Description

Technical Field

[0001] The invention relates to the technical field of dock construction, and in particular to an automatic tamping and rock drilling integrated machine and a dock construction method. Background Art

[0002] At present, the trend of dock construction is developing in the direction of intelligence, environmental protection and modularization. With the advancement of science and technology, dock construction is increasingly using automated equipment and intelligent management systems to improve construction efficiency and safety. In addition, the improvement of environmental awareness has also promoted the use of more environmentally friendly materials and technologies in dock construction to reduce the impact on the environment. Modular design allows dock components to be prefabricated in the factory and quickly assembled on site, greatly shortening the construction period.

[0003] In this process, tamping machines play a vital role. Through their powerful impact force, tamping machines can effectively compact the dock foundation, improve the bearing capacity and density of the foundation, and ensure the stability and durability of the dock structure. They can not only complete the compaction work quickly and improve construction efficiency, but also adapt to different types of soil and foundation materials. At the same time, they do not generate noise and dust pollution during the compaction process, which meets modern environmental protection requirements.

[0004] However, when the existing rammer is working, the position of the hull needs to be adjusted to adjust the position of the rammer, and adjusting the hull takes a long time, which affects the working efficiency. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art that when a rammer is working in dock construction, the position of the hull needs to be adjusted to adjust the position of the rammer, which takes a long time to adjust the hull and affects the work efficiency, and to provide an automatic rammer and rock drill integrated machine and a dock construction method.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] In a first aspect, the present invention provides an automatic tamping and rock drilling integrated machine, comprising:

[0008] hull;

[0009] A track, wherein the track is arranged along the length direction of the hull;

[0010] A hoisting assembly, the hoisting assembly comprising a base, a traction mechanism and an arm, the base being movable along the length direction of the track, the arm being arranged on the base, the traction mechanism being connected to the arm, and the traction mechanism being used for hoisting a rock hammer or a rammer;

[0011] A winch is connected to the traction mechanism.

[0012] The number of lifting components is determined according to actual conditions.

[0013] The track is arranged along the length direction of the hull, and the length of the track is extended as much as possible, so that the base can have enough adjustment space to avoid moving the hull as much as possible. The base of the lifting assembly can move along the length direction of the track. When compacting the base bed and chiseling the rock mass, the position of the traction mechanism can be adjusted according to the track, and the winch drives the movement of the traction mechanism. Compared with the prior art to adjust the position of the hull, the present device does not need to move the hull, and the position of the traction mechanism can be adjusted by directly adjusting the base along the track, which reduces the time for adjusting the position of the rammer and is conducive to improving the construction efficiency. In addition, during the construction process, multiple lifting assemblies can be arranged as needed, and multiple lifting assemblies are constructed together, which is conducive to improving the construction efficiency. In addition, the traction mechanism is used to lift the rock hammer or rammer, and the hull can also be used for riprap positioning, which is suitable for narrow waters. In addition, the walking step of ramming and rock drilling is fixed, the hammer drop position is uniform, and the ramming point overlap is guaranteed, which avoids the situation of missing chiseling or missing ramming, and is conducive to improving the quality of base bed construction.

[0014] Preferably, it also includes a trolley and a track extension, wherein the track extension is detachably connected to the end of the track, the track extension extends out of the hull, and the trolley can move along the length direction of the track and the track extension. An inclined brace is also provided below the track extension, one end of the inclined brace is connected to the track extension, and the other end is connected to the outer wall of the hull, and the trolley is used to support the hoisting rock hammer or the rammer.

[0015] Because the end of the traction mechanism often protrudes from the hull during construction, a track extension is provided so that the trolley can move within the projection plane of the end of the traction mechanism. The track extension is detachably connected to the end of the track and can be removed or set up as needed. When replacing the rock hammer and rammer, the trolley can transport the material to be replaced to the designated location, and then transport the replaced material to the designated location, which is convenient for improving construction efficiency. A diagonal brace is provided under the track extension to improve the structural stability of the track extension.

[0016] Preferably, a chain is provided at the end of the traction mechanism, and the top surfaces of the rock hammer and the rammer are provided with buckling devices, which can be opened and closed.

[0017] By providing chains and locking devices, it is possible to avoid the rock hammer and rammer from being separated from the lifting assembly during the chiseling or tamping process, thereby improving the safety of the construction process.

[0018] Preferably, the jack hammer and the rammer are both provided with a pressure sensor, and the pressure sensor is used to sense the pressure exerted on the jack hammer or the rammer.

[0019] The pressure sensor is used to sense the pressure on the jack hammer or the rammer. It can be used to determine whether the jack hammer or the rammer has hit the ground empty, thereby avoiding the risk of the trolley overturning.

[0020] In a second aspect, the present invention provides a method for constructing a dock, comprising the following steps:

[0021] S1. Dredging is carried out at the designed location of the wharf;

[0022] S2, construction foundation trench;

[0023] S3. Construction base bed:

[0024] S31, transporting blocks of stone to the designed position of the base bed by using an open barge, and dumping the blocks of stone;

[0025] S32, using the automatic tamping and rock drilling machine as described above, and adjusting the position of the base on the track,

[0026] Compacting the blocks dumped in step S31;

[0027] S33, leveling the blocks compacted in S32 to complete the construction of the base bed;

[0028] S4, installing the dock block to the top surface of the base bed;

[0029] S5. Cast the breast wall to complete the construction of the dock.

[0030] Pier blocks are prefabricated concrete components, which are usually used to construct various structural parts of the pier, such as breast walls, foundation trenches, etc. according to needs.

[0031] This construction method first dredges and constructs the foundation trench, and then constructs the foundation bed. During the construction of the foundation bed, the above-mentioned automatic tamping and rock drilling integrated machine is used for positioning, the open barge transports the blocks and dumps them, and the hull of the same tamping and rock drilling integrated machine is used to tamp the blocks, and then level them to complete the construction of the foundation bed. After that, the dock blocks are installed and the breast wall is poured. The same hull is used for dumping and tamping the blocks, which reduces the interference of the water area, overcomes the problem of narrow construction water area, and is conducive to improving the efficiency of construction.

[0032] Preferably, when constructing the foundation trench in step S2, the silt inside the designed position of the foundation trench is first cleared, and then the soil layer inside the designed position of the foundation trench is excavated. When there is a rock layer in the designed position of the foundation trench, the rock layer is removed by using the rock hammer of the automatic tamping and rock drilling machine.

[0033] Preferably, before clearing the silt inside the designed position of the foundation trench in step S2, a temporary sand bank is set behind the foundation trench.

[0034] Set up temporary sand embankments to avoid siltation inside the foundation trench as much as possible.

[0035] Preferably, the slope ratio of the temporary sand embankment is not greater than 1:3, and the surface of the temporary sand embankment is provided with concrete waste slag and block stone protection.

[0036] Too large a slope ratio will increase the risk of sand bank landslides and further weaken the stability of the sand bank, so the slope ratio of the temporary sand bank should not be greater than 1:3. The surface of the temporary sand bank is provided with concrete slag and stone blocks to prevent the sand bank from being eroded by waves as much as possible.

[0037] Preferably, before installing the dock block in step S4, a positioning frame is provided, the positioning frame and the dock block are both provided on the top surface of the base bed, and the positioning frame is used to assist in installing the dock block.

[0038] Preferably, a working platform is provided on the top of the positioning frame. Before installing the dock block, a reference line is set on the working platform on the top of the positioning frame, and the reference line facilitates the positioning of the dock block.

[0039] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0040] 1. An automatic tamping and rock drilling machine of the present invention comprises: a hull, a track, a hoisting assembly and a winch. The track is arranged along the length direction of the hull, and the length of the track is extended as much as possible, so that the base can have enough adjustment space to avoid moving the hull as much as possible. The base of the hoisting assembly can move along the length direction of the track. When tamping the base bed and drilling the rock mass, the position of the traction mechanism can be adjusted according to the track, and the winch drives the movement of the traction mechanism. Compared with the prior art to adjust the position of the hull, the present device does not need to move the hull, and can directly adjust the position of the traction mechanism by adjusting the base along the track, thereby reducing the time for adjusting the position of the tamping machine and improving the construction efficiency. In addition, during the construction process, multiple hoisting assemblies can be arranged as needed, and multiple hoisting assemblies can be constructed together, which is conducive to improving the construction efficiency. An automatic tamping and rock drilling machine overcomes the shortcomings of the prior art that when the tamping machine in the dock construction is working, the position of the hull needs to be adjusted to adjust the position of the tamping machine, and the adjustment of the hull takes a long time, which affects the work efficiency. In addition, the walking distance of tamping and rock drilling is fixed, the hammer drop position is uniform, and the tamping point overlap is guaranteed, which avoids missed drilling or missed tamping and is beneficial to improving the quality of base bed construction.

[0041] 2. A method for the construction of a dock, which first involves dredging and foundation trench construction, and then the construction of the foundation bed. During the construction of the foundation bed, the above-mentioned automatic tamping and rock drilling integrated machine is used for positioning, and the open-body barge is used to transport the blocks and dump them. The hull of the same tamping and rock drilling integrated machine is used to tamp the blocks, and then level them to complete the construction of the foundation bed. After that, the dock blocks are installed and the breast wall is poured. The same hull is used for dumping and tamping the blocks, which reduces interference in the water area, overcomes the problem of narrow construction waters, and is conducive to improving construction efficiency.

[0067] Example 2

[0068] like Figure 5 As shown, a construction method of a dock comprises the following steps:

[0069] S1. Dredging is carried out at the designed location of the wharf;

[0070] S2, construction foundation trench;

[0071] S3, construction base 10:

[0072] S31, transporting blocks of stone to the designed position of the base bed 10 by using an open barge, and dumping the blocks of stone;

[0073] S32, using the automatic tamping and rock drilling integrated machine described in Example 1, and adjusting the position of the base 301 on the track 2 to tamp the blocks dumped in step S31;

[0074] S33, leveling the blocks compacted in S32 to complete the construction of the base bed 10;

[0075] S4, installing the dock block 11 to the top surface of the base bed 10;

[0076] S5. Cast the breast wall to complete the construction of the dock.

[0077] Before removing the silt inside the designed position of the foundation trench in step S2, a temporary sand bank 12 is set behind the foundation trench and 100m behind the designed position of the front line of the wharf. Figure 8 The slope ratio of the temporary sand bank 12 is not greater than 1:3, and the surface of the temporary sand bank 12 is provided with concrete waste slag and block stone protection.

[0078] First, a certain wharf is set up, and the construction process is as follows:

[0079] Step 1: Dredging construction:

[0080] It is planned to deploy one hopper and one anchor boat. The overall dredging direction is from south to north. Grab boats are considered for construction near slopes or existing structures. The positioning and dredging methods of the hopper are as follows:

[0081] 1) Ship positioning

[0082] The DGPS, or differential global positioning system, is used. The software with data acquisition, data processing and automatic drawing functions is used to process data through a computer, and the outline of the designed dredging section, the edge of the designed trench, the dredging navigation track and real-time navigation data are displayed on the electronic display screen. At the same time, it is connected with the water level telemeter and the drag head depth indicator to display the dredging depth, instantaneous water level, trench cross-section or underwater three-dimensional stereogram in real time.

[0083] 2) Dredging

[0084] The driver gave the "prepare to rake" command, and the rake operator slowly lowered the sludge suction pipe into the water. After the bent pipe was connected to the suction port, the mud pump was started and the low-concentration discharge valve was opened to allow the clean water to be directly discharged from the bottom of the ship. The sludge suction pipe and the rake head were lowered to a certain depth as required by the driver.

[0085] When the dredger is about to reach the dredging position and the driver orders to lower the rake, the rake head is lowered to the mud surface and the pump is increased to normal speed to start dredging. When the instrument indicates that the concentration increases, the loading valve is opened and the low-concentration discharge valve is closed to start loading.

[0086] 3) Operation of ships during construction

[0087] The propellers of the dredger are all remotely controlled. The driver can directly control the operating status of the main engine from the control console and determine the advance and retreat and speed of the dredger by the propeller angle.

[0088] Step 2: Excavation of foundation trench:

[0089] The geological conditions of the foundation trench of this project are mostly silt and silty clay layers, with a small part being weathered rock layers. The dredging bottom elevation is -20m to -22m. After comprehensive consideration, this project uses grab dredgers to excavate the foundation trench. If the excavation reaches a rock layer that the grab boat cannot construct, the rock drilling process is used. For the junction area between the new and old docks, only grab boats can be used for dredging and foundation trench excavation. According to diving exploration, there are small areas of scattered rocks and silt bags at the junction of the new and old docks. Grab boats are used to remove the rocks, and silt bags are dredged with silt pumps. Divers clean the aquatic plants and animals on the surface of the blocks. Before excavating the foundation trench, the two blocks on the bottom layer of the original dock are hoisted in advance and reinstalled after the foundation trench is leveled and compacted.

[0090] 1. The foundation trench is excavated by grab bucket from south to north, in sections, layers and strips. The overlap between strips during construction is determined according to the actual situation;

[0091] 2. Carry out step-by-step excavation according to the designed slope and the principle of "lower overshoot and upper undershoot, balance between overshoot and undershoot" to meet the designed slope requirements and effectively control the excavation volume of the foundation pit without leaving shallow points;

[0092] 3. When the designed elevation is still not reached after excavation to the rock layer, a heavy grab bucket is used to excavate the strongly weathered rock layer until excavation is no longer possible;

[0093] 4. When the foundation trench can no longer be excavated, a rock hammer or rock drill rod is used for rock drilling.

[0094] Step 3: Construction of base bed 10:

[0095] 1. Base bed 10 riprap:

[0096] Use land dump trucks to transport stones to the shipping terminal, load them onto open barges, and then transport them to the site for positioning and dumping. Dumping is carried out from south to north. A flat barge equipped with a GPS positioning system is used to position the dumping. A tugboat is used to coordinate with the flat barge to move the ship for positioning. Three open barges are equipped for dumping stones. For supplementary dumping, consider dumping at fixed points on the upper barge of the excavator. The dumping of the subgrade 10 stones should be closely coordinated with the excavation of the foundation trench to minimize the exposure time of the foundation trench. The intensity and progress of the dumping are arranged according to the progress of the foundation trench excavation. The dumping of the subgrade 10 stones and the dredging construction are staggered by a distance corresponding to a construction section. According to typical construction tests, a certain amount of tamping is reserved for the dumping of the subgrade 10 stones.

[0097] 2. Compacting the base bed 10:

[0098] The same flat barge is used for tamping the subgrade 10 and riprap. The barge is equipped with a slideway system, rammer and rammer frame. The height of the rammer lifting is determined based on typical construction tests.

[0099] Before compaction, the riprap surface layer should be properly leveled, and the local height difference should not be greater than 20cm. The compaction adopts half-tamp in the longitudinal and transverse directions, with one initial tamping and one re-tamping, and 4 tampings each time, to prevent the unit part of the base bed 10 from bulging and missing tamping. During the compaction process, pay attention to the influence of water flow direction, speed and tidal changes on the position of the tamping hammer, and adjust the position of the tamping hammer in time. The base bed 10 should be compacted in layers and sections, and the thickness of each layer is roughly equal, generally not more than 1.5m, and the overlap length of the section compaction is not less than 2m.

[0100] 3. Leveling of base bed 10:

[0101] After the base bed 10 is compacted, it should be leveled as soon as possible to avoid excessive siltation. The hydraulic underwater leveling machine is a hollow steel pipe structure, which can pressurize water through the automatic water inlet. It sinks when the pressure exceeds the buoyancy. After the leveling machine is in place and enters the water, seawater enters the hollow steel pipe through the automatic water inlet, and the leveling machine sinks steadily and slowly. The initial positioning is carried out through four floating drums, and then the material distribution pipe is used for precise measurement and positioning (position and elevation). The hydraulic transmission device is used to drive the material distribution pipe that can move along the track to move longitudinally and transversely for material distribution and leveling operations. After one leveling work position is completed, the leveling machine is moved to the next work position with the cooperation of the excavator.

[0102] Step 4: Shipment and installation of dock block 11

[0103] 1. Construct a temporary wharf and install the positioning frame 9, such as Figure 6 As shown;

[0104] 2. Transfer the wharf block 11 from the prefabrication yard storage area to a flatbed truck, and then transfer it from the flatbed truck to a transport ship;

[0105] 3. Install the dock block 11. After installation, Figure 7 As shown:

[0106] a. After the flat barge (installation ship) is anchored and positioned, the hull is moved by twisting the anchor cable on the ship so that the installation ship is located near the water surface of the installation base bed 10.

[0107] b. The installation vessel is roughly positioned on the previously leveled positioning frame 9 through the GPS system. The three positioning frames 9 are arranged in an L shape, with the positioning frame 9 extending three angle steels placed at the southwest corner of the installation section, and the other two positioning frames 9 are vertically placed on the north and east sides of the L. The positioning frame 9 is adjusted through the GPS set on the platform to ensure that the positioning frame 9 is erected on the foundation as required.

[0108] c. After the installation of the positioning frame 9 is completed, the 400t crawler crane on the installation ship lifts the block and slowly sinks it into the water. The underwater diver communicates with the command signalman on the ship in real time through the underwater telephone, and the block is roughly positioned and launched into the water according to the block installation position determined by the positioning frame 9. There are multiple water holes on the block. During the sinking process, the sinking speed must match the speed of water entering the block box. It must not be sunk too fast to cause the block to tilt due to buoyancy. The block must be kept vertical and stable during the sinking process, and it must not shake violently.

[0109] d. After the underwater rough positioning of the block is completed, the diver cooperates to check the position of the block underwater. The diver directs the 400t crawler crane to slowly lower the block. When the distance between the bottom of the block and the base bed 10 is about 20cm, the diver uses a ruler (with a horizontal bubble) to directly read the distance between the actual position of the block and the position to be installed, and feeds it back to the captain to direct the mobile boom to adjust the position, so as to accurately position the block until it reaches the deviation range required by the technical specifications. When the position of the block meets the requirements, the diver will re-measure the position of the block. After meeting the requirements, the crane will place the block on the base bed 10, and the diver will untie the lifting gear;

[0110] e. When installing the first block, if the installation accuracy cannot be guaranteed because there is no support, you can roughly install the first block first. After the second block is accurately installed, use the second block as support and reinstall the first block to ensure the installation accuracy of the first block.

[0111] 4. Pre-press the block;

[0112] 5. Arrange the block stone prism, inverted filter layer and geotextile behind the block;

[0113] Step 5: Track beam after construction

[0114] Step 6: Casting the dock breast wall:

[0115] 1. The installed blocks must be pre-pressed and accepted before the breast wall construction can be carried out; the block pre-pressing adopts prefabricated small blocks for loading, and the width range and amount of the ballast are strictly in accordance with the load requirements and relevant drawings provided by the owner. The crawler crane is used to load and unload the pre-pressed blocks; according to the requirements of the technical specifications, the pre-pressing of the pile load shall last at least 21 days, and it can only be ended when the settlement value of the last 14 days of continuous observation is less than 5mm and lasts for no less than 5 days;

[0116] 2. Before the breast wall is constructed, the top surface of the blocks should be roughened and cleaned;

[0117] 3. After the steel bars are cut and processed in the steel bar processing yard, they are transported to the site by flatbed trucks and tied directly on the blocks by workers. Steel bar protective layer pads are set on the bottom and sides of the steel bars, and the plane position and elevation of the embedded parts are measured and released;
