Description

Technical Field

[0001] The present invention relates to the technical field of underwater construction, and more specifically, to a method for hoisting a water intake head of a water intake pump station. Background Art

[0002] The intake head refers to the water intake portion of a riverbed-type water intake structure. It's typically located in the center of a river or stream. River water is introduced into the pump station through two intake pipes, then into the forebay. Electric butterfly valves then divert water to the pump station's cross-flow pumps, where it is then supplied to major water plants within the city for drinking water.

[0003] The current method for hoisting the water intake head is to install and fix the water intake head on the shore, and then use a crane to lift the entire water intake head and transport it to the installation location in the water. Due to the large size and heavy weight of the water intake head, generally 8 meters * 8 meters * 29 meters, and the total weight of nearly 900 tons, it is necessary to use a large lifting tonnage crane ship to enter the site for hoisting. After entering the site, the ship needs to be assembled again, and the water intake head is directly hoisted after assembly. Since the assembly of the large lifting tonnage crane ship is more complicated, the construction time is extended and the cost is high. Directly hoisting the entire water intake head, which is a concrete structure, is easily damaged.

[0004] In summary, the current method of using a large lifting tonnage crane vessel to lift the water intake head as a whole has the problems of being time-consuming, inefficient, expensive, and easily causing damage to the water intake head. Summary of the Invention

[0005] In view of the above problems, the purpose of the present invention is to provide a method for lifting the water intake head of a water intake pump station to solve the problems in the existing technology of using a super-large lifting tonnage lifting ship to lift the water intake head as a whole, which is time-consuming, inefficient, expensive, and easy to cause damage to the water intake head.

[0006] The present invention provides a method for hoisting a water intake head of a water intake pump station, comprising the following steps:

[0007] Divide the water intake head to be hoisted into blocks according to the preset block drawing, and divide each block into upper and lower layers to obtain upper block units and lower block units corresponding to the upper block units;

[0008] Installing a hoisting frame on the lower block unit, fixing a hoisting device on a hoisting point of the hoisting frame, vertically hoisting the lower block unit by the hoisting device to a preset installation position, and lowering the lower block unit from above the water surface of the preset installation position to the preset installation position underwater;

[0009] After all the lower block units are placed in the preset installation positions, the adjacent lower block units are assembled and fixed underwater to obtain the lower unit of the water intake head;

[0010] Using the same hoisting method as the lower block unit, hoist the upper block unit down to the top of the lower unit, so that each upper block unit is located above its corresponding lower block unit, and assemble and fix the adjacent upper block units to obtain the upper unit of the water intake head;

[0011] The upper unit and the lower unit are fixed correspondingly to complete the hoisting of the water intake head.

[0012] In addition, a preferred solution is that the method further comprises:

[0013] A waterproof camera device and an underwater sonar signal simulation device are installed at the preset installation position, and the waterproof camera device and the underwater sonar signal simulation device are both connected to an observation device set up on the shore through signals;

[0014] The entire process of hoisting the water intake head is filmed and simulated by the waterproof camera device and the underwater sonar signal simulation device, and the filmed images and simulated scenes are transmitted to the observation device in the form of signals.

[0015] In addition, a preferred solution is that the water intake head is made of reinforced concrete and is spindle-shaped.

[0016] In addition, a preferred solution is that the hanging frame includes two shapes of hanging frames, namely a trapezoidal hanging frame and a rectangular hanging frame; wherein,

[0017] The trapezoidal hoisting frame is used to hoist the upper block unit and the lower block unit located at both ends obtained after the water intake head is divided into blocks;

[0018] The rectangular hoisting frame is used for hoisting the upper block unit and the lower block unit located in the middle obtained after the water intake head is partially blocked.

[0019] In addition, a preferred solution is that the trapezoidal hanging frame includes a trapezoidal frame and a reinforcing beam arranged inside the trapezoidal frame; the rectangular hanging frame includes a rectangular frame and a reinforcing beam arranged inside the rectangular frame.

[0020] In addition, a preferred solution is that the hoisting frame is formed by welding I-beams; and a hoisting point is provided on the top of the hoisting frame.

[0021] In addition, a preferred solution is that the hoisting frame is installed on the lower block unit, the hoisting equipment is fixed on the hoisting point of the hoisting frame, the lower block unit is vertically hoisted and transported to a preset installation position by the hoisting equipment, and the lowering from the water surface of the preset installation position to the preset installation position under water includes:

[0022] The hoisting frame is fixedly installed on the upper pre-buried anchor point of the lower block unit to obtain a unit to be hoisted;

[0023] Installing a GPS measuring instrument on the unit to be hoisted, and fixing the hoisting equipment on the hoisting point of the hoisting frame;

[0024] The unit to be hoisted is lifted vertically by using the hoisting equipment, and is transported to a preset installation position according to the GPS measuring instrument, and is lowered from above the water surface of the preset installation position to the preset installation position underwater.

[0029] In addition, a preferred solution is that, in the process of vertically lifting and transporting the lower block unit to the preset installation position by the lifting equipment, and lowering it from the water surface above the preset installation position to the underwater preset installation position,

[0030] By installing a measuring rod at each lifting point of the lifting frame, the lifting height of each lifting point during the lifting process is measured;

[0031] When the lifting height deviation is greater than a preset deviation threshold, the lifting height of each lifting point is leveled so that the lifting height deviation is less than the preset deviation threshold; wherein the lifting height deviation is the maximum difference between the lifting points during lifting.

[0032] From the above technical solution, it can be seen that the water intake head hoisting method of the water intake pump station provided by the present invention adopts the upper and lower block production method on the shore and the underwater assembly and combination method, and uses the grooves between the upper and lower blocks to rivet and fix them with stainless steel connecting plates. Compared with the traditional integral production and hoisting method, it can effectively avoid the arrival of ultra-large hoisting tonnage lifting ships and the time and cost of reassembling the ships; and during hoisting, the block units divided by the hoisting frame are used for fixing and protection, which effectively ensures the stability of the concrete structure.

[0042] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. However, it will be apparent that these embodiments may be practiced without these specific details.

[0043] In view of the problems in the above-mentioned prior art of using a large lifting tonnage crane vessel to lift the water intake head as a whole, such as being time-consuming, inefficient, expensive, and easily damaging the water intake head, a method for lifting the water intake head of a water intake pump station is proposed.

[0044] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] In order to illustrate the water intake head hoisting method of the water intake pump station provided by the present invention, Figure 1 The flowchart of the method for hoisting the water intake head of the water intake pump station according to an embodiment of the present invention is shown; Figure 2 The underwater structure of the water intake head according to an embodiment of the present invention is shown; Figure 3 The figure shows the hoisting process of the lower block unit according to an embodiment of the present invention; Figure 4 The structure of a trapezoidal hanging frame according to an embodiment of the present invention is shown; Figure 5 The structure of a rectangular hanging frame according to an embodiment of the present invention is shown.

[0046] like Figures 1 to 5 As shown together, the method for hoisting the water intake head of the water intake pump station provided by the present invention includes the following steps:

[0047] S1, according to the preset block drawing, the water intake head 2 to be hoisted is divided into blocks, and each block is divided into upper and lower layers to obtain upper block units and lower block units 21 corresponding to the upper block units;

[0048] S2. Install a hoisting frame 5 on the lower block unit 2, fix the hoisting device 6 on the hoisting point 51 of the hoisting frame 5, vertically lift the lower block unit 21 by the hoisting device 6 and transport it to the preset installation position, and lower it from the water surface above the preset installation position to the preset installation position underwater;

[0049] S3. After all the lower block units 21 are placed in the preset installation positions, the adjacent lower block units 21 are assembled and fixed underwater to obtain the lower unit of the water intake head;

[0050] S4. Using the same hoisting method as the lower block units, hoist the upper block units down to the top of the lower units, so that each upper block unit is located above its corresponding lower block unit, and assemble and fix the adjacent upper block units to obtain the upper unit of the water intake head;

[0051] S5. Fix the upper unit and the lower unit accordingly to complete the hoisting of the water intake head.

[0052] A water intake head manufacturing plant 1 is pre-built on the shore, and a water intake head 2 is manufactured in the water intake head manufacturing plant 1. During the manufacturing process, the water intake head 3 is divided into blocks according to the preset block drawings to obtain upper block units and lower block units 21. After the water intake head 2 is assembled underwater, it is connected to the pump station 4 by installing the gravity pipe 3.

[0053] By adopting the shore-based upper and lower block production method, the underwater assembly and combination method, and using the grooves between the upper and lower blocks and riveting with stainless steel connecting plates, compared with the traditional integral production and lifting method, it can effectively avoid the arrival of ultra-large lifting tonnage crane ships and the time and cost of reassembling the ships; and during lifting, the block units divided by the lifting frame are used for fixing and protection, effectively ensuring the stability of the concrete structure.

[0054] As a preferred embodiment of the present invention, the method further comprises:

[0055] A waterproof camera device and an underwater sonar signal simulation device are installed at a preset installation location, and the waterproof camera device and the underwater sonar signal simulation device are connected to the observation equipment installed on the shore through signals;

[0056] The entire process of hoisting the water intake head 2 is filmed and simulated by a waterproof camera device and an underwater sonar signal simulation device, and the filmed images and simulated scenes are transmitted to the observation equipment in the form of signals.

[0057] Through the feedback of acoustic wave signals, the underwater contours are simulated, which can not only meet the design requirements, but also make the hidden visible, effectively enhance quality and safety monitoring, speed up the construction progress, and reduce project costs. Compared with traditional measurement with frogman diving cooperation, it can greatly improve the construction accuracy and efficiency.

[0058] As a preferred solution of the present invention, the water intake head 2 is made of reinforced concrete and is spindle-shaped.

[0059] Taking the Yongjiang River water intake project as an example, the water intake head 2 is located on the north side of the main channel of the Yongjiang River. When the water level of this section of the river is normal (normal water level is 75.50 meters), the construction water depth of the water area where the water intake head 2 is located is 20 meters, and the water flow is about 0.2-0.4 meters per second. The plane of the water intake head is spindle-shaped, with length * width * height = 28.3 meters * 7.9 meters * 8.85 meters. The upstream and downstream ends of the water intake head 2 are triangular pointed heads, which are conducive to head diversion and avoiding sediments in the riverbed. The top surface of the head is designed to be 64.5 meters high, and the bottom surface is designed to be 55.65 meters high. The head is a reinforced concrete structure with a total concrete volume of approximately 316 cubic meters and a total weight of approximately 790 tons. To facilitate component prefabrication and underwater installation and construction, the head structure is divided into two layers, upper and lower. Each layer is divided into four blocks along the central axis of the head structure plane, totaling eight blocks.

[0060] As a preferred solution of the present invention, the hanging frame 5 includes two shapes of hanging frames, namely a trapezoidal hanging frame and a rectangular hanging frame; wherein,

[0061] The trapezoidal lifting frame is used to lift the upper block unit and the lower block unit at both ends obtained after the water head partial block is lifted;

[0062] The rectangular hoisting frame is used to hoist the upper block unit and the lower block unit located in the middle obtained after the water head partial block is taken.

[0063] In order to avoid the symmetrical inward pressure caused by the direct lifting of the water intake head 2 of the reinforced concrete component, it is fixed to the four lifting points 51 of the lifting frame 5 by steel wire ropes 7, and it should be as perpendicular to the force-bearing lifting points 51 as possible. In order to better protect the shuttle-shaped water intake head 2, two structures of lifting frames 5 are made.

[0064] As a preferred embodiment of the present invention, the trapezoidal hanging frame includes a trapezoidal frame and a reinforcing beam disposed inside the trapezoidal frame; the rectangular hanging frame includes a rectangular frame and a reinforcing beam disposed inside the rectangular frame. The frame and the reinforcing beam make the structure firm.

[0065] As a preferred embodiment of the present invention, the hoisting frame 5 is welded from I-beams; a hoisting point 51 is provided at the top of the hoisting frame 5. To meet practical needs, a special hoisting device is used, which is made by cutting and splicing I-beams (I 30b), and is fully welded by cutting and splicing. The webs on both sides of the contact points are reinforced with t=18 steel plates.

[0066] As a preferred solution of the present invention, a hoisting frame 5 is installed on the lower block unit 21, a hoisting device 6 is fixed to the hoisting point of the hoisting frame, and the lower block unit is vertically hoisted and transported to a preset installation position by the hoisting device. The lowering from the water surface above the preset installation position to the preset installation position underwater includes:

[0067] The hoisting frame 5 is fixedly installed on the pre-buried anchor point 211 on the upper part of the lower block unit 21 to obtain the unit to be hoisted;

[0068] Install a GPS measuring instrument on the unit to be hoisted and fix the hoisting equipment on the hoisting point of the hoisting frame;

[0069] The unit to be hoisted is lifted vertically by using the hoisting equipment 6, and is transported to a preset installation position according to the GPS measuring instrument, and is lowered from above the water surface of the preset installation position to the preset installation position underwater.

[0070] An anchoring point is reserved at the top of each block unit, and then the GPS measuring instrument is installed on the unit to be hoisted, and the unit to be hoisted is hoisted by the hoisting equipment 6. A preset installation position is set on the GPS measuring instrument, so according to the GPS measuring instrument, the unit to be hoisted is transported to the preset installation position, and lowered from the water surface above the preset installation position to the preset installation position underwater.

[0071] As a preferred embodiment of the present invention, before vertically lifting the unit to be hoisted by the hoisting device 6 and transporting the unit to be hoisted to the preset installation position according to the GPS measuring instrument, and lowering the unit from the water surface above the preset installation position to the preset installation position underwater, the present invention further includes:

[0072] A positioning buoy is set above the preset installation position.

[0073] Among them, the positioning buoy can be pre-placed above the water surface at the preset installation position using a floating barrel or box, and then the unit to be hoisted can be lifted into place in combination with the positioning of the GPS measuring instrument.

[0074] As a preferred solution of the present invention, in the process of vertically lifting the unit to be hoisted by the hoisting equipment 6, transporting the unit to be hoisted to the preset installation position according to the GPS measuring instrument, and lowering it from the water surface above the preset installation position to the preset installation position underwater,

[0075] When the position displayed by the GPS measuring instrument coincides with the position of the positioning buoy, the preset installation position is determined and the unit to be hoisted is lowered.

[0076] If the two positions do not coincide, the preset installation position needs to be re-determined. In order to better describe the hoisting process of the water intake head, an example is given below:

[0077] The underwater installation of the intake head is performed in collaboration with a 160-ton crane vessel. To facilitate underwater installation, the upper and lower blocks are first numbered. For example, if the intake head is divided into eight corresponding blocks, take the head numbered "South End Lower Structure 1#" (the lower block located at the south end) as an example. This is the heaviest of the eight blocks. The specific steps for lifting this component are as follows: First, the floating crane slowly moves to the water's edge and adjusts the angle to 66°, which is the optimal angle for the floating crane's maximum lifting capacity (a trial lift is performed first, and the component must not be lifted more than 200mm off the ground). After confirming that everything is correct, the floating crane is started and, using a positioning anchor, slowly moves to the leveled area of ​​the South End Lower Structure 1#. Using GPS positioning and measurement, the South End Lower Structure 1# is lifted and slowly lowered, monitoring the process as it descends, ensuring that it is smoothly positioned in the designated position on the design drawings. (Underwater rail guides are installed to facilitate more precise positioning and guidance by the underwater frogman). According to the design drawings and the coordinate parameters provided by the owner, GPS measurement can accurately locate the coordinates of each lifting point of the water head section. At the same time, four buoys can be set on the water surface. The coordinates of each buoy are the coordinates of each lifting point of the water head to increase the accuracy of the water head's underwater installation. The crane ship is anchored according to the designed plane position of the water head. GPS is used to measure and correct the ship's position to ensure that the crane ship's lifting boom is directly above the water head installation area. The crane ship is ready to lift the water head.

[0078] As a preferred solution of the present invention, in the process of vertically lifting the lower block unit to the preset installation position by the lifting equipment, and lowering it from the water surface above the preset installation position to the preset installation position underwater,

[0079] By installing a measuring rod at each lifting point of the lifting frame, the lifting height of each lifting point during the lifting process is measured;

[0080] When the lifting height deviation is greater than a preset deviation threshold, the lifting height of each lifting point is leveled so that the lifting height deviation is less than the preset deviation threshold; wherein the lifting height deviation is the maximum difference between the lifting points during lifting.

[0081] The crane vessel sails to the shore of the water head and anchors, then hooks and lifts. After confirming that the crane vessel is in a safe lifting state, it uses its self-propulsion and external anchor to lift the water head components away from the prefabrication site. During the lifting process, the four vertical lifting points of the water head block unit are observed for height deviation. If the height deviation is greater than 10cm, the unit is leveled by adding lifting rings and re-lifting. If the height deviation is within 10cm, the installation conditions are met. After the installation preparations are ready, the crane vessel slowly lowers the water tank along the positioning buoy. During the lifting process, the construction workers closely observe the position information of the water tank hoisted on the water. If they find the positioning coordinates are offset, they immediately notify the crane vessel to adjust the lifting posture. The water intake head unit component is lifted and lowered to 1m from the bottom of the foundation pit and then stopped. Divers go underwater to check the implantation of the water intake head and install measuring poles on the two lifting points of the water intake head. The surveyors use GPS to accurately locate the installation measuring poles set on the water intake head. The underwater sonar signal simulation technology cooperates with the underwater high-definition camera to control the flatness of the water intake head installation. The crane vessel construction workers control the brown rope pre-installed on the water intake head unit component to adjust it horizontally so that the plane deviation of the four corners of the water intake head is within the design range, and the water head is hoisted and installed in place. According to this procedure, the four structures of the lower layer of the head are installed one by one, and then the four upper head structures are hoisted until the hoisting operation of all the head structures is completed (when hoisting the upper components of the water intake head, in order to ensure smooth fit with the lower components, the connecting plates around the lower part can be extended upward by about 500mm to facilitate guiding into place).

[0082] It can be seen from the above specific embodiments that the water intake head hoisting method of the water intake pump station provided by the present invention adopts the upper and lower block production method on the shore and the underwater assembly and combination method, and uses the grooves between the upper and lower blocks to rivet and fix them with stainless steel connecting plates. Compared with the traditional integral production and hoisting method, it can effectively avoid the arrival of ultra-large hoisting tonnage crane ships and the time and cost of reassembling the ships; and during hoisting, the block units divided by the hoisting frame are used for fixing and protection, which effectively ensures the stability of the concrete structure.

[0083] The above description, with reference to the accompanying drawings, illustrates the method for hoisting the water intake head of a water intake pump station according to the present invention by way of example. However, those skilled in the art will appreciate that various modifications may be made to the method for hoisting the water intake head of a water intake pump station according to the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
