Description

Technical Field

[0001] This utility model relates to the field of reservoir riverbed cast-in-place pile construction technology, specifically a water surface operation auxiliary device for reservoir riverbed cast-in-place pile construction. Background Technology

[0002] During the flood season, high-sediment-laden water flows carry large amounts of bedload, impacting the riverbed in front of the intake and causing severe erosion damage to the hydraulic structures used for flood discharge and power generation. To effectively enhance the protective performance of these structures, concrete piles are often poured into the riverbed in front of the intake to resist water erosion and ensure the safety and stability of the structures.

[0003] When constructing concrete piles on a reservoir riverbed, mobile piling vessels are generally used because the construction surface is underwater. Common piling vessels are 25–40 meters long and weigh 100–200 tons. They are typically equipped with a pile hammer, a pile frame, and auxiliary equipment. The pile hammer is mounted between two parallel vertical guide rods at the front of the pile frame at the bow of the vessel. The hammer is lifted by the pile frame and its direction is controlled by the guide frame.

[0004] However, in reservoir construction along some rivers in northern China, the large depth of the reservoirs and the shallowness of the upstream and downstream channels prevent large integrated piling vessels from being transported to the construction area via waterways. Furthermore, the sheer size of the piling vessels makes land transportation difficult and impractical. Therefore, in these remote and inaccessible reservoirs, traditional underwater concrete pile construction methods are difficult to implement smoothly. Utility Model Content

[0005] To address the problem that large integrated piling vessels cannot be transported to the construction area via waterways during reservoir construction in some northern rivers, hindering the smooth implementation of traditional underwater concrete pile construction methods, this invention provides a surface operation auxiliary device for reservoir riverbed pile construction. This auxiliary device enables drilling in reservoirs with inconvenient transportation and isolated environments, allowing for the smooth implementation of underwater concrete pile construction, thereby saving equipment investment, shortening the construction period, and reducing project construction costs.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a water surface operation auxiliary device for the construction of cast-in-place piles in a reservoir riverbed, comprising two platforms, which are located on the water surface, and there is a distance between the two platforms to form a channel for drilling rig construction. The platforms are provided with guide rails for supporting the drilling rig, and the guide rails on the two platforms are parallel to each other. Connecting parts are detachably connected to the guide rails, and the connecting parts are fixedly set on the drilling rig base.

[0007] As a further optimization of the water surface operation auxiliary device for the construction of cast-in-place piles in a reservoir riverbed, the platform includes multiple floating bridge vessels located on the same straight line, and adjacent floating bridge vessels are connected by the guide rail.

[0008] As a further optimization of the auxiliary device for water surface operation in reservoir riverbed grouting pile construction, the length of the floating bridge vessel is set to 15-20m, the width to 5-8m, and the height to 1.5-2m.

[0009] As a further optimization of the auxiliary device for water surface operation in reservoir riverbed grouting pile construction, the guide rail and the connector are connected by multiple pins. The guide rail is provided with a number of first positioning pin holes, which are distributed along the length of the guide rail. The connector is provided with a number of second positioning pin holes. The pin passes through one of the second positioning pin holes and one of the first positioning pin holes in sequence to fix the guide rail and the connector.

[0010] As a further optimization of the water surface operation auxiliary device for the construction of cast-in-place piles in reservoir riverbeds, the distance between any two adjacent first positioning pin holes is equal.

[0011] As a further optimization of the water surface operation auxiliary device for the construction of cast-in-place piles in reservoir riverbeds, the distance between any two adjacent first positioning pin holes is set to 1.0 to 1.2m.

[0012] As a further optimization of the water surface operation auxiliary device for the construction of cast-in-place piles in a reservoir riverbed, the second positioning pin hole is set to two, and the distance between the two second positioning pin holes is set to 2.3~2.5m.

[0013] As a further optimization of the auxiliary device for water surface operation in reservoir riverbed grouting pile construction, the diameter of the first positioning pin hole and the diameter of the second positioning pin hole are both 5-7 cm.

[0014] As a further optimization of the water surface operation auxiliary device for the construction of cast-in-place piles in a reservoir riverbed, the distance between the two platforms is set to 1.3 to 1.5 m.

[0015] As a further optimization of the auxiliary device for water surface operation in reservoir riverbed grouting pile construction, the guide rail is set as an I-beam and the connecting part is set as a channel steel.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features two platforms positioned on the water surface, with a distance between them to create a channel for the drilling rig. Each platform has parallel guide rails to support the rig, and these rails are detachably connected to the guide rails. The connecting parts are fixed to the rig's base. After completing one hole, the rig moves forward a certain distance to the next hole to drill, thus improving the drilling efficiency and saving on equipment investment, construction time, and project costs.

[0024] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as the model of drilling rig 3, the model of pin 6, the structure of floating bridge ship, the model of steel truss, the model and structure of truck crane, etc.

[0025] Example 1

[0026] A surface operation auxiliary device for the construction of cast-in-place piles in a reservoir riverbed, such as... Figures 1 to 5 As shown, the system includes two platforms 1, which are located on the water surface. A distance exists between the two platforms 1 to form a channel 2 for the drilling rig 3 to operate. Guide rails 5 are installed on each platform 1 to support the drilling rig 3, and the guide rails 5 on the two platforms 1 are parallel to each other. Connecting members 7 are detachably connected to the guide rails 5 and are fixedly mounted on the base of the drilling rig 3. The distance between the two platforms 1 is set to 1.3–1.5 m. The optimal distance between the two platforms 1 is set to 1.4 m.

[0027] When carrying out the construction of cast-in-place piles in the riverbed of the reservoir, such as Figure 1 As shown, firstly, two parallel platforms 1 are constructed, with a 1.4m distance reserved between the two platforms 1 to form a passage 2 for the drilling rig 3 to operate; as Figure 5 As shown, the base of drill 3 is placed on guide rail 5, with connector 7 attached to the side of guide rail 5 facing away from the other guide rail 5. The base is then slid to change the position of drill 3, and during this sliding motion, connector 7 moves synchronously. Because connector 7 is attached to the side of guide rail 5, guide rail 5 can restrict the movement direction of connector 7, thus restricting the movement direction of drill 3, ultimately controlling the direction of drill 3. Once drill 3 has moved to the appropriate position, connector 7 is connected to guide rail 5 to fix its position. Finally, drill 3 is used for drilling. After completing one hole 4, drill 3 moves forward a fixed distance to the next hole and continues working, maintaining the same distance each time.

[0028] This embodiment uses four impact drilling rigs 3, each measuring 6m in length and 2m in width. Depending on actual needs, an appropriate number of drilling rigs 3 can be installed on platform 1.

[0029] This invention arranges a platform 1 on the water surface, and a suitable drilling rig 3 is placed on the platform 1, which can save the space of the platform 1 and improve the space utilization rate. Furthermore, the arrangement of guide rails 5 and connecting parts 7 that cooperate with the guide rails 5 on the platform 1 can safely fix and quickly move the drilling rig 3, so that the drilling rig 3 can reach the appropriate position, thereby improving the construction efficiency of the drilling rig 3. This achieves the effects of saving equipment investment, shortening the construction period, and reducing the investment cost of project construction.

[0030] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

A 50-ton truck crane is used at the reservoir dock to arrange the six floating bridge vessels side-by-side in a row of three vessels on each side, with a distance of 1.4 meters between each row. The bottom of the floating bridge vessels is welded and fixed using pre-calculated steel trusses to ensure that their structural strength meets design requirements.
