Description

Technical Field

[0001] The present application relates to the technical field of foundation pit support, and in particular to a type of rapid deviation correction and reinforcement support pile for a building foundation pit. Background Art

[0002] The foundation pit is a pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Since the soil of some foundation pit walls is unstable and affected by groundwater, it is easy to affect the stability of the foundation pit. It is necessary to add support devices to prevent the foundation pit slope from collapsing;

[0003] For example, a patent number (CN210086259U) is a combined special-shaped support pile for rapid correction and reinforcement of a construction foundation pit, which includes a first straight plate, characterized in that: a plug is fixedly connected to the bottom surface of the first straight plate, a first straight block is fixedly connected to the top surface of the first straight plate, a driving mechanism is fixedly connected to the inner cavity of the first straight block, a first connecting block is fixedly connected to the right end of the driving mechanism, the first connecting block is rotatably connected to the second connecting block through a rotating shaft, a baffle is fixedly connected to the right side of the second connecting block, an adjusting mechanism is fixedly connected to the top of the first straight block, a second straight block is fixedly connected to the right end of the second straight block, and a sliding mechanism is fixedly connected to the right end of the sliding mechanism.

[0004] The main load-bearing structure in the above structure is on the plug. The plug is inserted into the soil and the driving mechanism and the sliding mechanism are adjusted to make the baffle and the plug tightly pressed against each other. However, since the plug is simply inserted into the soil, the stability is low. When the baffle is squeezed, the plug is easy to loosen or even fall over.

[0005] Therefore, it is necessary to design a kind of building foundation pit rapid deviation correction reinforcement support pile with better stability, which is not easy to loosen when squeezed by the side wall of the foundation pit and can better protect the foundation pit. Utility Model Content

[0006] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0007] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a construction foundation pit rapid deviation correction reinforcement support pile, including:

[0008] The support plate forms a support surface against the foundation pit wall;

[0009] substrate;

[0010] A telescopic assembly connecting the support plate and the base plate;

[0011] The plug-in assembly is fixedly arranged on the substrate, and the plug-in assembly includes:

[0012] An insertion rod is fixedly arranged on the bottom surface of the base plate;

[0013] A reinforcement rod, rotatably arranged on the insertion rod;

[0014] A push rod, movably disposed on the insertion rod;

[0015] Wherein, a hinged rod is rotatably arranged on the reinforcement rod, and the hinged rod is rotatably connected with the push rod, so that when the push rod moves, the hinged rod can drive the reinforcement rod to rotate.

[0016] During the working process, the supporting surface of the support plate is pressed against the foundation pit wall. Due to the setting of the plug-in assembly, the plug rod of the plug-in assembly can be inserted into the soil. By adjusting the length of the telescopic assembly, the support plate can be pressed against the foundation pit wall, so that the foundation pit wall can be quickly corrected and reinforced. Since a reinforcement rod and a push rod are set, when the push rod is pushed downward, the hinged rod can drive the reinforcement rod to rotate and extend. During the extension process of the reinforcement rod, it can be inserted into the soil around the plug rod, thereby further strengthening the connection between the plug rod and the soil and improving the stability of the support pile.

[0017] Furthermore, the top surface of the insertion rod is partially concave to form two hidden grooves, and a partition is formed between the two hidden grooves;

[0018] The reinforcement rod is arranged in the hidden groove and is rotatably arranged on the partition plate;

[0019] The top surface of the partition is partially concave to form a driving groove, and the push rod is movably arranged in the driving groove.

[0020] Furthermore, the side wall portion of the reinforcement rod is concave to form a connecting groove, and the hinge rod is rotatably arranged in the connecting groove.

[0021] Furthermore, a rotary cut portion with a triangular cross section is formed on the reinforcement rod.

[0022] Furthermore, the top surface of the base plate is partially concave and penetrates into the driving groove to form a through-slot corresponding to the driving groove, and the top end of the push rod is inserted through the through-slot;

[0023] A fixing plate is fixedly arranged on the top surface of the push rod, and corresponding threaded holes are formed on the fixing plate and the base plate so that the fixing plate and the base plate can be fixedly connected by bolts.

[0024] Furthermore, the telescopic assembly includes a first telescopic member and a second telescopic member, both ends of which are hinged to the supporting plate and the base plate respectively, and one end of the second telescopic member hinged to the supporting plate is arranged below the first telescopic member.

[0025] Furthermore, the first telescopic member includes a first rotating rod, a second rotating rod, and a connecting handle. The first rotating rod and the second rotating rod are respectively inserted into the connecting handle from both ends of the connecting handle and are threadedly connected to the connecting handle. The thread directions of the first rotating rod and the second rotating rod are opposite.

[0026] The first rotating rod is hinged to the supporting plate, and the second rotating rod is hinged to the base plate;

[0027] The structure of the second telescopic member is consistent with that of the first telescopic member.

[0028] Furthermore, a tapered portion is formed at the bottom of the insertion rod.

[0029] The beneficial effects of this application are:

[0030] 1. Since the main load-bearing component that contacts the support plate and the foundation pit wall is the plug rod, the plug rod needs to be able to be stably inserted into the soil to resist the pressure of the foundation pit wall on the support plate; by arranging a reinforcement rod on the plug rod, the push rod is pushed after the plug rod is inserted into the soil, and the reinforcement rod is expanded into the soil around the plug rod, the connection between the plug rod and the soil is further strengthened, so that the plug rod is not easy to loosen when subjected to thrust, thereby improving the stability of the support pile.

[0031] Second, the arrangement of the hidden groove and the driving groove enables the reinforcing rod and the push rod to be hidden inside the insertion rod, making it easier to insert the insertion rod into the soil.

[0032] 3. The arrangement of the first rotating rod, the second rotating rod and the connecting handle enables the supporting plate to be pressed against the foundation pit wall by rotating the connecting handle, thereby achieving rapid deviation correction. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0049] A kind of building foundation pit rapid deviation correction reinforcement support pile, including a support plate 1 and a base plate 2, a support surface 3 that contacts the foundation pit wall is formed on the support plate 1, and the support plate 1 and the base plate 2 are connected by a telescopic assembly 4; specifically, the telescopic assembly 4 includes a first telescopic member 5 and a second telescopic member 6, and the two ends of the first telescopic member 5 are respectively hinged to the support plate 1 and the base plate 2, and the first telescopic member 5 includes a first rotating rod 7, a first rotating rod 8, and a connecting handle 9. The first rotating rod 7 and the first rotating rod 8 are respectively inserted into the connecting handle 9 from the two ends of the connecting handle 9 and are threadedly connected to the connecting handle 9. The first rotating rod 7 and the first rotating rod 8 are respectively inserted into the connecting handle 9 from the two ends of the connecting handle 9 and are threadedly connected to the connecting handle 9. The threads on the rod 8 are in opposite directions, and the end of the first rotating rod 7 away from the connecting handle 9 is hinged to the supporting plate 1, and the end of the first rotating rod 8 away from the connecting handle 9 is hinged to the base plate 2; the structure and connection method of the second telescopic member 6 are consistent with the first telescopic member 5, the difference is that the end of the second telescopic member 6 hinged to the supporting plate 1 is arranged below the first telescopic member 5; during use, after the supporting surface 3 is pressed against the foundation pit wall, the position of the base plate 2 is fixed, and the connecting handle 9 is rotated to adjust the length of the first telescopic member 5 and the second telescopic member 6, and the supporting plate 1 is pressed against the foundation pit wall to achieve deviation correction and reinforcement of the foundation pit wall.

[0050] The fast deviation correction and reinforcement support pile for the building foundation pit also includes an insertion component 10, which is fixedly arranged on the bottom surface of the base plate 2 to fix the base plate 2, so that when the support plate 1 is squeezed by the foundation pit wall, the base plate 2 will not be displaced under the action of the first telescopic member 5 and the second telescopic member 6, causing unstable support;

[0051] Specifically, the plug assembly 10 includes an insertion rod 11, a reinforcement rod 12 and a push rod 13. The insertion rod 11 is fixedly connected to the base plate 2 by bolts. The insertion rod 11 is arranged on the bottom surface of the base plate 2. The top surface of the insertion rod 11 is partially concave and penetrates the two opposite side walls of the insertion rod 11 in the horizontal direction to form two hidden grooves 14. A partition 15 is formed between the two hidden grooves 14. The reinforcement rod 12 is arranged in the hidden groove 14 and is rotatably arranged on the partition 15. The top surface of the partition 15 is partially concave to form a driving groove 16. The push rod 13 is movably arranged in the driving groove 16 along the height direction of the insertion rod 11. The side wall portion of the reinforcement rod 12 is concave to form a connecting groove 17. A hinge rod 18 is arranged in the connecting groove 17. The hinge rod 18 is rotatably connected to the reinforcement rod 12. The end of the hinge rod 18 away from the reinforcement rod 12 is rotatably connected to the push rod 13. When the push rod 13 is moved downward, the reinforcement rod 12 can rotate under the drive of the hinge rod 18, so as to be extended into the hidden groove.

[0052] During use, after the supporting plate 1 is tightly attached to the foundation pit wall, the insertion rod 11 is inserted into the soil to fix the position of the base plate 2, and the push rod 13 is pushed downward. The hinged rod 18 drives the reinforcement rod 12 to rotate. After the reinforcement rod 12 rotates, the hidden groove is extended and screwed into the soil around the insertion rod 11, so that the connection between the insertion rod 11 and the soil is tighter, thereby improving the stability of the support pile.

[0053] More specifically, a rotary cut portion 19 with a triangular cross section is formed on the reinforcing rod 12, and the setting of the rotary cut portion 19 can reduce the resistance of the soil encountered by the reinforcing rod 12 when it is unfolded; a cone portion 20 is formed at the bottom of the insertion rod 11 to facilitate the insertion of the insertion rod 11 into the soil.

[0054] More specifically, the top surface portion of the base plate 2 is concave and penetrates into the driving groove 16 to form a through-slot 21 corresponding to the driving groove 16. The top end of the push rod 13 is inserted through the through-slot 21 and is arranged above the base plate 2. The top end of the push rod 13 is fixedly connected with a fixing plate 22. Corresponding threaded holes are formed on the fixing plate 22 and the base plate 2. When the push rod 13 is pushed downward until the reinforcement rod 12 is fully extended, the bottom surface of the fixing plate 22 fits with the top surface of the base plate 2. The fixing plate 22 and the base plate 2 can be threadedly connected by bolts to fix the position of the push rod 13, thereby fixing the reinforcement rod 12.

[0055] The specific working principle is as follows:

[0056] The supporting surface 3 of the supporting plate 1 is placed close to the foundation pit wall, and then the insertion rod 11 is inserted into the soil to fix the position of the base plate 2, and the push rod 13 is pushed downward. During the downward movement of the push rod 13, the hinged rod 18 drives the reinforcement rod 12 to rotate, and the reinforcement rod 12 is unfolded and screwed into the soil around the insertion rod 11 to reinforce the connection between the insertion rod 11 and the soil; the fixing plate 22 is fixedly connected to the base plate 2 with bolts to fix the reinforcement rod 12; the setting of the reinforcement rod 12 makes the connection between the insertion rod 11 and the soil more stable, and when the supporting plate 1 is squeezed by the foundation pit wall, the base plate 2 is not easy to loosen, thereby improving the stability of the supporting pile.

[0057] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
