All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-9, a foundation supporting device for geotechnical engineering construction comprises fixed piles 11 fixedly inserted at the bottom of a foundation, a protective baffle 12 is installed between adjacent fixed piles 11, a diagonal bracing 13 is installed on the protective baffle 12, one end of the diagonal bracing 13 is connected to the protective baffle 12, the other end is connected to a supporting base 14, and the supporting base 14 is fixedly installed at the bottom of the foundation.

In the existing geotechnical engineering construction process, when facing a large foundation pit support with small depth, inclined column supports are generally adopted. As shown in fig. 1, the diagonal column supports are firstly provided with fixed column piles 11 along the edges of the foundation pit, and the adjacent fixed column piles 11 are connected by a protective baffle 12 for retaining soil. In order to enhance the supporting force of the protective baffle 12, a diagonal brace 13 is arranged on the inner side of the protective baffle 12, one end of the diagonal brace 13 is connected with the protective baffle 12, and the other end is connected with a supporting base 14 fixed on the bottom of the foundation. If the spacing between the adjacent fixed piles 11 is too small, the number of the fixed piles 11 is too large, the number of holes to be punched is large, the engineering quantity is increased, and the engineering efficiency is affected; if the distance between the adjacent fixed posts 11 is too large, the supporting force born by the protective baffle 12 is small, and in addition, in the practical use process, the protective baffle 12 may be stressed unevenly, and when the supporting point of the diagonal brace 13 is not just at the position where the protective baffle 12 is stressed greatly, the protective baffle 12 is very likely to deform under internal and external pressure, so that the foundation support is unstable. Therefore, as shown in fig. 1, the guide rail 15 is vertically arranged on the protective baffle 12, the horizontally arranged reinforcing plate 16 is slidably arranged on the guide rail 15, the inclined strut 13 supports the protective baffle 12 through the reinforcing plate 16, and the supporting force of the inclined strut 13 to a certain point of the protective baffle 12 is transmitted to the whole coverage area of the reinforcing plate 16, so that the stability of the supporting force of the inclined strut 13 is improved. The strength of the protective baffle 12 can be improved by the arrangement of the reinforcing plate 16, and the protective baffle 12 is prevented from being deformed under stress. On the basis, the invention also sets the diagonal braces 13 to be capable of sliding horizontally on the reinforcing plate 16 and the supporting base 14, so that the diagonal braces can find the maximum stress point on the protective baffle 12 for supporting according to actual conditions. As shown in fig. 1 and 6, the invention is provided with a sliding support 17 horizontally sliding on a reinforcing plate 16, a sliding base 18 horizontally sliding on a supporting base 14, and two ends of a diagonal brace 13 are respectively hinged with the sliding support 17 and the sliding base 18. Therefore, the inclined strut 13 can horizontally move to the position with larger stress on the protective baffle 12 to support, so that the protective baffle 12 is stressed stably, and the foundation supporting force is enhanced. The reinforcing plate 16 of the present invention can slide vertically on the guide rail 15, and the reinforcing plate 16 is fixed to the guard shield 12 by fastening bolts when moved to an appropriate height.
As a further scheme of the invention, a plurality of groups of pressure plates 21 are arranged on the protective baffle 12 at intervals along the horizontal direction, the pressure plates 21 are slidably arranged on the protective baffle 12, the sliding direction of the pressure plates 21 is consistent with the thickness direction of the protective baffle 12, and a rebound mechanism is arranged on the inner side of the pressure plates 21; the support base 14 is slidably mounted with a slide plate 22; the sliding base 18 is horizontally and slidably arranged on the sliding plate 22; the pressure plate 21 is connected with the sliding plate 22 through a connecting rod 23; the connecting rod 23 is movably connected with the sliding plate 22; a support spring 24 is provided between the support base 14 and the slide plate 22 along the sliding direction of the pressure plate 21.
After the fixed column piles 11, the protective baffle 12, the diagonal braces 13 and the supporting base 14 are arranged, soil filling and tamping are needed to be carried out on the outer side of the protective baffle 12 plate, and at the moment, the protective baffle 12 is stressed. The invention needs to move the diagonal brace 13 to the maximum stress position of the protective baffle 12 for supporting so as to improve the stability of the support. The present invention requires judgment of the maximum stress of the guard shield 12. As shown in fig. 3 and 7, the present invention includes pressure plates 21 provided at intervals on the guard plate 12, the pressure plates 21 sliding on the guard plate 12 in the thickness direction of the guard plate 12, and resilient mechanisms provided inside the pressure plates 21. The present invention provides a connecting rod 23 to connect the pressure plate 21 with the sliding plate 22. Thus, when the pressure plate 21 is stressed greatly, the pressed moving distance of the pressure plate 21 is increased, the sliding plate 22 is moved through the connecting plate, and by observing the displacement distance of the sliding plate 22, it can be easily judged which pressure plate 21 is stressed greatly, namely, the position of the protective baffle 12 is the position with the largest stress. The worker needs to move the movable slide mount 17 and the slide base 18, and move the diagonal brace 13 to the position to support. As shown in fig. 9, the connecting rods 23 of the present invention are movably connected with the sliding plate 22, so that when the moving distance of each connecting rod 23 is different, the sliding plate 22 is inclined under the action of the connecting rod 23, so that the sliding base 18 has a tendency of moving towards the connecting rod 23 with a larger moving distance, which is convenient for the operation of the staff and the movement.
As a further aspect of the present invention, the resilient mechanism is a compression spring fixedly provided on the guard shield 12.
The present invention provides an embodiment in which when the guard shield 12 is a compression spring, the compression spring is disposed between the guard shield 12 and the pressure plate 21 to provide a resilient force to the pressure plate 21.
As a further aspect of the present invention, the rebound mechanism includes a piston rod 31 fixedly connected to the pressure plate 21, a piston 32 is fixedly mounted at an end of the piston rod 31 away from the pressure plate 21, the piston 32 is slidably mounted in a cylinder 33, the cylinder 33 is filled with a liquid, and the liquids in the cylinders 33 are mutually communicated.
The present invention provides an embodiment, as shown in fig. 8, in which the rebound mechanism comprises a piston rod 31 fixedly connected to the pressure plate 21, the connecting rod 23 being fixedly connected to the piston rod 31. The piston 32 is attached to the end of the piston rod 31, and the piston 32 moves in the cylinder 33 to press the liquid in the cylinder 33 when the pressure plate 21 is pressed to move. Because the liquids in the respective cylinders 33 are communicated with each other, the liquids can flow in the respective cylinders 33 to transmit pressure, so that the pressure plate 21 having a smaller force can provide a supporting force for the pressure plate 21 having a larger force by the liquid through the liquid, thereby avoiding the pressure plate 21 from being excessively stressed. The hydraulic cylinder is adopted as the rebound mechanism, so that the rebound force can be provided for the pressure plate 21, the pressure plate 21 with smaller stress can provide supporting force for the pressure plate 21 with larger stress, and the situation that the pressure plate 21 is stressed too much and the protective baffle 12 is damaged is avoided.
As a further scheme of the invention, one end of the diagonal brace 13, which is close to the sliding support 17, is provided with a hinge rod 41, one end of the hinge rod 41 is hinged on the diagonal brace 13, and the other end is hinged on the sliding support 17; the inclined strut 13 is provided with a sliding block 42 in a sliding manner, the sliding block 42 slides along the extending direction of the inclined strut 13, the sliding block 42 is horizontally provided with a supporting rod 43, one end of the supporting rod 43 away from the sliding block 42 is fixedly provided with a supporting plate 44, the supporting plate 44 is arranged on the sliding support 17 in a sliding manner, and the sliding direction is consistent with the sliding direction of the pressure plate 21.
As shown in fig. 6, the diagonal brace 13 of the present invention has both a relaxed state and a tightened state. When the diagonal bracing 13 is loosened, the diagonal bracing 13 is positioned at the upper end of the hinging rod 41, and the diagonal bracing 13 has no supporting force on the protection plate, so that the position of the diagonal bracing 13 on the reinforcing plate 16 can be conveniently adjusted by the horizontal sliding of a worker. When the diagonal brace 13 supports the reinforcing plate 16, the hinge rod 41 is turned downwards, the diagonal brace 13 is positioned at the lower end of the hinge rod 41, and the diagonal brace 13 tightens the reinforcing plate 16 to provide supporting force. According to the invention, when the hinge rod 41 is turned downwards and the diagonal brace 13 is tightly supported, the sliding block 42 which is slidably arranged on the diagonal brace 13 and the diagonal brace 13 slide relatively. As shown in fig. 6, since the slide block 42 is always kept constant in height by the arrangement of the support rods 43, the diagonal braces 13 slide downward with respect to the slide block 42 and drive the slide block 42 forward to move. The sliding block 42 moves forward to drive the supporting plate 44 to slide on the sliding support 17 through the supporting rod 43, so as to support the protective baffle 12, and further improve the supporting force of the diagonal brace 13 on the protective baffle 12. According to the invention, the hinge rod 41 is arranged at one end of the diagonal brace 13 close to the protective baffle 12, the stress state of the diagonal brace 13 can be freely adjusted by changing the state of the hinge rod 41, when the hinge rod 41 is positioned below the diagonal brace 13, the diagonal brace 13 is not stressed, the sliding support 17 and the sliding base 18 can be freely moved, and the diagonal brace 13 can be conveniently and freely moved to find the maximum stress point of the protective baffle 12; when the hinge rod 41 is located above the diagonal bracing 13, the diagonal bracing 13 is stressed, so that the diagonal bracing 13 can provide supporting force for the protective baffle 12 through the protection plate, and the supporting plate 44 can be driven to move forwards simultaneously to provide supporting force for the protective baffle 12, so that the supporting effect is better.
As a further aspect of the present invention, the guide rail 15 is a dovetail groove type. As shown in fig. 1, the dovetail rail 15 is provided for the purpose of facilitating the vertical sliding of the reinforcing plate 16 on the barrier 12 while preventing the reinforcing plate 16 from being separated from the barrier 12.
As a further scheme of the invention, an interface groove 51 for inserting the protective baffle 12 is formed on the fixed post 11, and the interface groove 51 is I-shaped; the two ends of the protective baffle 12 are provided with I-shaped interfaces 52, and two adjacent interfaces 52 are spliced in the same interface groove 51. As shown in fig. 1 and 2, the protective baffle 12 of the present invention is inserted between two adjacent fixing posts 11 in a block manner, thus facilitating the installation of workers. In order to prevent the protective baffle 12 from being unstable and moving after the installation is completed, the invention is provided with an I-shaped interface groove 51 on the fixed post 11, and an I-shaped interface 52 is also arranged on the protective baffle 12. Therefore, the two protective baffles 12 are inserted into the same interface groove 51 to limit displacement, so that the protective baffles 12 can be fixed conveniently.
As a further scheme of the invention, the bottom of the fixed pile is also provided with a guide ring sleeve 61, and the guide ring sleeve 61 is provided with a neck extension plate 62 for guiding the fixed pile 11 to be inserted into the foundation soil layer; the guide ring 61 is fixedly provided with an anti-tilting plate 63 for preventing the guard shield 12 from being detached from the interface groove 51, and the guard shield 12 is interposed between the neck extension plate 62 and the anti-tilting plate 63. As shown in fig. 3 and 4, in the process of inserting the fixing post pile 11 into the bottom of the foundation, it is necessary to ensure the vertical insertion of the fixing post, so that the subsequent insertion of the protective baffle 12 can be ensured to be vertical, and better supporting force is provided. The present invention provides a guide collar 61 at the bottom of the foundation. When the fixing posts 11 are inserted, a proper interval is selected, and the guide ring 61 is fixedly installed at the bottom of the foundation. The neck extension plate 62 vertically arranged on the guide ring 61 forms a ring to match the shape of the bottom surface of the fixed post 11. The fixing posts 11 are then inserted into the soil at the bottom of the foundation along the guides of the neck extension plates 62, ensuring vertical insertion. When the fixed post 11 is inserted, the protective baffle 12 is installed, and the protective baffle 12 is just inserted between the neck extension plate 62 and the anti-tilting plate 63 after the installation is completed, the anti-tilting plate 63 prevents the protective baffle 12 from being separated from the interface slot 51, and the vertical of the protective baffle 12 is ensured.

Then, a supporting base 14 is fixedly arranged at a place which is at a proper distance from the protective baffle 12, two ends of the diagonal brace 13 are respectively hinged on the sliding support 17 and the sliding base 18, and the diagonal brace 13 is in a relaxed state and does not provide supporting force; the connecting plate is movably connected with the sliding plate 22. At this time, the outside of the protective baffle 12 is filled with soil and tamped, so that the pressure plate 21 on the protective plate is moved under pressure, the moving distance is reflected on the supporting base 14 through the connecting rod 23, the observation of staff is facilitated, the staff can adjust the position of the diagonal bracing 13 according to the moving distance, move the diagonal bracing 13 to the position with the maximum stress of the protective baffle 12, then press down the diagonal bracing 13, so that the hinge rod 41 is turned over, and the diagonal bracing 13 is in a tightening state. The diagonal braces 13 drive the supporting plates 44 to move forward to further support the protective baffle 12 while being tightened, so that the supporting capability is improved. According to the invention, when the position of the reinforcing plate 16 needs to be further adjusted after the installation is finished, the inclination angle of the diagonal brace 13 needs to be synchronously changed, the vertical height of the reinforcing plate 16 is easy to adjust, and the reinforcing plate is fixed by loosening and tightening bolts. However, the length of the diagonal brace 13 is fixed, and the supporting base 14 is also fixedly installed at the bottom of the foundation, so that the adjustment is inconvenient. As shown in fig. 7, the support spring 24 provided in the present invention not only provides a supporting force for the slide plate 22, but also provides a space for the subsequent angular change of the diagonal braces 13.
