressure-through sealing capsule 2 inside the glue storage chamber 103, causing the sealant 204 inside the pressure-through sealing capsule 2 to flow from the glue outlet 104 to the ground. After the compression is completed, the isolation support ring 110 is retracted, and during this process, the entire device is pressed down, causing the bottom of the base 10 to compress the sealant 204 on the ground, thereby forming a sealing layer. After the compression is completed, the sealant 204 will overflow to the outside of the base 10. By rotating the glue scraping assembly 13, it can be spread evenly. Finally, after the sealant 204 solidifies, the test begins.

[0045] The specific detection method is the same as the existing technology, so it will not be described in detail here.

[0046] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
