Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blasting and compaction of soft soil foundation treatment, in particular to the technical field of filling of blasting and compaction. BACKGROUND

[0002] Blasting and compaction is a common method for treating soft soil and silt foundation in coastal areas. By using blasting to reduce the structural strength of silt, the riprap can sink into the silt under the action of gravity to replace the silt and stone.

[0003] The above method is essentially to replace the soft silt structure with riprap to improve the structural strength of the foundation. For example, a construction method for circular arc section blasting and compaction is disclosed in Chinese Patent No. CN106284290B, and a full-weather construction method for intertidal zone blasting and compaction is disclosed in Chinese Patent No. CN112729030A. The problem is that the above method requires a large amount of stone. For example, in a certain coastal area, the depth of silt can reach 20 to 60 meters. Assuming a silt depth of 20 meters, a roadbed height of 5 meters, and a road width of 10 meters, 25×10×1000 cubic meters (cubic meters) of stone are required for a 1-kilometer-long road, which is 250,000 cubic meters. Since 1 cubic meter of stone weighs about 2.5 tons, 625,000 tons of stone are required to build a 1-kilometer-long road. Coastal areas require a large amount of stone, but there is less available stone for development, and mining stone from nearby mountains destroys the local environment. It is becoming increasingly difficult to obtain the required stone nearby. Transporting stone from areas suitable for mining and transportation is very expensive compared to obtaining stone nearby, and the duration and cost of the project are likely to result in a loss.

DETAILED DESCRIPTION

[0043] To further clarify the technical means and effects taken by the present application to achieve the predetermined inventive purpose, the specific embodiments, structures, features and effects thereof according to the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0044] Referring to Figure 1 and Figure 2 , an embodiment 1 of a filling device of the present application is shown, which comprises a beam 2 and a support assembly for supporting the beam 2, the support assembly being adapted to be supported on a bearing layer 19. In this embodiment, the beam 2 is a reinforced concrete structure, with a length of 2 m-5 m, a cross-sectional width of 100 mm-500 mm, and a height of 100 mm-500 mm, and the support assembly is a reinforced concrete support column 3, which can also be other support structures, such as a support wall. Figure 2 A support structure formed by a plurality of filling devices 1 is shown. The filling device of the present application is combined with the blasting and silt-extruding method, the silt is first subjected to blasting to reduce the shear strength of the silt, and then the filling device 1 is vertically inserted into the bearing layer 19 below the silt, and the adjacent two filling devices 1 are connected and fixed by the steel plate 14, in this way, the plurality of filling devices 1 are connected, the upper surface of the filling device 1 is not higher than the surface of the silt, and the upper part of the steel plate can form a roadbed by filling stone and the like. It should be noted that in the above method, especially in the intertidal zone, the purpose of the blasting and silt-extruding operation is not to clear the silt by blasting, but to destroy the silt structure deposited in the original way, because the thickness of the silt in the coastal area is very large, if the silt structure is not destroyed, it is impossible to ensure that the filling device 1 described above is inserted smoothly into the bearing layer 19 of the foundation, there are two theories about the blasting and silt-extruding effect, one is the shear strength sudden drop theory, which believes that the total stress inside the silt does not change, and the total stress is the sum of the effective stress of the silt and the pore pressure, when blasting occurs, the pore pressure rises sharply, therefore the effective stress of the silt soil suddenly decreases, its value can reach zero, even negative, and the effective stress of the silt is closely related to its shear strength, this theory explains why blasting promotes the settlement of the riprap through the decrease of the shear strength of the silt; the other is the cavity theory, which believes that after blasting, the energy of the blasting is absorbed by the silt, causing a cavity inside the silt, i.e. the shear strength inside the silt is negative, the riprap moves into the cavity after entering the silt, and enters the bearing layer 19 through the cavity. The above principles are also the theoretical basis of the present application.

[0045] In the above embodiment 1, referring to Figure 1As shown, square or circular reserved holes 4 with side length 100 mm-300 mm or diameter 100 mm-300 mm are reserved at both ends of the beam 2, and the concrete support column 3 matched with the reserved holes 4 passes through the reserved holes 4, and the support column 3 is movable relative to the reserved holes 4 to adjust the distance between the bottom end of the support column 3 and the beam 2 to solve the problem of poor support caused by the height difference of the surface of the bearing layer, and the upper end of the support column 3 is 100 mm-500 mm higher than the upper surface of the beam 2. The column concrete hoop 5 or other forms of hoop is connected with the prefabricated part of the beam 2, and is fixed at the upper part of the interface between the support column 3 and the beam 2 or at the lower part of the interface between the column and the beam 2. In the above embodiment 1, with reference to Figure 1 As shown, a circular grouting pipe 6 with a diameter of 30 mm-60 mm is reserved at the center of the support column 3, the grouting pipe 6 includes an upper end opening and a lower end opening, and an air bag 7 is fixed at a position 30 mm-300 mm away from the bottom end of the support column 3, and the air bag 7 wraps the grouting pipe 6. It should be noted that in this embodiment, the grouting pipe 6 can be provided with multiple grouting holes on the side of the support column 3, but the structural strength of the support column 3 should be ensured, and the air bag 7 can wrap the bottom end of the support column 3 or only wrap the grouting hole, but sufficient embedding strength should be ensured, and the grouting is divided into open type and closed type, and the above method is closed grouting, that is, a rubber air bag is arranged at the lower end of the grouting pipe 6, and there is no gas in the air bag before grouting, which is convenient for structure installation, and after the structure reaches the designed elevation, grouting can be immediately carried out, and the grout enters the air bag to make the air bag full, and the air bag is much larger than the bottom area of the column. Open grouting can also be used in this embodiment, that is, no air bag is arranged outside the grouting hole, and the lower grouting hole is plugged with a plug before grouting, and the plug needs to be opened before grouting. The main functions of this embodiment include: 1. When the support column 3 is inserted into the bearing layer 19, concrete grouting is carried out at the lower end of the support column 3 through the grouting pipe 6, the inflation of the air bag 7 causes the bottom supporting structure 8 of the poured concrete to have a cross-sectional area (horizontal cross-sectional area) larger than that of the support column 3, thereby increasing the supporting area and reducing the settlement; 2. The upper surface of the bearing layer 19 is usually uneven, that is, not on a horizontal plane, and when part of the support column 3 is not well supported, grouting is carried out, and the concrete automatically flows to the area with lower pressure, thereby filling the area, thereby solving the problem of poor support of the filling structure of the present application.

[0046] Figure 3The embodiment 2 of the filling device 1 of the present application is shown, which is basically the same as the embodiment 1, and the difference is that the embodiment 2 includes four square frames 9 formed by the integrally formed reinforced concrete cross beams 2, and each of the four corners of the frame 9 is provided with a reserved hole 4, and each of the reserved holes 4 corresponds to one support column 3. Preferably, the diagonal of the frame 9 is connected with the reinforced concrete inclined beams 10, and the center points of the four corners of the frame 9 are connected with the inclined columns 11 which are directly below the center point of the frame 9, and the inclined columns 11 are the same height as the support columns 3, and the inclined columns 11 are connected to the connection points in the inclined direction by the reinforced concrete columns with the cross section of 100 mm-500 mm in length and 100 mm-500 mm in width, and the inclined columns 11 form the prefabricated parts with the cross beams 2, and the center of the inclined columns 11 is also provided with the grouting pipe 6, and the opening of the grouting pipe 6 at the lower end of the inclined column 11 is also provided with the air bag 7. The embodiment 2 is mainly suitable for smaller silt filling height, when H<3 m, the inclined columns 11 are connected to the point 1 m-2 m directly below the center point of the frame 9, when 3≤H<8, the inclined columns 11 are connected to the point 2 m-6 m below the center point of the frame 9, and the specific size can be selected and designed according to the depth of the silt.

[0047] The embodiment 2 is improved to be suitable for deeper silt filling height, Figure 6 The improved structure of the embodiment 4 is shown, which is basically the same as the embodiment 2, and the difference is that when H>8 m, the center points of the four corners of the frame 9 are connected to the point 4 m-8 m directly below the center point of the frame 9 in the inclined direction by the reinforced concrete columns. The center column 12 with the same cross section size is extended to the plane of the hollow frame 9 in the upward direction at the connection point, and the center column 12 is extended to the whole prefabricated part in the downward direction by 1 m-20 m, the extension size is determined by the thickness H of the soil silt, and the height is reserved to be sufficient to control and prevent the structure from being higher than the silt, and the grouting pipe 6 can also be provided on the center column 12.

[0048] In the above-mentioned embodiment 2 and embodiment 4, the square frame 9 can also be replaced by a rectangular frame, and the embodiment 3 is shown in the Figure 4 The embodiment 1 of the present application can also be understood as an embodiment in which the width of the embodiment 3 is reduced to zero, and the embodiment 2 can be understood as an embodiment in which the width and length of the frame 9 of the embodiment 3 are equal. In addition, the square in the embodiment 2 and the embodiment 4 can also be replaced by a rhombus or other polygons, and similar effects can also be achieved.

[0049] The present application also discloses a continuous filling structure for a road, which includes a plurality of the above-mentioned filling devices 1, in order to facilitate processing, the prefabricated parts of the filling devices 1 are designed to be completely the same size, and the length of the filling silt is L, the width is W, and the height is H, and the number of the filling devices 1 designed in the length direction is N x The number of the filling devices 1 designed in the length direction is N yThe number of filling devices 1 designed in the width direction, the units of length, width and height mentioned below are meters unless otherwise specified.

[0050] The following describes the continuous filling structure for roads using the filling device 1 with a rectangular frame structure as an example. When L>5 m, the length of the side of the frame 9 in the same (or parallel) direction along the length of the filling sludge can be selected as L / N x <5 m (m is the unit of length), the side can be the length or width of the rectangular frame, a reinforcing concrete structure with a 100 mm-300 mm long, 100 mm-200 mm wide, 200 mm-400 mm high circular reserved bolt hole with a diameter of 16 mm-30 mm is arranged at the center line position of the upper frame 9 of the filling device 1 on the side to be connected, and a bolt hole of the same size is reserved on the upper part of the side column, as shown in Figure 7 The connection method of the two filling devices 1 is steel plate bolt connection, a 20 mm-50 mm thick and 200 mm-400 mm wide steel plate 14 is arranged vertically on both sides of the reserved bolt hole, the length of the steel plate 14 is selected according to the actual distance on site, and is fixed by bolts through the reserved bolt hole, the gap in the middle of the adjacent filling device 1 is filled with a 40 mm-100 mm thick steel plate (not shown), which is fixed with expansion bolts and filling structure prefabricated parts, and the gap in the middle is filled with a 40 mm-100 mm thick steel plate, it should be noted that the adjacent filling device 1 does not need to be flush in height, the steel plate laid in the gap can have a certain activity space, and the steel plate can have a certain inclination or move within the design inclination angle.

[0051] In the above embodiment, when W>5 m, the length of the side of the frame 9 in the same (or parallel) direction along the width of the filling sludge can be selected as W / N y <5 m, a connecting piece 13 in the same direction as the length is arranged on the upper part of the structure on the side to be connected, and the connection method of the two devices and the selection method of the steel plate 14 are basically the same as in the length direction. It should be noted that the length of the side (length or width of the rectangular frame) of the frame 9 is less than 5 m, which is not a necessary feature of the present application, but a common or better selection made according to the strength and characteristics of the frame structure, and its length can be different according to the different road grades and design indexes, when the load of the road is larger, the size of the frame can be reduced, and vice versa, when the load of the road is smaller, the size of the frame can be appropriately increased, as long as the strength of the structure meets the requirements of the road grade, and the size is greater than 5 m.

[0052] In the above embodiments, the continuous filling structure can be laid horizontally or at a small angle, such as 15°. Here, the horizontal laying refers to the upper surface of the filling device or the upper surface of the adjacent filling device laid at a predetermined height difference. The small angle laying refers to the upper surface of the frame and the steel plate laid on the frame at a small angle. The upper surfaces of the adjacent two filling devices are generally in the same plane, and the transition section between the slope and the horizontal plane is not in the same plane. The steel plate 14 connected to the two adjacent filling devices 1 can be connected in a movable manner, such as the connection between the shaft sleeve and the shaft. When one or both of the devices is operated to produce different settlements, the steel plate can rotate at a certain angle, and the connection can still maintain stability and sufficient strength. The stone or concrete can be filled above the steel plate of the filling device 1 to form a roadbed. The height of the roadbed can be selected according to the design requirements.

[0053] The application also discloses a dam structure, which is described in detail below by taking the dam structure constructed by the filling device 1 of Embodiment 2 as an example.

[0054] In Embodiment 5, as shown in Figure 8 , the frame 9 on one side (mainly the side facing the sea) or both sides of the dam is provided with a slot 15, and a first steel plate 16 and a second steel plate 17 are inserted into the slot 15 to the bearing layer 19. The first steel plate 16 forms an acute angle with the horizontal plane, and the second steel plate 17 is perpendicular to the horizontal plane. The filling space 18 is formed between the first steel plate 16 and the second steel plate 17. The filling space 18 is filled with building materials, such as stones. Waterproof structures, such as concrete with water-stopping rubber structures or other waterproof structures, are arranged between the adjacent first steel plates 16 and / or the second steel plates 17. The dam structure of the application can reduce the use of a large amount of stones, has simple construction, and short construction period.

[0055] In Embodiment 6, as shown in Figure 9 , the two side edges of the dam are each provided with a slot 15, and a second steel plate 17 is inserted into the slot 15 to the bearing layer 19. The filling space 18 is formed between the two opposite second steel plates 17, and the filling space 18 is filled with building materials. Waterproof devices or structures are arranged between the adjacent second steel plates 17.

[0056] The filling of building materials in Embodiments 5 and 6 can strengthen the dam and be beneficial to waterproofing. In fact, Embodiments 5 and 6 can not fill any building materials at all. If the inside and outside of the dam do not need to block the flow of seawater, such as only for use in passing like a road, the first steel plate and the second steel plate in the structure are not necessary. When the flow of seawater between the inside and the outside of the dam needs to be blocked, the steel plates and the waterproof devices in Embodiments 5 and 6 can also be replaced by a surrounding structure. The surrounding structure is arranged on one side or both sides of the dam and is punched into the bearing layer. For reference, Figure 10 ,Figure 11 The specific mode includes:
