Description

Technical Field

[0001] The invention belongs to the field of deep foundation pit support, and particularly relates to a deep foundation pit support device and an installation method thereof. Background Art

[0002] A deep foundation pit refers to a project with an excavation depth of more than 5 meters (including 5 meters), or a project with a depth of less than 5 meters but with particularly complex geological conditions, surrounding environment and underground pipelines. The foundation pit project is to excavate an underground space from the ground downwards. In the actual operation process, the top elevation of the steel lattice columns in the deep foundation pit is often designed to be below the ground. The construction workers cannot see the installation posture, resulting in deviations in the direction, angle and elevation of the steel lattice columns during installation. This deviation will affect the stress of the concrete support beam above. By inserting "guide columns" into the lattice columns, the lattice columns are artificially guided 50 cm above the ground. Construction technicians can control the elevation, direction and angle of the lattice columns through the "guide columns". The guide columns are mainly set to support the steel lattice columns so that they can be moved up to the ground, so that construction personnel can observe the direction, angle, elevation and other deviations of the parts that were previously invisible below the ground. After adjusting the posture and position of the steel lattice columns through the "guide columns", it can be ensured that the concrete support beams arranged on the steel lattice columns in the subsequent stage are accurately stressed according to the design intention. Therefore, the most important thing is often to support and adjust the posture and position of multiple groups of steel lattice columns in the deep foundation pit to ensure that the multiple groups of steel lattice columns can be lifted so that the steel lattice columns can be lifted to more than 50 cm from the ground, so that the direction and angle of the steel lattice columns located in the underground part will not be offset, while ensuring the stress condition of the concrete support beams and the accuracy of the elevation.

[0003] When the existing deep foundation pit support structure is used, the deep foundation pit support structure is often placed in the deep foundation pit first, connected to the steel lattice columns through the deep foundation pit support structure, and use guide columns to contact and support the multiple groups of steel lattice columns in the deep foundation pit in two opposite directions to maintain the stability of the multiple groups of steel lattice columns in the deep foundation pit and the accuracy of installation. After the construction of the steel lattice columns is completed, the guide columns can be removed to achieve multiple uses of the guide columns. However, when the steel lattice columns of the deep foundation pit support structure are supporting, they can often only adjust the side surfaces of the deep foundation pit steel lattice columns in two opposite directions, but cannot simultaneously support the side surfaces of the deep foundation pit steel lattice columns in two opposite directions and adjust the two directions perpendicular to the side surfaces in the two opposite directions. Improvement is urgently needed.

[0004] The present invention seeks to alleviate or at least mitigate such problems or deficiencies by providing new or otherwise improved deep excavation support. Summary of the Invention

[0070] S7. Driving the bottom drive member: When the three-way support member is in the second position, the trigger gear and the meshing gear are in contact with each other. When the three-way support member is in operation, the output end of the third drive motor generates output to force the meshing gear and the second connecting screw to operate and eject the interpenetrating member.

[0071] S8. Installation of the inserting member: install the inserting member at the bottom of the support frame, slide the inserting screw into the bottom support, and when the horizontal section of the second ball base is pushed and the horizontal section of the second ball base conflicts with the bonding plate, the inserting screw is used to be ejected from the bottom support, and the three-way support member and the bottom driving member are linked to complete the driving of the inserting member, so as to further reinforce the bottom of the deep foundation pit and complete the support and reinforcement operation of the deep foundation pit.

[0072] In general, the above technical solutions conceived by the present invention have the following beneficial effects compared with the prior art:

Guide posts can be installed on the three groups of press-fit connectors 58. It should be noted that the guide posts are known components in the prior art and will not be described in detail in the present invention.

[0099] Next, the structure and construction of the press-fit connector 58 will be further explained in more detail. The press-fit connector 58 includes a press-fit plate 581, which is detachably disposed at the end of the one-way extending arm 57 away from the arc-shaped support ring 56.

[0100] More specifically, when the press-fit connector 58 is used, the directional screw 583 is removably arranged in the adjustment groove 582, and the directional screw 583 is raised or lowered along the length direction of the adjustment groove 582 to adjust the insertion position of the directional screw 583.

[0101] In the embodiment, it should be noted that the guide pin is a known component in the prior art, and its length and diameter can be set according to different usage conditions. Of course, the length of the directional screw 583 should be set to match the length of the guide pin. In actual operation, the guide pin can be installed on the directional screw 583 by welding, riveting, or clamping.

[0102] When the guide post is too long and the diameter is too large, it can also be lifted to the directional screw 583 by means of a crane. Of course, at the tail end of the directional screw 583, an electromagnet adsorption device can be set, and power can be turned on in the electromagnet adsorption device at the tail end of the directional screw 583 to complete the adsorption of the guide post. Of course, the guide post can also be installed on the directional screw 583 by snapping, so that the guide post can be easily removed after use, so as to facilitate subsequent use. It should also be noted that the electromagnet adsorption device installed at the tail end of the directional screw 583 is a known component in the prior art, and will not be described in detail in the present invention. The present invention does not impose too many restrictions on the size of the guide post and the directional screw 583.

[0103] Next, a more specific structure and construction of the bottom driving member 6 as a whole is given for further explanation. The bottom driving member 6 includes a connecting plate 61, which is detachably arranged on the support frame 1, and a third machine frame 62 is detachably arranged on it; a second connecting screw rod 63, which is rotatably arranged in the third machine frame 62; a second ball base 64, which is slidably arranged in the third machine frame 62 and is passed through by the second connecting screw rod 63; a driving plate 65, which is detachably arranged on the second ball base 64 and extends toward the bottom of the support frame 1; a third coupling 66, which is detachably arranged at one end of the second connecting screw rod 63, and a short rod 67 is removably arranged therein, and the short rod 67 passes through the third machine frame 62; and a meshing gear 68, which is detachably arranged on one end of the third coupling 66 passing through the third machine frame 62;

[0104] Next, the overall operating principle of the bottom driving member 6 is further explained. When the three-way supporting member 5 is in the second position, the trigger gear 515 and the meshing gear 68 are in contact with each other. When the output end of the third driving motor 512 outputs, the meshing gear 68 and the second connecting screw 63 are forced to operate and the inserted member 7 is ejected.

[0105] In some embodiments, more specifically, the driving plate 65 is composed of a vertical section connected to the second ball base 64 and a horizontal section connected to the vertical section, and the horizontal section does not contact the interpenetrating member 7 when in the initial state.

[0106] Next, the insertion member 7 is given a more specific structure and construction as a whole for further explanation.

[0107] Next, the overall working principle of the insertion member 7 is further explained. When the horizontal section of the second ball base 64 is pushed and the horizontal section of the second ball base 64 conflicts with the bonding plate 74, it is used to push the insertion screw 72 out of the bottom support 71. When the second ball base 64 returns to its initial position, the spring 75 is compressed, so the spring 75 loses its elastic restriction and returns to its initial position. At the same time, it is restricted by the contact between the built-in limit block 73 and the bottom support 71, which can effectively prevent the insertion screw 72 from falling off from the bottom support 71.

Simultaneously, tighten the first locking nut 584 to mate with one side of the press-fit plate 581 and tighten the second locking nut 585 to mate with the other side of the press-fit plate 581. Finally, install the guide pin onto the directional screw 583.

[0115] S7.

When the three-way supporting member 5 is in operation, the output end of the third driving motor 512 is output to force the meshing gear 68 and the second connecting screw 63 to operate and eject the insertion member 7;

[0116] S8. Installation of the insertion member 7: Install the insertion member 7 at the bottom of the support frame 1, and slide the insertion screw 72 into the bottom support 71. When the horizontal section of the second ball base 64 is pushed and the horizontal section of the second ball base 64 conflicts with the bonding plate 74, the insertion screw 72 is pushed out from the bottom support 71, and can be driven by the three-way support member 5 and the bottom driving member 6 to further reinforce the bottom of the deep foundation pit, thereby completing the support and reinforcement operation of the deep foundation pit.

[0117] In summary, through the buried reinforcement component 4, the left collar 42 and the right collar 47 are respectively sleeved on the reinforcement rod 11, and the first limiting bolt 43 is screwed into the through-hole 12, so that the left collar 42 and the right collar 47 are positioned on the reinforcement rod 11, and the right extension rod 493 is inserted into the left extension rod 45, and the second limiting bolt 494 is inserted into the overlapping part of the first lock hole and the second lock hole to position the right extension rod 493 and the left extension rod 45, so that the left connecting arm 41, the right connecting arm 46, the right extension rod 493 and the right extension rod 495 form a built-in annular support area to complete the reinforcement between the multiple groups of reinforcement rods 11, and the multiple groups of left inclined plates 441 and the multiple groups of right inclined plates 491 are all stretched open, so that each of the two opposite groups of left inclined plates 4 41 and the deep foundation pit plane form a triangular support area, and at the same time, each opposite set of right inclined plates 491 and the deep foundation pit plane form a triangular support area, so as to strengthen the stability of the buried reinforcement component 4 as a whole and the deep foundation pit plane, and at the same time strengthen the stability between the multiple sets of reinforcing rods 11, through the arranged three-way support component 5, turn on the switch of the third drive motor 512, so that the output end of the third drive motor 512 outputs to drive the drive gear plate 59 to rotate, so as to drive the three sets of one-way extension rods 54 to pass through the through-hole groove of the one-way extension arm 53, so as to push the three sets of press-fit connectors 58 to be ejected, and before this, a guide column is installed on the press-fit connector 58, and it can make the press The connecting parts 58 extend from three different directions together with the guide columns to penetrate into the multiple groups of steel lattice columns in the deep foundation pit, so as to complete the reinforcement and posture and position adjustment of the multiple groups of steel lattice columns in the deep foundation pit by the support frame 1 as a whole. At the same time, it can cooperate with the use of the buried reinforcement component 4 to reinforce the support frame 1 as a whole from the plane of the deep foundation pit, and at the same time, it can be reinforced from three different directions at the top of the support frame 1. At the same time, through the arranged bottom driving component 6, during the operation of the three-way support component 5, the bottom driving component 6 can be triggered to force the insertion component 7 to operate.
