Description

Technical Field

[0001] The utility model belongs to the technical field of foundation pit support in civil engineering, and particularly relates to an assembled steel waist beam device for anchor cables. Background Art

[0002] In recent years, with the large-scale development of urban underground space, a large number of foundation pit projects have emerged. Prestressed anchor cables are widely used in temporary foundation pit support in combination with vertical retaining piles due to their simple construction, good anchoring effect, and ability to provide open working space within the foundation pit. The anchor cable structure in foundation pit support generally needs to be set at a horizontal downward angle of 15° to 30° to ensure anchor grouting and bearing performance. At this time, the tensioning section of the anchor cable extending out from the side wall of the foundation pit retaining pile must maintain the same tensioning angle to avoid bending and damage to the anchor cable steel strand, which would affect the anchor cable bearing performance. At the same time, the prestress of the anchor cable must be evenly transferred to the retaining piles on both sides to effectively resist the soil pressure on the foundation pit side wall. However, due to the deviation in the construction position of the retaining piles, it is often difficult to ensure the absolute straightness of the foundation pit side wall, which in turn affects the uniform transmission of the anchor cable prestress. To address the above-mentioned issues, a reinforced concrete waist beam structure can be cast on the outside of the retaining piles, and PVC pipes or steel pipes with the same horizontal inclination angle as the anchor cables can be pre-buried in the waist beam concrete structure to ensure the straight tensioning of the anchor cables on the outside of the waist beam and the effective transmission of prestress. However, due to the large size and heavy weight of the reinforced concrete waist beam structure and the long construction and maintenance period, the progress of foundation pit support construction is seriously restricted. In addition, when backfilling the fertilizer trough of the foundation pit in the later stage, it is difficult to effectively backfill and compact due to the limitation of the concrete waist beam. As a temporary project, in order to save construction time, a composite steel waist beam structure is also widely used. However, the steel waist beam cannot adapt to the unevenness of the retaining piles on the side wall of the foundation pit. It is often the case that the steel waist beam cannot effectively fit the retaining piles after installation. In addition, due to the limitations of on-site construction conditions, it is difficult to achieve the same horizontal inclination angle as the anchor cables during installation. This causes problems such as bending of the anchor cable steel strands and uneven prestress transmission. In serious cases, it affects the safety and stability of the foundation pit.

[0033] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0034] like Figures 1 to 7 As shown, the utility model includes a fixing mechanism 4 installed on the guard pile 2, a telescopic mechanism 6 arranged on the fixing mechanism 4, and a combined steel mechanism 7 arranged on the outside of the multiple telescopic mechanisms 6, and a force transmission mechanism 8 for transmitting the prestress of the anchor cable steel strand 3 to the combined steel mechanism 7 is arranged on the outside of the combined steel mechanism 7; the telescopic mechanism 6 includes a bolt 6-2, and a directional plate socket 6-6 connected to the fixing mechanism 4 is opened on the bolt 6-2, and an adjusting nut 6-1 is threadedly connected to the outside of the bolt 6-2, and a plurality of rotating sockets 6-5 are opened on the side wall of the adjusting nut 6-1, and an inclined iron pad 6-3 is fixedly welded to the end of the bolt 6-2 away from the fixing mechanism 4, and the inclined surface of the inclined iron pad 6-3 is welded to the steel support plate 6-4.

[0035] In this embodiment, the inclined iron pad 6-3 is a steel pad of unequal thickness, the inclination angle of the inclined surface of the inclined iron pad 6-3 is consistent with the horizontal inclination angle of the anchor cable, the inclined iron pad 6-3 is connected to the bolt 6-2 by welding, and the steel support plate 6-4 is a steel plate of unequal thickness, the thick surface of the steel support plate 6-4 is welded to the inclined surface of the inclined iron pad 6-3, and the upper surface of the steel support plate 6-4 is perpendicular to the inclined surface of the inclined iron pad 6-3.

[0036] It should be noted that the telescopic mechanism 6 is used to adjust the distance between the combined steel structure 7 and the retaining pile 2, ensuring that the retaining pile 2 is in close contact with the combined steel structure 7, thereby effectively transmitting the prestressed anchor cable; the adjusting nut 6-1 is connected to the bolt 6-2 by a thread, and a plurality of rotating sockets 6-5 are provided on the outside of the adjusting nut 6-1, through which steel bars, crowbars, etc. can be inserted to rotate the adjusting nut 6-1, and a directional plate socket 6-6 is provided in the middle of the bolt along the axial direction. The directional plate socket 6-6 is a rectangular slot, which is mainly used to insert the directional plate 4-4 in the fixing mechanism 4, and the steel support plate 6-4 provides a mounting bracket for installing the waist beam combined steel structure 7.

[0037] In this embodiment, the fixing mechanism 4 includes an arc-shaped pad 4-1 having the same curvature as the outer curvature of the retaining pile 2. The arc-shaped pad 4-1 is fixedly connected to the retaining pile 2 by an expansion bolt 5. Pads 4-2 are welded on both sides of the arc-shaped pad 4-1. Rectangular pads 4-3 are welded on the tops of the two pads 4-2. A directional plate 4-4 that cooperates with the directional plate socket 6-6 is fixed in the middle of the rectangular pad 4-3.

[0038] In this embodiment, the directional plate 4-4 is a steel plate of equal thickness. The directional plate 4-4 is vertically fixed in the middle of the rectangular pad 4-3. The size of the directional plate 4-4 is smaller than the directional plate socket 6-6 in the bolt 6-2 in the telescopic mechanism 6, and is used for on-site positioning and installation of the telescopic mechanism 6.

[0039] It should be noted that the fixing mechanism 4 is used to install and fix the entire steel waist beam structure on the retaining piles 2 on both sides of the anchor cable; the arc-shaped pad 4-1, pad 4-2, and rectangular pad 4-3 are all made of steel structures, and the directional plate 4-4 is smaller than the directional plate socket 6-6 in the bolt 6-2 in the telescopic mechanism 6, and is used for on-site positioning and installation of the telescopic mechanism 6, and can ensure that when the adjusting nut 6-1 rotates, the bolt 6-2 and the inclined iron pad 6-3 only move perpendicular to the supporting surface of the retaining pile 2, and will not rotate with the adjusting nut 6-1, thereby better ensuring the standardization and convenience of the steel waist beam installation.

[0040] In this embodiment, the combined steel structure 7 includes two parallel arranged steel sections 7-1, the tops of the two parallel arranged steel sections 7-1 are connected by multiple top gussets 7-2, and the bottoms of the two parallel arranged steel sections 7-1 are connected by multiple bottom gussets 7-3. There is a gap between the two parallel arranged steel sections 7-1 for the anchor cable steel strand 3 to pass through, and the steel support plate 6-4 extends into the gap.

[0041] It should be noted that the top gusset plate 7-2 and the bottom gusset plate 7-3 are steel plates, which are welded to the upper flange and lower flange of the steel section 7-1 respectively according to the overall force requirements, and the double-piece steel section is welded into a whole.

[0042] In this embodiment, the force transmission mechanism 8 includes an anchor head pressure plate 8-1 and an anchor 8-2 arranged on the anchor head pressure plate 8-1. The anchor 8-2 is provided with a through hole for the anchor cable steel strand 3 to pass through. The anchor 8-2 is provided with a clip 8-3 for tensioning and locking the anchor cable steel strand 3. The upper end of the anchor head pressure plate 8-1 is provided with a hook matching the upper edge of the combined steel structure 1. The anchor head pressure plate 8-1 is connected to the combined steel structure 7 through the hook to prevent the anchor head pressure plate 8-1 from moving downward during the installation of the waist beam and the tensioning of the anchor cable steel strand 3.

[0043] When the utility model is used, the following steps are included:

[0044] Step 1: Determine the installation position of the steel waist beam and construct the anchor cable: When the foundation pit is excavated to 0.5m to 1.0m below the designed installation height of the steel waist beam, spray the concrete surface layer 9 on the side wall of the excavated foundation pit in time, and construct the prestressed anchor cables between the piles according to the design requirements. During the construction process, ensure that the anchor cable hole elevation is consistent, and the height error is no more than 5cm. After the anchor cable construction is completed, determine the installation position of the waist beam according to the anchor cable hole elevation; and clean the concrete surface layer within the corresponding height range of the retaining pile 2;

[0045] Step 2: Install the assembled steel waist beam fixing mechanism. The process is as follows:

[0046] Step 201: Determine the installation position of the arc-shaped pad 4-1 on the cleaned retaining pile 2 so that the middle of the arc-shaped pad 4-1 is slightly higher than the anchor hole, and install the expansion screw 5 at the corresponding position. The tops of multiple retaining piles 2 are connected by the crown beam 1.

[0047] Step 202: Effectively connect the arc-shaped pad 4-1 with the expansion screw 5, weld the pad 4-2 to the rectangular pad 4-3, and then weld them to the arc-shaped pad 4-1. During the welding process, ensure that the rectangular pads 4-3 are vertical, parallel to each other, and the height difference is no more than 2 cm. Then, use a level to determine the welding height of the oriented plate 4-4 and mark it on the rectangular pad 4-3.

[0048] Step 203: Weld the oriented plates 4-4 onto the rectangular pad 4-3 according to the markings, so that all oriented plates are at the same height and in the middle of the rectangular pad 4-3;

[0049] Step 3: Install the assembled steel waist beam telescopic mechanism: Weld the inclined iron plate 6-3, bolt 6-2, and steel support plate 6-4 into a whole in advance in the factory, tighten the adjusting nut 6-1 and bolt 6-2 until they are completely fitted, install the assembled telescopic mechanism 6 on the directional plate 4-4 through the directional plate socket 6-6 at the bottom of the bolt 6-2, and make the inclined surface of the inclined iron plate 6-3 uniformly upward to complete the installation of the telescopic mechanism 6;

[0050] Step 4: Install the assembled steel waist beam combined steel structure. The process is as follows:

[0051] Step 401: Place two I-beams in parallel with a 5 cm gap between them. Weld them together into a single piece using the top gusset plate 7-2 and the bottom gusset plate 7-3. During the welding process, the spacing between the I-beam flanges should be kept consistent. A gap should be left for the steel support plate 6-6 and the anchor cable strand 3 to pass through, based on the spacing between the retaining piles 2 and the width of the steel support plate 6-6.

[0052] Step 402: Use the hoisting equipment to lift the pre-processed combined steel structure 7. During the lowering process, adjust the steel support plate 6-6 slowly to insert it into the gap reserved between the two I-beams. After the combined steel structure 7 and the inclined iron pad 6-3 are completely in contact, place sleepers under the combined steel structure 7.

[0053] Step 403: Pass the steel strands of the anchor cable tensioning section through the reserved gap to complete the installation of the combined steel structure 7;

[0054] Step 5: Adjust the telescopic mechanism: After the combined steel structure is installed, the adjusting nuts 6-1 and bolts 6-2 in all telescopic mechanisms 6 are in full contact with each other. According to the construction deviation of the retaining pile 2, insert a crowbar into the adjusting nut socket 6-6 and rotate the adjusting nut 6-1 until the inclined surfaces of all the inclined iron pads 6-3 are in contact with the steel 7-1, ensuring that the waist beam effectively transmits force to all the retaining piles 2.

[0055] Step 6. Anchor cable tensioning and locking: At the exposed position of the anchor cable steel strand 3 outside the combined steel structure 7, install the anchor head pressure plate 8-1 and the anchor 8-2 in sequence. The anchor cable steel strand 3 passes through the holes of the anchor head pressure plate 8-1 and the anchor 8-2 in sequence, and install the clip 8-3 in the hole of the anchor 8-2. Use the jack to tension and lock the anchor cable steel strand 3 in sequence. After all the anchor cable steel strands 3 are tensioned and the test is completed, take out the sleepers under the combined steel structure 7, and install the prefabricated steel waist beams at other positions in sequence.

[0056] In this embodiment, the force transmission mechanism 8 is used to transmit the prestress of the anchor cable to the combined steel mechanism 7. The combined steel mechanism 7 further effectively transmits the prestress to the retaining piles 2 on the left and right sides of the anchor cable through the telescopic mechanism 6 and the fixing mechanism 4, providing the pile body fulcrum force in the anchor-pull foundation pit support structure, ensuring the safety of the foundation pit support.

[0057] In this embodiment, the width of the anchor head pressure plate 8-1 should be 20 cm and the thickness should be 2 cm; the inclined surface of the inclined iron pad 6-3 should not be less than the width of the lower flange of the combined steel structure 7, and the width should not be less than the diameter of the bolt 6-2; the outer diameter of the adjusting nut 6-1 should be 40 to 50 cm, the thickness should not be less than 8 cm, and the length should not be less than 20 cm; the length of the directional plate 4-4 is adjusted according to the length of the bolt 6-2, and the cross-sectional size should be 30 cm × 10 cm; the size of the rectangular pad 4-3 should not be less than 50 cm × 60 cm, and the thickness should be 2 cm; the top and bottom plates 7-2 and 7-3 should be 15 cm in length, 5 cm in width, and 1 cm in thickness; the steel support plate 6-4 is a steel plate of unequal thickness, the length should be greater than the leg length of the combined steel structure 7, the width should be the same as the width of the inclined iron pad 6-3, and the maximum thickness should not be greater than the spacing of 5 cm between the medium steel 7-1 of the combined steel structure 7.

[0058] In this embodiment, the anchor head pressure plate 8-1 has an arc-shaped hook on its upper part. The length of the anchor head pressure plate 8-1 is consistent with the width of the top of the combined steel structure 7, and the curvature of the hook is consistent with the size of the upper flange of the steel 7-1. This allows the anchor head pressure plate 8-1 to be hung on the combined steel 7, preventing the anchor head pressure plate 8-1 from moving downward during the installation of the waist beam and the tensioning of the anchor cable.

[0059] In this embodiment, the welding positions of the top gusset plate 7-2 and the bottom gusset plate 7-3 in the combined steel structure 7 should be consistent from top to bottom. At the same time, the gusset plate positions should be staggered with the anchor cable steel strand 3 and the steel support plate 6-4 as much as possible, so that the anchor cable steel strand 3 and the steel support plate 6-4 can pass through the middle gap of the combined steel structure 7 smoothly.

[0060] In this embodiment, the thread length of the bolt 6-2 and the adjusting nut 6-1 in the telescopic mechanism 6 is greater than 20 cm. When the construction position of the retaining pile 2 deviates, the distance between the inclined iron plate 6-3 and the retaining pile 2 can be changed by rotating the adjusting nut 6-1, so that all the retaining piles 2 are fitted with the waist beam combined steel structure 7, ensuring uniform and reliable force transmission of the anchor cable;

[0061] In this embodiment, the inclined iron plate 6-3 in the telescopic mechanism 6 is a variable thickness steel plate. The inclined iron plate should be processed and manufactured in advance in the factory. The thinnest thickness of the upper end steel plate is 1 cm, and the thickness of the lower end steel plate is determined according to the horizontal inclination angle of the anchor cable, so that the inclination angle of the inclined iron plate 6-3 is consistent with the horizontal inclination angle of the anchor cable, ensuring that the anchor cable steel strand 3 passes through the combined steel structure 7 straightly without bending or damage, thereby effectively transmitting the anchor cable prestress;

[0062] In this embodiment, the arc-shaped pad 4-1, pad 4-2 and rectangular pad 4-3 in the fixing mechanism 4 can be processed into a whole in advance in the factory according to the outer diameter of the retaining pile 2. On the one hand, this ensures the fit between the fixing mechanism 4 and the retaining pile 2, and on the other hand, it provides a vertical plane for the subsequent installation of the telescopic mechanism 6.

[0063] In this embodiment, when installing the directional boards in step 2, it should be noted that the directional boards on each retaining pile should be installed at the same height;

[0064] When installing the double-jointed composite steel structure in step 4, when the anchor cable strand passes through the middle gap of the composite steel structure, if it is found that the top or bottom gusset plate affects the straightness of the anchor cable strand, the composite steel structure can be moved left or right to ensure that the anchor cable strand is straight;

[0065] In step five, the anchor cable can be pre-tightened with a small force, and then the adjusting nut 6-1 is turned. After the adjustment is completed, the anchor cable is tensioned to the design locking force.

[0066] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
