[0002] With the development of urban rail transit, when shield construction passes through foundation pit retaining structures, it is difficult for shield machines to cut reinforced concrete, and the cutters are easily damaged and the cutter disc is easily jammed with steel bars. Therefore, a combined retaining form of underground continuous walls combined with cement-soil mixing walls and extra-long H-steels is adopted. The H-steels are removed after the underground structure is rebuilt.

[0003] However, the H-shaped steel in this enclosure form is very long and has a large aspect ratio due to the ultra-deep cement-soil mixing wall.

[0018] A construction method for a device for synchronously positioning and inserting multiple steel sections, the process of which comprises the following steps:

[0019] S1: Positioning of the positioning frame: First, according to the design requirements, use measuring instruments to perform precise line-laying operations to accurately determine the specific position of the H-beam insertion. After determining the position, place the positioning frame mechanism as a whole stably at the corresponding position, and use the flatness adjustment bolts to firmly position and connect the four corners of the positioning frame mechanism to the ground to ensure that the positioning frame mechanism will not be displaced during the subsequent construction process;

[0020] S2: Frame leveling: After the positioning frame mechanism is placed, a steel gasket is placed at its bottom. The frame is initially leveled by adjusting the thickness of the steel gasket.

[0024] S6: Frame dismantling and transfer: After the H-beam insertion operation is completed, use the vertical channel steel as a supporting tool and operate with the nut to pull the frame out from the completed construction position.

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] The following describes an embodiment of the present invention based on its overall structure.

[0040] Embodiment 1

[0041] A device for synchronously positioning and inserting multiple steel sections, such as Figure 1-11 As shown, the positioning frame mechanism 1 is included. The positioning frame mechanism 1 is the basic part of the whole device, including a positioning frame 101, a flatness adjustment bolt 102, an adjustment nut 103, a steel gasket 104, a first connection groove 105 and a counterweight 106. The flatness adjustment bolts 102 at the four corners of the positioning frame 101 penetrate the frame, and the adjustment nuts 103 cooperate with them to accurately adjust the horizontal elevation of the positioning frame 101;

[0042] In actual operation, by rotating the adjusting nut 103, the flatness adjusting bolt 102 is raised or lowered, so that the positioning frame 101 reaches the horizontality required by the design, and the error is controlled within a very small range;

[0043] The steel gasket 104 is placed at the bottom of the four sets of flatness adjustment bolts 102 and in contact with the ground, which can further adjust the flatness of the frame and disperse the pressure. The counterweight blocks 106 are placed on both sides of the top of the positioning frame 101 to enhance the stability of the frame during construction and prevent it from shaking or tilting;

[0044] The first connection groove 105 cooperates with multiple groups of vertical channel steels 3 and is fixedly connected by welding to ensure a stable connection between the components;

[0045] The first limit frame mechanism 2 is located at the top of the positioning frame mechanism 1, and includes a first limit frame 201 and a second connection groove 202, and the second connection groove 202 is used for welding and connecting with the vertical channel steel 3. The second limit frame mechanism 4 is located above the first limit frame mechanism 2, and includes a second limit frame 401. The first limit frame 201 and the second limit frame 401 are provided with a steel insertion cavity 8 on both sides to provide space for the placement of the H-shaped steel 7;

[0046] A longitudinal positioning mechanism 5 is provided at the middle position of both sides inside each steel insertion cavity 8. The longitudinal positioning mechanism 5 is composed of a fixing frame 501, a connecting through hole 502, a positioning bolt 503 and a positioning steel plate 504. Each set of longitudinal positioning mechanisms 5 has two sets of fixing frames 501 fixed on both sides inside the steel insertion cavity 8. Both sides of the positioning steel plate 504 are connected to the fixing frame 501 by the positioning bolts 503. The connecting through holes 502 inside the fixing frame 501 cooperate with the positioning bolts 503.

[0047] In actual operation, according to the designed longitudinal position requirements of the H-beam 7 combination plane, the positioning steel plate 504 can be accurately moved to a suitable position by rotating the positioning bolt 503, thereby determining the accurate longitudinal position of the H-beam 7 in the plane;

[0048] When the H-shaped steel 7 needs to be positioned longitudinally at a specific position, the positioning bolts 503 are precisely adjusted so that the distance between the positioning steel plates 504 meets the width requirement of the H-shaped steel 7, ensuring that the H-shaped steel 7 is neatly arranged longitudinally;

[0049] The transverse positioning mechanism 6 is used to control the transverse position of the H-shaped steel 7, and includes a fixed frame 601, a telescopic frame 602, a pulley 603, a fastening bolt 604, a fastening nut 605, a sliding hole 606, a fixing screw head 607 and a limiting sliding groove 608. The telescopic frame 602 is located inside the fixed frame 601 for sliding connection, and the pulley 603 is located at the end of the telescopic frame 602 for rotation connection, and its surface is in contact with the H-shaped steel 7;

[0050] The fastening bolt 604 at one end of the telescopic frame 602 passes through the sliding hole 606 at one end of the fixed frame 601 and is fixed by the fastening nut 605. The extension length of the telescopic frame 602 can be adjusted, thereby adjusting the position of the pulley 603. The fixing screw head 607 at the other end of the telescopic frame 602 slides in the limiting slide groove 608 at the other end of the fixed frame 601 to ensure the stability of the movement of the telescopic frame 602. By adjusting the position of the pulley 603, the horizontal position of the H-shaped steel 7 in the plane can be fixed, which cooperates with the longitudinal positioning to accurately define the insertion position and space of the H-shaped steel 7.

[0051] First, the construction personnel use the total station and other measuring instruments to perform precise line laying operations according to the design requirements, accurately determine the specific position of the H-shaped steel 7, and after determining the position, place the positioning frame mechanism 1 as a whole stably at the corresponding position, and then use the flatness adjustment bolts 102 to firmly position and connect the four corners of the positioning frame mechanism 1 to the ground;

[0052] For example, in a subway foundation pit construction project, the surveyor accurately marks the positions of the four corners of the positioning frame mechanism 1 on the ground according to the design drawings, with the error controlled at the millimeter level. When placing the positioning frame mechanism 1, ensure that it is completely consistent with the marked position, and then tighten the flatness adjustment bolt 102 to make it tightly connected to the ground to prevent displacement during the subsequent construction process;

[0053] After the positioning frame mechanism 1 is placed, a steel gasket 104 is placed at the bottom thereof. The construction personnel use a level to detect the flatness of the frame, and adjust the thickness of the steel gasket 104 according to the detection result to preliminarily level the frame. Then, the flatness adjustment bolt 102 is carefully adjusted to finely adjust the horizontal elevation of the frame.

[0054] If it is found that a corner of the frame is too low, the thickness of the steel gasket 104 under the flatness adjustment bolt 102 at the corner can be increased, or the flatness adjustment bolt 102 can be rotated to raise the corner until the horizontal elevation of the frame reaches the design requirement, so as to ensure that the H-shaped steel 7 can maintain good flatness when inserted. At the same time, a counterweight block 106 is placed on the frame. According to the size of the frame and the construction environment, a counterweight block 106 of appropriate weight is selected and placed on both sides of the top of the positioning frame 101 to enhance the stability of the frame during the entire construction process and prevent the frame from shaking or tilting when subjected to external forces.

[0055] The longitudinal positioning is adjusted by using the positioning steel plates 504 and the positioning bolts 503 on the first limiting frame mechanism 2 and the second limiting frame mechanism 4. The construction personnel rotate the positioning bolts 503 using tools such as wrenches according to the longitudinal position requirements of the combined plane of the designed H-shaped steel 7.

[0056] For example, in the insertion and placement construction of a group of three H-shaped steels 7, if the design requires that the longitudinal spacing of the three H-shaped steels 7 be a certain value, the construction personnel rotate the positioning bolts 503 to accurately move the positioning steel plate 504 to a suitable position, thereby ensuring the accurate longitudinal position of the three H-shaped steels 7 in the plane, so that they can be placed according to the predetermined position in the subsequent insertion and placement process;

[0057] According to the preset horizontal position of the H-shaped steel 7 plane, the construction personnel adjust the position of the pulley 603 by loosening the fastening nut 605, moving the telescopic frame 602 to adjust the position of the pulley 603, and then tightening the fastening nut 605 to fix it;

[0058] For example, when the H-beam 7 needs to be positioned at a certain position horizontally, the pulley 603 is adjusted to a position corresponding to the position. The adjustment of the position of the pulley 603 can effectively fix the horizontal position of the H-beam 7 in the plane, and cooperate with the longitudinal positioning to accurately define the insertion position and space of the H-beam 7, so that the H-beam 7 can reach the specified position accurately when inserted, ensuring that the accuracy of the actual construction is controlled within the allowable range;

[0059] After completing the above positioning operation, the H-beam 7 is lowered and inserted through the pulleys 603 of the first and second layers. The H-beam 7 is lifted by a crane or other lifting machinery, and then slowly lowered. The rolling effect of the pulley 603 is utilized to smoothly lower the H-beam 7 and insert it into the designated position. During this process, the commanding personnel always pay attention to the lowering of the H-beam 7, and keep in close contact with the crane driver through communication equipment such as walkie-talkies to ensure that it is lowered steadily and vertically to avoid abnormal situations such as collision with surrounding structures.

[0060] For example, in the construction of a station foundation pit, when the H-shaped steel 7 is lowered, the command personnel stand in a suitable position, observe the distance between the H-shaped steel 7 and the surrounding soil, installed steel, etc., and promptly command the crane to adjust the lowering speed and direction to ensure that the H-shaped steel 7 is safely and accurately inserted into the cement soil;

[0061] When the H-shaped steel 7 is inserted, the vertical channel steel 3 is used as a supporting tool and the nut is used to pull the frame out from the completed construction position. The construction personnel first install the nut at the corresponding position of the vertical channel steel 3, and then use the tool to rotate the nut to make the vertical channel steel 3 generate an upward force to slowly pull out the frame.

[0062] During the dismantling process, strictly follow the operating procedures, pay attention to the standardization and safety of the operation, avoid damage to the completed engineering structure, and after the frame is dismantled, use the lifting equipment to quickly move it to the next group of positions where H-shaped steel 7 needs to be inserted and placed, and prepare for the next round of construction operations, thereby improving the efficiency of the entire construction process;

[0063] For example, in the construction of a tunnel foundation pit, after one set of H-shaped steel 7 is inserted and placed, the construction workers quickly dismantle the frame and lift it to the adjacent construction section to insert and place the next set of H-shaped steel 7, thereby reducing the construction interval time.

[0064] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
