Abstract
Description
Technical Field
[0001] This utility model relates to the field of soft soil foundation treatment technology, and in particular to a pressurized drainage integrated air jet drainage pipe. Background Technology
[0002] Many deep, soft soils in coastal areas must be treated before they can be used as foundations for urban buildings and municipal infrastructure. Drainage consolidation methods, due to their cost advantages and uniform treatment effects, are widely used in coastal soft soil foundation treatment projects. Existing vacuum drainage consolidation methods generally use drainage boards as vertical drainage bodies. These boards only have the single function of transferring upper vacuum negative pressure to the deep soil and allowing water in the soil to flow upwards. Therefore, problems such as insufficient deep vacuum, gradual clogging of the drainage boards, and low drainage consolidation efficiency are frequently encountered in use. Current projects use pressurized vacuum preloading methods, inserting pressurization pipes into the soil on top of existing vertical drainage boards. Air is injected into the soil through these pipes to increase pressure and promote drainage from the drainage boards. However, the pressurization pipes are separate from the drainage boards, the function of each individual pipe is still relatively limited, and the pressurized gas cannot directly penetrate the soil to promote drainage from the drainage boards. Utility Model Content
[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an integrated pressurized drainage air jet drainage pipe, which can realize the functions of pressurizing and jetting into the soil and draining water, thereby improving the functionality of the vacuum preloaded vertical drainage body.

[0025] refer to Figures 1 to 4 This invention describes a pressurized drainage integrated air jet drain pipe according to an embodiment of the present invention.
[0026] like Figures 1 to 4As shown, the integrated pressurized and drained air jet drain pipe according to an embodiment of the present invention includes: a pressurized air pipe 1, which is cylindrical and has multiple cross-sections arranged along its length. Each cross-section has multiple nozzles 3 evenly distributed around the circumference of the pressurized air pipe 1. The nozzles 3 connect the interior of the pressurized air pipe 1 to the external environment, and the upper end of the pressurized air pipe 1 is connected to a pressurized gas pipeline; an outer wall drain channel 2, which is located on the outside of the pressurized air pipe 1. A water-permeable filter membrane 4 is provided on the outer surface of the outer wall drain channel 2, and the upper end of the outer wall drain channel 2 is connected to a vacuum drain pipeline; a sealing shoe 5, which is located at the bottom of the pressurized air pipe 1 and the outer wall drain channel 2; and a water collecting head 6, which is located at the top of the outer wall drain channel 2.
[0027] This integrated pressurized drainage air jet pipe combines pressurized air pipe 1 and external wall drainage channel 2, integrating pressurization and drainage functions into a single pipe. It occupies the space of an existing drainage board, allowing for air jet pressurization into the soil without affecting drainage at that point. This facilitates the rational layout of functional vertical drainage systems and reduces the need for repeated pipe and board installations. The air jet function also helps clear blockages around the drainage board, addressing the current problems of single-function and low drainage efficiency in vertical drainage systems.
[0028] The partition 202 of the outer wall drainage channel 2 is integrally thermoplastic molded with the pressurized air pipe 1. This can be achieved by only changing the injection mold, without the need for additional processes, which is beneficial for production cost control.
[0029] The water collection head 6 is installed by fitting it into the outer wall of the pressurized air pipe 1 and wrapping the top of the external drainage channel, which allows for convenient and quick water collection at the top of the device and separation of the top water and air pipelines. The water collection chamber 603 is enclosed by the inner wall of the stop platform 602, the inner wall of the top plate of the outer shell 601, the top surface of the external drainage channel 2, and the outer wall of the pressurized air pipe 1, which has a high material utilization rate and is easy to install.
[0030] The bottom sealing boot 5 has an outer cover 501 and a sealing ring 504, which prevents soil particles and water from entering the cavity at the bottom of the pipe and blocking the external drainage channel. At the same time, the outer wall of the inner tube 502 of the sealing boot 5 has three reverse teeth 505, which prevents the inner tube 502 of the sealing boot 5 from being easily pushed out by the air pressure of the pressurizing air pipe 1 after it is inserted into the pressurizing air pipe 1.
[0031] like Figure 1 As shown, the integrated pressurized and drained air jet pipe consists of a pressurized air pipe 1, an outer wall drainage channel 2, a nozzle 3, a filter membrane 4, a sealing shoe 5, and a water collection head 6. The pressurized air pipe 1 has nozzles 3 installed on its wall, and multiple cross-sections with nozzles 3 are arranged along the length of the pressurized air pipe 1. Each cross-section has 4, 6, or 8 nozzles 3 installed.
[0032] like Figure 2 As shown, the outer side of the booster pipe 1 has an outer wall drainage channel 2. The outer surface of the outer wall drainage channel 2 is provided with a water-permeable filter membrane 4. The outer wall drainage channel 2 has multiple drainage chambers 201. The drainage chambers 201 are arranged in a ring along the outer wall of the booster pipe 1. The partition 202 of the drainage chamber 201 is integrally thermoplastic molded with the booster pipe 1.
[0033] like Figure 4 As shown, the sealing shoe 5 is located at the bottom of the integrated pressurization and drainage air jet pipe, and includes an outer cover 501, an inner tube 502, a conical bottom 503, and a sealing ring 504. The outer wall of the inner tube 502 is provided with three reverse teeth 505, and the sealing ring 504 is located between the outer cover 501 and the inner tube 502, as well as at the bottom of the pressurization air pipe 1 and the outer wall drainage channel 2.
[0034] like Figure 3 As shown, the water collection head 6 is located at the top of the integrated pressurized and drained air jet pipe, and includes a housing 601, a stop platform 602, a water collection chamber 603, and a water outlet 604. The diameter of the stop platform 602 is smaller than the inner diameter of the housing 601, but larger than the outer diameter of the pressurized air pipe 1. The outer wall drainage channel 2 is located at the top of the structure, lower than the height of the pressurized air pipe 1, and in contact with the stop platform 602. The space enclosed by the inner wall of the stop platform 602, the inner wall of the top plate of the housing 601, the top surface of the outer wall drainage channel 2, and the outer wall of the pressurized air pipe 1 forms the water collection chamber 603. A circular pipe outlet 604 is provided on the housing 601.
[0035] like Figures 1 to 4 As shown, this integrated pressurized and drained air jet pipe includes a pressurized air pipe 1, an outer wall drainage channel 2, nozzles 3, a filter membrane 4, a sealing shoe 5, and a water collection head 6. The pressurized air pipe 1 and the partition 202 of the outer wall drainage channel 2 are first integrally thermoplastic molded to form a basic pipe body with multiple jet-shaped partitions 202 surrounding the pressurized air pipe 1. Multiple cross-sections are taken along the length of the pressurized air pipe 1 for nozzle 3 installation, with each cross-section containing 4, 6, or 8 nozzles 3, symmetrically and evenly spaced along the circumference on the outer wall of the pressurized air pipe 1. An adhesive is applied to the outer edge of the partition 202 of the outer wall drainage channel 2 to adhere the filter membrane 4, wrapping the entire basic pipe body to form the finished pipe body. The sealing shoe 5 is integrally thermoplastic molded and includes an outer cover 501, an inner pipe 502, and a conical bottom 503. The water collection head 6 is integrally thermoplastic molded and includes a shell 601, a stop platform 602, and a water outlet 604.
[0036] Before the on-site installation of the integrated pressurized and drained air jet pipe, a sealing shoe 5 is installed at the bottom of the finished pipe body. A sealing ring 504 is placed between the outer cover 501 and the inner tube 502 of the sealing shoe 5. The outer diameter of the inner tube 502 of the sealing shoe 5 is equal to the inner diameter of the pressurized air pipe 1. Three reverse teeth 505 are provided on the outer wall of the inner tube 502. The inner tube 502 of the sealing shoe 5 is pressed into the bottom of the pressurized air pipe 1 to achieve the connection between the sealing shoe 5 and the finished pipe body. Only after the pressurized air pipe 1 is connected to the sealing shoe 5 can the next step of installing the integrated pressurized and drained air jet pipe be carried out.
[0037] The integrated pressurized drainage air jet pipe is installed in the soil to a specified depth using a pipe inserter with a sleeve. After the sleeve is removed, the top of the integrated pressurized drainage air jet pipe protrudes from the top surface of the foundation for a length of not less than 500mm, and the finished pipe body is then cut off. Preferably, the partition 202 of the outer wall drainage channel 2, which is 150-200mm long at the top of the integrated pressurized drainage air jet pipe, is removed, leaving this section of the pressurized air pipe 1, and the cut surface is kept flat. The pressurized air pipe 1 is inserted into the water collection head 6 from the top until the outer wall drainage channel 2 contacts the stop platform 602 of the water collection head 6, and the outer shell 601 encloses a section of the outer wall drainage channel 2, forming a water collection cavity 603 surrounded by the inner wall of the stop platform 602, the inner wall of the top plate of the outer shell 601, the top surface of the outer wall drainage channel 2, and the outer wall of the pressurized air pipe 1. The water collection head 6 can rotate around the pressurized air pipe 1 to adjust the direction of the outlet 604. The pressurization pipe 1 is connected to the pressurization gas pipeline on the top surface of the foundation, and the outer wall drainage channel 2 is connected to the vacuum drainage pipeline through the outlet 604 of the water collection head 6 on the top surface of the foundation.
