[0016] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.
[0017] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0018] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0019] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0020] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0021] like Figure 1 The device shown is for preventing mud spillage during rotary drilling, comprising: a mud tank 1, a retaining ring 2, and geotextile 3. The mud tank 1 is a discarded spoil box, and lifting rings 4 are installed on its side wall for hoisting to other locations as needed. To prevent mud spillage from contaminating the surrounding ground, the mud tank 1 must be higher than the top elevation of the casing 5.
[0022] A circular opening, slightly larger than the outer diameter of the cast-in-place pile casing 5 (5cm), is made at the bottom of the mud box 1. Eighteen L-shaped steel bars, each 10cm high, are welded at a 30° angle along the cut edge. The horizontal bars of the L-shaped steel bars connect to the circular opening, and the vertical bars form a ring. A ring of steel bars is welded to the outer edge of the ring, away from the horizontal bars, to form an integral protective ring 2. Figure 2 As shown. In use, the device is fitted onto the casing 5 of the cast-in-place pile. Geotextile 3 is used to fill the gap between the reinforcing steel ring 2 and the casing 5, ensuring a tight fit between the geotextile 3 and the casing 5 and preventing mud leakage. Simultaneously, the integrated structure formed by the reinforcing steel ring 2 enhances the stability and strength of the device, enabling it to better withstand external forces such as mud pressure.
[0023] During rotary drilling, the prepared mud box 1 is lifted directly above the steel casing 5 and slowly lowered onto the casing 5. The gap between the mud box 1 and the casing 5 is filled by using geotextile 3. The geotextile 3 is wrapped around each L-shaped steel bar in a wave shape, so that the steel bar guard ring 2 fixes the geotextile 3, effectively preventing the geotextile 3 from shifting.
[0024] Finally, it should be noted that the terms "first" and "second", and the like, are used merely to distinguish one element from another, and do not require or imply that these elements must necessarily be in any physical or logical relationship. Also, the terms "comprising", "including", or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus.
[0025] The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units, i.e. may be located in one place or distributed on multiple network units. Some or all of the units can be selected according to actual needs to achieve the purpose of the embodiment.
[0026] In addition, the functional units in each embodiment of the present application can be integrated into one processing unit, or each unit can exist physically, or two or more units can be integrated into one unit. The integrated unit can be realized in the form of hardware or in the form of a software functional unit.
[0027] The integrated unit, if realized in the form of a software functional unit and sold or used as an independent product, can be stored in a computer readable storage medium. Based on this understanding, the technical solutions of the present application, essentially or the part that contributes to the prior art, or the whole or part of the technical solutions can be embodied in the form of a software product. The computer software product is stored in a storage medium, and includes a number of instructions for causing a computer device (which can be a personal computer, a server, or a network device, etc.) to execute all or part of the steps of the methods described in each embodiment of the present application.
