Description

Technical Field

[0001] This invention relates to a construction method for a novel intelligent control multifunctional slipform concrete machine, belonging to the technical field of road and bridge construction methods. Background Technology

[0002] UHPC concrete, also known as ultra-high performance concrete, is a special type of concrete with ultra-high strength, ultra-low water absorption, and superior durability and corrosion resistance. It differs from ordinary concrete in many aspects, including raw materials, mix proportions, and workability.

[0003] In the paving construction of UHPC concrete, the traditional construction equipment for ordinary concrete cannot fully utilize the performance of UHPC concrete. Based on the above characteristics of UHPC concrete and combined with the characteristics of the site and construction conditions, a new type of UHPC integrated machine for laying, leveling and covering film has been developed to realize the integrated paving construction operation of laying, leveling and covering film for UHPC concrete. Summary of the Invention

[0004] The purpose of this invention is to provide a novel integrated machine for UHPC concrete laying, leveling, and film coating, so as to realize the integrated paving construction operation of laying, leveling, and film coating for UHPC concrete.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A construction method for a novel intelligent control multi-functional slipform concrete machine is disclosed. The slipform machine includes a traveling mechanism, a lifting mechanism, a material placing mechanism, a leveling mechanism, a finishing mechanism, and a film covering mechanism mounted on the traveling mechanism. The material placing mechanism is installed on the main frame beam, and both ends of the main frame beam are connected to the lifting mechanism. The leveling mechanism, finishing mechanism, and film covering mechanism are sequentially arranged behind the material placing mechanism. The finishing mechanism moves laterally to smooth the leveled road surface. The film covering mechanism applies a film to the smoothed road surface longitudinally. The machine is controlled by a control system.

[0007] The construction method is as follows:

[0008] The machine moves forward at a certain speed. The material-laying mechanism lays the material, the leveling mechanism levels the surface after the material is laid, the finishing mechanism smooths the surface after leveling, and the film-coating mechanism coats the smoothed surface with film.

[0009] The construction road surface is a two-way road surface of the bridge, divided into the A-direction road surface and the B-direction road surface; the A-direction road surface is divided into several construction area blocks denoted as A1, A2, A3...An; the B-direction road surface is divided into several construction area blocks denoted as B1, B2, B3...Bn; construction is carried out back and forth between the area blocks of the A-direction road surface and the area blocks of the B-direction road surface to maintain the balance of the bridge deck.

[0010] A further improvement to the technical solution of this invention is as follows: the machine moves forward during construction as follows:

[0011] First, construct area A1 in direction A. After completing area A1 in direction A, move the machine to area B1 in direction B and back to the starting point of area B1 to construct area B1 and area B2 in direction B. After completing area B2, move the machine to area A2 and back to the starting point of area A2 to construct area A2 and area A3. Then, move the machine to area B3 in direction B and back to the starting point of area B3 to construct area B3 and area B4 in direction B. Continue this process for each area block.

[0012] A further improvement to the technical solution of the present invention is as follows: the material distribution mechanism includes a pump pipe, the inlet of which is connected to the pump truck; two sets of pump pipes are provided, and the inlets of the pump pipes are located at both ends of the main frame beam; when changing construction areas in different directions, different pump pipes are switched at the same time for material supply and transportation.

[0013] A further improvement to the technical solution of the present invention is that a crane is used to move the machine when it is translating between the road surface in direction A and the road surface in direction B.

[0014] A further improvement to the technical solution of the present invention is as follows: a lateral translation mechanism is provided on the machine, the lateral translation mechanism includes a translation wheel and a winch that provides traction force, and the height of the translation wheel is adjustable; the machine moves using the lateral translation mechanism when translating between the road surface in direction A and the road surface in direction B.

[0015] A further improvement to the technical solution of the present invention is that the control signal receiver is a laser receiver or an ultrasonic receiver or an RTK positioner is set.

[0016] A further improvement to the technical solution of the present invention is as follows: when the control signal receiver is a laser receiver, the overall elevation control adopts a three-dimensional laser system control, inputs elevation and mileage data, receives signals from the laser receivers on both sides, and transmits them to the controller to realize the automatic adjustment of the whole machine.

[0017] A further improvement to the technical solution of the present invention is as follows: the lateral translation mechanism is provided with several translation wheels; when the lateral translation mechanism crosses the intermediate guardrail, the translation wheel at the forefront in the forward direction is raised upward, and then the translation wheel crosses the intermediate guardrail. After crossing the intermediate guardrail, the translation wheel falls down to support the machine; when subsequent translation wheels need to cross the intermediate guardrail, they are also raised upward, and after crossing, the translation wheels fall down to support the machine.

[0018] Due to the adoption of the above technical solution, the technical effects achieved by this invention are as follows:

[0019] This invention is a UHPC integrated machine for fabric laying, leveling, and film coating. This machine can realize the integrated construction of fabric laying, leveling, and film coating. The machine has a compact structure and high construction efficiency. Using this machine can save labor, is easy to operate, and ensures smooth construction, while guaranteeing a high degree of surface flatness.

[0020] This invention sets up a material-laying trolley that works in conjunction with a secondary buffer bin for material laying. The material-laying trolley lays the material into the secondary buffer bin, which then lays the material evenly. This improves the uniformity of the material laying and lays a good foundation for subsequent leveling operations.

[0021] This invention provides a drag chain pump pipe for the fabric placing trolley, and also includes a mobile pump truck and a cement mixer truck, which can continuously supply material to the moving fabric placing trolley, improving the continuity and efficiency of the work.

[0022] This invention features two sets of cable chain pump pipes, with the inlets of each set located at both ends of the main beam. By using two sets of cable chains for concrete transport, it can better adapt to different construction areas and reduce modification difficulties. It also facilitates adjustments when switching from the construction side to the opposite lane.

[0023] This invention performs leveling immediately after the material is laid, which improves the leveling quality. The invention also includes a finishing mechanism that allows for immediate smoothing and finishing of the surface after leveling, further enhancing the quality of the road surface.

[0024] This invention allows for immediate film covering and curing after the surface is smoothed and finished, enabling integrated paving and curing operations and improving the quality of concrete curing.

[0025] The present invention provides a lateral translation mechanism and a traction winch for lateral machine movement, which enables the machine to be moved laterally to change the construction area.

[0026] This invention incorporates laser receivers, and the overall machine elevation control utilizes a three-dimensional laser system. Elevation and mileage data are directly input, and the laser receivers on both sides receive the signals, transmitting them to the controller to achieve automatic adjustment of the entire machine. This eliminates the need for ultrasonic testing that relies on mounting brackets and steel wires to indicate elevation, reducing errors caused by manual elevation adjustments.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] This invention relates to a novel intelligent control multi-functional slipform paving machine construction method for UHPC concrete, primarily used for integrated paving construction including material placement, leveling, surface finishing, and membrane covering. The terms "forward" and "rear" below refer to the machine's direction of travel; the direction the machine is moving forward is considered "forward."

[0035] like Figure 1 , Figure 3 , Figure 4 As shown, the machine mainly comprises a traveling mechanism 6, a lifting mechanism 2, a concrete placing mechanism, a leveling mechanism, a finishing mechanism, and a film covering mechanism. The traveling mechanism drives the entire machine longitudinally. The lifting mechanism 2 is installed on the traveling mechanism. The machine has a main frame beam 1, the two ends of which are hinged to the lifting ends of the lifting mechanism 2. The concrete placing mechanism is installed on the main frame beam 1 and is used to evenly distribute the concrete material. The lifting mechanism adjusts the height, thereby controlling the elevation of the paved road surface. The machine is under the overall construction control of a control system. The signal receiver of the control system can be a laser receiver, an ultrasonic receiver, or an RTK positioner.

[0036] The leveling mechanism is located behind the concrete placing mechanism and is used to level the placed concrete material by lifting and smoothing it.

[0037] The finishing mechanism is located behind the material spreading mechanism and is used to perform fine finishing and smoothing on the leveled concrete surface.

[0038] The film covering mechanism is located behind the finishing mechanism and is equipped with a curing film for covering the concrete surface to facilitate subsequent concrete curing.

[0039] A laser receiver 14 is installed on the walking mechanism 2 at the position of the lifting mechanism. The whole machine elevation control adopts a three-dimensional laser system control. The elevation and mileage data are directly input, and the laser receivers on both sides receive the signals and transmit them to the controller to realize the automatic adjustment of the whole machine. This eliminates the process of using ultrasonic installation brackets and steel wires to reflect the elevation, and reduces the error of human error in reflecting the elevation.

[0040] The machine is controlled by a control system, and the specific construction method is as follows.

[0041] The machine moves forward at a certain speed, with the material-laying mechanism spreading the material and the leveling mechanism leveling the surface after the material is spread. The finishing mechanism smooths and finishes the leveled surface, and the film-coating mechanism applies a film to the smoothed surface.

[0042] This machine and its construction method are primarily suitable for large, two-way road surfaces. To maintain balance, construction needs to be carried out back and forth between the two road surfaces. Specifically, the two road surfaces are denoted as A-direction road surface and B-direction road surface; A-direction road surface is divided into several construction area blocks denoted as A1, A2, A3...An; B-direction road surface is divided into several construction area blocks denoted as B1, B2, B3...Bn. The machine works back and forth between the area blocks of A-direction road surface and the area blocks of B-direction road surface to maintain the balance of the bridge deck.

[0043] like Figure 1 , Figure 2 As shown, the machine moves forward in the following manner during construction.

[0044] First, construction begins on block A1 in direction A. After completing block A1, the machine is moved to block B1 in direction B, returning to its starting point, to begin construction on blocks B1 and B2 in direction B. After completing block B2, the machine is moved to block A2, returning to its starting point, to begin construction on blocks A2 and A3. Then, the machine is moved to block B3 in direction B, returning to its starting point, to begin construction on blocks B3 and B4 in direction B. This process is repeated for each block. This method of movement achieves the best construction efficiency while maintaining the bridge's balance and ensuring construction safety. When moving on unconstructed surfaces, a construction path needs to be created to facilitate the laying of steel plates.

[0045] The machine's concrete placing mechanism includes pump pipes that connect the material source and the material placing mechanism's inlet. The inlet of the pump pipes is connected to the pump truck. Preferably, two sets of pump pipes are provided, with their inlets located at both ends of the main frame beam. This makes it more convenient to switch between different pump pipes for material supply when changing construction areas in different directions. By using two sets of cable carriers for concrete material transport, it can better adapt to different construction areas and reduce modification difficulty. When switching from the construction side to the opposite lane, it is only necessary to disconnect the mobile pump truck 17 from the machine's travel point, disconnect the existing cable carrier pump pipe 6, hoist the machine to the opposite lane, and then install the mobile pump truck 17 at the other end of the machine's travel point, connecting it to the other set of cable carrier pump pipes 6, and construction can begin. Other procedures remain unchanged, thus meeting the construction requirements.

[0046] During the implementation of this method, the machine needs to be continuously moved horizontally. Two main methods are used to achieve this movement: one is by using a large crane; the other is through the machine's own lateral translation mechanism.

[0047] Regarding the machine's lateral translation mechanism, the lateral translation mechanism includes translation wheels for lateral movement and a winch 15. The lateral translation mechanism is installed on both sides of the main frame beam 1, enabling the machine to be moved laterally to change the construction area. Specifically, the translation wheels 16 are located on the front and rear sides of the main frame beam 1, and are mounted on both sides of the main frame beam 1 via lifting hydraulic cylinders. The winch 15 is fixedly installed on the upper part of both ends of the main frame beam 1, providing the driving force for translation. The winch 15's wire extends to a stable fixed point; or the winch 15 extends to a fixed point, passes over a pulley at the fixed point, and then returns and is fixed to the machine again.

[0048] The machine's lateral translation mechanism is equipped with several translation wheels 16 to ensure smooth translation. When using the lateral translation mechanism to cross the intermediate guardrail, the foremost translation wheel in the forward direction rises and then crosses the intermediate guardrail, while the other translation wheels remain in a normal support state during this process. After crossing the intermediate guardrail, the foremost translation wheel falls back down to support the machine; subsequent translation wheels also rise when they need to cross the intermediate guardrail, and fall back down to support the machine after crossing. During the crossing of the intermediate guardrail, all translation wheels except the one crossing the intermediate guardrail must be in a support state. After crossing, the translation wheels fall back down to switch to a support state. The switching process of the translation wheels is described in [details omitted]. Figure 5 .

[0049] This invention is an integrated machine for fabric laying, leveling, and film coating. It combines fabric laying, vibration leveling, surface finishing, and film coating into one machine. It features a compact structure, high construction efficiency, labor saving, convenient operation, smooth construction, and high surface flatness.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
