[0002] With the rapid development of transportation, especially the advancement of large-scale infrastructure construction, bridges occupy an important position in highway design. During bridge construction, underwater bored pile construction is often required on water surfaces. Current methods necessitate the construction of these piles on pre-built trestle platforms, requiring the removal of the trestle's deck panels during drilling and the installation of edge protection measures after completion. As the number of piles increases, this method becomes increasingly complex, slow, and time-consuming. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a mobile construction platform for underwater bored piles, which aims to solve the technical problems of cumbersome construction procedures and low construction efficiency of the existing trestle platform construction method.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a mobile construction platform for underwater bored piles, which includes multiple steel casings arranged in a matrix. All steel casings located at the same horizontal position form a horizontal row of steel casings, and all steel casings located at the same vertical position form a vertical row of steel casings.

[0006] Support legs are symmetrically arranged on both sides of the steel casing. The support legs are located in the transverse direction of the steel casing. A track load-bearing beam is provided on each row of steel casings. The track load-bearing beam has a track.

[0007] At least one truss platform is provided on the track load-bearing beam. The bottom of the truss platform is provided with a support frame, and the bottom end of the support frame is provided with a brake roller, which is located on the track.

[0008] When in use, a drilling rig, an air compressor, and / or a muck tank and / or a mud tank are installed on top of the truss platform.

[0009] To reduce raw material consumption, the above solution further includes: the track support beam is an I-beam, the bottom plate of which is fixed to the support leg by bolts, and the track is fixed to the top plate of the I-beam by bolts.

[0010] To further improve construction efficiency, the above scheme further includes: two truss platforms, one of which is equipped with a drilling rig and an air compressor on its top, and the other of which is equipped with a slag box and a mud box on its top.

[0011] The beneficial effects of this utility model are:

[0012] (1) Because the process of setting up a drilling platform before drilling is eliminated, the construction period is shortened, thereby improving construction efficiency.

[0013] (2) It saves the steel required for erecting the drilling platform, reduces the amount of steel used, and lowers construction costs.

[0014] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0022] Furthermore, the reference numbers and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or settings discussed.

[0023] like Figures 1 to 4 As shown, the mobile construction platform for underwater bored piles mentioned in this utility model includes multiple steel casings 1 arranged in a matrix. All steel casings 1 located at the same horizontal position form a horizontal row of steel casings, and all steel casings 1 located at the same vertical position form a vertical row of steel casings.

[0024] Support legs 2 are symmetrically arranged on both sides of the steel casing 1. The support legs 2 are located in the transverse direction of the steel casing 1. A track bearing beam 3 is provided on each row of steel casings. The track bearing beam 3 has a track 4.

[0025] At least one truss platform 5 is provided on the track load-bearing beam 3. A support frame 6 is provided at the bottom of the truss platform 5. A brake roller 7 is provided at the bottom end of the support frame 6. The brake roller 7 is located on the track 4.

[0026] In use, a drilling rig 8, an air compressor 9, and / or a soil container 10 and / or a mud container 11 are installed on top of the truss platform 5. In this embodiment, the truss platform 5 can be moved to the required position on the track 4 according to the needs of pile foundation construction. The brake roller 7 is then braked by the worker manually adjusting the clamping device on the brake roller 7, thus positioning the truss platform 5 at the designated position in the pile group construction area 12. In specific implementation, the truss platform 5 is fabricated on the main trestle bridge. This truss platform 5 provides working space for the drilling rig 8. Compared with existing technologies, the truss platform 5 reduces steel consumption and can be reused, reducing construction steps, improving construction efficiency, and reducing construction costs. The air compressor 9 is pneumatically connected to the drilling rig 8 via pipelines, and the air compressor 9 is connected to the soil container 10 and the mud container 11 via discharge pipelines.

[0027] To reduce raw material consumption, in the above embodiment, preferably, the track support beam 3 is an I-beam, the bottom plate of which is bolted to the support leg 2, and the track 4 is bolted to the top plate of the I-beam. In this embodiment, the I-beam can be a recycled product from other construction steps.

[0028] To further improve construction efficiency, in the above embodiment, preferably, two truss platforms 5 are used. One truss platform 5 has a drilling rig 8 and an air compressor 9 mounted on its top, while the other truss platform 5 has a slag box 10 and a mud box 11 mounted on its top. In this embodiment, the combined use of two truss platforms 5 further improves the construction efficiency of steel casing driving and pile foundation drilling.

[0029] In the above embodiments, all components are commercially available products.

[0030] The construction steps of the structure described in this utility model are as follows:

[0031] (1) Construct a truss platform 5 on the main trestle bridge. The dimensions of the truss platform 5 are based on the short side direction of the area 12 to be constructed across the pile group.

[0032] (2) The steel casing 1 of the pile foundation is driven in a row by row using the fishing method. The supporting legs 2 on the steel casing 1 and the I-beams on the supporting legs 2 serve as the load-bearing structure. The supporting legs 2 are welded to the steel casing 1, and the I-beams are welded to the supporting legs 2 or bolted together. When two truss platforms 5 are used, one truss platform 5 is in front for the driving operation, and the other truss platform 5 supplies the steel casing 1 with material.

[0033] (3) As the steel casing 1 is inserted, the multi-segment H-beams and the multi-segment rails 4 located on the top plate of the H-beams extend forward one span at a time. The rails 4 are connected to the H-beams by welding or bolting.

[0034] (4) After the steel casing 1 is completed, the truss platform 5 returns, and the drilling rig 8 climbs onto the platform to carry out drilling operations. The drill cuttings generated during the drilling operation of the drilling rig 8 are discharged into the slag box 10 and / or the mud box 11. When two truss platforms 5 are used, one truss platform 5 is used to house the drilling rig 8 and the air compressor 9, while the other truss platform 5 is used to transport materials such as drill cuttings and concrete.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
