The applicant finds that in the use of the existing pressure relief structure of the basement anti-floating plate and the construction method (CN 103147464B): in the prior art, a mode of pumping underground water out by using a water guide pipe for pressure relief is adopted, so that the pressure on a basement bottom plate can be reduced, the cracking of the basement bottom plate is avoided, and after long-term use, a sandy gravel reverse filter layer or other filter layers are easy to block; when the silting problem appears in the filter layer, generally adopt the means of artifical mechanical desilting, nevertheless because the filter layer sets up below concrete layer usually and the aqueduct is the fixed state, generally can't carry out the desilting or the great problem of the desilting degree of difficulty to the filter layer.
Disclosure of Invention
The invention aims to provide a basement flow guiding and pressure limiting structure which can clean a filtering layer and avoid the problem of silting.
The invention is realized by the following technical scheme: a basement flow guiding and pressure limiting structure comprises a bearing layer and a water guide pipe, wherein a jack is drilled on the basement floor, and the water guide pipe can be inserted into the bearing layer of a basement bottom plate from the jack and pulled out; the bottom end of the aqueduct is a water inlet end, a filtering component is arranged in the aqueduct, and a steel mesh is arranged at an opening of the water inlet end of the aqueduct. This scheme is the improvement of making on current basement pressure release structure, current pressure release structure can have higher filtering action and discharge groundwater from the drainage tube to rising groundwater in the initial stage use, can play better pressure release effect, nevertheless after using longer time, accumulate easily in the filter layer in the structure when groundwater flows each type of impurity that carries, most impurity in groundwater can be intercepted by the filter layer, play the filtering action to the groundwater of come-up, nevertheless when impurity accumulates too much in the filter layer, silt phenomenon appears easily in the filter layer, groundwater can't permeate from the filter layer even, lead to groundwater come-up pressure too big, lift the phenomenon of basement bottom plate or the local fracture of basement bottom plate. Therefore, the applicant provides a basement flow guiding and pressure limiting structure aiming at the found problems, the silting phenomenon of a filter layer can be thoroughly solved, and the problem that the basement bottom plate cracks or is lifted is avoided. The specific implementation mode is as follows:
the basement bottom plate is drilled with the insertion holes, the water guide pipe can be inserted into the bearing layer of the basement bottom plate from the insertion holes, and the bottom end opening of the water guide pipe is provided with the steel mesh, so that the problem that large particles enter the water guide pipe to form blockage can be avoided; the filtering component is placed in the water guide pipe, the steel plate can also prevent the filtering component from falling out of the bottom of the water guide pipe, the side edge of the filtering component can be matched with the inner wall of the water guide pipe, and the filtering component can filter the underground water entering the water guide pipe; in the scheme, in the long-term use process, substances carried in underground water are partially attached to the filtering component, and after the filtering capacity of the filtering component is reduced, the water guide pipe can be directly pulled out due to the detachable connection between the water guide pipe and the jack, and the filtering component is taken out of the water guide pipe and replaced; when the filter assembly is replaced, the water guide pipe can be inserted into the jack of the basement bottom plate again.
Therefore, this scheme is through changing the filter layer among the prior art into mobile detachable structure, can guarantee to change at any time promptly, when filter assembly's filtering quality descends, can change new filter assembly to guarantee that basement water conservancy diversion voltage limiting structure has better filter effect all the time, wash the filter bed, avoid silting up the problem. The applicant also finds that another implementation mode can be adopted in the practical use process of the scheme, namely in the process of inserting the water guide pipe into the basement bottom plate, the side wall of the filtering assembly is in a contact matching state with the inner wall of the water guide pipe, so that the underground water can be discharged out of the water guide pipe only after being filtered by the filtering assembly, the matching between the filtering assembly and the water guide pipe is tight, if the filtering assembly is directly placed into the water guide pipe, the filtering assembly cannot naturally descend to the bottom end of the water guide pipe, a rod piece is usually required to push the filtering assembly to the bottom of the water guide pipe, and when the filtering assembly is taken out, the filtering assembly is troublesome, therefore, the top of the filtering assembly is connected with the rod piece, and the rod piece can be completely placed into the water guide pipe; when the filter assembly needs to be taken out, the rod piece can be pulled outwards, and then the filter assembly can be pulled out; in addition, the applicant finds that if the filter assemblies are pulled out and replaced, the operation is complex, and at least two filter assemblies need to be alternately used, so that the cost is relatively high; the applicant has therefore found that: the general filtering component can be cleaned by water after being disassembled, the filtering component can be used for the second time after most of silted impurities in the filtering component are removed, and when the filtering component is used, the filtering component is in a standing state in a water guide pipe, and the impurities can only be accumulated in the filtering component and cannot be automatically cleaned; however, in the prior art, a technical means of backwashing the filter layer by recharging surface water exists, but various complex devices such as a water pump and a controller are required to be adopted during backwashing, and the device is used in a basement flow guide pressure limiting structure with obvious size and material, so that the scheme needs to adopt a simple structure and an operation mode to realize the cleaning of the filter assembly. Specifically, because the top of filtering component is connected with the member, the member can regard as the power pole of drive filtering component motion, the member can rely on people or mechanical drive, can use the overdrive the member makes filtering component be elevating movement, rotary motion and other irregular motions etc. in the aqueduct, and the groundwater in the usable aqueduct washs filtering component. The cleaned filter assembly can be pushed to the bottom of the water guide pipe through the towing rod to be used continuously. Therefore, the rod piece can play a role in pushing the filter assembly to the bottom of the water guide pipe, a role in pulling the filter assembly out and a role in cleaning the filter assembly as a driving rod of the filter assembly; the structure of the scheme is simple, the problem to be solved can be well solved, the structure is non-obvious, and the rod piece has an unexpected technical effect.
The applicant finds in the course of practical use: the mode of directly pulling out the aqueduct and pouring out the filter assembly is labor-consuming, the filter assembly is inconvenient to take out, and in the process of pulling out and inserting the aqueduct, the inner wall of the jack and the outer part of the aqueduct generate friction, so that the aqueduct is possibly damaged, and the aqueduct is easy to break; the applicant can directly pull out the filter assembly through the rod piece after connecting the rod piece on the filter assembly, but the outer side of the filter assembly and the inner side of the water guide pipe are also scraped in the pulling-out process, and if the water guide pipe is too long, the difficulty in pulling out the filter assembly is high, and the operation is difficult; and the rod piece moves up and down to clean the filter assembly, so that the filter assembly has larger damage to the inner wall of the water guide pipe. Therefore, the applicant has made further improvements: the water guide pipe is arranged to include: the sliding inner pipe is arranged inside the water guide outer pipe, and the water guide inner pipe can be pulled and inserted along the length direction of the water guide outer pipe; the filtering component is arranged inside the sliding inner tube, and the steel mesh covers the bottom end opening of the sliding inner tube. It should be noted that the strength of the sliding inner tube is high, the filtering assembly and the sliding inner tube can be fixedly connected, and in the process of cleaning the filtering assembly, the filtering assembly fixed on the sliding inner tube can be cleaned by using the underground water in the water guide outer tube only by pulling and inserting the sliding inner tube; the technical personnel in the field should know that if there is a gap between the inner wall of the water guide outer pipe and the outer wall of the sliding outer pipe, the damage of the sliding outer pipe to the water guide outer pipe is very small and almost negligible in the process of plugging and unplugging, and if the outer wall of the sliding inner pipe is in contact fit with the inner wall of the water guide outer pipe, the damage to the water guide outer pipe is still very small when the sliding inner pipe is plugged and unplugged because the contact mode is surface contact and is smooth; the problem of change filter assembly or wash easy when filter assembly cause the damage to the aqueduct in the scheme of the last scheme, perhaps operate complicacy can be solved.
Specifically, the steel mesh is arranged at the bottom opening of the water guide outer pipe. The problem that large particles enter between the inner wall of the water guide outer pipe and the outer wall of the sliding inner pipe to influence the pulling and inserting of the sliding inner pipe can be avoided, and the problem that the large particles damage the sliding outer pipe when the sliding inner pipe is pulled and inserted is further avoided; the water guide outer pipe is of a splicing structure connected through a tee joint plug, the position of the tee joint plug is higher than that of the basement bottom plate, the tee joint plug is not selectively opened and closed with a channel connected with the water guide outer pipe, and the water guide outer pipe is detachably connected with the tee joint plug. The three-way plug can be used as an emergency switch, can meet the requirement of pressure relief when underground water rapidly rises, and when a channel which is not connected with the water guide outer pipe and the three-way plug is opened, the rapidly rising underground water can be discharged from the channel. In the practical implementation process, the three-way plug is connected to the position near the middle part of the water guide outer pipe, namely, the water guide outer pipe is divided into an upper part and a lower part; when the top end of the sliding inner pipe is higher than the three-way plug, a sealing ring for preventing underground water from flowing out from the space between the inner wall of the top end of the three-way plug and the outer wall of the sliding inner pipe is arranged in the top end of the three-way plug; when the filtering assembly is cleaned, the upper water guide outer pipe needs to be detached from the top end of the three-way plug, and the sealing ring is arranged to prevent underground water from flowing out from a gap between the sliding inner pipe and the water guide outer pipe; when the height of the sliding inner pipe is lower than the top end of the three-way plug, a sealing ring for blocking the groundwater from flowing out from the position between the inner wall of the water guide outer pipe and the outer wall of the sliding inner pipe is arranged inside the joint of the water guide outer pipe and the three-way plug, when the filtering assembly is cleaned, the lower water guide outer pipe and the bottom of the three-way plug need to be detached, and the sealing ring also plays a role in preventing the groundwater from flowing out from the upper part of the lower water guide outer pipe without being filtered by the filtering assembly; in addition, the height of the sliding inner tube is not limited as long as the sliding inner tube can be easily inserted and removed.
A plurality of exhaust holes are formed in the top end of the water guide outer pipe, and a sealing plate covers an opening in the end portion of the water guide outer pipe. The sealing plate is arranged to prevent foreign objects from falling into the water guide outer pipe and prevent underground water from flowing out of an opening at the top of the water guide outer pipe, if the exhaust hole is not formed, the sealing plate is arranged at the top of the water guide outer pipe to prevent the foreign objects from entering the guide pipe, and the exhaust hole is formed at the top of the water guide outer pipe to balance air pressure, prevent siphonage and facilitate drainage; and one end of the water guide outer pipe, which is positioned above the three-way plug, is connected with a drain pipe, and the water outlet end of the drain pipe is aligned with a drainage ditch or a water collecting well. And a water level observation point is arranged on the pipe wall of the water guide outer pipe and is lower than the connecting position of the drain pipe and the water guide outer pipe, so that the drainage condition can be observed conveniently. When the water guide outer pipes are multiple, the water discharge pipes of two adjacent water guide outer pipes can be connected and communicated, the inlet ends of the water discharge pipes are higher than the outlet ends of the water discharge pipes, namely the inlet ends to the outlet ends of the water discharge pipes are obliquely arranged from top to bottom so as to accelerate the discharge of underground water.
Furthermore, the filtering component comprises a bag body, filtering fillers and a fixing piece, the top of the filtering component is fixedly connected with the sliding inner pipe through the fixing piece, the filtering fillers are filled in the bag body, and the bottom of the bag body is positioned below the sliding inner pipe. The top of the bag body is connected with a rod piece, the top end of the rod piece is rotatably connected with a buoyancy block, the buoyancy block can be waist-shaped or rectangular, the side surface of the buoyancy block is close to the inner wall of the pipe and is not contacted with the inner wall of the pipe, and underground water can flow to the upper part of the buoyancy block from the lower part of the buoyancy block. A limiting block is arranged inside the water guide outer pipe and is higher than the buoyancy block; under the natural state, the limiting block and the buoyancy block are separated. It should be noted that a part of the bag body is positioned inside the sliding inner tube, and a part of the bag body extends out from the bottom of the sliding inner tube, so that the situation that the underground water is required to be discharged and must pass through the sliding inner tube, and the underground water enters the sliding inner tube and must be filtered by the filtering filler in the bag body can be ensured; the fixing piece only fixes the top end of the bag body, so that the flexibility of the shape of the bag body can be ensured, and the bag body can be made of elastic rubber with strong wear resistance; the utility model discloses a water guide outer pipe, including slip inner tube, filtration filler, sealing washer, the slip inner tube can adopt the plastics material that has anticorrosive property of comparatively light, can adopt the haydite of comparatively light in the filtration filler, perhaps adopt the mode that haydite and cobble mix, the surface cover of slip inner tube is equipped with the sealing washer, the sealing washer sets up the upper and lower both ends at the slip inner tube to avoid groundwater to pass through from the clearance of slip inner tube and water guide outer tube. The practical use process is as follows: when the groundwater that infiltrates in the slip inner tube is less, because filter assembly and slip inner tube self have the action of gravity to there is the frictional force effect in the sealing washer on the slip inner tube and the inner wall of direction outer tube, consequently. The underground water can enter the inside of the sliding inner pipe after being filtered by the filtering filler arranged in the bag body from the bag body in the filtering component, the buoyancy of the underground water is enhanced after the underground water in the guide outer pipe is increased, the buoyancy of the underground water is larger than the self weight of the filtering component and the sliding inner pipe and overcomes the friction force of the sealing ring, the sliding inner pipe can float upwards under the buoyancy action of the underground water, and a buoyancy block is connected to the top of the bag body through a rod piece for increasing the buoyancy action of the underground water on the sliding inner pipe; when groundwater contacts the buoyancy piece, groundwater can make the buoyancy piece come-up, the buoyancy piece drives the bag body and together comes up with the gliding inner tube, when the one end of slider top surface and the tip contact of stopper, because the buoyancy piece is connected for rotating with the member, the buoyancy piece rotates, groundwater reduces suddenly to the buoyancy of buoyancy piece, the self gravity of filter assembly and slip inner tube this moment is greater than the frictional force of sealing washer and the buoyancy of groundwater, the slip inner tube descends this moment, get back to the bottom of direction outer tube once more, most groundwater is located the top of buoyancy piece this moment, the buoyancy piece is applyed again, the drain pipe setting of water guide outer tube is in the position that is a little higher than the stopper this moment, in-process when the slip inner tube descends, intraductal groundwater can be pushed out the drain pipe.
Moreover, because the bag body is a flexible and deformable bag body, when the bag body is contacted with the steel mesh at the bottom of the water guide outer pipe, the bag body is in a squeezed state, the outer side of the bag body is in a joint state with the inner wall of the guide outer pipe, so that underground water can completely enter the sliding inner pipe, when the sliding inner pipe is separated from the steel mesh under the action of buoyancy, the bag body can naturally deform, the length of the bag body becomes longer and the outer diameter becomes smaller, the filtering filler filled in the bag body can randomly move in the bag body, and after the outer diameter of the bag body becomes smaller, the distance between the bag body and the sliding inner tube becomes larger, and the bag body can make irregular movement in the process of ascending or descending of the sliding inner tube, when the sliding inner pipe descends to a certain depth, the bag body and the steel mesh are in contact again to generate light collision, and the impurities in the bag body are cleaned and separated out more easily due to the vibration generated by the collision; therefore, the bag body can be backwashed by using the water in the water guide outer pipe, so that impurities can be prevented from being accumulated in the bag body to a certain extent to influence the filtering effect of the filtering component, and the service life of the filtering component is prolonged; the scheme can be used in a water-rich area, when groundwater rapidly rises, the lifting period of the sliding inner tube is shorter, the lifting speed is higher, the lifting times of the sliding inner tube in the same time period are more, and when the lifting speed is higher, the action of filtering fillers in the bag body is larger, and the cleaning effect of groundwater on the bag body is better; it should be noted that most of the impurities washed out from the bag body will generally accumulate at the bottom end of the sliding inner tube, rather than being discharged from the water outlet, and therefore the effect of filtering the groundwater by the bag body is less affected. According to the scheme, the inner sliding pipe can ascend under the buoyancy action of underground water by installing the buoyancy block, the buoyancy block is turned over by the limiting block, and the inner sliding pipe can descend after the buoyancy of the underground water is released; the filter filler in the bag body can irregularly move under the natural state in the ascending and descending processes, and is continuously washed by underground water, when the sliding inner pipe descends to the bottom, the bag body collides with the steel mesh at the bottom of the water guide outer pipe, and the vibration generated by collision can separate part of impurities in the bag body from the filter filler.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. according to the scheme, the jack is arranged in the basement bottom plate, the water guide pipe is inserted into the jack and can be pulled out, and the filter assembly is arranged in the water guide pipe; or the filtering component is cleaned in a mode of continuously plugging the water guide pipe, so that the problem of silting of the existing filtering layer can be avoided.
2. This scheme is through the mode that sets up the member, the member can play and promote the effect to the aqueduct bottom with filter assembly, plays the effect of pulling out filter assembly and as filter assembly's actuating lever to realize the abluent effect of filter assembly.
3. This scheme can be through setting up the gliding mode of slip inner tube in the water guide outer tube, and will filtering component fixes in the outside of slip inner tube, only needs to pull out to insert the slip inner tube promptly, just can realize the washing to filtering component to can reduce the damage to the water guide outer tube to a great extent in the cleaning process.
