Description

Technical Field

[0001] The invention relates to the technical field of grouting equipment, and in particular to a grouting equipment for tunnel construction with a wastewater recovery mechanism. Background Art

[0002] When tunnel construction grouting equipment is working, a large amount of wastewater will be generated. If this wastewater is discharged directly without recycling, it will not only pollute the ecological environment around the construction site but also cause waste of water resources. Therefore, it is necessary to configure a wastewater recycling mechanism on the grouting equipment to deal with the above problems.

[0003] Most of the existing grouting equipment's sedimentation boxes lack a structure for temporarily blocking and sealing the dirt settled out at its bottom, the outlet of the sewage inlet pipe thereon, and the inlet of the recovery pumping pipe thereon; the lack of a blocking and sealing structure for the precipitated dirt will result in the precipitated dirt not being temporarily blocked and limited when the clean water in the sedimentation box is recovered and pumped for utilization, and it is easy to be pumped into the recovery water pump through the recovery pumping pipe in large quantities, causing excessive wear on the impeller of the water pump; the lack of a blocking and sealing structure for the sewage inlet and outlet will result in the outlet of the sewage inlet pipe being blocked when the clean water in the sedimentation box is recovered and pumped for utilization If the water inlet cannot be temporarily blocked, sewage will continue to be discharged into the sedimentation tank through the sewage inlet pipe, causing a large amount of waste that has not been treated in time to be directly pumped into the recovery water pump through the recovery pump pipe, causing excessive wear on the impeller of the water pump; the lack of a blocking and blocking structure at the water inlet of the recovery pump pipe will result in the water inlet of the recovery pump pipe not being able to be temporarily closed when the sewage is normally settled and filtered using the sedimentation tank, causing a large amount of waste precipitated during the sedimentation process to directly enter the recovery pump pipe through the water inlet of the recovery pump pipe, which may cause the recovery pump pipe to be blocked.

[0004] Although some existing grouting equipment is equipped with the above three blocking and blocking structures in the settling box thereon, the three blocking and blocking structures need to be opened or closed step by step before and after the clean water is recovered and sucked for utilization, which makes the operation and use more troublesome and inconvenient. Summary of the invention

[0005] In view of this, the present invention provides a grouting equipment for tunnel construction with a wastewater recovery mechanism to solve the problem that the three blocking and blocking structures need to be opened or closed step by step before and after the clean water is recovered and sucked for utilization, which makes the operation and use more troublesome and inconvenient.

[0010] Furthermore, the wastewater receiving cover is a rectangular cone-shaped structure, and a first-level sedimentation tank is welded and hoisted on the drain outlet at the center of the bottom thereof, the first-level sedimentation tank and the second-level sedimentation tank are arranged adjacent to each other, the tail end of the sewage conduit is fixedly connected to the side wall of the corresponding side of the first-level sedimentation tank, and a U-shaped connecting pipe is welded on the bottom of the first-level sedimentation tank and the second-level sedimentation tank, and a sewage pipe with a valve is welded on the middle section of the U-shaped connecting pipe; The portion of the vertical driving shaft located above the upper threaded section is a bare rod structure, the bare rod portion is rotatably matched with the wastewater receiving cover, and a plum blossom-shaped knob is welded on the top of the vertical driving shaft.

[0011] Furthermore, the chassis is a rectangular frame structure, and two groups of L-shaped support rods, one long and one short, are welded at intervals at the top ends of the two long side rods. The pulping drum and the mixing drum are respectively welded and fixed between the top ends of the two groups of long L-shaped support rods and between the top ends of the two groups of short L-shaped support rods. The wastewater receiving cover is welded and fixed between the vertical rod sections of the four groups of L-shaped support rods. Each set of L-shaped support rods is composed of two L-shaped support rods arranged at intervals, and a row of pedals is welded between the two vertical rod sections of each set of long L-shaped support rods; The pulping cylinder and the mixing cylinder are both provided with a rotating mixing assembly.

The dirt can be temporarily blocked in the bottom space of the secondary sedimentation tank, so as to avoid the lack of blocking and limiting of the dirt when the secondary clean water in the upper space of the secondary sedimentation tank is sucked and recovered through the recovery suction pipe, and the dirt is easily sucked into the water injection pump in large quantities through the recovery suction pipe, causing excessive wear on the impeller of the water injection pump.

[0015] 2. When the rectangular cover plate is driven to come into contact with the water outlet of the sewage conduit, the water outlet can be closed. The water outlet can be closed to prevent the primary clean water still containing dirt in the primary clean water from continuously overflowing into the secondary clean water through the sewage conduit during the process of sucking and recovering the secondary clean water in the upper space of the secondary clean water. This will cause a large amount of dirt in the primary clean water that has not yet been filtered out to be mixed into the secondary clean water and directly sucked into the water injection pump, causing excessive wear on the impeller of the water injection pump.

[0016] 3. When the circular cover is driven to come into contact with the water inlet of the recovery suction pipe, the water inlet can be closed to prevent impurities in the primary clean water that continuously overflows into the secondary sedimentation tank from directly entering the recovery suction pipe during long-term normal secondary filtration of sewage, which may block the recovery suction pipe.

[0017] 4. In the present invention, a row of longitudinal baffles, rectangular cover plates, and the opening and closing operations of the rectangular cover plates can be performed simultaneously at one time by simply rotating the vertical drive shaft forward and backward, which greatly simplifies the operating steps of the above three cover plate components and effectively improves the convenience and practicality of the operation and use of the three cover plate components.

[0030] Preferably, an electric control box 10 is fixed at a corner of the chassis 1, and contactors for controlling the start and stop of the rotary stirring assembly 4, the water injection pump 5 and the grouting pump 7 are arranged inside the electric control box 10; two fixed wheels and two universal wheels are symmetrically arranged at the bottom of the chassis 1, and the two fixed wheels and the two universal wheels are arranged at a long distance.

[0031] Preferably, two vertical positioning shafts 906 are symmetrically welded on the inner side of a long side wall of the secondary sedimentation box 9, and slip rings are welded on the outer sides of the upper halves of the two vertical force transmission rods 904, and the two slip rings correspond to and slide with the two vertical positioning shafts 906.

[0032] The working principle, specific details, implementation steps, functions and interrelationships of the above-mentioned features, and their roles in implementing the present invention are described in detail below: The L-shaped water suction pipe 502 is connected to an external water source through a hose. When in use, cement and various additives are poured into the slurry barrel 2, and the water injection pump 5 is started to pump clean water into the slurry barrel 2, and then the rotary stirring assembly 4 on the slurry barrel 2 is turned on to stir the cement, various additives and water at high speed to make cement slurry, and then the L-shaped slurry discharge pipe 201 is opened to discharge the cement slurry into the mixing barrel 3, and the rotary stirring assembly 4 on the mixing barrel 3 is turned on to stir the cement slurry at a low speed to prevent the cement slurry from coagulating, and then the ... The grouting pump 7 sucks and pressurizes the cement slurry in the mixing drum 3 through the grouting pipe 703, and sprays the cement slurry on the construction positions that need grouting repair during the tunnel construction process through the grouting hose 701 and the spray gun 702 in turn. During use, the grouting equipment can be pushed and transferred by two directional wheels and two universal wheels, and the dirt accumulated in the bottom space of the two-stage sedimentation tank (i.e., the first-stage sedimentation tank 6 and the second-stage sedimentation tank 9) needs to be discharged regularly through the U-shaped connecting pipe 11 and the sewage pipe 1101.

[0033] The wastewater receiving cover 8 is used to receive the wastewater mixed with cement and various additives that overflows from the pulping drum 2 and the mixing drum 3. After being received in the wastewater receiving cover 8, the wastewater first flows down into the primary sedimentation tank 6 for primary sedimentation and filtration. In this process, the dirt in the wastewater is settled and temporarily stored in the bottom space of the primary sedimentation tank 6. The filtered primary clean water is discharged into the secondary sedimentation tank 9 through the sewage conduit 601. After the primary clean water enters the secondary sedimentation tank 9, it is subjected to secondary sedimentation and filtration. The filtered dirt is settled and temporarily stored in the bottom space of the secondary sedimentation tank 9, and the filtered secondary clean water floats and is stored in the upper space of the secondary sedimentation tank 9. When the secondary clean water inside the secondary sedimentation tank 9 is full, the water injection pump 5 and the valve on the recovery suction pipe 901 are opened, and the secondary clean water is sucked and injected into the pulping drum 2 by the water injection pump 5 for recycling.

[0034] When the secondary clean water inside the secondary sedimentation tank 9 is recovered and sucked for utilization, a row of longitudinal baffles 940 is driven to a swing-up horizontal state, and the rectangular cover plate 903 and the circular cover plate 920 are slidably driven to a state where they are respectively abutted and closed against the water outlet of the sewage conduit 601 and separated from the water inlet of the recovery suction pipe 901; when a row of longitudinal baffles 940 is swing-driven to a horizontal state, its two long sides are successively abutted and docked and together form a complete large-area covering plate, which temporarily closes the bottom space of the secondary sedimentation tank 9 and blocks the dirt in the bottom space, and can temporarily block the dirt in the bottom space of the secondary sedimentation tank 9, to avoid the lack of blocking and limiting of the dirt when the secondary clean water in the upper space of the secondary sedimentation tank 9 is sucked and recovered through the recovery suction pipe 901, and it is easy for the dirt to be sucked out in large quantities through the recovery suction pipe 901 The water is sucked into the water injection pump 5, causing excessive wear on the impeller of the water injection pump 5; when the rectangular cover plate 903 is driven to come into contact with the water outlet of the sewage conduit 601, the water outlet can be closed. The closing of the water outlet can prevent the primary clean water containing dirt in the primary settling tank 6 from continuously overflowing into the secondary settling tank 9 through the sewage conduit 601 during the process of sucking and recovering the secondary clean water in the upper space of the secondary settling tank 9, causing a large amount of dirt in the primary clean water that has not yet been filtered out to be mixed with the secondary clean water and directly sucked into the water injection pump 5, causing excessive wear on the impeller of the water injection pump 5; when the circular cover plate 920 is driven to separate from the water inlet of the recovery suction pipe 901, the water inlet can be opened. After the water inlet is opened, the recovery suction pipe 901 can be used to recover and suck the secondary clean water inside the secondary settling tank 9.

[0035] After the recovery and suction operation of the secondary purified water is completed, when the sewage is subjected to long-term normal secondary filtration through the secondary sedimentation tank 9, the row of longitudinal baffles 940 needs to be driven to a state of lowering and erecting, and the rectangular cover plate 903 and the circular cover plate 920 need to be slidably driven to a state where they are separated from the outlet of the sewage conduit 601 and abut against and close to the water inlet of the recovery suction pipe 901 respectively; when the row of longitudinal baffles 940 is driven to an erect state by lowering, the cover plate can be decomposed and the bottom space of the secondary sedimentation tank 9 can be opened, so that the impurities in the primary purified water overflowing into the secondary sedimentation tank 9 can be continuously discharged. Normally, the sewage is deposited in the bottom space; when the rectangular cover plate 903 is driven to separate from the outlet of the sewage conduit 601, the outlet can be opened to allow the primary sewage to continue to overflow into the secondary sedimentation tank 9 through the sewage conduit 601; when the circular cover plate 920 is driven to abut against the water inlet of the recovery suction pipe 901, the water inlet can be closed to prevent the impurities in the primary clean water that continuously overflows into the secondary sedimentation tank 9 from directly entering the recovery suction pipe 901 during the long-term normal secondary filtration of the sewage, which may block the recovery suction pipe 901.

[0036] The vertical support slide plate 910, the second connecting rod 909 and the upper threaded ring 9021 are connected together to form a crank slider mechanism, through which the upper threaded ring 9021 can slide up and down to drive the vertical support slide plate 910 and the circular cover plate 920 to slide back and forth along the longitudinal positioning shaft 930, so as to switch the water inlet of the recovery suction pipe 901; the T-shaped transmission rod 908, the second connecting rod 909, the vertical slide plate 907 and the lower threaded ring 9021 are connected together to form a crank slider mechanism, through which the lower threaded ring 9021 can slide up and down to drive the T-shaped transmission rod 908 and The vertical slide plate 907 slides back and forth along the longitudinal positioning shaft 930 to switch the outlet of the sewage conduit 601; the horizontal drive rod 905, a row of first connecting rods 9051 and a row of longitudinal baffles 940 are connected together to form a complete set of crank rocker mechanisms. Through the complete set of crank rocker mechanisms, the horizontal drive rod 905 that slides up and down can drive the row of longitudinal baffles 940 to swing up and down synchronously to open and close; the vertical drive shaft 902 can rotate forward and reverse through the two sections of external threads thereon to drive the two threaded rings 9021 to slide up and down synchronously, controlling the rectangular cover plate 903, the T-shaped transmission rod 908 and the rectangular cover plate 903 to move in the same direction and the same direction. The two vertical positioning shafts 930 slide back and forth in the form of steps to open and close the water outlet of the sewage conduit 601 and the water inlet of the recovery suction pipe 901, and close and open them respectively, which can save the trouble of opening and closing the water outlet of the sewage conduit 601 and the water inlet of the recovery suction pipe 901 in steps before and after the recovery and suction of the secondary purified water; the T-shaped transmission rod 908, the two vertical force transmission rods 904 and the two pull rods 9081 are connected together to form two sets of crank slider mechanisms, through which the T-shaped transmission rod 908 is driven back and forth along the two vertical positioning shafts 930 When sliding, it can also drive the horizontal driving rod 905 to slide up and down, and control a row of longitudinal baffles 940 to swing up and down synchronously to open and close, which can save the trouble of opening and closing a row of longitudinal baffles 940 before and after the secondary purified water is recovered and sucked for utilization; in this way, the opening and closing operations of a row of longitudinal baffles 940, the rectangular cover plate 903 and the rectangular cover plate 903 in the present invention can be performed synchronously at one time with only a simple operation of rotating the vertical driving shaft 902 forward and reverse, which greatly simplifies the operation and use steps of the above three cover plate components, and effectively improves the convenience and practicality of the operation and use of the three cover plate components.

[0037] It is worth noting that the dirt deposited in the bottom space of the secondary sedimentation tank 9 should be discharged and cleaned in time to prevent the dirt from gradually accumulating and overflowing a row of longitudinal baffles 940, thereby blocking and hindering the normal swinging and opening and closing of a row of longitudinal baffles 940.
