[0038] like Figure 1-Figure 4 As shown, the construction platform assembly for excavating earth provided by the utility model includes: a construction platform 10 and a transfer mechanism 20. The construction platform 10 is used to place excavation equipment, and the transfer mechanism 20 cooperates with the construction platform 10 to enable the construction platform 10 to move to a preset position.
[0039] It should be noted that in the field of bridge construction, with the emergence of long-span bridges, there are more and more ultra-deep and ultra-large foundation pits, which brings a series of challenges to construction. For ultra-deep foundation pits, excavation equipment is required to excavate.
[0040] In the related art, the methods of vertical earth excavation include: 1) using larger excavation equipment for vertical earth excavation, but the construction cost is high and it is very uneconomical; 2) setting up a fixed excavation platform, placing the excavation equipment on the excavation platform, and parking the dump truck near the excavation platform, but it is necessary to provide enough platforms to meet the needs of earth excavation at different locations.
[0041] For example, Figure 5 , Figure 6 An ultra-deep and ultra-large foundation pit with steps is shown. The depth of the foundation pit is h>20m, and the length of the steps is d. It is necessary to provide enough platforms to meet the needs of soil excavation at different positions.
[0042] Based on this, this embodiment enables the construction platform 10 to move to a preset position through the transfer mechanism 20 to meet the soil excavation needs at different positions; at the same time, it avoids setting up more platforms, reduces the number of platforms, and helps to reduce construction costs.
[0043] It should be noted that the transfer mechanism 20 can be a transmission mechanism, for example, the transmission mechanism is a roller transmission mechanism, and the roller transmission mechanism includes a plurality of rollers, and the construction platform 10 is driven to a preset position by the rotating rollers.
[0044] The transfer mechanism 20 may include a track 22 and a sliding member 21 . The sliding member 21 moves along the extension direction of the track 22 . The sliding member 21 is connected to the construction platform 10 . The construction platform 10 is driven to a preset position by the sliding member 21 .
[0045] The transfer mechanism 20 may be a crawler mechanism or a wheel mechanism, the crawler mechanism is connected to the construction platform 10, or the wheel mechanism includes a plurality of arranged wheels, the wheel mechanism is connected to the construction platform 10, and then drives the construction platform 10 to a preset position.
[0046] Taking into account the construction cost and convenience of construction, preferably, the transfer mechanism 20 includes a track 22 and a sliding member 21 .
[0047] In practical applications, the track 22 is laid according to a preset track, and then the sliding member 21 can move to a plurality of preset positions. The construction is simple and convenient, and the construction cost is low.
[0048] Among them, Figure 2 and Figure 3 As shown, the track 22 is arranged on the foundation to prevent the track 22 from slipping. The track 22 may be a closed-loop track 22, a straight track 22, or a curved track 22.
[0049] The sliding member 21 is a crane sliding member 21 , that is, the crane sliding member 21 can withstand an extremely large load, and the sliding member 21 can still slide normally along the extending direction of the track 22 .
[0050] At least two sliding members 21 are arranged on each track 22, and the sliding members 21 are arranged at equal intervals at the bottom of the construction platform 10. Such an arrangement can reduce the pressure on the sliding member 21, and help the sliding member 21 slide along the extension direction of the track 22.
[0051] According to some embodiments of the present invention, the construction platform 10 includes a truss beam mechanism 12 and at least two second direction bearing beams 11. The second direction bearing beams 11 are located at the bottom of the truss beam mechanism 12, and the second direction bearing beams 11 extend along the width direction of the construction platform 10, and each second direction bearing beam 11 is arranged at intervals along the length direction of the construction platform 10.
[0052] It should be noted that the first direction is the length direction of the construction platform 10, that is, the X direction, and the second direction is the width direction of the construction platform 10, that is, the Y direction.
[0053] The truss beam mechanism 12 is formed by welding a plurality of beams, and the beams may be H-shaped steel, angle steel, or square steel. The truss beam mechanism 12 is welded to the second direction bearing beam 11 .
[0054] With such arrangement, the construction platform 10 has good strength, rigidity and stability, and can bear the load of the excavation equipment, while saving materials and reducing construction costs. The excavation equipment may be a crane.
[0055] Specifically, there are at least two rails 22, and the rails 22 correspond to the second direction bearing beams 11 one by one. There are multiple sliding members 21 between the second direction bearing beams 11 and the rails 22, and each sliding member 21 is welded to the second direction bearing beam 11. This arrangement prevents the sliding member 21 from shaking relative to the rails 22, thereby avoiding the problem of stagnation between the sliding member 21 and the rails 22.
[0056] like Figure 1 and Figure 2 As shown, the truss beam mechanism 12 includes a plurality of beam component units 121, a plurality of second direction upper beams 122 and a plurality of second direction lower beams 123. The beam component units 121 extend along the length direction of the construction platform 10, and the plurality of beam component units 121 are arranged at equal intervals along the width direction of the construction platform 10.
[0057] A plurality of second-direction upper beams 122 are arranged at equal intervals along the length direction of the beam assembly unit 121, and a plurality of second-direction lower beams 123 are arranged at equal intervals along the length direction of the beam assembly unit 121. A second-direction upper beam 122 and a second-direction lower beam 123 are arranged between two adjacent beam assembly units 121, the second-direction upper beam 122 is close to the upper end of the beam assembly unit 121, and the second-direction lower beam 123 is close to the lower end of the beam assembly unit 121, so as to form a frame structure. In other words, the truss beam mechanism 12 is arranged with a plurality of frame structures along the length direction of the construction platform 10, and the frame structure has good stability, which helps to improve the stability of the truss beam mechanism 12.
[0058] The beam assembly unit 121 includes a first direction upper beam 1211, a first direction lower beam 1212, a plurality of third direction beams 1213 and a plurality of reinforcing beams 1214. The first direction upper beam 1211 and the first direction lower beam 1212 extend along the length direction of the construction platform 10. The third direction beam 1213 and the reinforcing beam 1214 are arranged between the first direction upper beam 1211 and the first direction lower beam 1212. The third direction beam 1213 extends along the vertical direction.
[0059] A plurality of third directional beams 1213 are arranged at equal intervals along the length direction of the first directional upper beam 1211 or the first directional lower beam 1212 , a plurality of reinforcing beams 1214 are arranged at equal intervals along the length direction of the first directional upper beam 1211 or the first directional lower beam 1212 , and the reinforcing beams 1214 and the third directional beams 1213 are arranged alternately.
[0060] Among them, Figure 2 As shown, the first direction lower beam 1212 is connected to the second direction bearing beam 11 ; the second direction upper beam 122 is located between two adjacent first direction beams 1211 , and the second direction lower beam 123 is located between two adjacent first direction lower beams 1212 .
[0061] Two adjacent third directional beams 1213, the first directional upper beam 1211, and the first directional lower beam 1212 form a closed rectangular space, and the reinforcing beam 1214 divides the rectangular space into two triangular structures. In other words, the beam assembly unit 121 is arranged with a plurality of triangular structures along the length direction of the construction platform 10, and the triangular structure has good stability, which helps to improve the stability of the truss beam mechanism 12.
[0062] In addition, if Figure 1 and Figure 2 As shown, the construction platform 10 further includes a corrugated plate 14 and a plurality of second direction auxiliary beams 13, the second direction auxiliary beams 13 are located at the top of the truss beams, the second direction auxiliary beams 13 extend along the width direction of the construction platform 10, and the second direction auxiliary beams 13 are arranged at equal intervals along the length direction of the construction platform 10. The corrugated plate 14 is laid on each second direction auxiliary beam 13.
[0063] The corrugated plate 14 can provide sufficient friction so that the excavating equipment can operate stably on the construction platform 10 and avoid slipping.
[0064] In practical applications, if the track 22 can be a closed-loop track 22, N construction platforms 10 can be provided, where N is a positive integer, 1≤N≤3.
[0065] N=3 or 2, the platform can be set at the corner of the foundation pit.
