Description

Technical Field

[0001] The utility model relates to the technical field of supporting structures, in particular to a steel sheet pile supporting system for excavating soil slopes for cultural relics protection. Background Art

[0002] When constructing water conservancy projects, cultural relics are sometimes dug up when digging pipes. Therefore, it is necessary to build protection facilities on site to protect the cultural relics accordingly. After the cultural relics are discovered, earth slopes are usually excavated around the cultural relics, eventually forming a rectangular or various complex shaped foundation pits to protect the cultural relics in the foundation pits pending subsequent protective excavation work. At the same time, in order to ensure that the earth slopes of the foundation pits will not collapse or collapse, thereby damaging the cultural relics, supporting structures such as steel sheet piles, stabilizing beams and supporting beams are usually set on the surface of the earth slopes while digging the earth slopes. These are used to support the inner wall of the foundation pit.

[0003] In the prior art, when digging soil slopes and constructing foundation pits, if it rains, since there is no rainproof structure in the protection system of the foundation pit, rainwater will directly fall into the foundation pit and accumulate in the foundation pit. If the accumulation is large, it may damage the ground in the foundation pit, causing the ground to collapse. At the same time, cultural relics will be soaked in rainwater, which may cause certain damage to the cultural relics. At the same time, after rainwater enters the foundation pit, the construction space in the foundation pit will be reduced, and personnel will not be able to smoothly construct in the foundation pit. In addition, rainwater will also invade the soil layer in the foundation pit or between the foundation pit and the support system, causing changes in soil quality, thereby leading to the collapse of the foundation pit.

[0004] Therefore, there is an urgent need for a support system that can stabilize the soil slopes around the foundation pit while also having good rain protection capabilities. Utility Model Content

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying 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 construed as a limitation of the present utility model.

[0050] In addition, terms such as "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0051] In addition, terms such as "horizontal", "vertical", "hanging" do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0053] It should be noted that the features in the embodiments of the present utility model can be combined with each other without conflict.

[0054] It should be understood that when a water conservancy project is being built and cultural relics are unearthed, it is necessary to dig a foundation pit 400 and adopt a support system of steel sheet piles 110, stabilizing beams 300 and supporting beams 500 to protect the cultural relics. However, in the above support system, when it rains, due to the lack of a rain shielding structure, when it rains, effective rain protection measures cannot be taken for the foundation pit 400, and thus rainwater accumulates in the foundation pit 400, causing the cultural relics to be soaked in the accumulated rainwater, which has an impact on the cultural relics. During this period, the accumulation of rainwater in the foundation pit 400 will also prevent construction workers from smoothly carrying out construction, and it is relatively difficult to clean up later. Moreover, when the rainwater soaks into the soil slope 410 around the foundation pit 400, it will also affect the soil layer of the soil slope 410, resulting in problems such as the sliding and collapse of the soil layer of the soil slope 410 and the unstable connection between the steel sheet pile 110 and the soil slope 410, thereby damaging the cultural relics.

[0055] To improve the above problems, as Figure 1 and Figure 2 shown, the present embodiment provides a steel sheet pile support system for excavating the soil slope 410 for cultural relic protection, including a plurality of steel sheet piles 110, a plurality of stabilizing beams 300, supporting beams 500, support rods 600 and a plurality of shielding members 700, so that while the soil slopes 410 around the foundation pit 400 are stable, it also has good rain protection ability.

[0056] Among them, when excavating the foundation pit 400, the shape of the foundation pit 400 can be determined according to the environment, such as polygonal shapes like rectangular bodies, cylinders, etc. In this embodiment, for the convenience of description and according to the common shape of the foundation pit 400, the foundation pit 400 adopts a rectangular body structure. When excavating the foundation pit 400, four soil slopes 410 are excavated towards the surroundings, and the four physical slopes are connected to form a rectangular foundation pit 400.

[0057] According to the above foundation pit 400, in this embodiment, as Figure 1 , Figure 4 , Figure 5 and Figure 8 shown, a plurality of steel sheet piles 110 are connected to each other in pairs to form a steel sheet pile wall 100. The steel sheet pile wall 100 has four walls, and the four walls are respectively arranged on the four soil slopes 410, and the steel sheet piles 110 of the four walls are all inserted into the foundation pit 400 in the vertical direction and are attached to and abutted against the soil layer of the soil slope 410, thereby stabilizing the soil layers of the four soil sides. Among them, the steel sheet piles 110 adopt Larsen steel sheets.

[0058] In this embodiment, as Figure 1 and Figure 2As shown, the four walls of the steel plate enclosure 100 are connected pairwise, and the steel sheet piles 110 forming the steel plate wall are connected pairwise. A plurality of stabilizing beams 300 are all arranged on the surfaces of the four walls of the steel plate wall. Specifically, a plurality of stabilizing beams 300 are arranged horizontally on the surface of the steel plate enclosure 100, and the plurality of stabilizing beams 300 arranged on the wall of the same steel plate enclosure 100 are arranged at intervals in the vertical direction in sequence, so that the stabilizing effect of the support system on the foundation pit 400 is relatively strong.

[0059] The support beam 500 is arranged between two walls, and both ends of the support beam 500 are respectively connected to two stabilizing beams 300 at the same depth. Specifically, the support beam 500 can be arranged between two stabilizing beams 300 at the same height between different walls. The support beam 500 presses against and supports the stabilizing beam 300, thereby stabilizing the connection between the steel plate enclosure 100 and the soil slope 410 from different positions.

[0060] In this embodiment, as Figures 1 - 5 shown, the number of the support beams 500 is multiple. The multiple support beams 500 are arranged at intervals between different walls of the steel plate wall, and both ends of each support beam 500 are between two stabilizing beams 300 at the same height between different walls, thereby making the connection and relative position between the steel plate enclosure 100 and the soil slope 410 stable.

[0061] In this embodiment, as Figure 1 and Figure 2 shown, a plurality of support rods 600 are all arranged on different or the same stabilizing beam 300. Specifically, the same number of support rods 600 are respectively arranged on two oppositely arranged stabilizing beams 300 that are closest to the top end of the foundation pit 400 and are located on different walls. Among them, the support rods 600 are perpendicular to the stabilizing beam 300 and one end of the support rod 600 is connected to the stabilizing beam 300.

[0062] The shielding member 700 includes a shielding plate 730, a plurality of shielding rollers 710 and a plurality of shielding curtains 720. Among them, the shielding plate 730 can adopt structures such as a rectangular body and a cylindrical body. In this embodiment, in order to adapt to the foundation pit 400, the shielding plate 730 adopts a rectangular body.

[0063] Furthermore, the plurality of support rods 600 arranged on two different stabilizing beams 300 respectively support the lower surface of the shielding plate 730, so that the force on the shielding plate 730 is relatively uniform, and the four end faces of the shielding plate 730 respectively face the four soil slopes 410 of the foundation pit 400. Specifically, the four end faces of the shielding plate 730 are parallel to the planes where the four soil slopes 410 are located.

[0064] The number of the shielding rollers 710 is multiple. In this embodiment, the number of the shielding rollers 710 is four. The four shielding rollers 710 are respectively arranged on the four cross sections of the shielding plate 730. The number of the shielding curtains 720 is the same as that of the shielding rollers 710, and the four shielding curtains 720 are respectively wound around the outer walls of the four shielding rollers 710, so that the shielding curtains 720 can be stored and extended by the rotation of the shielding rollers.

[0065] Among them, as Figure 1 and Figure 2 shown, fixing members 200 are respectively arranged on the four walls of the steel plate enclosure wall 100. Specifically, two of the multiple steel sheet piles 110 forming the wall are respectively provided with fixing members 200, and the distance between the two fixing members 200 is the same as the width of the shielding curtain 720. When the shielding curtain 720 rotates around the shielding roller 710 and extends to the wall facing the end face of the shielding plate 730 where the shielding roller 710 is located, one end of the shielding curtain 720 is detachably connected to the corresponding fixing member 200, so that the shielding curtain 720 is fixed. At this time, the shielding curtains 720 located at the end faces of different shielding plates 730 all extend to the corresponding walls and are connected to the corresponding fixing members 200 on the walls, thereby shielding the space above the foundation pit 400 and preventing rain from entering the foundation pit 400.

[0066] Among them, as Figure 1 , Figure 2 and Figure 9 shown, one end of the shielding curtain 720 is provided with a hook 3000 and a length adaptor 3100. Specifically, the length adaptor can adopt a connecting spring, so that when the shielding curtain 720 is connected to the fixing member 200, under the action of the connecting spring, it can automatically adapt to the distance between the shielding curtain 720 and the fixing member 200, avoiding a large distance between the shielding curtain 720 and the fixing member 200 and thus being unable to be fixed. The fixing member 200 adopts a fixing ring.

[0067] Among them, the shielding roller 710 is an elastic converging member. When the shielding curtain 720 extends, the shielding roller 710 has a continuous converging force on the shielding curtain 720, so that after the shielding curtain 720 is connected to the fixing member 200, the shielding curtain 720 is in a taut state. When the shielding curtain 720 is detached from the fixing member 200, the shielding curtain 720 can be automatically converged on the shielding roller 710 under the converging force of the shielding roller 710.

[0068] In this embodiment, the baffle 730 is arranged on the upper side of the foundation pit 400. After the shielding curtain 720 is fixedly connected, the shielding curtain 720 is in an inclined state. And due to the elastic restraint of the shielding roller 710, the shielding curtain 720 is in a taut state and there will be no wrinkles on the surface. When rainwater falls on the shielding curtain 720, under the action of gravity, it will slide down along the surface of the shielding curtain 720, so that it will not accumulate on the surface of the shielding curtain 720. As a result, it is more difficult to retract the shielding curtain 720, and it is also possible to prevent rainwater from accumulating on the shielding curtain 720, which may cause the shielding curtain 720 to deform under the action of the accumulated rainwater, thereby reducing the rainwater shielding effect.

[0069] Among them, the width and length of the baffle 730 are the same as the width or length of the foundation pit 400. In this embodiment, the width of the baffle 730 is the same as the width of the foundation pit 400, so that the two shielding curtains 720 in the length direction of the baffle 730 completely shield the upper space of the foundation pit 400. At the same time, the two shielding curtains 720 in the width direction of the baffle 730 can also shield most of the rainwater on the side. And the two shielding curtains 720 in the width direction of the baffle 730 are located directly below the baffle 730. The length and width of the baffle 730 can be selected according to the local rainfall intensity. For example, when the local rainfall is large, the length and width of the baffle 730 can be set to be the same as the length and width of the foundation pit 400 to ensure that the space around the upper side of the foundation pit 400 is completely shielded.

[0070] In some embodiments, as Figure 1 and Figure 5 shown, the support system further includes a water collecting trough 800. The water collecting trough 800 is in the shape of a groove with an upward opening. Among them, the water collecting trough 800 is continuously arranged around the outer wall of the steel sheet pile wall 100, so that the water collecting trough 800 surrounds the steel sheet pile wall 100. When the shielding curtain 720 is connected to the fixing member 200, the opening of the water collecting trough 800 is located below one end of the shielding curtain 720, so that the rainwater on the shielding curtain 720 flows into the water collecting trough 800 for collection, preventing more rainwater from falling near the steel sheet pile wall 100 and then entering the soil layer of the soil slope 410, which may make the soil layer soft and cause the connection between the steel sheet piles 110 and the soil layer to be unstable.

[0071] In some embodiments, as Figure 1 and Figure 5 shown, the support system further includes a drainage pump 900. Specifically, the drainage pump 900 is connected to the water collecting trough 800 through a pipeline, and the water outlet end of the drainage pump 900 can be arranged in a nearby water source or a specially set bucket, so that the rainwater in the water collecting trough 800 is discharged, and thus the rainwater falling from the shielding curtain 720 can be continuously collected.

[0072] In some embodiments, asFigure 1 , Figure 6 and Figure 7 As shown in Figure 7 , the shielding member 700 is further provided with a wiper blade and an elastic connecting member 750. Specifically, the number of the wiper blade and the elastic connecting member 750 is multiple, and the number of the wiper blade and the elastic connection is the same. The elastic connecting member 750 can adopt structures such as a spring and a rubber cord. In this embodiment, the elastic connecting member 750 adopts a spring. The wiper clamping plate 740 has a wiper opening 741. One ends of multiple shielding curtains 720 respectively pass through the wiper openings 741 of multiple wiper clamping plates 740, and two surfaces of the shielding curtain 720 are respectively attached to the inner walls of the wiper openings 741. Two ends of the wiper clamping plate 740 are respectively connected to the shielding plate 730 through the elastic connecting member 750, so that the wiper blade displaces relative to the shielding curtain 720. When the rain stops, the wiper blade is controlled to displace relative to the shielding curtain 720, and the wiper blade hangs the remaining rainwater on the shielding curtain 720 onto the water collecting tank 800. Then, under the action of the elastic connecting member 750, the wiper blade displaces along the shielding curtain 720 and resets to the position of the shielding plate 730. Furthermore, when the shielding curtain 720 is retracted, there is less rainwater on the shielding curtain 720, and less rainwater will not fall into the foundation pit 400 when retracting.

[0073] Among them, as Figure 1 , Figure 2 and Figure 10 shown, a plurality of first connecting rods 1000 are sequentially arranged at intervals on the lower surface of the shielding plate 730. A second connecting rod 2000 is arranged on the side surface of the wiper blade facing the shielding plate 730. One end of the first connecting rod 1000 is provided with a first connecting plate 1100, and one end of the second connecting rod 2000 is provided with a second connecting plate 2100. The first connecting plate 1100 and the second connecting plate 2100 are both connected to the elastic connecting member 750. Specifically, the first connecting rod 1000 is hinged to the shielding plate 730 and the first connecting plate 1100, and the second connecting rod 2000 is hinged to the wiper blade and the second connecting plate 2100, so that the first connecting rod 1000 can rotate relative to the shielding plate 730 and the first connecting plate 1100, and the second connecting rod 2000 can rotate relative to the wiper blade and the second connecting plate 2100. Among them, the number of the first connecting rod 1000 and the second connecting rod 2000 is the same as the number of the elastic connecting member 750 and is arranged close to the elastic connecting member 750. Thus, when the wiper blade displaces relative to the shielding curtain 720, the first connecting rod 1000 and the second connecting rod 2000 can rotate, so that the body of the elastic connecting member 750 will not undergo a large bending deformation, and further the connection between the elastic connecting member 750 and the first connecting rod 1000 and the second connecting rod 2000 is stable.

[0074] Among them, a plurality of elastic connecting members 750 are sequentially arranged at intervals on the lower surface of the shielding plate 730.

[0075] In some embodiments, as Figures 6 - 7As shown in the figure, a wiper cushion layer 742 is provided on the inner wall of the wiper water outlet 741. Specifically, the wiper cushion layer 742 can adopt structures such as a wiper brush or a rubber brush. In this embodiment, the wiper cushion layer 742 adopts a rubber brush. Moreover, a plurality of adaptive springs 743 are provided between the wiper cushion layer 742 and the inner wall of the wiper water outlet 741. The plurality of adaptive springs 743 are arranged at intervals in sequence between the inner wall of the wiper water outlet 741 and the wiper cushion layer 742, so that the wiper cushion layer 742 is always in contact with the surface of the shielding curtain 720 under the action of the adaptive springs 743.
