Description

Technical fields:

[0001] This utility model relates to the field of geological exploration technology, specifically to a slope seepage flow measurement device. Background technology:

[0002] Slopes, as common geological structures in engineering construction, are widely found in road administration, water conservancy and hydropower, geology, mining, and various other engineering fields. Slope stability is crucial for the safe operation of projects and the safety of the surrounding environment. Slope seepage is one of the key factors affecting slope stability. Seepage reduces the effective stress of the soil and rock mass, decreases shear strength, and increases pore water pressure, thereby reducing slope stability. When the seepage flow is large, it may trigger local or overall slope sliding, causing landslides, leading to road interruptions, traffic paralysis, and threatening the safety of pedestrians and vehicles.

[0003] Currently, water pipes and horizontal boreholes are frequently used to drain seepage from slopes and eliminate potential instability risks. However, there is a lack of effective means to measure the seepage flow rate of slopes, making it impossible to accurately grasp the changes in the seepage flow rate and conduct long-term observations of the seepage flow rate, resulting in a lack of data for slope stability analysis. Utility model content:

[0004] The purpose of this invention is to provide a slope seepage flow measurement device.

[0005] This utility model is implemented by the following technical solution: a slope seepage flow measurement device, which includes a bracket, a connector, a water collection tarpaulin, a guide pipe, a flow meter and a three-way valve;

[0006] The bottom of the bracket is provided with a horizontally arranged mounting ring, and the connector is fixed in the mounting ring; the water collection tarpaulin includes an extension and a flattened tarpaulin funnel structure, the tarpaulin funnel structure is integrally formed with the extension, the two side edges of the extension are respectively fitted onto the bracket, and the tarpaulin funnel structure is placed in the top opening of the connector;

[0007] The bottom of the connector is provided with an external thread, and the bottom of the connector is screwed to the guide pipe. The flow meter is provided on the guide pipe, and the three-way valve is installed on the guide pipe between the connector and the flow meter.

[0008] Preferably, the top opening of the connector has an outwardly extending flange, and when the connector is placed inside the mounting ring, the bottom surface of the flange abuts against the mounting ring.

[0009] Preferably, the water collection tarpaulin is made of silicone waterproof canvas.

[0010] Preferably, an adhesive portion is provided at the top outer edge of the water collection tarpaulin, and the adhesive portion is bonded to the slope below the infiltration outlet by an adhesive.

[0012] Advantages of this invention: This invention includes a support frame, a connector, a water collection tarpaulin, a guide pipe, a flow meter, and a three-way valve.

Detailed implementation method:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-5 As shown, a slope seepage flow measurement device includes a support 1, a connector 2, a water collection tarpaulin 3, a guide pipe 4, a flow meter 5, and a three-way valve 6.

[0022] The bottom of the bracket 1 is provided with a horizontally arranged mounting ring 1.1. The bracket 1 is made of aluminum alloy, which is lightweight and easy to carry outdoors. It is also strong and corrosion resistant, and can maintain good support performance in humid, acidic and alkaline environments. A connector 2 is installed inside the mounting ring 1.1. The connector 2 is used to connect the water collection tarpaulin 3 and the guide pipe 4. The top opening of the connector 2 extends outward with a flange 2.1. When the connector 2 is placed inside the mounting ring 1.1, the bottom surface of the flange 2.1 abuts against the mounting ring 1.1. The connector 2 and the bracket 1 are detachably connected for easy and quick replacement on site.

[0023] The water-collecting tarpaulin 3 is made of silicone waterproof canvas with a nano-hydrophobic coating. It is highly tough, with good tear resistance and elongation properties, making it suitable for seepage surfaces on fractured rock masses and various soil slopes. It effectively collects seepage water. The tarpaulin 3 includes an extension 3.1 and a flattened funnel structure 3.2, which is integrally formed with the extension 3.1. An adhesive part 3.3 is located on the top outer edge of the extension 3.1. The adhesive part 3.3 is bonded to the slope surface 7 below the seepage outlet using an adhesive. The adhesive is a sealing putty, suitable for filling tiny gaps in the slope surface 7, compensating for slope surface 7 undulations, effectively sealing the contact area with the slope surface 7, and is environmentally friendly and odorless, causing no secondary pollution to the collected seepage water. The two sides of the extension 3.1 are respectively fitted onto a support 1. The tarpaulin 3 provides support for the water collection tarpaulin. The funnel structure 3.2 of the tarpaulin is placed inside the top opening of the connector 2 to achieve directional water collection. The bottom of the connector 2 is provided with an external thread, and the bottom of the connector 2 is screwed to connect to the guide pipe 4 for easy disassembly and replacement. The guide pipe 4 is made of flexible metal hose, which is easy to bend and adapt to the site environment. A flow meter 5 is installed on the guide pipe 4. The flow meter 5 is a replaceable turbine flow meter or an electromagnetic flow meter. The flow meter 5 measures the seepage flow rate. A three-way valve 6 is installed on the guide pipe 4 between the connector 2 and the flow meter 5. The empty valve port of the three-way valve 6 serves as a sewage outlet. In the early stage of seepage collection, the water sample contains a lot of impurities. Directly using the flow meter 5 for measurement may cause it to become blocked or even damaged. The three-way valve 6 discharges the turbid water mixed with mud and sand and other impurities, which protects the flow meter 5. When the water quality is good, the guide pipe 4 is opened for seepage flow measurement.

[0024] Working process: Use sealing putty to bond the adhesive part 3.3 of the water collection tarpaulin 3 of this device to the slope surface 7 below the seepage outlet of the rock / soil slope. After the adhesion is firm, let it stand for 5 minutes. Bend the guide pipe 4 to the required shape to adapt to the site environment. When the seepage water from the slope enters the guide pipe 4 through the extension part 3.1 and the funnel structure 3.2 of the tarpaulin 3, turn the three-way valve 6 to discharge the initially collected seepage water containing impurities such as mud and sand through the three-way valve 6. Turn the three-way valve 6 again to open the guide pipe 4. The relatively clean seepage water passes through the flow meter 5 along the guide pipe 4. Observe the reading of the flow meter 5.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
