Description

Technical Field

[0001] This utility model relates to the field of mud silo structure technology, and in particular to an environmentally friendly and land-saving mud silo structure and its construction method. Background Technology

[0002] Mud is a common byproduct of construction in building and municipal engineering projects. It is typically disposed of in two ways: first, by temporarily storing it in mud silos, allowing it to settle naturally before secondary disposal; second, by transporting it away in real-time using tank trucks. The former requires temporary land acquisition, creating mud silos through digging pits or building dams. This method demands large areas of open land, damages existing surface resources during construction, has a long natural settling time, low turnover efficiency, and is difficult to relocate. The latter method, due to the high water content in the mud, results in large volumes, high transportation costs, and tank trucks have high requirements for transportation conditions, making it generally unsuitable for scenarios with large mud volumes, such as river dredging and flushing.

[0003] In recent years, with increasingly stringent land use conditions and ever-increasing environmental protection requirements, some mud dewatering and drying equipment has been developed and applied in construction and municipal engineering projects with high environmental requirements. However, the deployment of these devices requires space and consumes a lot of energy, resulting in high mud treatment costs and limited economic viability. Therefore, there is an urgent need to conduct research on environmentally friendly and economical mud treatment methods applicable to multiple construction scenarios.

[0004] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an environmentally friendly and land-saving mud storage structure that addresses the shortcomings of existing technologies and is suitable for construction mud treatment scenarios with limited land, complex environments, and poor transportation conditions.

[0006] The technical problem to be solved by this utility model can be achieved by the following technical solution:

[0007] An environmentally friendly and land-saving mud storage structure includes:

[0008] The mud silo enclosure is formed by filling mud pipe bags and enclosing the silo according to the site terrain.

[0009] An impermeable geomembrane is laid at the bottom and around the mud silo enclosure;

[0010] Several rows of water collection wells are arranged longitudinally at intervals within the mud silo enclosure and above the impermeable geomembrane. Each row of water collection wells consists of several water collection wells arranged laterally at intervals.

[0011] A plurality of longitudinal drainage pipe sheets and a plurality of transverse drainage pipe sheets are provided. Two adjacent transversely arranged water collection wells are connected by the transverse drainage pipe sheets, and two adjacent longitudinally arranged water collection wells are connected by the longitudinal drainage pipe sheets. The crisscrossing arrangement of the longitudinal and transverse drainage pipe sheets divides the mud silo enclosure into several mud filtration zones.

[0012] A plurality of drainage pipes are laid at intervals at the bottom of the mud silo enclosure and above the impermeable geomembrane. Each drainage pipe is connected to the bottom of a corresponding plurality of water collection wells for discharging the water collected by the water collection wells outward.

[0013] In a preferred embodiment of this utility model, the mud reservoir enclosure is set up in the riverbed of the river to be dredged.

[0014] In a preferred embodiment of this utility model, the impermeable geomembrane is fixed to the top surface of the mud dam enclosure by a number of circumferentially spaced rivets.

[0015] In a preferred embodiment of this utility model, the drain pipe is connected to the water collection well using a socket-type interface, and the longitudinal drain pipe plate and the transverse drain pipe plate are connected to the water collection well using a slot-type interface.

[0016] In a preferred embodiment of this utility model, small filling tubes or bag-shaped earthen dams are provided on the inner and outer sides of the mud reservoir enclosure at the joint of the filling tube bag.

[0017] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model is applicable to a wide range of construction scenarios. It can adapt to complex environments and does not require digging and filling soil to build pits. River engineering can be arranged in the river channel where the flow is interrupted.

[0019] 2. This utility model utilizes the generated mud slurry to fill pipe bags to form a mud silo enclosure, thus solving the initial material problem;

[0020] 3. The present invention enables in-situ self-filtration and drying of mud, and enhances the efficiency of natural sedimentation filtration through the installation of drainage pipe plate, thereby shortening the sedimentation time, reducing the amount of external transportation and disposal, and does not involve any energy consumption, making it low-carbon, environmentally friendly and economical.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0025] See Figure 1 and Figure 2 The figure shows an environmentally friendly and land-saving mud silo structure, including a mud silo enclosure 100, an impermeable geomembrane 200, several drainage wells 300, several longitudinal drainage pipe panels 400, several transverse drainage pipe panels 500, and several drainage pipes 600.

[0026] The mud reservoir enclosure 100 is formed by enclosing mud-filled pipe bags 110 according to the site topography. This utility model is mainly applied to river dredging projects where there is no land space along the route to place the mud reservoir. Priority is given to placing the mud reservoir enclosure 100 in the riverbed of the river to be dredged. The specifications of the mud-filled pipe bags 110 are determined according to the depth of the mud reservoir. The pipe bags 110 use mature products, which are tubular geotechnical containers with water-filtering functions woven from materials such as polypropylene (PP) or polyester (PET). The mud-filled pipe bags 110 are laid along the available space, adaptable to any geological and topographical conditions, enclosing the outer contour of the mud reservoir, and using the filled mud slurry to filter water and form a mud-retaining dam. Small mud-filled pipe bags or bag-shaped earthen dams 120 are stacked on the inner and outer sides of the joints of the mud reservoir enclosure 100 and the mud-filled pipe bags 110 to improve the structural strength of the weak points of the mud reservoir enclosure 100.

[0027] The impermeable geomembrane 200 is laid at the bottom and around the mud silt enclosure 100 to prevent mud from seeping in and leaking. If the mud silt is located on land, it can avoid polluting the original surface environment with dredged sediment. The impermeable geomembrane 200 is fixed to the top surface of the mud silt enclosure 100 with several circumferentially spaced rivets 210, ensuring the connection stability of the impermeable geomembrane 200.

[0028] Several rows of water collection wells 300 are arranged longitudinally at intervals within the mud reservoir enclosure 100 and above the impermeable geomembrane 200. Each row of water collection wells 300 consists of several water collection wells 310 arranged laterally at intervals. The water collection wells 310 collect water filtered from the mud and enhance the overall stability of the drainage pipe plate system.

[0029] Two adjacent horizontally arranged water collection wells 310 are connected by a horizontal drainage pipe plate 500, and two adjacent vertically arranged water collection wells 310 are connected by a vertical drainage pipe plate 400. The vertical drainage pipe plate 400 and the horizontal drainage pipe plate 500 are connected to the water collection wells 310 by a slot-type interface. The vertical drainage pipe plate 400 and the horizontal drainage pipe plate 500 are made of mature plastic drainage boards, which are vertically inserted into the mud. The several vertical drainage pipe plates 400 and several horizontal drainage pipe plates 500 arranged in a crisscross pattern divide the mud silo enclosure 100 into several mud filtration zones 101, thereby increasing the mud filtration and drainage efficiency.

[0030] Several drainage pipes 600 are laid at intervals at the bottom of the mud silo enclosure 100 and above the impermeable geomembrane 200. Each drainage pipe 600 is connected to the bottom of a corresponding collection well 310. The drainage pipe 600 and the collection well 310 are connected by a socket joint, which is used to discharge the water collected in the collection well 310 to the outside. The diameter of the drainage pipe 600 is determined according to the drainage volume.

[0031] The construction method of this utility model for an environmentally friendly and land-saving mud silo structure includes the following steps:

[0032] Step S10: Lay mud-filling pipe bags 110 according to the site terrain conditions so that the mud-filling pipe bags 110 enclose the outer contour of the mud silo enclosure 100; if the mud silo is on land, the subsequent mud filling and drainage needs of the pipe bags need to be considered, and drainage ditches or water collection pits are set locally on the inner and outer sides of the mud-filling pipe bags 110.

[0033] Step S20: Pump various types of mud into the filling tube bag 110 using a mud pump and seal the bag, so that the filling tube bag 110 forms a mud silo enclosure 100 after filling with mud. When the construction period is tight, coagulant and flocculant are added to the mud pumped into the filling tube bag 110 to accelerate the caking of the mud in the tube bag. When the mud silo is deep, multiple layers of filling tube bags 110 need to be stacked. After the lower layer of tube bags is sealed, the upper layer of tube bags is laid and filled with mud.

[0034] Step S30: The impermeable geomembrane 200 is fully laid inside the mud dam enclosure 100 and extended along the surface of the mud filling pipe bag 110 to the outside of the mud dam enclosure 100. If necessary, several circumferentially spaced rivets 210 are used to fix the impermeable geomembrane 200 to the top surface of the mud dam enclosure 100. Small mud filling pipe bags or bag-shaped earthen dams 120 are set on the inside and outside of the joint of the mud dam enclosure 100 at the mud filling pipe bag 110 to improve the stability of the overall structure.

[0035] In step S40, several collection wells 300 are arranged longitudinally at intervals within the mud silo enclosure 100, and several longitudinal drainage pipe plates 400, several transverse drainage pipe plates 500, and several drainage pipes 600 are installed, so that the longitudinal drainage pipe plates 400 and the transverse drainage pipe plates 500 arranged in a crisscross pattern divide the mud silo enclosure 100 into several mud filtration zones 101.

[0036] In step S50, mud is pumped into several mud filtration zones 101 of the mud silo enclosure 100 using a mud pump. The mud level is lower than the top of the longitudinal drainage pipe plate 400, the transverse drainage pipe plate 500, and the water collection well 300.

[0037] In step S60, the mud silo operates normally, and the water collected in the collection well 300 is discharged using the drainage pipe 600.

[0038] In step S70, after the filtered mud has solidified, several longitudinal drainage pipe plates 400 and several transverse drainage pipe plates 500 are pulled out and the soil is removed by mechanical excavation.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
