Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 - Figure 8 An inclined support pile structure for foundation pit support includes a support mechanism 1, which is installed on a soil body 2 and a capping beam 4. A vertical pile 3 is poured into the inner cavity of the soil body 2, and a capping beam 4 and a support beam 5 are poured into the top of the vertical pile 3. A support hole 6 is opened at the top of the support beam 5, and a support base 7 is poured into the inner cavity of the soil body 2. The support mechanism 1 includes an inclined support component 11, and a vertical support component 12 is inserted into the outer wall of the inclined support component 11; In the above structure, holes are drilled in the soil body 2, and then vertical piles 3 are poured in the air. Then, a crown beam 4 and a support beam 5 are poured on the top of the vertical piles 3. Support holes 6 are reserved on the support beam 5. Then, a support base 7 is poured after the top of the soil body 2 is opened. Then, the vertical support component 12 is placed in the support base 7, and then the inclined support component 11 is installed in the support beam 5, so that the inclined support component 11 is inserted into the vertical support component 12. The vertical piles 3 and the crown beam 4 are inclinedly supported by the cooperation of the inclined support component 11 and the vertical support component 12.

[0021] The inclined support assembly 11 includes an inclined support steel 1101. A limiting plate 1102 is installed on the top of the inclined support steel 1101. A worm gear 1103 is installed on the top of the limiting plate 1102. An adjusting base 1107 is installed on the top of the worm gear 1103. A locking rod 1108 is provided on the inner wall of the adjusting base 1107. A locking groove 1109 is opened at the end of the locking rod 1108 away from the adjusting base 1107. A pre-embedded column 1116 is provided on the inner wall of the locking groove 1109. A baffle plate 1117 is installed on the outer edge of the pre-embedded column 1116. The vertical support assembly 12 is located at the end of the inclined support steel 1101 away from the limiting plate 1102. In the above structure, the locking rod 1108 and the embedded column 1116 work together. The rotation of the worm gear 1103 drives the locking rod 1108 to rotate, allowing the locking rod 1108 to separate from the embedded column 1116. At this time, the inclined support steel 1101 can be pulled out from the support hole 6, gradually separating the inclined support steel 1101 from the vertical support steel 1201, thus losing its supporting effect. When support is needed, the inclined support steel 1101 is inserted into the support beam 5. In the support hole 6, the limiting plate 1102 comes into contact with the support beam 5, and then the worm gear 1103 is rotated, causing the worm gear 1103 to drive the locking rod 1108 to rotate, gradually causing the locking groove 1109 on the locking rod 1108 to be locked on the embedded column 1116. At this time, the blocking plate 1117 on the embedded column 1116 blocks the locking rod 1108, so that the inclined support steel 1101 cannot be disengaged from the support hole 6 on the support beam 5. This structure is easy to assemble and disassemble, improving construction efficiency.

[0022] The vertical support assembly 12 includes a vertical support steel 1201. A square groove 1202 is formed on the outer wall of the vertical support steel 1201. A bottom support frame 1206 is provided at the bottom of the inner cavity of the square groove 1202. A top support frame 1213 is provided at the top of the bottom support frame 1206. An inclined support steel 1101 is located between the bottom support frame 1206 and the top support frame 1213. The vertical support steel 1201 is located in the support base 7.

[0023] In the above structure, through the setting of the bottom support frame 1206 and the top support frame 1213, since the head of the inclined support steel 1101 is conical, the head of the inclined support steel 1101 can be between the bottom support frame 1206 and the top support frame 1213, and the distance between the bottom support frame 1206 and the top support frame 1213 can be adjusted. After adjustment, the top support frame 1213 is fixed so that the inclined support steel 1101 cannot move forward between the bottom support frame 1206 and the top support frame 1213. By limiting the inclined support steel 1101 through the bottom support frame 1206 and the top support frame 1213, the inclined support steel 1101 inserted into the vertical support steel 1201 can support the vertical pile 3.

[0024] In a preferred embodiment: a plurality of baffle plates 1117 are provided, and the plurality of baffle plates 1117 are evenly distributed on the embedded column 1116, which is located around the support hole 6.

[0025] In the above structure, the setting of several blocking plates 1117 makes the embedded column 1116 have multiple connection points, which facilitates the flexible adjustment between the inclined support steel 1101 and the vertical support steel 1201. When the vertical support steel 1201 is close to the vertical pile 3, the locking rod 1108 can be connected to the top position close to the embedded column 1116, and then the vertical support steel 1201 is lifted upward so that the inclined support steel 1101 can be connected to the vertical support steel 1201.

[0026] In a preferred embodiment: a mounting bracket 1106 is installed on the top of the limiting plate 1102, a worm gear 1104 is movably connected to the inner wall of the mounting bracket 1106, a locking nut 1105 is installed on the outer edge of the worm gear 1104, the worm gear 1104 meshes with the worm wheel 1103, and a protective cover 1115 is installed on the top of the limiting plate 1102.

[0027] In the above structure, by connecting the power output end of the electric wrench to the locking nut 1105, the operation of the electric wrench drives the worm gear 1104 to rotate. When the worm gear 1104 rotates, it drives the worm wheel 1103 to rotate. Therefore, when the worm wheel 1103 rotates, it drives the adjusting base 1107 and the locking rod 1108 to rotate.

[0028] In a preferred embodiment, the outer edge of the locking rod 1108 is provided with an internal threaded hole 1110, and the inner wall of the internal threaded hole 1110 is threaded with an adjusting bolt 1114.

[0029] In the above structure, by adjusting the setting of the bolt 1114, since the embedded column 1116 is an embedded part, errors may occur during the pre-embedding process. At this time, by rotating the adjusting bolt 1114, the locking rod 1108 is moved, so that the distance between the locking rod 1108 and the center of the worm gear 1103 can be adjusted. When the embedded column 1116 is far away from the center of the locking rod 1108, the locking rod 1108 can be adjusted outward so that the locking rod 1108 can be connected to the embedded column 1116.

[0030] In a preferred embodiment: a bottom limiting piece 1111 is installed on the inner wall of the adjusting base 1107, a top limiting piece 1112 is installed on the top of the bottom limiting piece 1111, the top limiting piece 1112 is slidably connected to the adjusting base 1107, and the bottom limiting piece 1111 and the top limiting piece 1112 are connected by a fixing bolt 1113.

[0031] In the above structure, the top limiting plate 1112 and the bottom limiting plate 1111 limit the adjusting bolt 1114, allowing the adjusting bolt 1114 to rotate between the top limiting plate 1112 and the bottom limiting plate 1111. Therefore, by rotating the adjusting bolt 1114, the locking rod 1108 can move in the adjusting base 1107. By unscrewing the fixing bolt 1113 and then removing the top limiting plate 1112 from the adjusting base 1107, the adjusting bolt 1114 can be separated from the bottom limiting plate 1111.

[0032] In a preferred embodiment: a circular hole 1204 is provided on the outer wall of the vertical support steel 1201, a connecting rod 1205 is installed on the inner wall of the circular hole 1204, a bottom support frame 1206 is movably connected to the connecting rod 1205, and a bottom roller 1207 is installed on the inner wall of the bottom support frame 1206.

[0033] In the above structure, the inclined support steel 1101 rests on the bottom roller 1207 through the setting of the bottom roller 1207. Finally, the inclined support steel 1101 continues to move in the direction of the vertical support steel 1201, so that the inclined support steel 1101 drives the bottom roller 1207 to roll. The rolling of the bottom roller 1207 can reduce the moving resistance of the inclined support steel 1101.

[0034] In a preferred embodiment: the inner wall of the vertical support steel 1201 is provided with a groove 1203, the inner wall of the groove 1203 is slidably connected to a limiting slide plate 1211, the inner wall of the limiting slide plate 1211 is installed with a connecting shaft 1212, the top support frame 1213 is movably connected to the connecting shaft 1212, and the inner wall of the top support frame 1213 is installed with a top roller 1214.

[0035] In the above structure, the limiting slide plate 1211 and the slide groove 1203 are configured, and the inner wall of the limiting slide plate 1211 is equipped with a connecting shaft 1212, so that the top support frame 1213 and the limiting slide plate 1211 can move up and down in the slide groove 1203, so that the distance between the bottom support frame 1206 and the top support frame 1213 can be adjusted. When the inclined support steel 1101 is installed, the distance between the top support frame 1213 and the bottom support frame 1206 is larger than the distance between the top support frame 1213 and the bottom support frame 1206 after installation. When the inclined support steel 1101 is fully in place in the support hole 6, the top support frame 1213 is moved downward, so that the top roller 1214 on the top support frame 1213 contacts the inclined support steel 1101. At this time, the inclined support steel 1101 cannot continue to move forward, so it can play a supporting role.

[0036] In a preferred embodiment: an adjusting plate 1209 is installed on the outer wall of the limiting slide plate 1211, a handle 1210 is installed on the outer wall of the adjusting plate 1209, and a through groove 1208 is opened on the outer wall of the vertical support steel 1201, and the adjusting plate 1209 is slidably connected to the through groove 1208.

[0037] In the above structure, by setting the adjusting plate 1209, during construction, two construction workers can move the adjusting plate 1209 up and down at the same time, so that the adjusting plate 1209 can drive the connecting shaft 1212 to move. By setting the through slot 1208, since the adjusting plate 1209 is connected to the limiting slide plate 1211 and the connecting shaft 1212, the adjusting plate 1209 needs to pass through the through slot 1208.

[0038] In a preferred embodiment: both the adjusting plate 1209 and the outer wall of the vertical support steel 1201 are provided with fixing holes 1215, and the inner wall of the fixing holes 1215 is threaded with positioning bolts 1216.

[0039] In the above structure, by using the fixing hole 1215 and the positioning bolt 1216 together, when the adjusting plate 1209 is moved to the appropriate position, the positioning bolt 1216 is screwed into the fixing hole 1215 on the adjusting plate 1209 and the fixing hole 1215 on the vertical support steel 1201, so that the adjusting plate 1209 cannot move downward or upward. Therefore, the top support frame 1213 and the bottom support frame 1206 can block the inclined support steel 1101, so that the inclined support steel 1101 cannot continue to move forward.

[0040] In a preferred embodiment, a plurality of fixing holes 1215 are provided, and the plurality of fixing holes 1215 are evenly distributed on the vertical support steel 1201.

[0041] In the above structure, the setting of several fixing holes 1215 allows the fixing holes 1215 on the adjusting plate 1209 to flexibly correspond to the fixing holes 1215 on the vertical support steel 1201, so that the adjusting plate 1209 can better contact the inclined support steel 1101 when adjusting.

[0042] Working principle: During use, holes are drilled in the soil body 2, and then vertical piles 3 are poured into the holes. After the vertical piles 3 are poured, a crown beam 4 and a support beam 5 are poured on top of the vertical piles 3. Support holes 6 are reserved on the support beam 5. When pouring the support beam 5, the pre-embedded column 1116 is pre-embedded in the support beam 5. Then, the soil body 2 is excavated to expose part of the vertical piles 3. Then, a support base 7 is poured on the excavated soil body 2. Then, the vertical support steel 1201 is placed in the support base 7, and the inclined support steel 1101 is inserted from the support hole 6. The inclined support steel 1101 first contacts the bottom roller 1207, at which point the adjusting plate 1209 is not fixed by the positioning bolt 1216. After the limiting plate 1102 is fully in contact with the support beam 5, the locking nut 1105 and the worm gear 1104 are rotated by an electric wrench. When the worm gear 1104 rotates, it drives the worm wheel 1103 to rotate. When the worm wheel 1103 rotates, it drives the adjusting base 1107 and the locking rod 1108 to rotate. Subsequently, the locking groove 1109 on the locking rod 1108 will engage with the pre-locking groove 1109. When the embedded column 1116 comes into contact, the locking rod 1108 is blocked by the blocking plate 1117. The adjusting plate 1209, the connecting shaft 1212, and the top roller 1214 move downwards due to their own weight, causing the top roller 1214 to come into contact with the inclined support steel 1101. Then, the fixing holes 1215 on the adjusting plate 1209 are aligned with the fixing holes 1215 on the vertical support steel 1201, and the positioning bolts 1216 are tightened. The inclined support steel 1101 is blocked by the bottom support frame 1206 and the top support frame 1213. The oblique support steel 1101 is blocked from moving forward, so the vertical pile 3 can be supported. When disassembly is required, the positioning bolt 1216 is removed to allow the top support frame 1213 to move. Then, the worm gear 1104 is rotated, causing the worm wheel 1103 to rotate and drive the locking rod 1108 to rotate. The locking rod 1108 is separated from the embedded column 1116. At this time, the limit plate 1102 and the oblique support steel 1101 can be pulled out from the support hole 6, and then the vertical support steel 1201 can be pulled out from the support base 7.
