Sand layer water filter double plug squirting water taking method and manufacturing method thereof

The technical field to which the present invention pertains: the present invention is a method for manufacturing water in a sand layer of a sand bank with a double plug nozzle, and a method for manufacturing the equipment and equipment thereof, in particular, a double plug with a water spray function The water spray head (equipment) is placed in the water filter pipe, and then the double plug water jet head is pressurized to start the pipe plug at both ends of the water spray head, so that the water spray section between the two pipe plugs forms a high pressure water zone, and the high pressure water in the zone is The lower side of the filter water pipe and the water filtering hole at the bottom of the pipe are sprayed, so that the lower side of the pipe and the sand layer at the bottom of the pipe form a piping and lose the side friction force and the bottom supporting force, so that the pipe can sink due to gravity. In this way, the water is sprayed one by one to make all the sections of the whole filter water pipe sink to the same depth along the water conduit guide groove of the collecting well (equipment), and then repeat the above-mentioned spray-spraying operation to completely sink the whole filter water pipe to the required one. Depth to complete the construction of the water filter. Finally, after installing the relevant pumping and control equipment inside and outside the collection well, the project of taking water from the filter water pipe under the sand bank can be completed for people's livelihood, irrigation or aquaculture.

The prior art related to the present invention: the conventional method for taking water from the sand layer under the sand bank is usually taken by vertical drilling on the sand bank, by the horizontal pipe to collect water from the collecting well, and by the offshore to obtain the water and then diverting water from the pipeline to the shore or Dig trenches and bury horizontal pipes to collect water.

If the vertical drilling and water intake is taken on the sand bank, the well position should not be too close to the water edge of the sand bank to avoid erosion, and the depth of the abstract water layer, the thickness of the aquifer and the water collection range are limited by the slow filling of the free water cone surface of the groundwater level. The amount of water taken is not large. If the horizontal pipe is used to collect water from the collecting well, the horizontal pipe will be installed in the sand layer, because the sand layer will be more closely subjected to vibration, and the penetration depth of the horizontal pipe will not be deep, so that the water intake is limited. If the offshore waterworks are taken from the shore and then the water is diverted from the pipeline to the shore, the engineering cost is very large. Water is set off from the shore (using a water intake or a water caisson) to divert water. The water and water intake pipes are often damaged by the monsoon and typhoon winds and waves invading the shore. If the trench is buried in the bank and the horizontal pipe is used to take water, the trench wall will collapse when the trench is dug to the water level. Only the steel pile can protect the trench wall. However, the water seepage is difficult to stop during construction, so the horizontal pipe is buried deep. It can only be in the vicinity of the water level, so it can only be buried in the shallow layer but affected by the tidal water level. The water intake is not large and the water intake time is affected by the rising and falling tide. The depth of the water collecting pipe is shallow and its cover is insufficient, which is vulnerable to wind and waves. Corrosion damages the water intake pipe.

The invention has the following advantages: a water-removing method for spraying a water filter pipe with a double plug nozzle in a sand layer on the sand bank, and a device and a device manufacturing method thereof, as shown in Fig. 1 and Fig. 5, which have a water spray function The double plug water jet head (1) of the device is placed in the water filter pipe (7), and then the double plug water jet head is pressurized to start the pipe plug (11) at both ends of the water jet head, so that the water spray section between the two pipe plug sections (12) forming a high-pressure water zone, wherein the high-pressure jet (13c) of the zone is ejected from the lower side of the filter water pipe and the water filtering hole (73) at the bottom of the pipe, so that the lower side of the pipe and the sand layer at the bottom of the pipe form a pipe. Loss of side friction and bottom support force can cause the filter tube to sink due to gravity. After the whole filter water pipe is pressurized step by step to form a pipe plug, water is sprayed from the lower side of the water filter pipe and the bottom of the pipe to cause the water filter pipes of each section to sink to the same depth along the water filter pipe guide groove (20) of the water collecting well of the water collecting device. Then repeat the aforementioned sinking operation to completely sink the entire filter water pipe to the required depth. After the pumping and control equipment is installed in the collection well, the project to take water from the filter pipe under the sand bank is completed.

The traditional method of taking water from the sand layer on the shore of the sand is usually vertical drilling on the sand bank, horizontal pipe installation from the collecting well, water supply from the offshore, water diversion from the pipeline to the shore, or trenching and horizontal crossing on the sand bank. Take water. Vertically drilling water on the sand bank, the water intake is limited due to the depth of the taken water layer, the thickness of the aquifer and the catchment range being limited by the slow filling of the free water cone surface of the groundwater; the present invention is a horizontal water filter pipe under the sand layer in the water Water is taken in the sand layer, so the water intake does not have the effect of slow filling of the vertical water taper surface. Therefore, the water intake of the horizontal filter water pipe can be provided by the source of the water-bearing sand layer.

If the horizontal pipe is used for collecting water from the collecting well, the horizontal pipe will be installed in the sand layer, because the sand layer will be more closely subjected to vibration, and the penetration depth of the horizontal pipe will not be deep, so that the water intake is limited or sometimes impossible to construct; The invention is characterized in that the filter water pipe is horizontally placed on the sand bank, and then the double plug water spray head is placed in the water filter pipe, and the water filter pipe is buried to the depth below the water level surface by depth by way of spray and sink, so the filter water pipe is surrounded. The sand layer is not tight, and the length of the water filter pipe is limited only by the width of the sand bank and the thickness of the underwater protective sand layer after the sinking. Therefore, the water intake of the water filter pipe is almost unlimited.

If the offshore waterworks are taken from the shore and then the water is diverted from the pipeline to the shore, in addition to the huge engineering cost, the waterworks are set off from the shore (using the water intake or water caisson), and the water diversion channel is buried by the sandbank to the shore. The monsoon and typhoon winds and waves invade the shore and are damaged; the invention directly takes water from the lateral filter water pipe under the sand layer on the shore of the sand bank, and the filter water pipe is protected by the sand layer under the sand bank, as long as the depth of the water filter pipe is sufficient It is not damaged by the monsoon and typhoon winds and waves, so it can be safely supplied during monsoon and typhoon.

If the trench is buried in the bank and the horizontal pipe is used for water extraction, the trench wall will collapse when the trench is deep to the water level when the trench is digging in the water. Therefore, the horizontal pipe can only be buried near the water level, so the water intake is not large, and It is easy to be damaged by wind and waves and damages the water intake pipeline; the invention is to bury the filter water pipe lateral filter water pipe under the sand layer on the sand bank, and the depth of the buried water can be sprayed at a depth as needed and is not affected by the tidal level during construction. Influence, so the water intake is almost unlimited, and after completion, the water filter pipe is protected by the sand layer under the water level surface. As long as the depth of the water filter pipe is sufficient, it is not damaged by the monsoon and typhoon wind waves.

The invention relates to a water-removing method and a device for spraying and filtering a water filter pipe by using a double-spraying water jet in a sand layer on the sand bank side, and using the water-filling capacity of the sand layer under the sand bank after the water tank sprayed and buried is completed, and is matched with the water collecting well After installing the relevant pumping and control equipment inside and outside, it is possible to provide water in the filter water pipe under the sand bank to solve the aforementioned problems for people's livelihood, irrigation or aquaculture.

The solution is as shown in Fig. 1. The horizontal water filter pipe (7) can be placed on the sand bank according to the required diameter, depth and length to be placed in the water filter channel of the collecting well (2). 20), then put the double plug water jet head (1) with water spray function into the water filter pipe; then, as shown in Fig. 5, pressurize the double plug water jet head to start the pipe plug at both ends of the water spray head (11) ), the water spray section (12) between the two pipe plugs forms a high-pressure water zone, and the high-pressure water (13e) outside the steel cylinder of the zone is shielded by the upper rubber film (12a) of the spray zone, and the high-pressure jet (13c) is The lower side of the section of the filter water pipe and the water filter hole (73) at the bottom of the pipe are sprayed, so that the lower side of the pipe and the sand layer at the bottom of the pipe form a pipe and lose side friction and bottom support force. The water filter pipe is allowed to sink by gravity as shown in Fig. 1, and then the spray head is decompressed and moved to a length of about half of the water spray section to continue the spray operation. After the whole filter water pipe is pressurized step by step to form a pipe plug, the water is sprayed to the bottom of the water filter pipe to cause the water filter pipes of each section to sink to the same layer depth along the water filter pipe guide groove of the water collecting well; The entire filter water pipe is completely lowered to the required depth layer by layer to complete the spray pipe construction of the water filter pipe. Then, after matching the pumping and control equipment inside and outside the collecting well, the project of taking water by the local method under the sand bank is completed.

The working method of the present invention is as shown in FIG. 1 , FIG. 4 , FIG. 5 and FIG. 5A to FIG. 5C , and the double plug nozzle of the device is placed in the water filter pipe, and the high pressure water is placed in the water filter pipe at both ends of the water spray head. Forming a pipe plug (11), so that the water spray head (12) between the two pipe plugs forms a high-pressure water zone, and the upper rubber film (12a) of the water spray section on the side and top of the upper section is expanded to form a shadow block. The water in the steel cylinder is flowed from both ends and above, so that the high pressure water (13d) formed by the high pressure water (13d) in the steel cylinder and the high pressure water (13e) outside the steel cylinder can only be used in the lower part of the water conduit. The water filtering hole (73) on the side and the bottom of the pipe is sprayed, so that the lower side of the filter pipe and the sand layer at the bottom of the pipe form a pipe and sink, and then the whole filter pipe is pressurized step by step to form a pipe plug, and then the filter is filtered. The water spray at the bottom of the water pipe causes the water pipes of each section to sink to the same depth; repeating the above-mentioned spray-spreading operation causes the whole filter water pipe to sink down to the required depth along the guide pipe of the water collecting well to achieve the step by step. Layer depth spray water filter works.

The water collecting well (2) of the device of the present invention is provided with a water conduit guiding groove (20), a sand blocking steel box (22) and a sand blocking plate assembly (21) as shown in Fig. 6 and Figs. 6A to 6G. The results are as follows: the water conduit guide groove enables the filter water pipe to cooperate with the settling depth in the guide groove during the process of spraying to guide the vertical end of the filter water pipe, and the filter water pipe will be filtered when it is sprayed to the required depth. The gap between the head end of the water pipe and the collecting well is sealed to complete the joint work between the well and the pipe.

The sand-blocking steel box is installed in conjunction with the water collecting well factory, so that the collecting water section does not form an incomplete circular structure due to the filter water guiding channel: the sand blocking steel box and the sand blocking board assembly are used to temporarily close the water filter guide. The opening formed by the trough is to prevent the sand from entering the collecting well when the collecting well sinks, and the sand blocking steel box can be disassembled during the spraying to make the head end of the filtering water pipe settle in the guiding channel of the filtering water pipe and block the sand from entering the set. Inside the well.

As shown in Figures 6H and 6I, the sand board assembly is installed with the head of the water filter pipe before the settling pipe is settling. The ring-shaped filter water retaining sand plate (21b) is installed and the sand-proof plate hanger (21h) is installed. When the filter water pipe is set, the sand-retaining plate (21a) is also matched with the settlement depth. The above is matched with the sand-blocking steel box. When the water filter pipe is set, the sand outside the well does not enter the collecting well. When the whole filter water pipe is completely sprayed, the sand pipe is removed and the filter water pipe is used to guide the steel bar and the concrete is poured to block the sand. After entering the collecting well, the sand blocking plate that is no longer used is hoisted after the whole collecting well has completed the sealing operation of the filter water channel guide groove.

In summary, the double plug nozzle is used for the spray-sinking operation, and the filter water guide channel of the water collecting well is used in conjunction with the sand-shielding steel box and the sand-blocking plate assembly to block the sand. The water pipe sinking operation was successfully completed.

The method of the present invention (including equipment description, working principle and operation mode, etc.)

8A and 8B are respectively described as follows:

The principle of work and work Double sprinkler head a. The structure of the double plug nozzle

The main sinking equipment of this method is a double plug water jet head (1) as shown in Fig. 2, Fig. 3 and Fig. 3A to Fig. 3H, with the sprinkler (11) at both ends being the water spray section (12). And the structure is a water jet head central pipe (13) having a central pipe water passage hole (13b), a water injection section upper opening round steel cylinder (12b), and a lower water injection section round steel cylinder (12f). a water spray section composed of an upper rubber film (12a) of the water spray section; and a pipe plug (11) composed of a pipe plug partition (11i), a pipe plug end 钣 (11k), and a pipe plug rubber film (11a), The pipe plug system fixes the pipe rubber film (11a) with a rubber film fixing 钣 (11b) and a spacer 11 (11d) with a bolt washer and a nut (11c) respectively at the pipe end 钣 (11k) and the pipe plug partition. (11i); and the upper rubber film (12a) of the upper spray section of the water spray section is wrapped around the outer round hole of the water spray section (12b), and is fitted with a spacer washer (11d) with a bolt washer and a nut The rubber film is fixed at both ends of the round steel cylinder, and the round steel cylinder is used to strengthen the strength of the round steel cylinder of the upper and lower openings. As shown in Fig. 3 and Fig. 3C, a front support wheel (12e) is provided on the open circular steel cylinder (12f) at the lower portion of the water spray section after the front end pipe plug, as shown in Fig. 3 and Fig. 3H, The outer side of the end pipe plug has a rear support ring (11f) to fix the rear support wheel (11e), so that the double plug spray head can move back and forth when the water is not pressurized, and the end of the central pipe of the spray head has a water pipe joint stiffening 钣The high pressure water pipe joint (11h) of (11j) is used to connect the high pressure water pipe (11g).

b. Working principle of double plug nozzle

As shown in Fig. 4 and Fig. 4A to Fig. 4C, when the double plug nozzle is placed in the water filter pipe (7) and the high pressure water pipe (11g) is filled with water but not pressurized, the pipe plugs at both ends (11) The outer wall of the rubber membrane of the pipe plug is still not expanded and is still smaller than the inner wall of the water filter pipe. Therefore, the water spray head is supported by the front support wheel (12e) and the rear support wheel (11e). At this time, the front and rear support wheels can easily be used. The sprinkler moves back and forth. As shown in Figure 5 and Figure 5A to Figure 5C, when the water jet head is placed in the water filter pipe and the high-pressure water pipe is connected to the water and pressure, the central pipe high-pressure water (13c1) is connected to the central pipe of the water jet head (13). The water-passing holes (13b) between the pipe plugs at both ends (11i) and the pipe ends (11k) enter the pipe plugs (11), and the high-pressure water (13d) in the formed steel cylinders makes the pipe plugs The rubber film (11a) expands and tightly presses the inner wall of the water filter pipe which is in contact with the rubber film of the pipe plug, so that the water filter hole (73) on the inner wall of the filter water pipe is completely blocked by the rubber film, so that the high pressure water pipe flows into the double plug. All the water flow in the water jet head can only be discharged from the steel cylinder through the water hole (12d) of the water spray section (12) between the pipe plugs at both ends to form the high pressure water (13e) outside the steel cylinder.

After the water pressure in the round steel cylinder continues to rise, the high pressure water (13e) of the steel cylinder flowing out through the water spray hole (12d) of the cylindrical wall of the upper opening of the water spray section enters the round steel cylinder and the water spray section from the upper opening. After the closed space composed of the upper rubber film (12a), the upper rubber film of the water spray section is expanded by the high pressure water to tightly press the inner wall of the water filter pipe which is in contact with the rubber film of the pipe plug, so that the steel pipe water spray hole on the inner wall of the section ( 12d) is completely enclosed by the rubber membrane, and the upper half of the water spray section is formed into a pipe plug so that the water in the upper half of the adjacent water filter pipe section is blocked and cannot be circulated, and only the circular steel cylinder can be opened by the lower part of the water spray section. And the water filter hole (73) on the wall of the filter pipe outside the bottom is sprayed by the high pressure jet (13c), so that the lower side of the filter pipe and the sand layer at the bottom of the pipe form a pipe, and the friction of the side wall and the bottom are lost. The wall supports the force, and the filter tube sinks due to gravity.

If the water jet head is removed from the upper rubber film of the water spray section, the water jet head can be used for segmentation when the water pressure applied to the water jet head is sufficient to form the pipe plugs at both ends without causing the sand pipe in the outer layer of the water filter pipe. Clean the filter water hole blocked by the sand on the wall of the filter water pipe; if the round steel cylinder on the upper part of the spray head is changed to the semi-circular steel cylinder without the open hole, the spray head can be sprayed without installing the upper rubber film of the spray section. The function of the sink water pipe.

c. The operation mode of the double plug nozzle in the water filter pipe

As shown in Figure 1, first place the sprinkler head into the filter water pipe and connect the high-pressure water pipe. Clamp the high-pressure water pipe with the water pipe clamp (84) on the workbench (8), and then push and pull the jack (83) with the water pipe as shown in Figure 5D. Figure (a) pushes the water jet head to the bottom end of the tube; then starts the high pressure water pump (82) and pressurizes to form a pipe plug at both ends of the water jet head, and forms a high pressure jet on the side of the outer water filter pipe and the bottom of the pipe. The water filter pipe of this section is slightly tilted after being sunk by the weight of the spray head, the water filter pipe and the counterweight (74) as shown in Fig. 5D (b) due to loss of side friction and bottom support force; then the high pressure is stopped. The water in the water pipe is pressurized and released, so that the rubber film at both ends of the water spray head and the upper half of the middle water spray section shrinks due to pressure reduction, and the pipe plug effect is lost.

Then push and pull the jack with a water pipe, as shown in Figure 5D (c), pull the water jet head back to the collecting well. After the length of the semi-spray section, the high-pressure water pump is started and pressurized, so that the pipe plug is formed at both ends of the sprinkler head and the high-pressure jet is formed in the middle spray section, and then the filter water pipe is sunk to the same depth as the front water filter pipe section. By measuring the elevation of the depth gauge (75) connected to the water filter pipe to synchronously control the pressure and pressure relief of the high pressure water pipe, the water filter pipe can be sunk to the same depth as the front section; thus repeating the above-mentioned water jet head repeatedly Pull back, pressurize and depressurize the operation and monitor the elevation of the depth mark, as shown in Figure 5D (d) to (f), the integral branch water pipe can be sprayed to the same depth; then to the next depth Repeating the aforementioned spraying operation can successively spray the branch water pipe to the required depth.

2. Collection well a. The structure of the catchment well

The water collecting well of the water collecting device is composed of a bottom portion and a well body section which are placed on site or in the factory, and the planar shape thereof may be a circular shape, an elliptical shape, a square shape, a rectangular shape or a hexagonal shape. Take the in-house reinforced concrete circular collecting well (referred to as the collecting well) as an example. As shown in Figure 6 and Figure 6A to Figure 6K, the circular collecting well (2) is from the bottom of the collecting well. Section (2A) and several collection wells (2B) are formed (referred to as the bottom section and the well section respectively), and the bottom part of the bottom is provided with a blade foot (25) for the sinking of the collecting well. Wedge into the sand layer to facilitate the sinking operation of the collecting well. When all the bottom section and the well section sink to a predetermined depth, the concrete is sealed. The bottom section of the well and the top surface of each well section are provided with lifting rings and anchor ribs (26) for hanging and hanging. When the two collecting well sections are hoisted and joined, the joint surface is joined by quick-setting concrete mortar to prevent The sand outside the well flows into the collecting well.

In addition, a water conduit guide groove (20) is arranged on the well wall of the collecting well for guiding the head end of the water filter pipe to sink to a predetermined depth when the water is sprayed, and the sand blocking steel box (22) is located near the middle of the water guiding pipe guide groove. Temporarily connect the well walls on both sides of the water conduit guide groove, so that each collection well section temporarily becomes a complete structure during hoisting, and prevents the outside sand from flowing into the well when the collecting well sinks; at the near outer wall of the filter water conduit guide groove A sand shield guide groove (21e) with a semi-flexible filler material (21j) with a guide groove is provided for guiding the water filter block sand plate (21b) and the sand shield plate (21a) to be sprayed on the filter water pipe When it is lowered in the guide groove, it is used to cooperate with the sand blocking steel box to block the sand flowing outside the well into the collecting well, and the semi-flexible filler material of the guiding groove is used to protect the water filter guiding channel from being blocked when the collecting well sinks The sand is blocked. As for the steel bars that have been cut due to the opening of the water filter channel guide, the filter water pipe guide groove is used to temporarily connect the steel bars and the protective rubber sleeve (22e) for temporary treatment, so as to facilitate the sinking operation of the water collecting well and the water discharge pipe. After the water filter is sprayed, it is removed and protected. After the rubber sleeve, the cut steel bar is joined by welding or steel splicer, and finally the concrete is poured through the sealing template to complete the sealing work of the water filter guide groove.

b. Working mode of sinking water well sinking

The land preparation is completed at the location where the collection well is scheduled, and then the bottom of the water collection well (2A) is hoisted toward the waterside at the water conduit guide, and then as shown in Figures 7A to 7C. Grab (88) and other mechanical excavation sand in the well to carry out the sinking operation of the bottom section of the collecting well to the near surface of the top surface; then, on the top surface of the bottom section, apply a layer of quick-setting concrete mortar as the upper and lower well sections. After the bonding agent of the surface, and then hoisting the first collecting well (2B), the sinking operation of the collecting well is continued to the near surface of the top surface.

Subsequently, the subsequent joint coating of the well sections, the lifting of the well section, and the sinking of the well section are repeated until the depth of the bottom of the water conduit of the bottom section reaches a predetermined depth, and then closed by concrete (24). At the bottom of the collecting well, the sinking operation of the collecting well is completed.

c. Construction of the water conduit guide groove

As shown in Fig. 6 and Fig. 6A to Fig. 6K, the collecting well faces the waterside from the top of the well to the top of the bottom of the well, and a filtering water conduit (20) is provided to accommodate the water filtering pipe.
