Description

Technical Field

[0001] This utility model relates to a slurry storage tank and a water-based construction device for producing mud-stabilized soil. Background Technology

[0002] Slurry-stabilized soil is a new type of underwater backfill material for scour pits. Its slurry exhibits good fluidity in its early stages. When pumped into scour pits around bridge pile foundations, the slurry spontaneously fills and compacts the gaps between the scour pit and the pile-soil mixture. Currently, the production of slurry-stabilized soil involves first digging a large pit on land to form a slurry preparation tank, then using an excavator to mix soil, water, and solidifying agent in the tank. This process causes environmental pollution and has low slurry preparation efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a slurry storage tank and water construction equipment for making mud-stabilized soil.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A slurry storage tank for producing slurry-stabilized soil includes a shell and a stirring device. The shell has a receiving cavity with an opening at the top. The stirring device includes a moving trolley and a stirring head. The stirring head is connected to the moving trolley and can drive the stirring head to move within the receiving cavity. The stirring head can rotate under the drive of a driving mechanism.

[0006] In this solution, the slurry storage tank for producing slurry-stabilized soil includes a shell and a mixing device. The mixing head of the mixing device moves within the housing cavity of the shell under the drive of a mobile trolley. During the movement, the mixing head rotates, thereby mixing the slurry-stabilized soil in the housing cavity, ensuring that the soil, water, and solidifying agent are mixed evenly, thus improving slurry preparation efficiency. Furthermore, the shell can be used for both slurry preparation and storage of slurry-stabilized soil, eliminating the need to dig pits on land and reducing environmental pollution. In addition, the shell can be transported to the construction site for slurry preparation, reducing the distance for transporting slurry-stabilized soil, shortening construction time, and improving construction efficiency.

[0007] Preferably, the shell is a box, and the box is provided with lifting lugs to facilitate the overall hoisting of the slurry storage tank.

[0008] Preferably, the stirring device further includes guide rails, two of which are installed parallel to each other on the housing and located above the opening of the housing. The two guide rails extend along the length and / or width of the slurry storage tank. The rollers of the moving trolley cooperate with the guide rails and can move along the guide rails. The stirring head is suspended below the moving trolley.

[0009] In this design, the trolley moves along the guide rail, which in turn moves the mixing head, increasing the mixing area of ​​the mud and improving the mixing effect. The guide rail is installed above the opening, positioning the trolley above and away from the mud. Only the mixing head below the trolley moves within the receiving cavity to mix the mud, preventing the trolley from moving within the mud and thus protecting it.

[0010] Of course, in an alternative solution, the mobile trolley can move either outside or inside the container.

[0011] Preferably, the guide rails include transverse guide rails and longitudinal guide rails, and the moving trolley includes a longitudinal trolley and a transverse trolley. The two longitudinal guide rails are installed on opposite sides of the housing along the length of the housing, and the two longitudinal trolleys are respectively installed at both ends of the two transverse guide rails. The two transverse guide rails are movably mounted on the two longitudinal guide rails via the longitudinal trolleys, and the transverse trolleys are movably mounted on the two transverse guide rails. The stirring head is suspended below the transverse trolleys.

[0012] In this design, the transverse trolley can drive the stirring head to move along the transverse guide rail, while the longitudinal trolley can drive the transverse guide rail, the transverse trolley, and the stirring head to move longitudinally. This allows the stirring head to cover any area of ​​the cavity, preventing dead zones and improving the stirring effect.

[0013] Preferably, the slurry storage tank further includes a support member located in the middle of the receiving cavity, the lower end of the support member being connected to the inner wall of the shell, and two stirring devices being provided, the two stirring devices jointly covering the area where the receiving cavity is located, with the longitudinal guide rail of each stirring device being connected to the upper end of the support member.

[0014] In this design, two mixing devices can operate simultaneously, improving mixing efficiency. A support structure is installed in the middle of the receiving cavity to support the longitudinal guide rails, reducing the span of the longitudinal guide rails to allow for a larger volume slurry storage tank.

[0015] Preferably, there are multiple support members, which are spaced apart along the extension direction of the longitudinal guide rail.

[0016] In this solution, the above-mentioned structural design is adopted to improve the support effect of the longitudinal guide rail and prevent the longitudinal guide rail from bending and deforming due to excessive span.

[0017] Preferably, the stirring head has a box-type frame structure.

[0018] In this design, the box-frame structure mixing head has a larger mixing area and higher mixing efficiency compared to the spiral mixing head. It also has higher strength and is less susceptible to damage from hard mud lumps in the slurry.

[0019] Preferably, the stirring device further includes a remote control, which is communicatively connected to the mobile trolley and used to control the start and stop of the mobile trolley and / or the drive mechanism.

[0020] In this solution, the above-mentioned structural configuration facilitates remote control of the movement and mixing operation of the mixing device, reduces manual intervention, and improves work efficiency.

[0021] A type of waterborne construction equipment, comprising a flat barge and a slurry storage tank for producing slurry-stabilized soil as described above, wherein the shell of the slurry storage tank is disposed on the platform of the flat barge.

[0022] In this scheme, the slurry storage tank is set on a flat barge, which can be positioned near the construction site of the pile foundation. This allows for the on-site preparation of slurry-stabilized soil on the water near the pile foundation, shortening the transportation distance of the slurry-stabilized soil and preventing it from solidifying. At the same time, the slurry storage tank can store a large amount of slurry-stabilized soil, which also facilitates the pumping of a large amount of slurry-stabilized soil to the scour pit under the pile foundation at one time, thereby reducing the loss rate of slurry-stabilized soil and significantly reducing construction costs.

[0023] Preferably, the flat barge is unpowered and small in size compared to large construction vessels, so it does not affect the normal operation of the waterway.

[0024] Preferably, the water-based construction equipment further includes a delivery pump and a pipeline, with the delivery pump installed on the pipeline. One end of the pipeline is connected to the receiving cavity of the slurry storage tank, and the other end of the pipeline is equipped with a pump head.

[0025] In this design, the pump head is used to sink into the scour pit under the pile foundation, and the delivery pump is used to pump the slurry-stabilized soil from the storage tank to the scour pit. The delivery pump and pipeline are mounted on the casing, facilitating rapid pumping operations and eliminating the need for additional pipelines and delivery pumps, thus improving construction efficiency.

[0026] Preferably, the water-based construction equipment also includes a transport vehicle and a pump truck, the transport vehicle being used to transport mud, and the pump truck being used to pump the mud to the storage tank.

[0027] In this scheme, the above-mentioned structural setup facilitates the division of the mud-stabilized soil production method into two steps. The first step is to produce mud on land, and the second step is to store the mud in a storage tank and add a solidifying agent to stir it, thus producing mud-stabilized soil slurry. Compared with producing mud-stabilized soil in one go using construction equipment on water, this can greatly improve construction efficiency.

[0028] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0029] The positive and progressive effects of this utility model are as follows: The slurry storage tank for making slurry-stabilized soil includes a shell and a stirring device. The stirring head of the stirring device moves within the housing cavity of the shell under the drive of a mobile trolley. During the movement, the stirring head rotates, thereby stirring the slurry-stabilized soil in the housing cavity, making the soil, water and solidifying agent evenly mixed, and improving the slurry making efficiency. Furthermore, the shell can be used for both slurry making and slurry-stabilized soil storage, eliminating the need to dig pits on land and reducing environmental pollution. In addition, the shell can be transported to the construction site for slurry making, reducing the distance for transporting slurry-stabilized soil, shortening construction time and improving construction efficiency.

[0052] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0053] like Figure 1 and Figure 2 As shown, this embodiment discloses a slurry storage tank for producing slurry-stabilized soil. The slurry storage tank 10 includes a shell 1 and a stirring device 2. The shell 1 has a receiving cavity 11 with an opening at the top. The stirring device 2 includes a moving trolley 21 and a stirring head 22. The stirring head 22 is connected to the moving trolley 21. The moving trolley 21 can drive the stirring head 22 to move within the receiving cavity 11. The stirring head 22 can rotate under the drive of the driving mechanism. The slurry storage tank for making slurry-stabilized soil includes a shell 1 and a mixing device 2. The mixing head 22 of the mixing device 2 moves within the receiving cavity 11 of the shell 1 under the drive of the moving trolley 21. The mixing head 22 rotates during the movement, thereby mixing the slurry-stabilized soil in the receiving cavity 11, making the soil, water and solidifying agent evenly mixed, and improving the slurry making efficiency. In addition, the shell 1 can be used for both slurry making and slurry-stabilized soil storage, so there is no need to dig pits on land, reducing environmental pollution. Furthermore, the shell 1 can be transported to the construction site for slurry making, reducing the distance for transporting slurry-stabilized soil, shortening construction time and improving construction efficiency.

[0054] Preferably, the shell 1 is a box, and the box is provided with lifting lugs to facilitate the overall hoisting of the slurry storage tank 10.

[0055] like Figure 1 and Figure 2 As shown, the mixing device 2 also includes guide rails 23. Two guide rails 23 are installed parallel to each other on the housing 1 and located above the opening of the housing 1. The two guide rails 23 extend along the length and / or width of the slurry storage tank 10. The rollers of the moving trolley 21 cooperate with the guide rails 23 and can move along the guide rails 23. The mixing head 22 is suspended below the moving trolley 21. The moving trolley 21 moves on the guide rails 23, thereby driving the mixing head 22 to move, increasing the mixing area of ​​the slurry and improving the mixing effect. By installing the guide rails 23 above the opening, the moving trolley 21 is positioned above the slurry and away from it. Only the mixing head 22 below the moving trolley 21 moves and mixes the slurry within the receiving cavity 11, preventing the moving trolley 21 from moving in the slurry and protecting the moving trolley 21.

[0056] Of course, in an optional embodiment, the mobile trolley can move outside or inside the housing. The mobile trolley can move on guide rails to improve the smoothness of its movement; however, the mobile trolley can also move in places without guide rails.

[0057] like Figure 1 and Figure 2 As shown, in this embodiment, the guide rail 23 includes a transverse guide rail 231 and a longitudinal guide rail 232, and the moving trolley 21 includes a longitudinal trolley 211 and a transverse trolley 212. The two longitudinal guide rails 232 are installed on opposite sides of the housing 1 along the length direction of the housing 1, and the two longitudinal trolleys 211 are respectively installed at both ends of the two transverse guide rails 231. The two transverse guide rails 231 are movably mounted on the two longitudinal guide rails 232 via the longitudinal trolleys 211, and the transverse trolleys 212 are movably mounted on the two transverse guide rails 231. The stirring head 22 is suspended below the transverse trolleys 212. The transverse trolleys 212 can drive the stirring head 22 to move along the transverse guide rails 231. At the same time, the longitudinal trolleys 211 can drive the transverse guide rails 231, the transverse trolleys 212, and the stirring head 22 to move longitudinally, realizing the coverage of any area of ​​the receiving cavity 11 by the stirring head 22, preventing dead corners, and improving the stirring effect.

[0058] In this embodiment, the slurry storage tank 10 also includes a support member 3, which is located in the middle of the receiving cavity 11. The lower end of the support member 3 is connected to the inner wall of the shell 1. There are two stirring devices 2, which together cover the area of ​​the receiving cavity 11. The longitudinal guide rail 232 of each stirring device 2 is connected to the upper end of the support member 3. The two stirring devices 2 can perform stirring operations simultaneously, improving stirring efficiency. The support member 3 is set in the middle of the receiving cavity 11 to support the longitudinal guide rail 232, reducing the span of the longitudinal guide rail 232, so as to set a larger volume slurry storage tank 10.

[0059] In this embodiment, there are multiple support members 3, which are spaced apart along the extension direction of the longitudinal guide rail 232 to improve the support effect of the longitudinal guide rail 232 and prevent the longitudinal guide rail 232 from bending and deforming due to excessive span.

[0060] In this embodiment, the stirring head 22 has a box-type frame structure. Compared with the spiral-shaped stirring head 22, the box-type frame structure stirring head 22 has a larger stirring area, higher stirring efficiency, and higher strength, making it less susceptible to damage from hard mud lumps in the slurry.

[0061] Of course, in other embodiments, the stirring head may also be a propeller structure.

[0062] Preferably, the mixing device 2 also includes a remote control, which is communicatively connected to the mobile trolley 21 and used to control the start and stop of the mobile trolley 21 and / or the drive mechanism, so as to facilitate remote control of the movement and mixing operation of the mixing device 2, reduce manual intervention, and improve work efficiency.

[0063] like Figure 3As shown, this embodiment also discloses a waterborne construction device, which includes a flat barge 20 and a slurry storage tank 10 for producing slurry-stabilized soil as described above. The shell 1 of the slurry storage tank 10 is disposed on the platform of the flat barge 20. During construction operations, the flat barge 20 can be positioned at the construction site close to the pile foundation 100 to facilitate the production of slurry-stabilized soil on-site near the pile foundation 100, shortening the transportation distance of the slurry-stabilized soil and preventing the slurry-stabilized soil from solidifying. At the same time, the slurry storage tank 10 can store a large amount of slurry-stabilized soil, which also facilitates the one-time pumping of a large amount of slurry-stabilized soil to the scour pit 200 under the pile foundation 100, thereby reducing the loss rate of the slurry-stabilized soil and significantly reducing construction costs.

[0064] Preferably, the flat barge 20 is unpowered and small in size compared to large construction vessels, so it does not affect the normal operation of the waterway.

[0065] Preferably, the underwater construction equipment also includes a delivery pump 30 and a pipeline 40. The delivery pump 30 is installed on the pipeline 40, one end of which is connected to the receiving cavity 11 of the slurry storage tank 10, and the other end of the pipeline 40 is equipped with a pump head. The pump head is used to sink into the scouring pit 200 under the pile foundation 100, and the delivery pump 30 is used to pump the slurry solidified soil in the slurry storage tank 10 to the scouring pit 200. The delivery pump 30 and pipeline 40 are configured on the housing 1, facilitating rapid pumping operations and eliminating the need for additional pipeline 40 and delivery pump 30, thus improving construction efficiency.

[0066] In this embodiment, the slurry storage tank 10 has a movable stirring device 2, which facilitates thorough and uniform mixing after adding the solidifying agent to the slurry. The size of the slurry storage tank 10 is determined comprehensively based on the dimensions of the flat barge 20 (construction positioning vessel), the power of the delivery pump, and the tidal conditions of the water area, in order to pump as much slurry-stabilized soil as possible and reduce the underwater loss rate of the slurry-stabilized soil. Preferably, the pumping of the fluidized solidified soil is carried out during the slack tide period to further reduce the underwater loss rate of the slurry-stabilized soil. In one embodiment, based on the duration of the slack tide period and the power of the delivery pump 30, the pumping time for each pumping can be estimated, thereby calculating the pumping volume for each pumping to be approximately 200 cubic meters. This is while considering the standard 3-meter module of the tank, and ensuring that the slurry storage tank 10 is placed at a height that is not too high on the flat barge 20. Preferably, the dimensions of the slurry storage tank 10 are set to be 21 meters long, 6 meters wide, and 2 meters high, with a maximum capacity of 252 cubic meters. Considering that the slurry cannot be fully loaded during mixing, the liquid level is about 1.6 meters when the total amount of slurry in the slurry storage tank 10 reaches 200 cubic meters, so as to meet the mixing requirements.

[0067] Preferably, the water-based construction equipment also includes a transport vehicle and a pump truck 50. The transport vehicle is used to transport the mud, and the pump truck 50 is used to pump the mud to the storage tank 10. The configuration of the transport vehicle and pump truck 50 on the water-based construction equipment facilitates dividing the mud-stabilized soil preparation method into two steps: mud preparation and solidifier addition. The large-scale mud preparation is carried out on land, while the smaller-scale solidifier addition is carried out on the water platform. Compared to preparing the mud-stabilized soil all at once using the water-based construction equipment, this reduces the difficulty of water-based operations, facilitates the preparation of mud-stabilized soil close to the construction site, shortens the transportation time of the mud-stabilized soil, and improves construction efficiency.

[0068] This method involves transporting pre-prepared mud on land without adding a hardener. A large quantity of mud is collected in a storage tank 10 on the ship, and then the hardener is added uniformly. This solves the problem of the hardened soil slurry losing its fluidity due to prolonged transportation after adding the hardener, thus ensuring the workable time of the hardened soil slurry. Furthermore, this method is less demanding on the transportation time of the mud trucks; as long as mud reserves are prepared before pumping the hardened soil, it is sufficient. If transporting slurry with added hardener, there are strict requirements on the convoy's transportation distance and time, which must not exceed the initial setting time of the hardened soil to prevent loss of fluidity during prolonged transportation, which could lead to pipe blockage during subsequent pumping.

[0069] Furthermore, a slurry storage tank 10 is installed on the flat barge 20 to store a certain volume of slurry. After the slurry is added with a solidifying agent and mixed evenly, a large amount of solidified soil slurry is pumped into the flushing pit 200 at once to achieve a certain "initial injection volume" and greatly reduce the underwater loss rate. If the prepared slurry solidified soil is transported by transport vehicle and then directly pumped into the flushing pit 200 under the pile foundation 100, the maximum volume per vehicle is only about 30 cubic meters, which makes the pumping volume too small each time, resulting in a high underwater loss rate.
