Description

Technical Field

[0001] The utility model belongs to the technical field of water enclosures and relates to a dual-purpose construction soft enclosure. Background Art

[0002] With the progress of society and the continuous development of the economy, important water resources such as urban rivers, lakes, streams, and reservoirs have become increasingly polluted. Large amounts of nitrogen and phosphorus pollutants, such as industrial wastewater and domestic sewage, have entered these water bodies, leading to the gradual collapse of aquatic ecosystems, a decline in the water's self-purification capacity, and severe eutrophication. This not only damages the existing ecological environment but also significantly impacts the production and daily lives of urban residents.

[0003] At present, water body restoration is mainly divided into in-situ restoration and ex-situ restoration. In-situ restoration refers to the use of specific technical means to repair the original regional environment of the river; while ex-situ restoration is to transfer pollutants to other spatial areas for restoration. Compared with in-situ restoration, ex-situ restoration not only increases various costs, but also easily causes secondary pollution during the transfer process. Therefore, in-situ restoration technology is usually used to repair the water environment.

[0004] In previous in-situ remediation efforts, effective pollution source control was paramount, making effective interception crucial. PVC soft enclosures, a commonly used type of enclosure, can effectively create a closed area, isolate pollution sources, or intercept and purify existing water. However, existing soft enclosures typically use a suspended counterweight to seal the lower end. External interference can directly affect the enclosure's sealing properties. Therefore, a more comprehensive soft enclosure technology is urgently needed to ensure a tight seal at construction or water remediation sites. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems existing in the prior art and to provide a dual-purpose construction soft enclosure.

[0031] In order to more clearly demonstrate the technical content of the present invention, it is further described below in conjunction with specific embodiments.

[0032] like Figure 1-4 As shown, the utility model mainly provides a dual-purpose construction soft enclosure, including a soft enclosure main body 1 for separating the construction area from the outside world and a covering anchor 2 for counterweight reinforcement; the soft enclosure main body 1 includes a plurality of main geotextiles 11 and a galvanized steel pipe 12; wherein, the plurality of main geotextiles 11 are connected by galvanized steel pipes 12, and a covering anchor 2 is also connected to the bottom end of the soft enclosure main body 1.

[0033] In this embodiment, the main geotextiles 11 are all made of PVC material, which has the characteristics of light weight, low cost, safety and environmental protection, no pollution to the environment, and corrosion resistance. The main geotextiles 11 are combined with the galvanized steel pipes 12 to form a multi-section structure, which is convenient for the transportation, disassembly and maintenance of materials. During the process, the main geotextiles 11 are arranged and combined to achieve isolation and blocking of pollution sources. Specifically:

[0034] Stainless steel collars 13 are provided at both ends of the main geotextile 11, wherein the size of the stainless steel collars 13 matches the size of the galvanized steel pipes 12, so that several main geotextiles can be connected through the galvanized steel pipes 12; in this embodiment, the stainless steel collars 13 are set at different heights. During the process, the galvanized steel pipes 12 only need to pass through the stainless steel collars 13 at different positions on the two main geotextiles to connect and fix several main geotextiles 11; in order to increase the stability of the fixation between the galvanized steel pipes 12 and the stainless steel collars 13, a circle of plastic collars 14 is further provided inside the stainless steel collars 13 for reinforcement, thereby reducing the damage caused by excessive friction between the galvanized steel pipes and the stainless steel collars due to water level fluctuations; in this embodiment, a plurality of galvanized steel pipes 12 are provided, so as to meet the connection and fixation of several main geotextiles 11; at the same time, the number of main geotextiles 11 can also determine the required connection length according to actual needs to meet the needs of different water environments.

[0035] In this embodiment, the galvanized steel pipe 12 adopts a DN20 steel pipe with a wall thickness of 2.8 mm and is galvanized for corrosion protection, thereby reducing oxidation corrosion caused by the steel pipe surface being immersed in seawater for a long time and increasing its service life; the height of the galvanized steel pipe 12 can be adjusted according to actual conditions to meet the needs of different water environments; in addition, the galvanized steel pipe 12 is preferably a cylindrical structure, which can be easily passed through the stainless steel ring; the height of the galvanized steel pipe above the water surface is higher than the highest water level line of the construction river channel, and the submerged length of the galvanized steel pipe part in contact with the bottom surface is not less than 0.8 m, thereby ensuring the stability of the soft enclosure body and preventing the soft enclosure from collapsing and being damaged due to the impact of water flow; at the same time, in order to facilitate the insertion of the galvanized steel pipe 12 into the soil structure of the bottom surface of the water, one end of the galvanized steel pipe can be set to a pointed structure (not clearly drawn in the figure).

[0036] In this embodiment, in order to increase the sealing performance of the soft enclosure body 1, the two main geotextiles 11 connected to the galvanized steel pipe 12 are sealed; specifically:

[0037] An outer geotextile 3 is provided at the connection between the galvanized steel pipe 12 and the main geotextile 11. The outer geotextile 3 also adopts the same PVC material as the main geotextile 12. By arranging a parent-child Velcro 15 between the outer geotextile 3 and the main geotextile 11 (a circle of Velcro is provided on the outer geotextile, and a matching parent Velcro is provided on the main geotextile), they are pasted and fixed, thereby achieving a simple sealing effect, reducing the problem of pollutants passing through the gap, and providing a pollution interception effect; at the same time, the structure of the parent-child Velcro 15 can also effectively solve the problem that local soft enclosures cannot be replaced due to traditional integrated structures, and has the advantages of easy installation and disassembly, simple operation, etc.

[0038] In this embodiment, the lower end of the soft enclosure body 1 is provided with a covering anchor 2 for counterweight reinforcement; the covering anchor 2 is formed by wrapping the lower end of the main geotextile with a counterweight block 21, filling it as an anchor, and finally backfilling and covering it with soil; the covering anchor formed is filled into the pre-dug trench and then backfilled with soil and compacted, thereby increasing the fixing stability; its buried covering anchor structure can allow the soft enclosure body to avoid external interference factors to the greatest extent, and minimize the sealing problem caused by the swing of the main geotextile due to water flow fluctuations in the water (the covering anchor and the main soil block cloth are wrapped as a whole or in sections, and can be divided into different structures according to dry land construction and underwater construction to meet the use under different conditions).

[0039] In this embodiment, the main geotextile block extends to a length of about 2.5m, and the counterweight block 21 is a rectangular structure of 0.4*0.5m, filled with long strips of coarse sand 22; its integrated structure of covering soil and anchoring 2 can provide better sealing and stability than the existing counterweight method, and can effectively avoid leakage problems in soft enclosures caused by the impact of river water flow.

[0040] In this embodiment, when the device is used for underwater construction, the buoy 4 can be connected to the soft enclosure body 1, and the buoy 4 is set at the upper end of the soft enclosure body 1, and is set to be detachably connected to the soft enclosure body 1 (the buoy is fixed to the soft enclosure body by a device such as a binding / tie or a lock); the buoy 4 includes a floating geotextile 41 and a floating block 42, and the floating block 42 is surrounded and wrapped by the floating geotextile 41; preferably, the floating block 42 adopts a cylindrical structure with a diameter of 50 mm. The buoy 4 is mainly used to straighten the soft enclosure body during underwater construction (because the stainless steel ring may move up and down, causing the soft enclosure body to drop and thus affect the sealing effect); when this technology is applied to dry land construction, this component may not be provided.

[0041] The method of using the utility model is as follows: when using, first measure and lay out the lines, then determine the number of segmented geotextiles according to the actual construction space requirements, and lay galvanized steel pipes between adjacent main geotextiles as supports for construction soft enclosures, select a suitable number of small segments of main geotextile blocks for installation, and subsequently adjust the number and size of the main geotextile blocks according to the construction progress.

[0042] It should be noted that: the utility model adopts the form of segmented PVC main body geotextile and the lower end covering and anchoring structure. Compared with traditional soft enclosures, it has the advantages of simple structure, easy replacement, good sealing and wide applicability. Its multi-section geotextile splicing structure can replace damaged PVC geotextile blocks in a targeted manner, and the enclosure length can be increased at any time according to actual needs to meet the use in different scenarios. In addition, the buried soil covering and anchoring structure can allow the soft enclosure to avoid external interference factors to the greatest extent, and minimize the sealing problems caused by the swing of PVC geotextile due to water flow fluctuations in the water.
