Description

Technical Field

[0001] The invention relates to a fluidized solidified soil production device, and more specifically to an intelligent multifunctional fluidized solidified soil production system. Background Art

[0002] In the process of backfilling foundation trenches of various projects, we often encounter problems such as narrow foundation trench backfill space, large backfill depth, unstable backfill soil compaction quality, and high backfill soil quality requirements. In recent years, there are more and more deep foundation pit support projects. Due to the loose backfill soil, the building's scattered water, pipelines, access roads and other parts have sunk and damaged, and accidents of loss of use function have occurred from time to time. At the same time, the foundation trench backfill is limited by backfill conditions, space and other factors and cannot be backfilled densely. The existence of this situation poses a threat to the seismic performance of tall buildings. Traditional processes mostly use plain soil or gray soil in layers using small compaction equipment for construction. The construction is difficult, the backfill period is long, and the quality of the backfill is difficult to control. Therefore, in order to ensure the quality of the backfill, most projects have to use plain concrete for backfilling. The cost of using plain concrete backfill is high, and the high strength brings difficulties to later repairs and maintenance. Premixed fluidized solidified soil is a new type of building material specially researched and innovated to address the above problems. It makes full use of the excavated or abandoned foundation soil of fertilizer troughs and foundation pits. After adding a certain proportion of curing agent and water, it is fully mixed evenly through original technology and special machinery to form a pumpable and fluid reinforcement material. It is used for backfilling and pouring of various fertilizer troughs, foundation pits, and mine pits. It can also be widely used in reinforcement treatment fields such as roadbeds and building foundations. The slump of premixed fluidized solidified soil after uniform mixing is 8 to 20 cm. The strength of premixed fluidized solidified soil after hardening is 0.5 to 10 MPa. Add admixtures according to soil quality and design requirements during mixing. The premixed fluidized solidified soil can adjust the mix ratio according to the requirements of use to adjust its strength and fluidity.

[0003] Premixed fluidized solidified soil has high strength and fluidity suitable for pumping construction. It not only has fast construction speed, but also has high strength, controllable quality, low cost, wide application range, and environmental friendliness. It is a very good construction material. However, the existing fluidized solidified soil is affected by problems such as uneven particle size of soil raw materials, insufficient degree of agglomerate fragmentation, and large variability in physical properties. During the preparation process, the ratio often needs to be adjusted continuously. In addition, the degree of mechanical integration is not high, resulting in low work efficiency.

[0004] At the same time, the current fluidized solidified soil treatment generally has high requirements for raw materials, and the source of raw materials is single, which cannot meet the requirements of resource utilization of various waste materials generated by various construction projects. At present, the waste materials and various soils generated by various construction projects can be used for reuse of fluidized solidified soil, which mainly includes the following types: slag containing large pieces of gravel, clay with high water content and high viscosity, silty clay, silt, silt sand, medium sand, gravel, and mud generated by various constructions, cement soil mud, and construction waste generated by building demolition, mainly including concrete, broken bricks and mixed steel bars. Faced with a large number of various construction wastes and various soils, how to effectively treat and efficiently prepare fluidized solidified soil is a problem that needs to be solved in this field.

[0005] There are many varieties of curing agents at present, but there is a lack of targeted formulas for curing agents due to the complex raw materials with diverse sources.

[0006] The difficulty in processing and preparing raw materials lies mainly in the fact that the sources of raw materials are diverse and their physical and chemical properties are complex and changeable. A multifunctional and comprehensive processing system is needed.

[0007] Specifically, the types of raw materials and their main problems are as follows:

[0008] (1) Muck containing large pieces of gravel: Conventional treatment is basically not used at present because the treatment cost is too high. Excavators are required to remove large pieces of gravel. The moisture content in the slag is high, and a large number of soil blocks are sticky. Vibration screening cannot separate the slag, resulting in the inability to effectively treat the slag containing large pieces of gravel.

[0009] (2) Various clays excavated from foundation pits or trenches in the south and in various forms. Due to the high groundwater level in the south, various clays excavated from foundation pits are generally silty clays, which are basically in large lumps and cannot be directly used as raw materials for fluidized solidified soil. Conventional treatment is first sun-dried or baked, then crushed by a crusher, and then mixed. The treatment time is long and the cost is high.

[0010] (3) Silt, silt sand, and medium-coarse sand can be directly used as raw materials for fluidized solidified soil. However, silt, silt sand, medium-coarse sand, and clay are often mixed together at construction sites and cannot be used directly as raw materials, making them difficult to handle.

[0011] (4) Pebbles and gravels cannot be used directly as raw materials. Similarly, at construction sites, silt, silt sand, medium-coarse sand and clay are often mixed together and cannot be crushed by conventional crushers. The processing is difficult and costly.

[0012] (5) Various types of mud are often produced during construction, especially at cast-in-place pile construction sites and underground continuous wall construction sites. Various types of mud have different densities, sand contents, and water contents. As the raw materials for fluidized solidified soil, the proportions often need to be changed, resulting in unstable quality control of the fluidized solidified soil.

[0013] (6) Cement soil is easy to harden due to the presence of cement and cannot be stored for a long time, resulting in a setting time problem for cement soil as a fluid solidified soil. Cement soil has high strength and solidifies into large lumps of soil. Conventional mixers cannot effectively mix it, so it is very difficult to effectively utilize cement soil.

[0014] (7) As a fluidized soil solidification device, the current conventional processing equipment can only process conventional raw soil, which is not solidified into large soil blocks.

[0015] (8) As a fluidized soil solidification device, the conventional processing equipment currently processes relatively single objects, such as sludge or plain soil, or dry construction waste (mainly concrete blocks or brick fragments), or mud. There is no comprehensive system that can process multiple raw materials.

[0016] (9) As a fluidized soil solidification device, the current conventional processing equipment loading device uses an excavator or a forklift, which is manually operated by the driver and the mixing ratio is not easy to control.

[0017] (10) The conveyor belt can also be used as a feeding device for general processing of broken soil or small pieces of crushed soil, but it cannot effectively transport various types of soil blocks that have solidified into large pieces.

[0018] (11) There are many types of curing agents currently, but there is a lack of targeted formulas for curing agents due to the complex and diverse sources of raw materials.

[0019] In view of the above problems existing in the traditional fluidized solidified soil production process, it is necessary to develop and design an intelligent multifunctional fluidized solidified soil production system. Summary of the invention

[0020] 1. Technical problem to be solved by the invention

[0021] The purpose of the present invention is to overcome the above-mentioned shortcomings of the existing fluidized solidified soil production, and to provide an intelligent multifunctional fluidized solidified soil production system, which solves the problem that the existing processes or equipment cannot utilize various waste materials generated by various construction projects that are currently increasing to produce fluidized solidified soil. The technical scheme of the present invention is adopted, and an extrusion crusher is used to crush slag soil containing large pieces of gravel into small gravel, and small gravel, various types of sand and soil and other raw materials are sent to the extrusion mixer according to the proportion through the aerial crane grabbing mechanism, and mud is input into the extrusion mixer and vigorously stirred to form a solidified soil slurry, and then the solidified soil slurry is mixed and stirred with a curing agent in a fluidized solidified soil mixing station to form a fluidized solidified soil slurry, forming a set of multifunctional intelligent fluidized solidified soil system capable of processing a variety of raw materials, reducing the processing difficulty and cost of producing fluidized solidified soil raw materials, making the material ratios of the fluidized solidified soil easier to control, improving the stability and production efficiency of the fluidized solidified soil, and allowing various waste materials generated by construction to be reused, thereby achieving the goal of green and low-carbon.

DETAILED DESCRIPTION

[0053] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.

[0054] [Example]

[0055] Combination Figure 1 and Figure 2As shown, an intelligent multifunctional fluidized solidified soil production system of the present embodiment includes an aerial crane grabbing mechanism 1, a slag bin 2, an extrusion crusher 3, a small gravel bin 4, a sand and soil bin 5, an extrusion mixer 6, a mud treatment pool 7, a solidified soil slurry pool 9, a curing agent tank 10, a fluidized solidified soil mixing station 11 and a central control system. The slag bin 2, the extrusion crusher 3, the small gravel bin 4, the sand and soil bin 5 and the extrusion mixer 6 are respectively arranged below the aerial crane grabbing mechanism 1, and the aerial crane grabbing mechanism 1 grabs the raw materials in the slag bin 2 into the extrusion crusher 3 or grabs the raw materials in the small gravel bin 4 and the sand and soil bin 5 into The small gravel bin 4 is connected with the discharge port 3-4 of the extrusion crusher 3, and the raw materials in the slag bin 2 are crushed by the extrusion crusher 3 to form small gravel raw materials and enter the small gravel bin 4; the slag bin 2 is used to store slag containing large pieces of gravel, and the small gravel bin 4 is used to store slag containing gravel with smaller particle size and small gravel slag formed by the extrusion crusher 3; the sand and soil bin 5 is used to store silt sand, medium coarse sand and various clays, cement soil, etc. By classifying and storing different raw materials, and being able to use the aerial crane grabbing mechanism 1 according to different raw materials, it is beneficial to the stability of the fluidized solidified soil components and proportions. The mud treatment pool 7 and the solidified soil slurry pool 9 are arranged on one side of the extrusion mixer 6. The mud treatment pool 7 is used to store and process various types of mud. The solidified soil slurry pool 9 is used to store the mixed solidified soil slurry. The mud formed in the mud treatment pool 7 is transported to the extrusion mixer 6 through a mud pump. The extrusion mixer 6 is used to vigorously stir the raw materials in the corresponding silo and / or the mud in the mud treatment pool 7 to form solidified soil slurry and pump it into the solidified soil slurry pool 9. The solidified soil slurry pool 9 and the curing agent tank 10 are respectively connected to the fluidized solidified soil mixing station 11 through a conveying mechanism. The fluidized solidified soil mixing station 11 mixes and stirs the solidified soil slurry and the curing agent to form a fluidized solidified soil slurry. The central control system controls and adjusts the ratio of the raw materials in the extrusion mixer 6, the amount of mud input into the extrusion mixer 6, and the ratio of the solidified soil slurry and the curing agent input into the fluidized solidified soil mixing station 11 according to the type of raw materials in the corresponding silo. By adopting the intelligent multifunctional fluidized solidified soil production system, the slag containing large pieces of gravel is crushed into small gravel by means of the extrusion crusher 3, and the small gravel, various types of sand and soil and other raw materials are sent into the extrusion mixer 6 according to the proportion through the aerial crane grabbing mechanism 1, and the mud is input into the extrusion mixer 6 and vigorously stirred to form solidified soil slurry, and then the solidified soil slurry and the curing agent are mixed and stirred in the fluidized solidified soil mixing station 11 to form a fluidized solidified soil slurry in a flowing state, forming a multifunctional intelligent fluidized solidified soil system capable of processing a variety of raw materials, reducing the processing difficulty and cost of making fluidized solidified soil raw materials, making the proportion of each material constituting the fluidized solidified soil easier to control, improving the stability and production efficiency of the fluidized solidified soil, and making various waste materials generated by construction to be reused, achieving the goal of green and low-carbon.

[0056] Reference Figure 1 and Figure 2 As shown, in this embodiment, the sand and soil silo 5 includes a cement soil silo 51. The cement soil raw materials in the cement soil silo 51 are grabbed by the crane grabbing mechanism 1 and put into the extrusion mixer 6 for strong stirring to form a primary solidified slurry. The central control system adjusts the amount of the later curing agent according to the cement content of the cement soil raw materials; the cement content of the cement soil raw materials is obtained by analyzing the image sensor and the specific gravity sensor. Due to the presence of cement, cement soil is easy to harden and cannot be stored for a long time. By concentrating the cement soil in the cement soil silo 51, and then using the crane grabbing mechanism 1 to grab the cement soil into the extrusion mixer 6 for strong stirring, the primary solidified slurry is formed to participate in the production of fluidized solidified soil. In this way, the reuse of waste cement soil is realized, the use of later curing agent can be effectively reduced, and the production cost can be reduced. The cement content in different cement soils is different. The cement content can be obtained by intelligent computer analysis through an image sensor combined with a specific gravity sensor, and the amount of cement soil and later curing agent can be adjusted by the central control system according to the cement content. In addition, the extrusion mixer 6 can further mix and crush the cement soil that has solidified into large lumps of soil, thereby reducing the difficulty of utilizing the cement soil.

[0057] The above-mentioned sand and soil silo 5 also includes a clay silo 52, a silt silo 53, a silty clay silo 54 and a sand silo 55. The sand silo 55 can be divided into a medium-coarse sand silo and a silt silo. The aerial crane grabbing mechanism 1 grabs various raw materials produced at the construction site transported by the transport vehicle 12 and distributes them to the corresponding silos. The aerial crane grabbing mechanism 1 can more accurately, reliably and conveniently control the proportion accuracy of various raw materials such as clay, silt, silt sand, medium-coarse sand, etc., reduce the uncontrollability caused by human operation, and help ensure the stability of fluidized solidified soil. Specifically, the current imaging recognition system can be used to automatically identify the types of raw materials loaded in the truck arriving at the raw material silo, and the AI ​​system automatically sends instructions to the aerial crane grabbing mechanism 1, which directly distributes the raw materials to each silo. The device is also used to distribute the raw materials of each silo to the extrusion mixer 6.

[0058] like Figure 1 and Figure 2As shown, in this embodiment, the above-mentioned mud treatment pool 7 includes a mud pool 71, a mud sedimentation pool 72 and a mud storage pool 73. The mud pool 71 is used to store waste mud from the construction site. The source of the mud is mainly a large amount of mud of different densities generated by the construction of cast-in-place pile sites, underground continuous wall sites, etc. The sand content and water content of these muds are different. If they are directly used as raw materials to make fluidized solidified soil, it is necessary to frequently change the proportion to ensure the quality stability of the fluidized solidified soil. The mud sedimentation pool 72 is used to precipitate the mud to filter out excess water, and the mud storage pool 73 is used to store the mud with a low water content formed by the mud sedimentation pool 72; in this embodiment, the mud is precipitated by the mud sedimentation pool 72, which reduces the water content of the mud and makes the mud in a relatively stable state, so there is no need to frequently change the proportion of the fluidized solidified soil. The mud in the mud storage tank 73 is transported to the extrusion mixer 6 through a mud pump. The size of the mud delivery amount is transmitted by the specific gravity sensor of the mud storage tank 73 to the central control system, and the central control system adjusts the amount of mud according to the type of primary raw materials. In addition, the present embodiment also has a clean water tank 8, and clean water is stored in the clean water tank 8. When the humidity of the primary raw materials is too dry, an appropriate amount of clean water can be injected into the extrusion mixer 6 or the fluidized solidified soil mixing station 11 through a water pump. The intelligent multifunctional fluidized solidified soil production system of the present embodiment can be set up in a site, which is surrounded by a site wall 14, and 1 to 2 entrances and exits can be left as needed to facilitate production management.

[0059] Reference Figure 1 , Figure 2 and Figure 7 As shown, the curing agent tank 10 and the fluidized solidified soil mixing station 11 are the same as the prior art. The solidified soil slurry in the solidified soil slurry pool 9 is pumped to the fluidized solidified soil mixing station 11. The curing agent in the curing agent tank 10 is transported to the fluidized solidified soil mixing station 11 through an auger conveying device. The solidified soil slurry and the curing agent are fully mixed in the fluidized solidified soil mixing station 11.

[0066] In order to further understand the technical content of the present invention, now combined with Figure 1 and Figure 2 The implementation process of an intelligent multifunctional fluidized solidified soil production system of the present invention is further described:

[0067] S1, the transport vehicle 12 transports various raw materials generated at the construction site to the corresponding silo; the mud transport vehicle transports the waste mud from the construction site to the mud treatment pool 7 for preliminary treatment;

[0068] S2, the crane grabbing mechanism 1 distributes various raw materials to corresponding silos, such as the slag silo 2, the small gravel silo 4, the clay silo 52, the silt silo 53, the silty clay silo 54, and the sand silo 55);

[0069] S3, the raw materials in the slag bin are grabbed by the overhead crane grabbing mechanism 1 and sent to the strong extrusion crusher 3 for extrusion crushing to form small gravel raw materials, which then enter the small gravel bin 4;

[0070] S4, the crane grabbing mechanism 1 intelligently grabs the raw materials from each silo according to the proportion of the central control system to the powerful extrusion mixer 6 for powerful mixing to form a fluidized solidified soil slurry, which is then pumped to the solidified soil slurry pool 9;

[0071] S5, mud processing process: first, the mud is sent to the mud sedimentation tank 72 to filter out excess water, forming mud with low water content, and then entering the mud storage tank 73; then the mud is transported to the extrusion mixer 6 by a mud pump, and the size of the transport amount is transmitted by the specific gravity sensor of the mud storage tank 73 to the central control system, and the central control system adjusts the amount of mud according to the type of primary raw materials;

[0072] S6, cement soil processing process: The cement soil is transported to the cement soil bin 51 by a transport vehicle, and then grabbed into the extrusion mixer 6 by the crane grabbing mechanism 1 for strong mixing to form a primary solidified slurry, and the amount of the later curing agent is adjusted according to the different cement content of the cement soil; the different cement content is also analyzed by an intelligent computer using an image sensor combined with a specific gravity sensor;

[0073] S7, the solidified soil slurry pool is pumped to the fluidized solidified soil mixing station 11, and the solidifying agent tank 10 also transports the solidifying agent to the fluidized solidified soil mixing station 11 through the auger conveying device. The central control system intelligently adjusts the ratio of the solidified soil slurry and the solidifying agent according to the solidifying agent formula, and the fluidized solidified soil mixing station 11 stirs the fluidized solidified soil slurry to form a flowing state, which is transported to various construction sites by the fluidized solidified soil transport vehicle (i.e., the mixer truck 13) to backfill the fertilizer tank and the ditch.

[0074] The intelligent multifunctional fluidized solidified soil production system of the present invention is a multifunctional intelligent fluidized solidified soil system equipment capable of processing a variety of raw materials. The system is composed of a variety of silos (slag silos, small gravel silos, clay silos, silty clay silos, silty soil silos, sand silos, etc.), mud slurry pools, mud sedimentation pools, mud storage pools, high-power extrusion multi-stage crushers, high-power extrusion mixers, solidified soil slurry pools, overhead crane grabbing mechanisms, curing agent tanks and fluidized solidified soil mixing stations, as well as a supporting central control room and specific gravity sensors and image sensors for each silo and mud pool.

[0075] Specifically, the present invention solves the following technical problems:

[0076] (1) The squeeze crusher solves the problem of the inability to effectively process the slag containing large pieces of gravel;

[0077] (2) The extrusion mixer solves the problem of long processing time and high cost of various clays in foundation pits or trenches and various forms of excavation in the south;

[0078] (3) The extrusion mixer solves the problem that silt, silt sand, medium-coarse sand and clay are mixed together at the construction site and cannot be directly used as raw materials, making them difficult to handle;

[0079] (4) The extrusion crusher solves the problem that gravel cannot be used directly as raw material. At the same time, silt, silt sand, medium-coarse sand and clay are often mixed together at the construction site, which cannot be crushed by conventional crushers, resulting in great difficulty and high cost.

[0080] (5) The mud with different sand content and water content is pre-treated in the mud treatment pool, which solves the problem that the quality control of the fluidized solidified soil is unstable due to the frequent change of the proportion of muds of different densities as raw materials;

[0081] (6) The use of an extrusion mixer solves the problem that cement soil is easy to harden due to the presence of cement and cannot be stored for a long time, and conventional mixers cannot effectively mix it, thereby solving the problem that there are great difficulties in the effective use of cement soil;

[0082] (7) The extrusion mixer can extrude, cut and mix the soil that has not solidified into large pieces, solving the problem that conventional processing equipment can only process conventional raw soil;

[0083] (8) The use of an overhead crane grabbing mechanism in conjunction with a central control system and corresponding sensors solves the problem that the conventional processing equipment's loading device uses an excavator or a forklift, which is manually operated by the driver and the ratio is difficult to control; it also solves the problem that the conveyor belt, as a loading device, cannot effectively transport various types of soil blocks that have solidified into large pieces.

[0084] In short, the present invention solves the problem that existing processes or equipment cannot make fluidized solidified soil using various waste materials generated by various construction projects. An extrusion crusher is used to crush slag soil containing large pieces of gravel into small gravel, and small gravel, various types of sand and soil and other raw materials are sent to the extrusion mixer according to the proportion through the aerial crane grabbing mechanism, and mud is input into the extrusion mixer and vigorously stirred to form solidified soil slurry, and then the solidified soil slurry is mixed and stirred with the curing agent in the fluidized solidified soil mixing station to form a fluidized solidified soil slurry, forming a multifunctional and intelligent fluidized solidified soil system that can handle a variety of raw materials, reducing the difficulty and cost of processing raw materials for making fluidized solidified soil, making the proportion of each material that makes up the fluidized solidified soil easier to control, improving the stability and production efficiency of the fluidized solidified soil, and allowing various waste materials generated by construction to be reused, achieving the goal of green and low carbon.
