Description

Technical Field

[0001] The present invention relates to an earth and sand accumulation and removal system and an earth and sand accumulation and removal method.

Background Art

[0002] At a construction site where excavation work such as excavation construction or pneumatic caisson construction is carried out, the excavated earth and sand generated are often temporarily accumulated in an earth and sand pit provided within the construction site and then carried out of the site. There are various purposes for the temporary accumulation in this earth and sand pit. As an example, there is a case of temporary accumulation when the excavated earth and sand generated cannot be promptly carried out of the site. As another example, when the excavated earth and sand contain a large amount of moisture, an improvement material is added to and mixed with the excavated earth and sand in the earth and sand pit to generate improved soil, and then the mixing with the improvement material when carrying it out of the site is involved.

[0003] However, when the above-described excavation work is carried out at a construction site in an urban area, a case often occurs where an earth and sand pit with a sufficient planar scale cannot be formed at the construction site, and a sufficient amount of excavated earth and sand cannot be temporarily accumulated. That is, when temporarily accumulating excavated earth and sand in an earth and sand pit, it is not enough to secure a space (referred to as the first space) for the earth and sand pit. A space (the second space) for the operation and movement of heavy equipment such as a backhoe or a crane, which is used when accumulating or carrying out excavated earth and sand to the earth and sand pit, needs to be secured around the first space. Therefore, the first space for the earth and sand pit formed at a narrow construction site inevitably becomes narrow, and as a result, it leads to the inability to temporarily accumulate a sufficient amount of excavated earth and sand.

[0004] Therefore, in a construction site where excavation work is carried out, which requires a first space for a soil pit to temporarily accumulate excavated soil and a second space for the operation and movement of heavy machinery used during the accumulation and removal of excavated soil, there is a need for a soil accumulation and removal system and method that can increase the first space for the soil pit as much as possible, thereby enabling the temporary accumulation of a sufficient amount of excavated soil.

[0005] Here, Patent Document 1 proposes a facility for collecting and transporting excavated soil. This facility is installed at the construction site of a shield tunneling project and is a facility for collecting and transporting excavated soil that is temporarily collected and transported by transport vehicles such as dump trucks. It comprises a soil pit for collecting the excavated soil and a mobile transport machine that travels on a guide rail installed directly above the soil pit and loads the excavated soil in the soil pit onto the transport vehicle. The mobile excavation equipment has a swingable bucket and is equipped with a mobile backhoe that moves along guide rails using electric power. Furthermore, the guide rails are installed on the second floor of a soundproof house that covers the outside of the soil pit, a hopper for loading excavated soil is provided on the floor of the second floor of the soundproof house, and the first floor of the soundproof house is configured to allow transport vehicles to enter and exit directly below the hopper. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2004-204590 [Overview of the project] [Problems that the invention aims to solve]

[0007] According to the excavated soil collection and removal equipment described in Patent Document 1, it is possible to reduce the space required for the soil pit. However, this collection and removal equipment requires a mobile backhoe that moves along guide rails using electric drive, and therefore does not maximize the space required for the soil pit while utilizing general heavy machinery. Furthermore, it is a large-scale facility, which may lead to soaring construction costs.

[0008] The present invention aims to provide a soil accumulation and removal system and method that can increase the space for the soil pit as much as possible and realize the temporary accumulation of a sufficient amount of excavated soil at a construction site where excavation work is performed, which requires space for a soil pit to temporarily accumulate excavated soil and space for the operation and movement of heavy machinery used when accumulating and removing excavated soil. [Means for solving the problem]

[0009] To achieve the aforementioned objective, one embodiment of the soil and sand collection and transportation system according to the present invention is: A soil collection and removal system for temporarily accumulating excavated soil in a soil pit set up at a construction site where excavation work is carried out, and for transporting the accumulated excavated soil, A guide rail is provided above the aforementioned soil pit, A traveling frame that travels along the aforementioned guide rail, A heavy machine is used to board the vehicle onto the vehicle platform from the vicinity of the soil pit, to retreat from the vehicle platform back to the vicinity of the soil pit, and to collect and transport the excavated soil. The system is characterized by having a first control panel that controls the movement and stopping of the aforementioned travel platform.

[0010] According to this embodiment, the heavy machinery used for accumulating and transporting excavated soil is configured to board and retreat from the vicinity of the soil pit to a traveling platform that moves along guide rails installed above the soil pit. This allows the heavy machinery to be operated above the soil pit while using general heavy machinery, thereby eliminating the need for space for the heavy machinery to move and operate around the soil pit and maximizing the space of the soil pit. For this reason, the soil accumulation and transport system according to this embodiment is suitable for construction sites where it is difficult to secure sufficient space for the soil pit, such as construction sites where excavation work is carried out in urban areas. Here, the plan view shape of the soil pit includes various shapes depending on the available space at the construction site, including rectangles and squares. Furthermore, "excavated soil is accumulated in the soil pit" includes not only the literal accumulation of the excavated soil in the soil pit, but also the addition of soil improvement materials to the excavated soil accumulated in the soil pit, which is then mixed with heavy machinery to produce improved soil. Furthermore, the phrase "the guide rails are installed above the soil pit" includes, for example, configurations in which a pair of guide rails are installed on top of a pair of retaining walls such as steel sheet piles along the extension direction of the soil pit, which is rectangular in plan view (for example, the longitudinal direction of the soil pit), or configurations in which they are installed on the ground or roadbed surrounding (outside) a pair of retaining walls such as steel sheet piles, or configurations in which a pair of guide rails are spanned within the planar dimensions of the soil pit (inside in plan view). Among these, the configurations in which the guide rails are installed on top of the retaining walls or on the roadbed surrounding the retaining walls are preferable because the guide rails are stably supported by the retaining walls or roadbed, and furthermore, the absence of guide rails inside the planar dimensions of the soil pit improves workability by heavy machinery and suppresses interference between heavy machinery and guide rails.

[0011] Furthermore, the first control panel for controlling the movement and stopping of the traveling platform may be installed around the soil pit, or it may be installed in a management building such as a work office within the construction site. For example, it is preferable that the worker operating the first control panel and the operator of the heavy machinery coordinate their work using verbal signals or wireless communication, stopping the operation of the heavy machinery when the traveling platform is moving and starting the operation of the heavy machinery after the traveling platform has been positioned in a predetermined location.

[0012] Furthermore, in another embodiment of the soil and sand collection and transportation system according to the present invention, The aforementioned heavy machine comprises a lower traveling body, an upper rotating body stacked on the lower traveling body so as to be rotatable, a boom and arm rotatably mounted on the upper rotating body, and a bucket rotatably mounted on the arm. Of the aforementioned travel frame, the width perpendicular to the extension direction of the guide rail is such that the heavy machine cannot change direction. The aforementioned travel platform is provided with a stopper at one end facing the other across the aforementioned width, and an entrance for the heavy machinery at the other end. The heavy machinery is mounted on the traveling frame from the direction perpendicular to it to form a stopping position, and while in this stopping position, the upper rotating body rotates and the boom, arm and bucket rotate, and the heavy machinery moves away to the surrounding area from the direction perpendicular to it.

[0013] According to this embodiment, the width of the travel frame perpendicular to the extension direction of the guide rails is set to a width that makes it impossible for the heavy machinery to change direction, a stopper is provided at one end of the travel frame opposite to the said width, and an entrance for the heavy machinery is provided at the other end, the heavy machinery is mounted and stopped from the direction perpendicular to the travel frame, and the excavated soil is accumulated and transported by rotating the upper rotating body of the heavy machinery and rotating the boom, arm and bucket, thereby preventing the heavy machinery from falling from the travel frame into the soil pit, and enabling the heavy machinery to be mounted on and taken away from the travel frame in the narrowest possible space.

[0014] Furthermore, other embodiments of the soil and sand collection and transportation system according to the present invention include: The device is characterized by having a step between the surrounding area and the vehicle platform, and by having a tapered ramp connecting the step at the entrance.

[0015] According to this embodiment, when there is a step between the surrounding area and the travel platform, a slope is provided at the entrance that connects the step in a tapered manner, allowing heavy machinery to enter and exit the travel platform stably and smoothly. As described above, regardless of whether the guide rail is installed on a pair of retaining walls along the extension direction of the soil pit, on the roadbed etc. around the retaining walls (outside), or spanned within the planar dimensions of the soil pit, a step is bound to occur between the roadbed or ground around the soil pit and the travel platform which is freely movable on the guide rail. Therefore, the above effect is achieved by installing a slope with sufficient rigidity to withstand the weight of the heavy machinery at the step at the entrance.

[0016] Furthermore, in another embodiment of the soil and sand collection and transportation system according to the present invention, The guide rail comprises a first length section corresponding to the length of the soil pit along the extension direction, and a second length section. The traveling frame is moved to align with the second length section of the guide rail, and the excavated soil is collected and transported out by the bucket.

[0017] According to this embodiment, the guide rail comprises a first length section corresponding to the length of the soil pit along the extension direction and a second length section, and the traveling frame is positioned in the second length section of the guide rail to allow for the accumulation and removal of excavated soil by heavy machinery. This makes it easier to accumulate and remove excavated soil, especially in the end area of ​​the soil pit (area near the retaining wall), where accumulation and removal by heavy machinery is difficult.

[0018] Furthermore, in another embodiment of the soil and sand collection and transportation system according to the present invention, The heavy machine includes a second control panel that controls the rotation of the upper slewing body and the rotation of the boom, the arm, and the bucket. The first control panel and the second control panel are electrically connected to each other via power switching means that prevent simultaneous operation of both.

[0019] According to this aspect, the second control panel of the heavy machine and the first control panel that controls the traveling and stopping of the traveling base are electrically connected to each other via power switching means that prevent simultaneous operation of both. This effectively suppresses, in addition to the tipping accident of the heavy machine that may occur when the heavy machine operates during the traveling of the traveling base, interference between the boom, arm, bucket of the heavy machine and the wall surface (such as soil retaining) of the working pit.

[0020] Also, one aspect of the earth and sand accumulation and removal method according to the present invention is as follows. An earth and sand accumulation and removal method for temporarily accumulating the excavated earth and sand generated in an earth and sand pit provided at a construction site where excavation work is carried out, and carrying out the accumulated excavated earth and sand, A heavy machine for accumulating and carrying out the excavated earth and sand is mounted on a traveling base that travels along a guide rail provided above the earth and sand pit from the periphery of the earth and sand pit. The traveling base travels along the guide rail and is aligned, and the heavy machine accumulates or carries out the excavated earth and sand. The heavy machine retreats from the traveling base to the periphery.

[0021] According to this aspect, by allowing a heavy machine for accumulating and carrying out excavated earth and sand to board and retreat from the periphery of an earth and sand pit with respect to a traveling base that travels along a guide rail provided above the earth and sand pit, the heavy machine can be operated above the earth and sand pit while using a general heavy machine. Therefore, the space for the heavy machine to move and operate around the earth and sand pit can be eliminated, and the space of the earth and sand pit can be increased as much as possible.

Effects of the Invention

[0022] According to the soil accumulation and removal system and method of the present invention, in a construction site where excavation work is performed, which requires space for a soil pit to temporarily accumulate excavated soil and space for the operation and movement of heavy machinery used during the accumulation and removal of excavated soil, it is possible to increase the space for the soil pit as much as possible and realize the temporary accumulation of a sufficient amount of excavated soil.

[Modes for carrying out the invention]

[0024] The following description of the soil accumulation and removal system and soil accumulation and removal method according to the embodiment will be given with reference to the attached drawings. In this specification and drawings, substantially identical components may be denoted by the same reference numerals to avoid redundant explanations.

[0025] [Soil and sediment collection and removal system and method according to an embodiment] An example of a soil and sediment collection and removal system and method according to the embodiment will be described with reference to Figures 1 to 6. Here, Figure 1 is a plan view of an example of a construction site to which the soil collection and removal system according to the embodiment is applied. Figure 2A is a view of the soil pit located at the corner of the construction site shown in Figure 1, taken along the arrow AA. Figure 2B is a view of the soil pit located at the corner of the construction site shown in Figure 1, taken along the arrow BB. Figure 3 is an enlarged view of part III of Figure 2B, showing a cross-sectional view of the structure that fixes the guide rail to the roadbed. Figure 4 shows the state in which the heavy machinery is boarding the travel platform from the vicinity of the soil pit, and then the state in which it has stopped on the travel platform and the upper rotating body has rotated. Furthermore, Figure 5 is a side view of an example of the soil collection and removal system according to the embodiment, taken from the side, showing the state in which the heavy machinery on the travel platform is rotating its arm and inserting the bucket into the soil pit. Figure 6 is a view of the soil collection and removal system according to the embodiment, taken along the arrow VI in Figure 5, and is a plan view of the soil collection and removal system according to the embodiment, taken from above.

[0026] The construction site D shown in Figure 1 is a site where, for example, in an urban area, the ground is excavated to a predetermined depth using the pneumatic caisson method, and a new building is constructed to be erected from underground to above ground. As shown in the figure, in the center of construction site D is an excavation area E1 where excavation is carried out by multiple pneumatic caissons M3, and two narrow areas surrounding it are designated as soil collection and removal areas E2 and E3.

[0027] In the soil collection and removal area E2, a soil pit P is formed, separated by retaining walls T made of steel sheet piles, where a portion of the excavated soil generated in the excavation work area E1 is temporarily collected. In addition, several backhoes M1 and M2 (an example of heavy machinery) (two in the illustrated example) are installed around the soil pit P so that they can be operated and moved freely for the purpose of collecting and removing the excavated soil.

[0028] Meanwhile, in the other soil accumulation and transport area E3, a rectangular soil pit 10 is formed in plan view, separated by a retaining wall 15 made of steel sheet piles. In this soil pit 10, a portion of the excavated soil generated in the excavation work area E1 is temporarily accumulated. Here, the temporary accumulation of excavated soil in soil pits 10 and P at the construction site D shown in the illustration means that when the groundwater level in the area of ​​construction site D is relatively high and the excavated soil excavated by the pneumatic caisson method contains a large amount of moisture, the excavated soil is accumulated in soil pits 10 and P, and an improvement material is added to the accumulated excavated soil and mixed to produce improved soil. Once a certain amount of improved soil has been generated and accumulated in soil pits 10 and P, the improved soil is loaded onto vehicles such as dump trucks and transported off-site.

[0029] As shown in Figure 1, the space around one soil pit 10 is narrower than the space around the other soil pit P. Therefore, if space is to be secured around it for the movement and operation of backhoes M1 and M2, as is the case with the other soil pit P, the planar dimensions of soil pit 10 become very narrow, making it difficult to accumulate a sufficient amount of excavated soil. To address this, the soil pit 10 is equipped with the soil accumulation and removal system 100 shown in Figures 5 and 6, thereby eliminating the need for backhoe operating space around the soil pit 10 and maximizing the planar dimensions of the soil pit 10.

[0030] Returning to Figure 1, the soil collection and removal area E3 is provided with a rectangular soil pit 10 in plan view, which has a cubic space with a floor laid to a predetermined depth, as shown in Figures 2A and 2B, which are views of the arrows AA and BB, respectively. As shown in Figure 1, guide rails 20 are installed on the outside of a pair of soil retaining walls 15 that are aligned along the longitudinal direction of the rectangle, and this longitudinal direction is the direction in which the guide rails 20 extend, as shown in Figure 2A. Although not shown in the illustration, for example, a cap may be attached to the top of the soil retaining wall 15, and the guide rail may be installed on the cap, that is, the soil retaining wall 15 may support the guide rail.

[0031] As shown in Figure 2B and Figure 3, which is an enlarged view of part III, the guide rail 20 is made of H-shaped steel, and a reinforced concrete roadbed 22 supporting the guide rail 20 is provided in the ground G. The roadbed 22 has a strip shape that extends along the extension direction of the guide rail 20, and is formed by embedding multiple main reinforcements 23 extending in the extension direction and multiple hoop reinforcements 24 surrounding the multiple main reinforcements 23 in concrete.

[0032] The lower flange of the guide rail 20 is fixed to the roadbed 22 via a pair of L-shaped anchor bolts 21. Multiple anchor bolts 21 are provided at intervals in the direction of extension of the guide rail 20.

[0033] The soil accumulation and removal system 100 includes the guide rails 20 described above, a traveling platform 30 that travels along the guide rails 20, a backhoe 40 (an example of heavy machinery) that boards the traveling platform 30 from the vicinity of the soil pit 10, moves back from the traveling platform 30 to the vicinity of the soil pit 10, and accumulates and removes excavated soil, and a first control panel 50 that controls the travel and stopping of the traveling platform 30.

[0034] A pair of guide rails 20 are fitted with a traveling frame 30, as shown in Figures 4 to 6, that can move freely. The traveling frame 30 consists of a square-shaped stage 31 in plan view (see Figure 6), a pair of motors 36 mounted below the stage 31, and wheels 35A that are directly rotated by the drive of each motor 36, and wheels 35B that are not directly rotated by the drive of the motors 36. Two wheels 35A and 35B form a pair and are fitted to each guide rail 20.

[0035] A handrail 32 is attached to the upper surface of the stage 31 along its outer edge. A stopper 34 is provided at one end 31a of the stage 31 on the side of the guide rail 20, and an access opening 33 for the backhoe 40 is provided at the handrail 32 at the other end 31b.

[0036] Of the stage 31, the width in the direction perpendicular to the extension direction of the guide rail 20 is set to a width that makes it impossible for the lower traveling body 41 of the backhoe 40 to change direction.

[0037] The backhoe 40 comprises a lower traveling body 41, an upper slewing body 43 stacked on the lower traveling body 41 so as to be rotatable in the Y1 direction, a boom 46 mounted on the upper slewing body 43 so as to be rotatable in the Y2 direction, an arm 47 mounted on the boom 46 so as to be rotatable in the Y3 direction, and a bucket 48 (attachment) mounted on the arm 47 so as to be rotatable in the Y4 direction. The boom 46 rotates on the upper slewing body 43 via a boom cylinder 49A, the arm 47 rotates on the boom 46 via an arm cylinder 49B, and the bucket 48 rotates on the arm 47 via a bucket cylinder 49C.

[0038] The upper rotating body 43 is equipped with a cabin 45 in which the operator sits, and the cabin 45 is fitted with a second control panel (not shown). The operation of each part of the backhoe 40 is controlled via the second control panel by the operator sitting in the cabin 45.

[0039] As shown in Figure 4, the backhoe 40 boards the stage 31 of the travel platform 30 via the access opening 33, in the X1 direction from a direction perpendicular to the extension direction of the guide rail 20. When retreating from the stage 31, it similarly retreats to the vicinity of the soil pit 10 in the same perpendicular direction.

[0040] Here, a step Q of a predetermined height exists between the ground surface surrounding the soil pit 10 and the traveling frame 30 which is freely mounted on the guide rail 20. Therefore, a slope 60 is installed at the entrance 33 to connect the step Q in a tapered shape.

[0041] Slope 60 has the load-bearing capacity for the backhoe 40 to pass over it, and can be made of steel blocks, hard resin blocks, expanded polystyrene (EPS) blocks, etc.

[0042] The backhoe 40 boards the travel platform 30 in the X1 direction via the slope 60 from the vicinity of the soil pit 10, and forms a stopping position with a part of the lower travel body 41 in contact with the stopper 34 at one end 31a of the stage 31. Next, by rotating the upper slewing body 43 in the Y1 direction while in the stopping position, a ready position for operation for accumulating and transporting excavated soil is formed.

[0043] Subsequently, as shown in Figure 5, the traveling platform 30 on which the backhoe 40 is mounted moves along a pair of guide rails 20 to the desired position and stops, and the excavated soil is accumulated and removed from the soil pit 10 by the rotation of the boom 46, arm 47, and bucket 48 of the backhoe 40. By sequentially moving the traveling platform 30 to the desired position on the guide rails 20, it becomes possible to accumulate and remove excavated soil from the entire area of ​​the soil pit 10.

[0044] Here, as shown in Figures 5 and 6, the guide rail 20 comprises a first length section 20A corresponding to the longitudinal length of the soil pit 10 along the extension direction, and two second length sections 20B located at both ends thereof.

[0045] Thus, because the guide rail 20 has a length that includes a second length section 20B, for example, when accumulating or removing excavated soil near the retaining wall 15 in the short direction of the soil pit 10, the traveling platform 30 can be aligned with the second length section 20B, making it easier to accumulate and remove excavated soil by the backhoe 40 near the retaining wall 15.

[0046] Furthermore, a stopper 25 is provided at the end of the second length section 20B, and the absorber 37 at the end of the running frame 30 contacts the stopper 25 without impact, causing the running frame 30 to stop at the end of the guide rail 20.

[0047] Furthermore, the second control panel, which is installed in the cabin 45 of the backhoe 40, and the first control panel 50, which controls the movement and stopping of the traveling frame 30, are electrically connected to each other via a power switching means (not shown) that prevents simultaneous operation of both.

[0048] Here, both the first control panel 50 and the second control panel are composed of computers, and each has a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), wireless communication device, display device, and input device, which are connected via a system bus for data communication. The ROM stores various programs and data used by those programs. The RAM is used as a storage area for loading programs stored in the ROM and as a work area for the loaded programs.

[0049] For example, if the first control panel 50 is equipped with a power switching mechanism, and a worker operates the power switching mechanism to turn on the motor 36 of the travel platform 30, the power to the second control panel of the backhoe 40 is turned off. Therefore, no parts of the backhoe 40 will operate while the travel platform 30 is moving.

[0050] Next, the motor 36 is driven to move the travel platform 30 along the guide rail 20 to the desired position and stop it. Then, when the worker operates the power switching means to turn OFF the motor 36 of the travel platform 30, the power to the second control panel of the backhoe 40 is turned ON.

[0051] When the operator of the backhoe 40 receives notification from the workers that all parts of the backhoe 40 are ready to operate, the operator starts the backhoe 40 to collect and remove the excavated soil from the soil pit 10. The mobile platform 30 does not move during the operation of the backhoe 40.

[0052] By sequentially repeating the above operations, simultaneous operation of the mobile platform 30 and the backhoe 40 is impossible, while the mobile platform 30 can be moved to the desired position, and the backhoe 40 can collect and remove excavated soil at the desired position. This effectively suppresses accidents such as the backhoe 40 tipping over or interference between the backhoe 40's bucket 48 and the retaining wall 15, which may occur if the backhoe 40 is operated while the mobile platform 30 is moving, thereby ensuring construction safety.

[0053] According to the soil accumulation and removal system 100, the width of the traveling frame 30 perpendicular to the extension direction of the guide rail 20 is set to a width that makes it impossible for the backhoe 40 to change direction. The backhoe 40 is mounted on the traveling frame 30 from this perpendicular direction and contacts the stopper 34 to form a stopping position. While in this stopping position, the excavated soil is accumulated and removed while the upper slewing body 43 and boom 46 etc. are rotated, thereby eliminating the space required for the backhoe 40 to move and operate around the soil pit 10, and increasing the space of the soil pit 10 as much as possible.

[0054] Furthermore, it is possible to prevent the backhoe 40 from falling from the travel platform 30 into the soil pit 10, while enabling the backhoe 40 to enter and exit the travel platform 30 in the narrowest possible space.

[0055] Furthermore, other embodiments may be used in which other components are combined with the configurations listed in the above embodiments, and the present invention is not limited in any way to the configurations shown herein. In this regard, modifications can be made without departing from the spirit of the present invention, and can be appropriately determined according to the application form. [Explanation of symbols]
