Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction technology, and specifically to a mud circulation structure for underwater pile casing. Background Technology

[0002] Currently, when constructing bored piles across rivers and other bodies of water, the industry typically places a steel mud pit on a steel platform and uses specialized mud extraction equipment to remove the mud generated inside the pile casing during construction. This usually requires renting specialized equipment, which is expensive and increases construction costs, making it uneconomical. Furthermore, installing the specialized equipment takes a significant amount of time, reducing construction efficiency. Placing the steel mud pit on the steel platform also occupies already limited space, reducing worker workspace and impacting construction progress. Utility Model Content

[0003] One of the objectives of this invention is to provide a mud circulation structure for underwater pile casing, in order to solve the problem of high construction costs caused by the need for additional mud pits during the construction of cast-in-place piles in the prior art, thereby reducing the cost of cast-in-place pile construction.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A mud circulation structure for underwater pile casings, used for mud circulation during the construction of two adjacent underwater piles, includes: a first steel casing, a second steel casing, and a flow guiding component. The first and second steel casings are used for the construction of two adjacent underwater piles, respectively. The flow guiding component connects the first and second steel casings and is configured to control the flow direction of the mud between the first and second steel casings. A mud pump and a mud pipe are also included, with both ends of the mud pipe located inside the first and second steel casings, respectively, to connect them. The mud pump is installed at one end of the mud pipe to pump mud from the first steel casing to the second steel casing, or to pump mud from the second steel casing to the first steel casing.

[0006] Based on the above-mentioned technical means, when constructing the first steel casing, the second steel casing is used as a mud pool for mud circulation, and when constructing the second steel casing, the first steel casing is used as a mud pool for mud circulation. There is no need to install an additional mud pool, which reduces construction costs and is economical. The flow direction of the mud between the first and second steel casings is controlled by the flow guiding component, which has strong adaptability. At the same time, this solution has a simple structure, is convenient to construct, and has high construction efficiency.

[0007] Furthermore, it also includes a partition plate, which is installed inside the first steel casing or the second steel casing for rapid sedimentation; the flow guiding assembly and the mud pump are located on both sides of the partition plate.

[0008] According to the above technical means, the flow guiding component and the mud pump are respectively located on both sides of the partition plate. When the flow guiding component guides the mud in the first steel casing to the second steel casing, or guides the mud in the second steel casing to the first steel casing, the partition plate can intercept the slag in the mud and make it settle quickly. This further enables the mud pump on the other side of the partition plate to extract the upper mud, ensuring smooth mud circulation during construction.

[0009] Furthermore, the inner sidewalls of the first steel casing and / or the second steel casing are formed with positioning grooves, and the side of the partition plate is installed in the positioning grooves.

[0010] According to the above technical means, the positioning slot provides positioning for the partition plate to be installed on the first steel casing or the second steel casing, ensuring the accuracy and stability of the partition plate installation on the first steel casing or the second steel casing, and preventing the partition plate from falling off due to mud disturbance during construction.

[0011] Furthermore, at least two positioning strips are formed on the inner sidewall of the first steel casing and / or the second steel casing, the two positioning strips are arranged parallel to each other, and the positioning groove is formed between the two positioning strips.

[0012] According to the above-mentioned technical means, the positioning groove is formed by the positioning strip, which not only realizes the positioning of the partition plate when it is installed on the first steel casing or the second steel casing, but also strengthens the first steel casing and / or the second steel casing, improves the strength of the first steel casing and / or the second steel casing, and prevents the first steel casing and / or the second steel casing from deforming and being damaged during construction.

[0013] Furthermore, the partition plate is provided with a hanging lug, which is used to hang the partition plate on the first steel casing or the second steel casing.

[0014] According to the above technical means, the hanging ear provides support for the partition plate to be hung on the first steel casing or the second steel casing. At the same time, the hanging ear has a simple structure, making the partition plate easy to assemble and disassemble.

[0015] Furthermore, two hanging ears are formed on the partition plate, and the two hanging ears are respectively located on opposite sides of the partition plate.

[0016] According to the above-mentioned technical means, the two hanging ears can provide balanced support for the installation of the partition plate, prevent the partition plate from tilting or twisting due to uneven force during construction, and ensure the stability of the partition plate installation.

[0017] Furthermore, a lifting ring is formed on the partition plate, which is used for external instruments to lift the partition plate.

[0018] According to the above-mentioned technical means, the use of external instruments to lift the partition plate through the lifting ring ensures the stability of the partition plate transportation process and guarantees the safety of the partition plate transportation process.

[0019] Furthermore, the flow guiding assembly includes a flow guiding pipe and a valve. The two ends of the flow guiding pipe are respectively installed on the side walls of the first steel casing and the second steel casing to connect the first steel casing and the second steel casing. The valve is installed at the end of the flow guiding pipe to control the flow direction of the mud in the flow guiding pipe.

[0020] According to the above-mentioned technical means, the valve can accurately control the flow direction of the mud in the guide pipe, so that the mud can flow in different directions in the guide pipe during the construction of the first steel casing and the second steel casing, so as to meet the construction requirements; at the same time, the valve and the guide pipe can prevent the mud from leaking during the construction process and reduce the risk of construction accidents.

[0021] Furthermore, the distance between the guide pipe and the top of the first steel casing or the second steel casing is 1m.

[0022] According to the above technical means, a space for mud level changes is reserved between the guide pipe and the top of the first steel casing or the second steel casing to prevent mud from overflowing from the top of the first steel casing or the second steel casing during construction.

[0023] Furthermore, it also includes a steel platform, which is disposed on the outer side of the top of the first steel casing and / or the second steel casing, for supporting external instruments so that the external instruments can excavate the sediment inside the first steel casing and / or the second steel casing.

[0024] According to the above-mentioned technical means, the steel platform provides a stable bearing surface for external instruments, preventing the construction difficulty of external instruments from increasing due to lack of stable support, thereby improving construction efficiency; at the same time, the steel platform can also provide support for the first steel casing and / or the second steel casing, preventing the first steel casing and / or the second steel casing from shifting during construction.

[0025] The beneficial effects of this utility model are as follows:

[0026] When constructing the first steel casing, the second steel casing is used as a mud pool for mud circulation, and when constructing the second steel casing, the first steel casing is used as a mud pool for mud circulation. This eliminates the need for an additional mud pool, reducing construction costs and making it economical. The flow direction of the mud between the first and second steel casings is controlled by the flow guiding component, making it highly adaptable. At the same time, this solution has a simple structure, is convenient to construct, and has high construction efficiency. Attached Figure Description

It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0036] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0037] This embodiment provides, as follows: Figures 1 to 5 The diagram illustrates a mud circulation structure for underwater pile casings, used for mud circulation during the construction of two adjacent underwater piles. It includes a first steel casing 100, a second steel casing 200, and a flow guiding component 300. The first steel casing 100 and the second steel casing 200 are used for the construction of two adjacent underwater piles, respectively. The flow guiding component 300 connects the first steel casing 100 and the second steel casing 200 and is configured to control the flow of mud between the first steel casing 100 and the second steel casing 200. The system includes a mud pump 400 and a mud pipe 500, with both ends of the mud pipe 500 located inside the first steel casing 100 and the second steel casing 200, respectively, to connect the first steel casing 100 and the second steel casing 200. The mud pump 400 is installed at one end of the mud pipe 500 to pump the mud inside the first steel casing 100 to the second steel casing 200 through the mud pipe 500, or to pump the mud inside the second steel casing 200 to the first steel casing 100 through the mud pipe 500.

[0038] When constructing cast-in-place piles, a first steel casing 100 and a second steel casing 200 are installed on the riverbed. During construction within the first steel casing 100, one end of the mud pipe 500, equipped with a mud pump 400, is installed inside the second steel casing 200, and the other end is installed inside the first steel casing 100. During construction, the flow guiding component 300 is opened to allow the mud inside the first steel casing 100 to flow to the second steel casing 200. Simultaneously, the mud pump 400 is opened to allow the mud inside the second steel casing 200 to flow through the mud pipe 500 to the first steel casing. 100; When construction is required along with the second steel casing 200, the mud pipe 500 and the mud pump 400 are swapped, and the flow guiding component 300 is opened so that the mud in the second steel casing 200 can flow to the first steel casing 100 through the flow guiding component 300. At the same time, the mud pump 400 is opened so that the mud in the first steel casing 100 can flow to the second steel casing 200 through the mud pipe 500. The flow guiding component 300, the mud pump 400 and the mud pipe 500 work together to realize the circulation of mud in the adjacent first steel casing 100 and second steel casing 200.

[0039] In this embodiment, the second steel casing 200 is used as a mud pool for mud circulation during the construction of the first steel casing 100, and the first steel casing 100 is used as a mud pool for mud circulation during the construction of the second steel casing 200. This eliminates the need for an additional mud pool, reducing construction costs and making it economical. The flow direction of the mud between the first steel casing 100 and the second steel casing 200 is controlled by the flow guiding component 300, making it highly adaptable. At the same time, this solution has a simple structure, is convenient to construct, and has high construction efficiency.

[0040] Preferably, in this embodiment, a perforating hammer is used to scour the riverbed to construct the interior of the first steel casing 100 or the second steel casing 200. During construction, the end of the mud pipe 500 away from the mud pump 400 is located near the perforating hammer to better deliver the mud to the perforating hammer.

[0041] like Figure 1 and Figure 2As shown, this embodiment also includes a partition plate 600, which is installed inside the first steel casing 100 or the second steel casing 200 for rapid sedimentation. A flow guiding assembly 300 and a mud pump 400 are located on opposite sides of the partition plate 600. When the flow guiding assembly 300 guides the mud from the first steel casing 100 to the second steel casing 200, or vice versa, the partition plate 600 intercepts the slag in the mud, causing it to settle rapidly. This further enables the mud pump 400 on the other side of the partition plate 600 to extract the upper mud, ensuring smooth mud circulation during construction. Specifically, the partition plate 600 has a mud inlet on one side and the mud pump 400 is located on the other side. When the mud enters the first steel casing 100 or the second steel casing 200, it needs to flow from the bottom to the other side due to the obstruction of the partition plate 600. The installation of the partition plate 600 has a good effect on slag separation and sedimentation.

[0042] like Figure 3 and Figure 4 As shown, in this embodiment, the inner sidewalls of the first steel casing 100 and / or the second steel casing 200 are formed with positioning grooves 110, and the side of the partition plate 600 is installed in the positioning grooves 110. The positioning grooves 110 provide positioning for the partition plate 600 to be installed on the first steel casing 100 or the second steel casing 200, ensuring the accuracy and stability of the partition plate 600 on the first steel casing 100 or the second steel casing 200, and preventing the partition plate 600 from falling off due to mud disturbance during construction.

[0043] like Figure 4 As shown, in this embodiment, at least two positioning strips 120 are formed on the inner sidewalls of the first steel casing 100 and / or the second steel casing 200. The two positioning strips 120 are arranged parallel to each other, and a positioning groove 110 is formed between the two positioning strips 120. The positioning groove 110 formed by the positioning strips 120 not only realizes the positioning of the partition plate 600 when it is installed on the first steel casing 100 or the second steel casing 200, but also strengthens the first steel casing 100 and / or the second steel casing 200, improves the strength of the first steel casing 100 and / or the second steel casing 200, and prevents the first steel casing 100 and / or the second steel casing 200 from deforming and being damaged during construction.

[0044] Preferably, the inner sidewalls of the first steel casing 100 and / or the second steel casing 200 are formed with two positioning slots 110. Correspondingly, the inner sidewalls of the first steel casing 100 and / or the second steel casing 200 are formed with four positioning strips 120. Two positioning strips 120 form a positioning slot 110. The opposite sides of the partition plate 600 are respectively installed in the two positioning slots 110.

[0045] like Figure 5 As shown, in this embodiment, a hanging lug 610 is formed on the partition plate 600. The hanging lug 610 is used to hang the partition plate 600 on the first steel casing 100 or the second steel casing 200. The hanging lug 610 provides support for the partition plate 600 to be hung on the first steel casing 100 or the second steel casing 200. At the same time, the hanging lug 610 has a simple structure, making it convenient to assemble and disassemble the partition plate 600.

[0046] In this embodiment, two hanging ears 610 are formed on the partition plate 600, and the two hanging ears 610 are respectively located on opposite sides of the partition plate 600. The two hanging ears 610 can provide balanced support for the installation of the partition plate 600, prevent the partition plate 600 from tilting or twisting due to uneven force during construction, and ensure the stability of the partition plate 600 installation.

[0047] like Figure 5 As shown, in this embodiment, a lifting ring 620 is also formed on the partition plate 600. The lifting ring 620 is used for external instruments to lift and place the partition plate 600. Using external instruments to lift and place the partition plate 600 through the lifting ring 620 ensures the stability of the partition plate 600 during transportation and guarantees the safety of the partition plate 600 during transportation.

[0048] In other embodiments, a plurality of lifting rings 620 may be formed on the partition plate 600.

[0049] like Figure 1 and Figure 2 As shown, in this embodiment, the flow guiding assembly 300 includes a flow guiding pipe 310 and a valve 320. The two ends of the flow guiding pipe 310 are respectively installed on the side walls of the first steel casing 100 and the second steel casing 200 to connect them. The valve 320 is installed at the end of the flow guiding pipe 310 to control the flow direction of the mud within the flow guiding pipe 310. The valve 320 can precisely control the flow direction of the mud within the flow guiding pipe 310, allowing the mud to flow in different directions within the flow guiding pipe 310 during construction within the first steel casing 100 and the second steel casing 200, thus meeting construction requirements. Simultaneously, the valve 320 and the flow guiding pipe 310 can prevent mud leakage during construction, reducing the risk of construction accidents.

[0050] Preferably, valves 320 are installed at both ends of the guide pipe 310. The two valves 320 simultaneously control the flow direction of the mud in the guide pipe 310, resulting in better control.

[0051] In this embodiment, the distance between the guide pipe 310 and the top of the first steel casing 100 or the second steel casing 200 is 1m. Space is reserved between the guide pipe 310 and the top of the first steel casing 100 or the second steel casing 200 to allow for changes in the mud level, preventing mud from overflowing from the top of the first steel casing 100 or the second steel casing 200 during construction.

[0052] like Figure 1 and Figure 2 As shown, this embodiment also includes a steel platform 700, which is disposed on the top outer side of the first steel casing 100 and / or the second steel casing 200. The steel platform 700 supports external instruments, enabling them to excavate sediment from within the first steel casing 100 and / or the second steel casing 200. The steel platform 700 provides a stable bearing surface for the external instruments, preventing increased construction difficulty due to lack of stable support and thus improving construction efficiency. Simultaneously, the steel platform 700 also provides support for the first steel casing 100 and / or the second steel casing 200, preventing displacement of the first steel casing 100 and / or the second steel casing 200 during construction.

[0053] When the punch hammer is used to work inside the first steel casing 100 or the second steel casing 200, a large amount of sediment will be generated. When too much sediment accumulates inside the first steel casing 100 or the second steel casing 200, hindering the mud circulation between the first steel casing 100 and the second steel casing 200, construction should be suspended, the partition plate 600 should be lifted out, and the sediment should be removed using external tools. After cleaning, the partition plate 600 should be lifted back into the first steel casing 100 or the second steel casing 200, and construction should continue until the construction is completed.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
