Description

Technical Field

[0001] This invention relates to the field of flood control components, specifically to a pressure hose expansion seal waterproof and flood control component. Background Technology

[0002] With the advancement of science and technology and the emergence of new materials, the design goal of this pressure hose expansion sealing waterproof flood control component is to use new technologies and materials to design and manufacture flood control walls on river embankments more quickly and effectively, thereby preventing floods from overflowing the flood control embankment and minimizing flood disasters.

[0003] The Chinese invention patent application publication number CN107208390A discloses an improved containment dam in which multiple flexible containment tubes are stacked in a pyramid shape to form a dam section for fluid containment, thereby creating a temporary diversion dam.

[0004] The applicant submitted two patent applications to the State Intellectual Property Office for flood control components, with patent numbers 202320013239.7 and 202320705232.1, both of which have been granted. Through testing, it was found that because the cement slot base is constructed underground, various adverse factors such as rainwater can cause settlement or displacement of the cement slot. In such cases, the steel locking buckle cannot maintain a horizontal alignment with the cement slot base, and the waterproof fabric cannot be properly secured and sealed within the cement slot, easily leading to leakage and affecting the flood control effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a pressure hose expansion sealing waterproof and floodproof component that can effectively block water leakage, in order to address the above-mentioned shortcomings of the existing technology.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A pressure hose expansion seal waterproof and floodproof assembly, comprising:

[0008] The base is embedded in the ground and has a semi-circular or semi-circular groove provided on it, with the opening of the semi-circular or semi-circular groove protruding above the ground.

[0009] Waterproof fabric, which is laid out before a flood and whose bottom is fixed in a semi-circular or semi-circular groove in the base.

[0010] A pressure hose is laid in the semi-circular or semi-circular groove of the base before the flood arrives. After the pressure hose is injected with the medium, it expands and tightly fixes the bottom of the waterproof cloth in the semi-circular or semi-circular groove of the base.

[0011] In a preferred embodiment of the present invention, it further includes: a guardrail that is installed on the rear side of the water-facing surface of the base in a detachable or fixed manner and extends upward; the remaining part of the waterproof cloth is laid and fixed on the guardrail.

[0012] In a preferred embodiment of this utility model, a drainage hole is provided on the side wall of the base on the water-facing side. The drainage hole connects the semi-circular groove or the semi-circular groove to the outside world to drain the rainwater from the semi-circular groove or the semi-circular groove.

[0013] In a preferred embodiment of this utility model, the semi-circular or semi-circular slot is disposed on the top wall or side wall of the base.

[0014] In a preferred embodiment of this utility model, the base is divided into several sections.

[0015] In a preferred embodiment of this utility model, when not resisting floods, a cover plate is placed on the base to cover the semi-circular or semi-circular slot.

[0016] In a preferred embodiment of this utility model, the guardrail is installed in a detachable manner on the rear side of the water-facing side of the base as follows: a plurality of buckle seats are provided on the ground surface on the rear side of the water-facing side of the base, and the guardrail is installed on the rear side of the water-facing side of the base through these buckle seats when in use.

[0017] In a preferred embodiment of the present invention, a first sealing buckle and a second sealing buckle are respectively provided at both ends of the pressure hose to seal both ends of the pressure hose; or the two ends of the pressure hose are sealed.

[0018] In a preferred embodiment of the present invention, a first fixed connector is provided at one end of the pressure hose, a one-way check valve is installed on the first fixed connector, a first union is installed on the one-way check valve, and the first union is connected to the main delivery pipeline for delivering the medium into the pressure hose; a second fixed connector is provided at the other end of the pressure hose, a pressure relief valve is installed on the second fixed connector, and a second union is installed on the pressure relief valve.

[0019] In a preferred embodiment of the present invention, the pressure hose is divided into several sections. The first union on the previous section of the pressure hose and the second union on the next section of the pressure hose are connected by a branch delivery pipe. The first union on the last section of the pressure hose is connected to the main delivery pipe.

[0020] By adopting the above technical solution, this utility model uses a pressure hose that expands after being filled with the medium to fix the waterproof cloth on the base, which can effectively block water leakage.

[0021] This invention utilizes a pressure-resistant flexible hose equipped with a one-way check valve and a pressure relief valve, all sealed tightly. A pressurized fluid medium, either water or gas, is introduced into the hose (water is preferred for riverbank flood control; pressurized gas generates buoyancy, which can damage the stability of the cement groove base when the riverbank soil is soft). This pressurizes and expands the hose, compressing the waterproof fabric laid within the semi-circular or semi-circular groove of the base, achieving a tight seal.

[0022] Because the pressure generated by the fluid medium inside the input pressure hose expands and pushes outwards evenly, and the cavity size of the semi-circular or large semi-circular groove of the base is smaller than the maximum size of the pressure hose after expansion, the waterproof cloth will be tightly and seamlessly squeezed into the semi-circular or large semi-circular groove of the base, forming a very firm whole, thereby achieving the function of blocking water leakage.

[0023] In particular, the pressure hose can bend with the slight bending of the semi-circular or semi-circular groove of the base, exhibiting excellent plasticity. Furthermore, a single pressure hose can achieve a sealing length of 1-200 meters, and its small size, light weight, tight sealing, and simple and quick operation offer outstanding advantages.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] See Figure 1The figure shows a pressure hose expansion sealing waterproof and flood-proof component, including a base 100, which is prefabricated in a prefabrication plant using steel or concrete according to design requirements. The main design feature is a semi-circular or larger semi-circular groove 110 prefabricated in the middle of the top of the base 100. An opening 120, smaller than the diameter of the semi-circular or larger semi-circular groove 110, is left at the top of the groove, forming a semi-circular or larger semi-circular groove 110 with a large internal space and a narrow opening. This effectively secures the expanded pressure hose 400, preventing slippage. Additionally, the semi-circular or larger semi-circular groove 110 can be designed on the side wall of the base 100 according to the terrain requirements.

[0030] A drainage hole 130 is reserved on the middle side of the semi-circular or semi-circular groove 110 along the length of the water-facing surface of the base 100. The water inlet of the drainage hole 130 can be set at the bottom of the semi-circular or semi-circular groove 110. The drainage hole 130 connects the semi-circular or semi-circular groove 110 with the outside, which can effectively remove and prevent soil splashing into the semi-circular or semi-circular groove 110 caused by daily rainwater impact, thus preventing accumulation and blockage.

[0031] In use, the prefabricated base 100 is placed in the designed trench in advance at key locations where flood prevention is required. The outlet end of the drainage hole 130 is kept at least 3 cm above the ground for daily maintenance to prevent soil blockage. The joint between two bases 100 is filled seamlessly with cement, and then the excavated soil is backfilled and compacted. The base 100 is integrated with the ground to become a long-lasting outdoor flood protection component. When not resisting floods, a cover plate (not shown in the figure) is placed on the base 100 to cover the semi-circular or semi-circular slot 110.

[0032] When using underground warehouses and cement roads in urban and rural areas, the prefabricated base 100 is fixed with cement 5 cm below the ground surface. The drain outlet of the drainage hole 130 of the base 100 is connected to the sewer. A safety cover must be installed on the top of the slot for easy passage. The cover should be removed when flood prevention is needed.

[0033] A guardrail 200 is installed within 0.5 meters or 1 meter behind the water-facing side of the base 100, using either a detachable or fixed method; the guardrail 200 extends upwards. The structure of the guardrail 200 can refer to the design scheme of crash barriers on highways, with some grilles added in the middle of the guardrail. The height of the guardrail 200 is determined according to the design flood control height requirements; this guardrail 200 constitutes a sturdy waterproof wall on the riverbank.

[0034] The guardrail 200 is installed in a detachable manner within 0.5 meters or 1 meter behind the water-facing side of the base 100, as follows:

[0035] Several steel clip seats 210 are installed on the ground within 0.5 meters or 1 meter behind the water-facing side of the base 100. When the guardrail 200 is to be used, it needs to be installed in advance on the river embankment of the distant flood control target, and then installed within 0.5 meters or 1 meter behind the water-facing side of the base 100 through these steel clip seats 210. Compact steel clip bases 210 are installed in the streets between urban and rural areas and in various underground warehouse passages to provide fixed support for the movable guardrail 200 without affecting the passage of pedestrians and vehicles.

[0036] When a flood is imminent, take out the stock of waterproof fabric 300 material, quickly stretch it out and lay it flat on the semi-circular or semi-circular groove 110 of the base 100. First, lay the waterproof fabric 300 facing the water-facing side and tuck the bottom of the waterproof fabric 300 into the semi-circular or semi-circular groove 110 of the base 100, leaving 10 cm of the waterproof fabric 300 outside the semi-circular or semi-circular groove 110 of the base 100 to prevent the waterproof fabric 300 from slipping and make it more secure.

[0037] Next, immediately unfold and straighten the pressure hose 400 and insert it into the semi-circular or semi-circular groove 110 of the base 100, pressing it onto the waterproof cloth 300. Then, immediately connect the main delivery pipe 420 to input pressurized water. At the same time, open the pressure relief valve 410 at the other end to release the air in the pressure hose 400, and then close the pressure relief valve 410.

[0038] To connect multiple pressure hoses 400, connect adjacent pressure hoses 400 end to end. Connect one end of a branch delivery pipe 430 to the union 450 (the aforementioned first union) of the check valve 440 of the first pressure hose 400. Then connect the other end of this branch delivery pipe 430 to the union 460 (the aforementioned second union) of the pressure relief valve 410 of the second-to-last pressure hose 400. Continue in this manner. Open the pressure relief valve 410 of the first pressure hose 400, pressurize the main delivery pipe 420 with water to purge the air from all pressure hoses 400, and then close the pressure relief valve 410 of the first pressure hose 400.

[0039] When the water pressure in all pressure hoses 400 reaches the set value, pressurization will stop. After the pressurized water flow stops, each one-way check valve 440 will automatically close immediately as it will not be subjected to inward pressure. The automatic closure of each one-way check valve 440 prevents water pressure leakage from each pressure hose 400, maintaining the pressurized expansion state of each pressure hose 400 for a long time and ensuring a firm seal.

[0040] Each pressure hose 400, filled with pressurized water, immediately expands, firmly and seamlessly securing the waterproof fabric 300 into the semi-circular or semi-circular groove 110 along the water-facing side of the base 100. This completes the crucial step of sealing and waterproofing. After the seal is completed and inspected, the waterproof fabric 300 is turned over, laid flat on the ground, and loosened slightly before being hung on the guardrail 200 and secured, thus constructing a sturdy flood barrier.

[0041] The purpose of expanding and sealing the waterproof cloth 300 before turning it over and laying it flat is to cover the main delivery pipe 420 and several branch delivery pipes 430, which are connected to various pressure hoses 400, under the waterproof cloth 300 so that they are not affected by water flow and to protect the safe transportation of the main delivery pipe 420 and several branch delivery pipes 430.

[0042] The purpose of laying the waterproof cloth 300 flat on the ground is that when the water rises to the top of the waterproof cloth 300, the weight and pressure of the water will press the waterproof cloth 300 tightly against the ground and then push it outward until it is blocked by the guardrail 200.

[0043] If the tarpaulin 300 is tied too tightly and there is insufficient slack for loosening, it will be squeezed by the water flow and break before being blocked and protected by the guardrail 200, resulting in leakage. The main function of the tarpaulin 300 is to seal the water flow. When blocking the water flow, the ground and guardrail 200 bear the enormous pressure and provide support. The principle is the same as the phenomenon where a sewer grate is blocked by leaves and cannot drain water, or a sink funnel is blocked by rice grains and cannot drain water. The key technology of the expansion sealing and waterproofing of the guardrail 200, tarpaulin 300, and various pressure hoses 400 is to utilize these normally weak objects, which, under favorable conditions, can also have the important function of preventing leaks and blocking floods.

[0044] After completing the flood control task, shut off the pressure transmission source, remove the main transmission pipe 420 and several branch transmission pipes 430 from the pressure hose 400, open the pressure relief valve 410 on the pressure hose 400, and after the water pressure in the pressure hose 400 in the base 100 drops and releases, pull out the pressure hose 400 and coil it up, drain the water from the pressure hose 400, wrap it up, clean the waterproof cloth 300, and collect it all back into the warehouse for later use.

[0045] The 400 pressure hose expansion sealing flood control technology is designed to cope with the suddenness of flood control and disaster relief, the arduous task of containment, and the need for extremely short timeliness.

[0046] This invention, under ideal conditions and with skilled personnel, allows for the deployment of defenses along dikes thousands or even tens of thousands of meters long within a single day, significantly changing the passive nature of traditional flood control projects. It also explores new methods for applying new materials and technologies in the field of flood control.
