[0029] As shown in Figures 1 to 4 The reinforced pile 100 of the preferred embodiment of the present application comprises a pile body 1 and a reinforcing structure 2, wherein the reinforcing structure 2 is installed on the pile body 1 for reinforcing the pile body 1, and the reinforcing structure 2 comprises a first reinforcing member 21 and a second reinforcing member 23.
[0030] The reinforcing structure 2 of the present application is used to reinforce the pile body 1. According to the background art, the wood pile used in soft soil foundation treatment can be specifically pine pile, rather than the commonly used reinforced concrete pile. The wood pile can be driven into a deeper soil layer and improve the compactness and bearing capacity of the foundation by extruding the surrounding soil. However, due to the material of the wood pile itself, the support stability provided by the wood pile cannot be guaranteed.
[0031] Specifically, the pile top 11 of the pile body 1 is provided with a first mounting groove, which is in the shape of an inverted circular table; the first reinforcing member 21 in the reinforcing structure 2 is placed in the first mounting groove of the pile body 1, and the first reinforcing member 21 is in the shape of an inverted circular table and tightly fits the first mounting groove.
[0032] At the same time, the height of the first reinforcing member 21 is higher than the groove depth of the mounting groove, which can better uniformly transmit the load of the superstructure to the pile body 1 or other foundation structure, which helps to reduce local stress concentration and ensure the safety and stability of the entire structure. The cross-sectional height of the first reinforcing member 21 is also increased, thereby improving its compressive strength and carrying capacity.
[0033] Specifically, the second reinforcing member 23 is sleeved on the pile bottom 12, which can protect the bottom of the pile body 1 from erosion by underground water and microorganisms, prolonging the service life of the pile body 1. During the piling process, the second reinforcing member 23 can reduce the direct contact wear between the pile bottom 12 and the soil body, maintain the shape and size of the pile bottom 12, and ensure the bearing performance of the pile body 1. The second reinforcing member 23 can effectively disperse the load of the pile bottom 12 of the pile body 1, reduce the local pressure on the soft soil foundation, and improve the stability of the foundation.
[0034] Specifically, the second reinforcing member 23 comprises a pile tip 231 and a plurality of first fixing plates 232 fixedly arranged at one end of the pile tip 231 away from the tip of the pile tip 231, and a second mounting groove is arranged in the pile tip 231, and the pile bottom 12 of the wooden pile body 1 is placed in the second mounting groove, and the side surface of the pile bottom 12 is attached with the first fixing plate 232.
[0035] Specifically, the pile tip 231 can be made of cast steel, and the cast steel has high hardness and can better penetrate the soft soil layer. The external structure of the pile tip 231 is a pyramid, such as a three-pyramid, a four-pyramid or a cone, which has a pointed end. The second mounting groove in the pile tip 231 has a shape matched with the pile bottom 12, for example, the pile bottom 12 is cylindrical, and the second mounting groove is a circular groove. If the pile bottom 12 is conical, the second mounting groove is a reverse conical groove, so that the pile bottom 12 of the wooden pile body 1 can be completely installed and fixed in the second mounting groove. The pile tip 231 can also protect the pile bottom 12 and prevent the wooden pile body 1 from moving laterally in the soft soil foundation, thereby maintaining the verticality and stability of the pile.
[0036] Specifically, in order to stably install the pile tip 231 on the pile bottom 12 of the wooden pile body 1, the first fixing plate 232 is arranged on the side of the pile tip 231 away from the tip, and the first fixing plate 232 is installed on the side wall of the pile bottom 12 of the wooden pile body 1 by screws. The number of first fixing plates 232 can be two, three or four. The first fixing plate 232 can be a low-carbon steel strip, and the size of the first fixing plate 232 can be 45*7mm.
[0037] The embodiment of the utility model discloses the second reinforcing member 23 at the pile bottom 12 of the wooden pile body 1 to protect the wooden pile body 1 from being damaged, and the strength of the wooden pile body 1 is strengthened, the lateral movement of the wooden pile body 1 in the soft soil foundation is prevented, and the verticality and stability of the wooden pile body 1 are maintained.
[0038] In some embodiments, the reinforcing structure 2 further comprises a first fastener 22, which is arranged around the outer side wall of the first reinforcing member 21 protruding from the first mounting groove, and the two ends of the first fastener 22 protrude from the first reinforcing member 21.
[0039] Specifically, the first fastener 22 can be a reinforcing bar, which can constrain the first reinforcing member 21 and limit its lateral expansion, thereby improving the compressive strength of the first reinforcing member 21. When the first reinforcing member 21 is subjected to axial compression, the first fastener 22 prevents the first reinforcing member 21 from cracking and expanding along the crack, so that the first reinforcing member 21 can still maintain integrity under higher pressure.
[0040] Preferably, the first fastener 22 can be A6 steel bar, which is a first-class steel bar with a diameter of 6 mm, has good plasticity and strength, and can bear large tension and pressure, thereby improving the safety and stability of the first reinforcing member 21.
[0041] Specifically, the first mounting groove has a groove depth of 100 mm, the part of the first reinforcing member 21 protruding from the first mounting groove has a height of 500 mm, and the diameter of the first bottom surface of the first reinforcing member 21 is 20 mm smaller than the diameter of the second bottom surface of the first reinforcing member 21.
[0042] The first bottom surface is the lower bottom surface of the first reinforcing member 21, that is, the bottom surface of the first reinforcing member 21 abutting the first mounting groove, and the second bottom surface is the upper bottom surface of the first reinforcing member 21, that is, the bottom surface of the first reinforcing member 21 contacting the object supported above.
[0043] Referring to Figs. 1 and 2, Figure 1 and Figure 3 In some embodiments, the pile bottom 12 of the wood pile body 1 is a quadrangular pyramid, and the reinforcing structure 2 further comprises a second reinforcing member 23, which is sleeved on the pile bottom 12.
[0044] Specifically, the quadrangular pyramid-shaped bottom can increase the contact area between the wood pile body 1 and the foundation soil, thereby improving the carrying capacity of the wood pile body 1. The tapered design enables the pile end pressure to be more uniformly transmitted to the foundation, which helps to reduce the damage to the soft soil foundation and improve the stability of the foundation. The quadrangular pyramid-shaped bottom is easier to penetrate into the soft soil layer than the flat bottom pile due to its sharp shape, which reduces the resistance and energy required during piling.
[0045] In some embodiments, the first fixing plate 232 is arranged on each side surface of the pile bottom 12.
[0046] Specifically, since the pile bottom 12 of the wood pile body 1 is a quadrangular pyramid, it has four side surfaces, and one side surface is provided with one batten, so that one second reinforcing member 23 is provided with four battens.
[0047] The embodiment of the utility model discloses one first top plate on each side surface of the pile bottom 12 of the wood pile body 1, which can ensure that the second reinforcing member 23 is stably installed on the pile bottom 12 of the wood pile body 1.
[0048] In some embodiments, the pile tip 231 and the first fixing plate 232 are integrally formed.
[0049] Referring to Figs. 1 and 2, Figure 1 and Figure 4As shown, in some embodiments, the reinforcing structure 2 further comprises a third reinforcing member 24, which comprises a plurality of second fixing plates 241 vertically arranged on the outer sidewall of the pile body 1 and a plurality of connecting bodies 242 connecting two oppositely arranged second fixing plates 241.
[0050] Specifically, the third reinforcing member 24 is used to stabilize the middle end of the pile body 1, or to fixedly connect two pile bodies 1.
[0051] Preferably, the number of second fixing plates 241 can be two, four, or other even numbers, and the second fixing plates 241 are uniformly arranged along the circumference of the outer sidewall of the pile body 1.
[0052] Preferably, the connecting body 242 can be a chemical bolt, and the specific model can be M14 chemical bolt. First, drill holes on the second fixing plate 241 and the pile body 1, then remove the dust and dirt in the holes, insert a medicine tube into the clean hole, and use an electric drill to screw in the screw rod until the medicine flows out, then wait for the medicine to harden, and after the medicine is completely hardened, add a washer and a hex nut to fix the object, so that the connecting body 242, the second fixing plate 241, and the pile body 1 form an integral whole, thereby fixing the second fixing plate 241 and improving the load-bearing capacity of the pile body 1.
[0053] The embodiment of the utility model can significantly improve the stability and load-bearing performance of the structure of the pile body 1 by setting the third reinforcing member 24.
[0054] In some embodiments, the length of the second fixing plate 241 is four times the diameter of the pile body 1.
[0055] Specifically, setting the length of the second fixing plate 241 to be four times the diameter of the pile body 1 can ensure that there is a long enough area in the middle part of the pile body 1 to evenly distribute the stress generated by external loads, effectively reducing stress concentration and improving the overall load-bearing capacity of the pile body 1. At the same time, the length of four times the diameter of the pile body 1 can provide a longer lateral support surface, which is particularly effective in resisting lateral soil pressure and water pressure, thereby reducing the lateral displacement of the pile body 1. It can also increase the contact area between the pile body 1 and the surrounding soil, thereby increasing the friction, which is very important for improving the stability and load-bearing capacity of the pile body 1.
[0056] If the third reinforcing member 24 is used to fixedly connect two pile bodies 1, the length of one second fixing plate 241 arranged in contact with two pile bodies 1 is equal, that is, one half of the second fixing plate 241 is arranged in contact with one pile body 1 and the other half is arranged in contact with the other pile body 1.
[0057] Specifically, when the length of the second fixing plate 241 is four times the diameter of the pile body 1, four connecting bodies 242 are evenly arranged on the two oppositely arranged second fixing plates 241, and the second fixing plate 241 and the two pile bodies 1 are connected to form a whole.
[0058] The utility model sets up third reinforcing structure 2 and the length of second fixing plate 241 is four times the diameter of pile body 1, can reach the strong node effect of the shear capacity of pile joint part is stronger than the pile body.
[0059] The working process of the utility model is as follows: a first installation groove in the shape of an inverted round table is arranged on the pile top 11 of the pile body 1, and then the first reinforcing member 21 is placed in the first installation groove; the pile bottom 12 of the pile body 1 is arranged in the shape of a quadrangular pyramid, and the second reinforcing member 23 is sleeved on the pile bottom 12 of the pile body 1, wherein the pile tip 231 is fixedly arranged on the pile bottom 12 of the pile body 1 by the first fixing plate 232; a plurality of third reinforcing members 24 are arranged at the middle position of the pile body 1 or the connection position of the two pile bodies 1. When the soft soil foundation needs to be reinforced, the pile body 1 with the reinforcing structure 2 is driven into the soft soil, and the first reinforcing member 21 can be used as a pile cap to contact with the weight.
[0060] In summary, the utility model embodiment provides a reinforcing structure, which is provided with a first installation groove in the shape of an inverted round table on the pile top of the pile, and a first reinforcing member matched with the shape of the first installation groove is arranged in the first installation groove, so that the contact area of the first reinforcing member and the pile is increased, and the stability of the connection is improved. The first installation groove in the shape of an inverted round table is arranged on the pile top of the pile body, and the first reinforcing member matched with the shape of the first installation groove is arranged in the first installation groove, so that the contact area of the first reinforcing member and the pile is increased, and the stability of the connection is improved.
