[0002] In the process of pile foundation drilling construction, wall-protecting mud is often used to balance the water and soil pressure around the hole. The performance of the wall-protecting mud directly affects the stability of the hole wall. The method for testing the performance of the wall-protecting mud is to use a device to sample the mud at different depths, and then test all mud samples for parameters such as specific gravity, viscosity, sand content, and pH value. The accuracy of the mud samples taken directly affects the judgment results of the performance of the wall-protecting mud. During actual on-site construction, wall-protecting mud at different depths is often sampled using a homemade cone bucket and a measuring rope. The mud samples taken by this method have poor reliability, and can only sample mud at one depth at a time, which is time-consuming and labor-intensive. Utility Model Content

DETAILED DESCRIPTION

[0014] The technical solution of the utility model is described in detail below with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.

[0015] Reference Figures 1 to 3The utility model provides a wall protection mud sampling device, which mainly comprises a sampling barrel 4, a compartment system arranged in the sampling barrel 4, a lifting lug 8, a connecting rope 2 connected to the sampling barrel 4 and a measuring rope 1 with a scale;

[0016] The sampling barrel 4 is a cylindrical barrel made of iron sheet. The upper and lower end surfaces of the sampling barrel 4 are sealed by welding of circular iron sheets. A connecting hole with a diameter of 8 mm is opened in the center of the two circular iron sheets. A slurry inlet and a slurry discharge port are respectively opened on the upper and lower surfaces of the cylindrical barrel. The slurry inlet is controlled by a slurry inlet rotary switch 3 for slurry inflow, and the slurry discharge port is controlled by a slurry outlet rotary switch 5 for slurry outflow.

[0017] In the utility model, the slurry inlet rotary switch 3 includes an iron sheet and a first bolt column 302 of the same size as the slurry inlet. The first bolt column 302 is horizontally welded on the surface of the barrel body. The first bolt column 302 is located in the middle position of the slurry inlet. An iron sheet sleeve is sleeved on the first bolt column 302. The iron sheet is welded to the sleeve on the first bolt column 302. A first counterweight block 301 is arranged at the lower end of the iron sheet. The connecting rope 2 can be reliably hung on the first counterweight block 301 (it can be replaced by steel bars). By pulling the connecting rope 2, the lower end of the iron sheet will be lifted up and extend out of the surface of the sampling barrel 4, and the other end will extend into the interior of the sampling barrel 4 to limit the rotation of the compartment plate.

[0018] In the utility model, the slurry outlet rotary switch 5 comprises an iron sheet of the same size as the slurry outlet and a slurry outlet rotary switch 501, the slurry outlet rotary switch 501 is horizontally welded on the barrel surface, the slurry outlet rotary switch 501 is located in the middle position of the slurry outlet, the slurry outlet rotary switch 501 is sleeved with an iron sheet sleeve, the iron sheet is welded to the sleeve on the slurry outlet rotary switch 501, and a second counterweight block 502 is arranged at the lower end of the iron sheet. Compared with the slurry inlet, a vertical bolt column 503 welded on the iron sheet at the lower end edge of the slurry outlet is added, the vertical bolt column 503 is provided with an iron sheet sleeve, and a limit block 504 is welded on the iron sheet sleeve, and the slurry outlet is closed or opened by rotating the limit block 504.

[0019] Furthermore, the compartment system includes a connecting rod 7, a sleeve sleeved on the connecting rod 7, and three compartment plates 6 welded on the sleeve: the connecting rod 7 is made of 8mm steel bars, and is fixed by bolts after passing through two connecting holes; the sleeve is rolled from iron sheet and sleeved on the connecting rod 7, and the three compartment plates 6 are made of steel plates, one side of which is fully welded to the sleeve, and the other three sides are tightly fitted to the inner surface of the sampling barrel 4. The three compartment plates 6 have an angle of 120° with each other and can rotate under the action of external force. When sampling, the slurry inlet switch blocks the rotation of the compartment plates 6; after a single sampling is completed, the slurry inlet switch is closed, and under the action of gravity, the mud sample obtained will drive the compartment plates 6 to rotate, so that the compartment opposite to the slurry inlet is empty.

[0020] Furthermore, the lifting lug 8 is formed by bending two steel wires, one end of each steel wire is connected to the connecting rod 7 at the end face of the sampling barrel 4, and the other end is twisted and fastened together and then bent into a ring; the measuring rope 1 is hung on the ring.

[0021] The specific implementation method of the utility model is: according to the construction needs, the iron sheet is cut and rolled into a cylindrical barrel, and the compartment system is configured according to the actual size of the inner diameter of the sampling barrel 4 to ensure that the compartment plate 6 is tightly fitted with the inner surface of the barrel. After the compartment system is installed, the iron sheet is sealed on both ends of the barrel, and the connecting rod 7 and the lifting lug 8 are tightened one by one. The slurry inlet and the slurry discharge port are installed and processed, and the connecting rope 2 is firmly hung on the first counterweight block 301 of the slurry inlet, and the slurry discharge port limit block 504 is rotated to the blocking position. After the device is assembled, the measuring rope 1 with the scale line is tied to the lifting lug 8, and the sampling barrel 4 is slowly lowered to the required wall protection mud sampling depth, and the connecting rope 2 is pulled and held for about 15 seconds, and the connecting rope 2 is loosened. At this time, one compartment in the sampling barrel 4 has obtained a mud sample of the depth; repeat the operation until three mud samples of different depths are obtained, and then the measuring rope 1 is slowly pulled to lift the sampling barrel 4. After there is no obvious mud flowing out of the surface of the sampling barrel 4, the slurry inlet switch is turned on, and the slurry outlet limit block 504 is opened to allow the mud sample 1 to flow out, and then the limit block 504 is closed, and the slurry inlet switch is closed, so that the compartment 2 in the barrel rotates to the slurry outlet, and the operation is repeated until three mud samples are taken out. Finally, the sampling barrel 4 is rinsed clean and reserved for next use.

[0022] The utility model ensures the accuracy of wall protection mud sampling, and wall protection mud sampling construction at different depths can be carried out in a single lowering, thereby improving construction efficiency. Moreover, the raw materials can be made of on-site waste materials, which is convenient for on-site construction operations, saves time and effort, saves costs, and is green and environmentally friendly.

[0023] As above, although the utility model has been shown and described with reference to a specific preferred embodiment, it should not be interpreted as limiting the utility model itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the utility model defined in the attached claims.
