Description

Technical Field

[0001] This utility model relates to the field of wharf engineering technology, and in particular to a ramp pier formwork system for a breakwater wharf. Background Technology

[0002] With the rapid development of the water transport industry, more and more wharf structures are being built in various ports to facilitate ship berthing, cargo loading and unloading, and transportation. During the design and construction of wharves, fire protection needs to be considered so that timely fire rescue work can be carried out when a fire occurs on the wharf or on a ship. In the case of limited shoreline resources, in order to reduce the length of shoreline used, the wharf structure often adopts the jetty wharf. The jetty wharf refers to a wharf that extends from the land shore into the water. Ships can be moored on both sides and at the ends of the jetty. It has the advantages of compact layout and centralized management.

[0003] Pier-type wharf structures typically connect approach bridges to wharf platforms, with berths for ships along the platform. When a fire breaks out on a ship, wharf, or adjacent building, fireboats are usually used for rescue operations. Fireboats have strong water supply capabilities, enabling them to quickly suppress and extinguish fires. However, fireboats are primarily used for firefighting, and their function is relatively singular. When fires break out in the cabins or adjacent buildings, trapping people, fireboats cannot approach the ship and cannot carry out effective rescue operations. Fireboats equipped with fire trucks and other firefighting equipment can provide flexible rescue support in different scenarios (e.g., fireboats equipped with ladder trucks can perform both firefighting and personnel and material rescue operations), improving the maritime rescue capabilities of fireboats.

[0004] Existing breakwater-type wharf structures only consider the berthing of fireboats, neglecting the loading of fire trucks. Due to factors such as the wharf platform structure and the fireboat's own structure, fire trucks cannot be loaded onto the fireboats after they are moored at the wharf berth. Therefore, a platform is needed to allow fire trucks to board for rescue operations. In the design and construction of this platform, the structural formwork system directly affects the construction difficulty, concrete pouring quality, and platform surface appearance. How to design the formwork system structure is a crucial issue in platform formwork design. Furthermore, during platform design and construction, as the platform gradually transitions from above water to underwater, the formwork will be installed in the water during the construction of the underwater portion of the platform structure. Water inevitably seeps into the space enclosed by the formwork, affecting the concrete pouring quality. Ensuring the construction quality of the underwater portion of the platform is also a critical issue in platform formwork design. Utility Model Content

[0005] One of the objectives of this utility model is, at least, to provide a formwork system for ramp piers of breakwater wharves, addressing the problems existing in the prior art. This formwork system ensures the smooth construction of ramp piers, reduces the difficulty of ramp pier construction, and minimizes water accumulation in the space enclosed by the formwork when constructing the underwater portion of the ramp pier, thus ensuring smooth concrete pouring and guaranteeing the surface appearance quality of the ramp pier after construction.

[0006] To achieve the above objectives, the technical solution adopted by this utility model includes the following aspects.

[0007] A formwork system for a ramp pier of a breakwater wharf includes three formwork sections connected sequentially along the length of the ramp: a first pier section formwork, a second pier section formwork, and a third pier section formwork. The third pier section formwork includes a bottom formwork, side formworks, and a top formwork. The bottom formwork, side formworks, and top formwork, together with the second pier section, form a concrete pouring space for the third pier section. The outer support side of the top formwork is provided with a groove that connects to the panel of the top formwork. The top of the groove is open, and the bottom is closed.

[0008] Preferably, the clamping groove is provided along the height direction of the three-sealing head mold of the pier section, the bottom of the clamping groove extends out of the bottom of the three-sealing head mold of the pier section, and the bottom of the clamping groove and the side of the clamping groove near the panel of the three-sealing head mold of the pier section are both sealed by a sealing plate.

[0009] Preferably, the overall shape of the clamping groove is a prism structure. The clamping groove is welded to the three-sealing head mold panel of the pier section to form an integral structure. The clamping groove is reinforced in the height direction. Multiple reinforcing ribs are also evenly arranged in the height direction of the clamping groove. Each reinforcing rib is arranged along the circumference of the clamping groove. The reinforcing ribs and reinforcing rods are all arranged on the outer side of the clamping groove.

[0010] Preferably, the external support of the pier section three-sealed head mold includes horizontal ribs and back bars. Multiple horizontal ribs are evenly arranged along the height direction of the pier section three-sealed head mold panel, and multiple back bars are evenly arranged along the length direction of the pier section three-sealed head mold panel. The clamping groove is arranged between two adjacent back bars.

[0011] Preferably, the bottom of the three-sealed head mold panel of the pier section is flat and the top is inclined.

[0012] Preferably, the three-sided formwork of the pier section includes a first three-sided formwork and a second three-sided formwork, the height of the first three-sided formwork is lower than the height of the second three-sided formwork; the first three-sided formwork is assembled from multiple side formwork units in the length direction, and the second three-sided formwork is assembled from multiple side formwork units in the length direction.

[0013] Preferably, the outer supports of both side mold unit one and side mold unit two include horizontal ribs and back bars. The bottom of the back bar of side mold unit one extends out of the bottom of the panel of side mold unit one. The top of the panel of side mold unit one is provided with a head groove along the length of the panel. The top of the back bar of side mold unit one is connected to the bottom of the head groove. The top surface of the head groove is a plane. The top and bottom of the back bar of side mold unit two extend out of the panel of side mold unit two, respectively.

[0014] Preferably, the overall shape of the bottom formwork of the pier section three is rectangular. The bottom formwork of the pier section three is assembled from multiple bottom formwork units along its length. At the position of the pier column of the pier section three along its length, the bottom formwork unit includes a bottom formwork unit one and a bottom formwork unit two arranged opposite to each other. The bottom formwork unit one has an inwardly recessed arc opening one, and the bottom formwork unit two has an inwardly recessed arc opening two. The diameter of the arc opening one and the diameter of the arc opening two are the same, and the diameter of the arc opening one is larger than the diameter of the pier column of the pier section three.

[0015] Preferably, the outer support of the bottom mold unit includes horizontal ribs and vertical stiffeners, with multiple horizontal ribs evenly arranged along the width direction of the bottom mold unit, and one or more vertical stiffeners connecting adjacent horizontal ribs.

[0016] Preferably, the length of the top opening of the clamping groove is 500~600mm and the width is 500~600mm.

[0017] In summary, by adopting the above technical solution, this utility model has at least the following beneficial effects:

[0018] The formwork system for the ramp piers of this utility model includes three formwork sections: pier section one, pier section two, and pier section three. The pier section three formwork includes a bottom formwork, side formwork, and end formwork. By setting a groove on the outer support side of the end formwork, which connects to the end formwork panel, it is easy to place or remove a water pump from the groove, preventing damage to the water pump. This avoids interference from the steel reinforcement and internal supports within the space enclosed by the pier section three formwork. After the water pump removes the accumulated water within the space enclosed by the pier section three formwork, the quality of concrete pouring is improved, ensuring the surface appearance quality of the ramp pier after construction.

[0019] By extending the bottom of the grooving groove beyond the bottom of the pier section's three-part formwork, a height difference exists between the bottom of the grooving groove and the bottom formwork of the pier section after the three-part formwork is installed. When water accumulates in the space enclosed by the three-part formwork, the water can flow along the bottom formwork into the grooving groove of the three-part formwork and then be pumped out. Directly placing the pump on the bottom formwork of the pier section cannot remove all the water in the space enclosed by the three-part formwork; some water will remain in the space. Compared to directly placing the pump on the bottom formwork of the pier section, the structure of extending the bottom of the grooving groove beyond the bottom of the three-part formwork can prevent water accumulation on the surface of the bottom formwork and ensure the quality of concrete pouring.

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, so that the purpose, technical solution and advantages of the present invention will be clearer. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example

[0030] refer to Figure 1 , Figure 2 The exemplary embodiment of this utility model of the pier-type wharf structure includes a wharf 3, which is connected to the shore by an approach bridge 2. A steel temporary bridge 4 parallel to the approach bridge 2 is provided on one side of the approach bridge 2. The steel temporary bridge 4 is spaced apart from the approach bridge 2 and extends towards the front edge 31 of the wharf. A ramp 1 is provided on the other side of the approach bridge 2 and is connected to the approach bridge 2. The ramp 1 extends along the length of the approach bridge 2 to the wharf 3. The top elevation of the front edge of the ramp 1 is lower than the top elevation of the wharf 3, and the difference between the two is 2.5~3.5m.

[0031] By setting up a ramp 1 on the side opposite to the approach bridge 2 and the temporary steel bridge 4, when a thousand-ton workboat (such as a workboat with a 1200-ton pier) is moored on one side of the wharf 3, the workboat is simultaneously moored at the edge of the ramp 1. Fire trucks can enter the ramp 1 from the approach bridge 2, board the workboat via the ramp 1, and cooperate with the workboat 5 to carry out fire rescue work. Since the ramp 1 is set up on one side of the approach bridge 2 and extends to the wharf 3, the ramp 1 can adapt to different water levels. At different water levels, when the workboat is moored at the berth of the wharf 3, fire trucks can enter the workboat via the ramp 1 to carry out rescue work. When constructing a breakwater wharf structure, the temporary steel bridge 4 can facilitate the transportation of materials.

[0032] Ramp 1 comprises three sections: pier section 11, pier section 2, and pier section 3, which are connected sequentially along the length of ramp 1 to form a single structure. The bottom elevation of pier section 11 is higher than that of pier section 2, and the bottom elevation of pier section 2 is higher than that of pier section 3. Both the bottom and top of pier section 11 have slopes, and the slope direction of the bottom and top is... Similarly, the bottom of pier section 2 (12) is flat, while the top is sloped; the bottom of pier section 3 (13) is flat, while the top is sloped. Pier section 1 (11) slopes towards pier section 2 (12) (pier section 1 (11) slopes downwards towards pier section 2 (12)), and the top of pier section 2 (12) slopes towards pier section 3 (13). Pier section 1 (11) connects to approach bridge 2, allowing fire trucks to smoothly enter ramp 1 from approach bridge 2, and proceed from pier section 2 (12) to pier section 3 (13). In three directions, the overall thickness of pier section 2 12 gradually decreases. By connecting pier section 3 13 at the edge of pier section 2 12, the thickness of pier section 3 13 is thicker than the edge thickness of pier section 2 12, which can increase the structural strength of the edge of ramp 1. On the one hand, it can disperse the impact energy of surging waves and prevent local structural damage to ramp 1. On the other hand, when the work boat is docked at the berth of wharf 3, there will be a certain distance between the work boat and the front edge of ramp 1. When fire trucks board the ship via ramp 1, a jumping phenomenon will occur at the distance between ramp 1 and the work boat. The thickened pier section 3 13 of ramp 1 can resist the impact energy generated by the jumping of fire trucks and prevent structural damage to ramp 1. When the distance between the work boat and the front edge of ramp 1 is large and fire trucks cannot board the ship directly, a ramp can be erected between ramp 1 and the work boat to allow fire trucks to board the ship smoothly.

[0033] The top and bottom slopes of pier section 11 are both 2% to 3%, while the top slope of pier section 212 is 5% to 7%, allowing fire trucks to start and stop smoothly on ramp 1 and ascend and descend the slope, facilitating the loading of fire trucks onto the ship. In practice, for example, the bottom elevation of pier section 11 is reduced from +3.6m to +3.2m at a slope ratio of 2.6%, and the top elevation is reduced from +5.1m to +4.7m at a slope ratio of 2.6%; the bottom elevation of pier section 212 is +1.2m, and the top elevation is reduced from +4.7m to +2.6m at a slope ratio of 5.6%; the bottom elevation of pier section 313 is +0m, and the top elevation is reduced from +2.6m to +2.2m. Furthermore, the ramp is at least 50m long (preferably 56m) and at least 14m wide, with the pier section 11 being 15m long. The ramp, serving as a platform support, can meet various needs such as vehicle turning, boarding and alighting from ships, and pedestrian and cargo loading and unloading. The approach bridge 2 also has a slope, extending from the shore side towards the wharf 3 at a gradient of 2% to 3%. Preferably, the approach bridge decreases from a shore elevation of +6.5m to +4.7m on the water side, with a thickness of 1.5m, a length of 114m, and a width of 9m. The wharf berth is 140m long, with a top elevation of +4.7m, a thickness of 1.5m, and a width of 9m. Example

[0034] The formwork system for the ramp piers of the breakwater-type wharf in this embodiment is used for the ramp pier structure in Embodiment 1. The formwork system includes three sections of pier section 1, pier section 2, and pier section 3, connected sequentially along the length of ramp 1. Pier section 1 includes a bottom formwork, a side formwork, and an end formwork. Pier section 2 includes a bottom formwork, a side formwork, and an end formwork. Both the bottom formwork of pier section 1 and pier section 2 are made of plywood. The other formwork for pier section 1 and pier section 2 is made of steel. Pier section 3 is also made of steel. (See reference...) Figure 3 , Figure 4 The three formwork sections of the pier section include the bottom formwork 6, the side formworks, and the end formwork 9. The outer support side of the end formwork 9 is provided with a groove 91, which connects to the panel of the end formwork 9. The top of the groove 91 is open and the bottom is closed.

[0035] When the formwork of the third pier section encloses the concrete pouring space of the third pier section 13, seawater will seep into the space enclosed by the formwork of the third pier section 13 because the bottom formwork 6 of the third pier section 13 is located in water, and the side formwork and the end formwork 9 of the third pier section 13 are also partially located in water. It is necessary to pump out the water in the space enclosed by the formwork of the third pier section 13 to ensure the subsequent concrete pouring quality of the third pier section 13. The space enclosed by the formwork of the third pier section 13 contains steel reinforcement skeletons, internal supports and other structures, which will affect the placement and removal of the water pump. After setting the clamping groove 91 on the outer support side of the end formwork 9 of the third pier section 13, the water pump can be placed directly in the clamping groove 91. The placement and removal of the water pump will not be affected by the steel reinforcement skeleton, internal supports and other structures, which is conducive to the smooth removal of seawater. After the seawater is pumped out, the water pump can be removed from the clamping groove 91 by water, preventing damage to the water pump.

[0036] The bottom of the panel of the third sealing head formwork 9 of the pier section is flat, and the top is sloped. Setting the top sloped ensures the inclination of the top of the third sealing head formwork 13 after construction; (Reference) Figure 5 The pier section's three-sealed head mold 9 has vertical flanges 101 on both sides and a horizontal flange 100 at the bottom for connection with adjacent molds. The external support of the pier section's three-sealed head mold 9 includes horizontal ribs 102 and back bars 103. Multiple horizontal ribs 102 are evenly arranged along the height direction of the pier section's three-sealed head mold 9 panel, and multiple back bars 103 (using back-to-back channel steel, connected by connecting channel steel to create spacing between them) are evenly arranged along the length direction of the pier section's three-sealed head mold 9 panel. A rib plate 104 (rectangular) is provided between the horizontal ribs 102 and the horizontal flanges 100 at the bottom of the pier section's three-sealed head mold 9 panel. The vertical flanges 101 are made of angle steel, and multiple rib plates 104 (triangular) are evenly arranged along the height direction of the vertical flanges 101. When the pier section's three-sealed head mold 9 is connected to adjacent molds, it can ensure the structural strength of the connection part of the pier section's three-sealed head mold 9 and prevent structural deformation of the connection part of the pier section's three-sealed head mold 9.

[0037] The clamping groove 91 is set between two adjacent back bars 103, which not only ensures the structural strength of the three-sealed head mold 9 of the pier section, but also meets the requirements of dewatering. The clamping groove 91 has an overall prism structure and is welded to the panel of the three-sealed head mold 9 of the pier section to form an integral structure. The panel of the three-sealed head mold 9 of the pier section has a connecting opening 90 at the connection position of the clamping groove 91. The clamping groove 91 is welded at the position of the connecting opening 90. A reinforcing rod 92 is set in the height direction of the clamping groove 91. Multiple reinforcing ribs 93 are also evenly arranged in the height direction of the clamping groove 91. Each reinforcing rib 93 is arranged around the circumference of the clamping groove 91. The reinforcing ribs 93 and the reinforcing rods 92 are all set on the outer surface of the clamping groove 91. The reinforcing ribs 93 and the reinforcing rods 92 can improve the structural strength of the clamping groove 91 and prevent the structure of the clamping groove 91 from deforming.

[0038] The clamping groove 91 is set along the height direction of the three-sealing head mold 9 of the pier section, and the bottom of the clamping groove 91 extends beyond the bottom of the three-sealing head mold 9 of the pier section (reference). Figure 5 , Figure 6 There is a certain distance (300~400mm) between the two; when the bottom of the clamping groove 91 extends beyond the bottom of the pier section three-sealing head mold 9, the bottom of the clamping groove 91 and the side of the clamping groove 91 near the panel of the pier section three-sealing head mold 9 are both sealed by the sealing plate 94, so that the part of the clamping groove 91 extending beyond the pier section three-sealing head mold 9 and the pier section three-sealing head mold 9 form a closed space to prevent seawater from seeping into the clamping groove 91 from the gap between the clamping groove 91 and the pier section three-sealing head mold 9; since the bottom of the clamping groove 91 extends beyond the bottom of the pier section three-sealing head mold 9, after the pier section three-form template is installed, there is a distance between the bottom of the clamping groove 91 and the pier section three-bottom mold 6, when the space enclosed by the pier section three-form template is... When there is water accumulation inside, the water can flow along the bottom formwork 6 of the pier section into the groove 91 of the top formwork 9 of the pier section, and then be pumped out by a water pump. If the water pump is placed directly on the bottom formwork 6 of the pier section to pump water, the pump needs to be submerged in water to operate. When the water level drops below the pump inlet, the pump will stop running due to idling or air intake, and cannot completely pump out the water in the space enclosed by the bottom formwork 6 of the pier section; some water will remain in the space. Compared to directly placing the water pump on the bottom formwork 6 of the pier section, the structure of the groove 91 extending beyond the bottom of the top formwork 9 of the pier section prevents water accumulation on the surface of the bottom formwork 6 of the pier section, ensuring the quality of concrete pouring. The dimensions of the groove 91 meet the requirements for water pump placement. Furthermore, the length and width of the top opening of the groove 91 are 500-600mm.

[0039] During the use of the three-sealed head formwork for the pier section, after dewatering and before concrete pouring, a rectangular baffle can be placed in the clamping groove 91. Foam rubber sheets are then attached to the baffle at the connection opening 90 corresponding to the three-sealed head formwork 9 of the pier section, sealing the connection opening 90. A support rod is then placed in the clamping groove 91, supporting the baffle between the baffle and the groove wall, ensuring the stability of the baffle installation. This prevents concrete from entering the clamping groove through the connection opening 90 during the concrete pouring process of the three-sealed head formwork for the pier section, ensuring the construction quality of the three-sealed head formwork and reducing the difficulty of subsequent formwork removal.

[0040] refer to Figure 4 The three-sided formwork of the pier section includes pier section three-sided formwork 7 and pier section three-sided formwork 8. The overall shape of pier section three-sided formwork 7 and pier section three-sided formwork 8 are both rectangular. The height of pier section three-sided formwork 7 is lower than the height of pier section three-sided formwork 8. The length direction of pier section three-sided formwork 7 ( Figure 4 (Front-back direction) is assembled from multiple side formwork units, and the three side formwork units of the pier section are 8 units long ( Figure 4 (Front-back direction) It is assembled from multiple side mold units. Both side mold unit one and side mold unit two are rectangular structures. The external supports of side mold unit one and side mold unit two include transverse ribs 102 and back bars 103. (See reference) Figure 8 The bottom of the back bar 103 of side formwork unit one extends out of the bottom of the panel of side formwork unit one. A head groove 105 is provided at the top of the panel of side formwork unit one along the length of the panel. The top of the back bar 103 connects to the bottom of the head groove 105. The top surface of the head groove 105 is flat. When side formwork unit one 7 of pier section three is installed, the top surface of the head groove 105 at the top of the panel of side formwork unit one can abut against the bottom surface of pier section two 12, ensuring smooth concrete pouring for pier section three 13. A horizontal flange 100 is provided at the bottom of the panel of side formwork unit one, and vertical flanges 101 (flat steel) are provided on both sides. The horizontal flange 100 and the horizontal rib 102 are connected by multiple stiffening plates 104. (Reference) Figure 3 The top and bottom of the back brace 103 of side formwork unit two extend out of the side formwork unit two panel, respectively. When installing side formwork unit one 7 and side formwork unit two 8 of pier section three, the bottom of the back brace 103 of side formwork unit one and side formwork unit two can be pulled together by tie rod 10, which further improves the stability of the installation of the pier section three formwork. Since the height of side formwork unit one 7 of pier section three is lower than the height of side formwork unit two 8 of pier section three, the top of side formwork unit one 7 and the top of side formwork unit two 8 of pier section three cannot be connected by tie rod. The top of the back brace 103 of side formwork unit two and the steel reinforcement of pier section three 13 are connected (see reference). Figure 4 (The steel bars are not shown in the figure), which can ensure the stability of the installation of the three side formworks of the pier section and the overall stability of the installation of the three formworks of the pier section; the bottom of the panel of the second side formwork unit is provided with a horizontal flange 100, and the two sides are respectively provided with vertical flanges 101 (flat steel). The horizontal flange 100 and the horizontal rib 102 are connected by multiple stiffening plates 104.

[0041] The overall shape of the bottom formwork 6 of the pier section is rectangular, and the length direction of the bottom formwork 6 of the pier section is ( Figure 4 Forward and backward directions Figure 7 (In the left-right direction) It is assembled from multiple bottom formwork units. The length of each bottom formwork unit can be adjusted according to the actual situation. In the length direction of the bottom formwork 6 of the third pier section, corresponding to the position of the pier column 5 of the third pier section 13, the bottom formwork unit includes bottom formwork unit 1 61 and bottom formwork unit 2 62 arranged opposite to each other. Bottom formwork unit 1 61 has an inwardly recessed arc opening 1 610, and bottom formwork unit 2 has an inwardly recessed arc opening 2 620. The diameter of arc opening 1 610 and arc opening 2 620 are the same, and the diameter of arc opening 1 610 is slightly larger than that of the third pier section 13. The diameter of pier 5 (for example, the diameter of arc opening one is 5-8mm larger than the diameter of pier 5 in pier section three) is formed when bottom formwork unit one 61 and bottom formwork unit two 62 are assembled into a bottom formwork unit. Arc opening one 610 and arc opening two 620 form a circular opening. The diameter of the circular opening is slightly larger than the diameter of pier 5 in pier section three 13, so that pier 5 can pass through the circular opening of the bottom formwork unit, thereby meeting the construction requirements of pier section three 13. The gap between the circular opening of the bottom formwork unit and pier 5 can be sealed with rubber grout-stopping strips to prevent grout leakage during concrete pouring.

[0042] The external support of the bottom formwork unit includes horizontal ribs 102 and vertical stiffening plates 106, with multiple horizontal ribs 102 extending along the width direction of the bottom formwork unit. Figure 7 The bottom formwork units are evenly spaced in the vertical direction, with one or more vertical stiffening plates 106 connecting adjacent transverse ribs 102 to improve the structural strength of the bottom formwork unit. Horizontal flanges 100 are provided along the length and width of the bottom formwork unit's edge to connect adjacent formwork units. The material of the horizontal flanges 100 is selected based on actual usage. For example, for the bottom formwork units on both sides of the third bottom formwork 6 of the pier section, the horizontal flanges 100 are all made of angle steel with triangular stiffening plates. For the bottom formwork unit in the middle section, the horizontal flanges 100 along the length direction are made of angle steel with triangular stiffening plates (the structure is referenced). Figure 5 The vertical flange structure in the middle, and the horizontal flange 100 in the width direction are made of flat steel.

[0043] The above description is merely a detailed illustration of specific embodiments of this utility model, and not a limitation thereof. Various substitutions, modifications, and improvements made by those skilled in the art without departing from the principles and scope of this utility model should be included within the protection scope of this utility model.
