Description

Technical Field

[0001] The invention relates to a vacuum preloading device of a combined container and a vacuum preloading method thereof. Background Art

[0002] The 21st century is an era of great development, and various projects are being carried out in full swing. In recent years, the speed of social development has been getting faster and faster, the basic living standards of the people have been getting higher and higher, infrastructure construction has entered a period of great development, and the amount of various projects has also increased. Mud is an indispensable medium for bored piles, underground continuous walls, and shield tunneling operations. It has the functions of suspending soil residue and preventing hole wall collapse. However, with the increase of foundation engineering, bridge engineering, municipal engineering, etc., a large amount of waste mud is generated during the construction process. Due to the scattered and disordered sources of engineering waste mud, mud storage occupies precious construction sites and leads to a poor on-site construction environment. The existing means of treating mud are expensive. Mud treatment has always been a problem that plagues engineering construction. In addition, the treatment of engineering waste mud has received increasing attention from the construction department and the environmental protection department. Finding a high-efficiency, low-energy consumption, and environmentally friendly waste mud treatment method has become urgent. Vacuum preloading method, as an effective method for reinforcing and treating dredged silt, has gradually been applied in engineering. Horizontal drainage board vacuum preloading technology reduces the amount of mud to achieve the purpose of reducing the cost of engineering waste mud treatment. However, this method has high requirements for construction conditions and a long overall processing time, which is difficult to achieve the progress of the construction site. Therefore, it is necessary to further improve its processing efficiency. Taking advantage of the standardization of containers and combining the vacuum preloading method of horizontal drainage boards, the construction flexibility can be improved to a certain extent. However, the processing efficiency of a single container is low and the processing volume is limited. Therefore, it is proposed to combine multiple containers and use their own weight to further improve the treatment effect, so as to maximize the treatment efficiency of engineering waste mud. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a vacuum preloading device for a modular container. The device and its use method combine multiple containers, and use the deadweight of the container filled with mud to further promote the drainage and consolidation of the mud, thereby greatly improving the reinforcement effect of the mud and greatly shortening the processing time. During the process of reinforcing the mud, the lifting function of the device can also be used to continue to inject mud, thereby achieving a capacity expansion effect. The device significantly improves the efficiency of treating engineering waste mud in combination with the vacuum preloading method of the container, and can continuously treat it in a limited space.

[0004] To achieve the above object, the present invention provides the following technical solution: A vacuum preloading device for a combined container, including a bottom plate and supporting members disposed above the bottom plate. The supporting members are perpendicular to the bottom plate and extend reversely towards one side of the bottom plate. Multiple lifting platforms are provided on the supporting members. An extrusion panel is provided at the bottom of the lifting platform. The extrusion panel and the lifting platform enclose a receiving cavity for receiving an external container. A vacuum preloading system member is provided inside the container. A plurality of load-bearing members are provided inside the lifting platform. The load-bearing members are used to support the container. The load-bearing members are lifted by hydraulic jacks. When the mud inside the container drops by 50 cm, the upper container can be lifted to perform secondary mud pouring.

[0005] Further, both the bottom plate and the load-bearing members are made of hard thickened steel.

[0006] Further, the load-bearing members are 50 cm long. The lifting platform is composed of 4 load-bearing members each 50 cm long. The load-bearing members are fixed to the side of the supporting members. The load-bearing members are lifted along the length direction of the supporting members. The supporting members are formed by steel pipes 4 meters long.

[0007] Further, the vacuum preloading system member includes horizontal drainage plates, drainage pipes, and vacuum pumping equipment. The horizontal drainage plates are evenly distributed inside the container. The drainage pipes are connected to the horizontal drainage plates and the vacuum pumping equipment. After the treatment of the waste mud is completed, the container panel is disassembled, and the waste mud can be removed outside the three-dimensional rack along with the horizontal drainage plates.

[0008] Further, it includes the following steps:

[0009] Step 1: Fix the lifting platform and place the container on the load-bearing members of each layer of the lifting platform;

[0010] Step 2: First mud pouring: Lift each layer of the container. After pouring 0.5 meters of mud, lay a layer of horizontal drainage plates on the mud surface and connect the drainage systems of each layer;

[0011] Step 3: In the order of the mud from bottom to top, fill each layer of the container with mud in sequence. Then, press the extrusion panel at the bottom of the upper container onto the lower container and turn on the vacuum pumping equipment for reinforcement treatment;

[0012] Step 4: As the mud drains and settles, slowly press the extrusion panel into the interior of the lower container;

[0013] Step 5: When the extrusion panel is completely pressed into the container, lift the upper container to perform the second mud pouring until the container is full;

[0014] Step 6: Press the extrusion panel at the bottom of the upper container onto the lower container again and continue with drainage reinforcement.

[0015] Step 7: After the reinforcement is completed, raise the upper container, remove the side panels of the container, and take out the horizontal drainage board together with the lumped slurry.

[0016] Advantages of the present invention:

[0017] 1. The present invention uses a container as the treatment box. On the one hand, it can eliminate the site limitation of the traditional vacuum preloading method, with convenient operation, improved construction speed, and cost savings for the production of slurry pits. On the other hand, it fully utilizes the standardized specifications of the container, and the prefabricated horizontal drainage board system can be mass-produced in the factory in advance. Only component assembly is required on-site to treat the slurry, which simplifies the construction process to the greatest extent and greatly improves the treatment efficiency.

[0018] 2. In the present invention, multiple containers are combined, and by using the extrusion panel under the load-bearing member in the container lifting platform, the self-weight of the upper container filled with slurry can be cleverly applied to the lower slurry, realizing further reinforcement treatment of the slurry.

[0019] 3. The present invention uses a container lifting platform device, making the process of container slurry treatment more flexible and convenient. The combined containers use their own weight for surcharge loading, which can greatly accelerate the slurry treatment speed and save the construction period.

[0020] 4. In the present invention, a container with detachable side panels is used. By setting a sealing ring at the panel connection and combining with the extrusion panel under the upper load-bearing member, the tightness during the entire vacuum preloading process can be well ensured, thus guaranteeing the effect of slurry treatment. Moreover, after the slurry treatment is completed, the side panels of the container can be removed, facilitating the transportation and cleaning of the slurry.

[0021] 5. The frame of the prefabricated horizontal drainage component in the present invention is made of lightweight synthetic plastic, and geotextiles are laid on both the upper and lower sides of the drainage board to filter the slurry, so that the horizontal drainage component can still be recycled after the slurry treatment, achieving the effect of environmental protection and conservation.

A plurality of load-bearing members 31 are disposed in the lifting platform 3. The load-bearing members 31 are used for supporting the container 5. The load-bearing members 31 are lifted by hydraulic jacks. After the slurry in the container 5 drops by 50 cm, the upper container 5 can be lifted to perform secondary slurry filling.

[0030] The above improvement is specifically as follows: As Figure 1As shown in the figure, the vacuum preloading device includes a bottom plate 1 and supporting members 2 arranged above the bottom plate 1. A lifting platform 3 is arranged on the side of the supporting members 2, and the lifting platform 3 can extend along the length direction of the supporting members 2. A container 5 is placed on one lifting platform 3, and a vacuum preloading system component 6 is externally connected to the container 5. Through the setting of the vacuum preloading system component 6, the container 5 can be effectively accommodated. Through the setting of the load-bearing members 31, the container 5 can be effectively supported. When evacuating the slurry, first, the lifting platform 3 needs to be fixed on the ground, and then each layer of load-bearing members 31 is installed on the supporting members 2. Four load-bearing members 31 and an extrusion panel 4 enclose to form a lifting platform 3. Then, the container 5 is installed on the lifting platform 3, and the vacuum preloading system component 6 is connected to the outside of the container 5 for evacuation (the vacuum preloading system component 6 is a prior art, and the specific operation method of the evacuation technology will not be elaborated further). After installing multiple containers 5 according to the above method, a hydraulic jack is arranged above the container 5. Through the setting of the hydraulic jack, the lifting of the load-bearing members 31 can be effectively achieved. When the slurry in each container 5 compresses and drops by 50 cm, the container 5 can be opened, and the slurry can be poured in again. In this way, it is superior to the prior art, can effectively combine multiple containers 5, and further improve the treatment effect by using the self-weight effect.

The load-bearing member 31 is fixed on the side of the supporting member 2, and the load-bearing member 31 moves up and down along the length direction of the supporting member 2. The supporting member 2 is formed by a steel pipe 4 meters long.

[0033] The above improvement is specifically: the extrusion panel 4 is connected by four steel pipes each 50 cm long under each layer of load-bearing members 31, which not only increases the stability of the lifting platform 3 but also plays a role in transmitting the self-weight load of the upper container 5, so that the slurry in the lower container 5 is further drained and consolidated.

[0034] On the basis of the above embodiment, as Figure 4 Figure 5 As shown in the figure; the vacuum preloading system component 6 includes a horizontal drainage board 61, a pumping pipeline 62, and a vacuum pumping device 63. The horizontal drainage boards 61 are evenly distributed in the container 5. The pumping pipeline 62 is connected to the horizontal drainage board 61, and the vacuum pumping device 63. When the treatment of the waste slurry is completed, the panel of the container 5 is disassembled, and the waste slurry can be removed out of the three-dimensional rack along with the horizontal drainage board 61.

[0035] The above improvements are specifically as follows: The horizontal drainage plates 61 are arranged in layers in the container 5, and the vacuum pumping device 63 is connected to the horizontal drainage plates 61. The connection manner between the vacuum pumping device 63 and the horizontal drainage plates 61 is the prior art, so no more description will be given here.
