Description

Technical Field

[0001] The invention relates to the technical field of breach plugging and emergency rescue of dike projects, and in particular to a soil-replacing-stone permeable prism for rapid assembly for breach plugging and a construction method. Background Art

[0002] Flood disasters are a key issue facing survival and development, and we must always remain vigilant. In super-standard floods or extreme situations, dike projects are prone to breach risks, and may even gradually develop into large-scale breaches. Traditional breach blocking methods generally use shipwrecks, steel-wood-earth-rock composite dams, and steel cages and sandbags. Sometimes, local soil, stone and other materials are fully utilized, and machinery and manpower are used to close the gaps, and dike breaches are blocked during the non-flood season.

[0003] At present, the emergency rescue technology for dike breaches still has problems such as low modernization level and low efficiency. First of all, dike breaches are sudden in nature, and the location of the breach is difficult to predict in advance. In addition, the emergency rescue site generally has problems such as inconvenient on-site transportation, scarce flood control materials, and low efficiency of large-scale mechanical construction. The above factors will greatly reduce the efficiency of breach rescue. On the other hand, under rapid water flow, if only sandbags or gabions are thrown alone, it is easy for them to be washed away immediately.

[0004] Therefore, there is an urgent need for a soil-replacing-stone permeable prism and a construction method for quickly assembling breach plugging to solve the above-mentioned problems. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Reference Figure 1-Figure 7 The present invention provides a soil-replacing-stone permeable prism for rapid assembly and breach plugging, comprising a frame 1,

[0039] The frame 1 is provided with a filler, and the filler and the frame 1 form a water-permeable prism;

[0040] The filler includes a plurality of geobags 2 filled with soil. The plurality of geobags 2 form a reinforced body, and a gap is provided between the reinforced body and the inner wall of the frame 1 .

[0041] In one embodiment of the present invention, the geobag 2 confines the soil inside the bag to form a reinforced body, which can play the role of "replacing stone with soil". The frame 1 is a splicable structure, and the reinforced body formed by the geobag 2 is loaded to form a permeable prism to quickly seal the breach of the embankment project.

[0042] Specifically, the frame 1 is a box-shaped metal frame with sufficient strength and can be quickly assembled on site. The box-shaped metal frame can be made of steel pipes and assembled on site through connectors; it can also be made of sheet-shaped prefabricated parts and assembled on site.

[0043] Specifically, the metal frame is equipped with geobags 2, which can be directly bagged in the frame or quickly bagged by machinery; the geobags 2 in the metal frame can be rectangular or barrel-shaped geobags 2 with a cylindrical shape; there is no strict limit on the size of the geobags 2, which can be large, medium or small geobags 2. When bagging, an automatic geobag 2 bagging machine can be used to prepare the geobags 2 directly on the site, and a special grabber can be used to put the geobags 2 into the frame 1; the geobag bagging machine can be directly loaded with on-site soil and cooperated with an excavator.

[0044] According to a further optimized solution, the frame 1 includes a plurality of vertical members 11 and a plurality of horizontal members 12, and the plurality of vertical members 11 and the plurality of horizontal members 12 are spliced ​​into a frame of the frame 1 through connectors, and a plurality of connectors 13 are connected to the frame through connectors.

[0045] In one embodiment of the present invention, four vertical members 11 and four horizontal members 12 are used as the basic frame of the prism, and 30 connecting members 13 are used to strengthen the prism and increase its integrity. The lengths of the vertical members 11 and the horizontal members 12 approximately correspond to the height and length of the prism, respectively.

[0046] A further optimized solution is that a plurality of connecting plates 14 are axially fixedly connected to the vertical member 11 and the horizontal member 12, a plurality of connecting holes 3 are circumferentially provided on the connecting plates 14, grooves 4 are provided at both ends of the horizontal member 12 and the connecting member 13, the grooves 4 are adapted to the connecting plates 14, movable latch holes are provided on the grooves 4, and the movable latch holes and the connecting holes 3 are connected by movable latches 5.

[0047] In one embodiment of the present invention, the connection disk 14 is connected by a groove 4 and a movable latch 5 is inserted to ensure stability after connection. The connection disk 14 is approximately octagonal in shape with a circular hole in the center, and each corresponding side has an approximately trapezoidal connection hole 3.

[0048] Further optimization scheme, the vertical member 11, the horizontal member 12 and the connecting member 13 are all steel pipes, the connecting plate 14 is an octagonal structure, and the distance between the center of the octagonal structure and each vertex is required to be:

[0049] r≥r1+l1+l2+l3;

[0050] Where r1 is the radius of the steel pipe, l1 is the horizontal width of the movable pin hole, l2 and l3 are the distance of the movable pin hole close to the rod end and the distance of the movable pin hole to the outside, respectively.

[0051] To further optimize the scheme, the relationship between the major and minor principal stresses and the total cohesion calculation formula of geobag 2 in the ultimate state are as follows:

[0052]

[0053] In the formula, σ 1f and σ 3f K is the external stress acting on the soil in the geobag 2; p is equivalent to the passive earth pressure coefficient of the soil inside the geobag 2; T is the tension of the geobag 2 under the limit state; L, B and H are the length, width and height of the geobag 2 respectively; c is the cohesion of the soil; c T It is the additional cohesion of geobag 2.

[0054] According to a further optimized solution, the movable latch 5 is a curved structure with one end being small and the other end being large.

[0055] In one embodiment of the present invention, referring to Figure 6 The movable latch 5 is curved, and its shape tends to be "small at the top and large at the bottom", which can effectively prevent the latch from coming out from both sides.

[0056] According to the further optimization plan, the filling volume of geobag 2 shall not be less than 250kg.

[0057] In one embodiment of the present invention, the plane size of the geobag 2 should be no less than 170cm*100cm.

[0058] A construction method for quickly sealing a breach comprises the following steps:

[0059] Put soil into geobag 2 to prepare a reinforced body;

[0060] In one embodiment of the present invention, according to the needs of flood prevention, a certain number of rectangular geobags 2 are prepared in advance. There is no special restriction on the filler in the geobag 2. Various soils can be used, and solid wastes such as construction waste, urban construction waste, and non-toxic industrial waste can also be used. A portable sewing machine is used to seal the large geobag 2.

[0061] Splicing the frame 1 and placing the reinforced body in the frame 1 to prepare a water-permeable prism;

[0062] In one embodiment of the present invention, referring to Figure 7 , two horizontal members 12 and two connecting members 13 are used to form the bottom frame, three connecting members 13 are used to reinforce the bottom in the middle, four vertical members 11 are vertically arranged at the four vertices of the bottom frame, and the tops of the four vertical members 11 are connected by two connecting members 13 and two horizontal members 12 respectively, and connecting members 13 are added around the cubic frame, that is, fixed on the connecting plate 14, and the large geobag 2 is placed in the cubic frame, and the top of the cubic frame is closed by three connecting members 13.

[0063] The prepared permeable prisms are placed into the breach for sealing.

[0064] Further optimization scheme, the movement trajectory of the permeable prism after being put into the breach is S = (Sx ,S y ), the initial horizontal acceleration is The initial vertical downward acceleration is Where m is the mass of the permeable prism; g is the acceleration due to gravity; ρ is the density of water; v y is the vertical velocity of the permeable prism; C1 is the flow resistance coefficient; A x A is the projection area of ​​the permeable prism parallel to the horizontal plane; y is the projection area of ​​the permeable prism perpendicular to the water flow direction; V is the volume of the permeable prism;

[0065] The horizontal acceleration changes linearly as The vertical acceleration changes linearly as Where μ is the coefficient related to horizontal acceleration; λ is the coefficient related to vertical acceleration; and t is the time it takes for the permeable prism to fall to the bottom of the breach.

[0066] In one embodiment of the present invention, after the soil-replacing-stone permeable prism is thrown into the breach, its movement law and position after falling to the bottom play a key role in the effectiveness of the plugging operation. Based on the above, the movement process of the water flow when the permeable prism is used for breach plugging operation can be estimated in advance, and the position and time when the permeable prism falls to the bottom of the breach can also be obtained.

[0067] To further optimize the plan, the permeable prisms can be dropped by land, ship or airdrop.

[0068] In one embodiment of the present invention, when encountering a breach danger, a variety of flexible methods such as dump trucks and flood control ships are used to place the soil-replacing-stone permeable prisms into a fixed position.

[0069] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0070] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
