Description

Long-distance double-track double-bucket truss type diker

Technical Field

The utility model relates to a mud flat operation device, concretely relates to long-distance double track twin-bucket truss type diker.

Background

With the acceleration of industrialization and urbanization, the demand of construction land in coastal areas is increased dramatically, sand and stones required by backfilling are gradually reduced, beach resources are reasonably developed and utilized, ocean beach sludge is used as a backfilling material, the method is an important way for solving the problem of shortage of the construction land material resources, protecting the beach and reducing stone exploitation, and is an effective measure for promoting the linkage of land-sea economy and the like. The tidal flat of the utility model refers to the wet immersion zone between the high tide level and the low tide level of the coastal high tide, also called as the intertidal zone. With the development of coastal economic development areas, various civil engineering projects are indispensible in coastal beach areas, and it is more common to fill earthwork in sea tide areas. The construction of the beach earthwork is characterized by large engineering quantity, complex construction conditions and the influence of sea tide on the construction. Due to the action of tides, some beaches are sometimes submerged and sometimes exposed out of the water, the upper parts of some beaches are often exposed out of the water, and the lower parts of some beaches are often submerged. When earthwork construction is carried out in a sea tide affected area, construction difficulties such as sea tide fluctuation, wind wave flow velocity, sludge adhesion and the like can be encountered, and the existing earthwork equipment and method cannot be applied.

The existing land earthwork machinery, such as a scraper, a loader, a transporter and the like, can be submerged by water when the tide rises, can sink in a mud beach when being laid and smeared, is difficult to pull out, and can only be constructed on land. The existing overwater earthwork machinery, such as a dredger, a suction dredger, a hopper barge and the like, cannot move when being laid and painted after getting damp and can only be constructed on the water. A large number of coastal earthwork projects have intertidal zone construction which is not performed under land machinery and on water machinery. Moreover, the soft clay in the mudflat has the characteristics of fine particles, strong cementing power and large water content. The existing earthwork machinery can not overcome various difficulties in soft clay construction. Therefore, a large number of mudflat projects adopt 'man-sea battles', work is hard, work efficiency is extremely low, and progress is slow. At present, no perfect construction equipment and method exist, a large number of mudflat projects are 'untimely and applicable', the work efficiency is low, and the progress is slow. In the dam construction work, a large amount of closed air earthwork is required while the stone is piled. Mud pumps and cutter suction dredger provide too high water content of soil, cannot be piled up and cannot be firmly stood, and the mud pumps and the cutter suction dredger cannot be used for building dikes.

The tidal marsh mud is taken as a gas-tight material, the material taking part must be far away from the built seawall, otherwise the built seawall can be settled, even the arc is slipped and collapsed, and serious safety accidents are caused. At present, the carrying distance of the diker used in China is mostly between 80m and 120m, the section of a truss girder is small, and only one track and one grab bucket are generally installed. Due to the small distance, the diker which is mature in use must carry out secondary dumping of the daub. Two methods can be used: one method is to use two truss type diker for relay filling, and the scheme needs two common truss type dikers, so that a lot of inconvenience is brought to the construction procedure and the logistics guarantee; the other method is intermittent filling by using a truss type diker. Namely, a mud storage field is established in the range of the transport distance, and then the mud is transported from the mud storage field to the position close to the dike. However, the construction of a mud storage yard is not easy. The reason is that according to the construction progress and the consideration of safety, the construction of closed air soil must be carried out before the closure of the seawall plugging opening, and the mud storage field is necessarily influenced by the seawater tide. According to the geological condition of the project, the upper layer of the sea coating is mostly of the floating mud and flowing mud property, and reinforcement and enclosure measures need to be taken for a mud storage field. In short, both methods result in the loss of daub and low efficiency, and the strengthening and protecting measures are difficult to implement in the shoals, which will seriously increase the engineering cost if they can be implemented.

Adopt a method that long-distance double track twin-bucket truss type diker built the dike, including following step:

s1, firstly measuring and determining the position of the mud collecting field and the clear base range

The closed earthwork material field is arranged in the enclosed area, is parallel to the seawall and is away from the inner slope toe of the seawall by 150 m. The measurement is mainly to determine the position of a mud-mining field and the clear base range. The engineering adopts a total station instrument for lofting, takes a long bamboo pole with the length of 3.0m as a sideline pile, and inserts the coating mud as deep as possible during pile setting to prevent the damage of tidal water.

S2, removing sundries in the mud collecting field according to the range of the measuring result

And (4) cleaning the offshore area from a remote place to the sea wall by adopting a steel wire rope iron dragging chain mode according to the range determined by measurement, transporting the cleaned unqualified materials such as tree roots, sundries and the like out of the construction area, and strictly forbidding the unqualified materials to be used for engineering construction.

And S3, adopting the long-distance double-track double-bucket truss type diker to start operation, collecting the shoal mud from the mud collection field, and transporting the shoal mud to the diking position.

After the embankment machine is assembled, firstly, a back shovel is used for fixing the shore anchor to the position about 200m in front of the advancing direction, the three sea anchors are lifted, and the advancing anchor winch is started to drag the whole truss forwards. The single-side anchor winch can be started to adjust the advancing direction in dragging, the sea anchor is thrown down after the sea anchor reaches a designated position, the guide rope is tensioned, the anchor winch is stopped, and operation can be started at the moment.

S4, setting a settling plate

The key of the construction of the air-tight earthwork is to prevent landslide, once the landslide is generated, the treatment is very difficult, and the quality, the construction period, the engineering safety and the like are greatly influenced, so the control of the loading speed is the key of the quality control of the air-tight earthwork construction. According to the prior construction practice and the control condition of the construction project, construction and loading are controlled in the engineering strictly according to the design of construction drawings and the related technical requirements of bidding documents, quality safety control is carried out, construction settlement observation is enhanced, and the actually measured data is used for providing a control basis for construction. The diameter of the bottom plate of the settling plate is 60cm, the length of the measuring rod is 5m, generally 100m is buried, and 50m is arranged at the closure section.

S5 filling operation

In general, after the geotextile is laid, the geotextile is manually covered with soil, and then the closed air soil filling construction can be started.

The mud is taken according to the principle of 'far taking and near using and near taking and far transporting', mud cannot be repeatedly taken at a certain place, a deep pit or a deep groove is avoided being formed, and the difficulty in displacement of the diker and the loss of the mud are avoided. The mud discharging is preferably carried out sequentially from far to near to form a natural slope ratio and reduce the loss of the sea mud. The principle of 'line production' and 'thin layer wheel addition' must be implemented, and the filling thickness of each layer should be controlled within 0.5 m. The earth is difficult to compact after being filled into the dike, and natural consolidation is required. When the upper layer is filled, the lower layer has enough natural consolidation time, and soil is prohibited to be continuously added in the vertical direction at the same part to prevent collapse and sliding. In the process of filling earthwork, in order to facilitate the rapid consolidation of the closed air soil, for the closed air soil with exposed high tide level, the drainage work of the filling surface must be done, and each filling layer is approximately flat, and if necessary, a drainage ditch is arranged to drain accumulated water. In order to meet the requirements of later-stage settlement and seepage prevention of the dike body, the height of the dike body is reserved to be 30cm when earthwork construction is carried out, and after the soil body is settled stably and compactly, manual slope adjustment is assisted, so that the design section requirements are met.

S6, shifting of diker

And after a layer of daub is filled, lifting the sea anchor at the bottom of the buoyancy tank by using an anchor winch, starting the anchor winch corresponding to the guide cable to drag the truss to the next location, throwing the sea anchor at the bottom of the buoyancy tank for positioning, and starting a new round of operation.

S7, measuring the sedimentation amount

And (3) measuring the settlement amount after the diker leaves the local area, observing the settlement plate embedded according to the design requirement every three days during construction, and observing the settlement amount once every day if the settlement amount exceeds a normal value. And drawing a curve of the sedimentation amount, the load and the time, and a graph of the sedimentation rate along with the time and the load. And meanwhile, embedding a lateral displacement observation point to observe the horizontal displacement condition. The settling amount should be less than the maximum settling amount allowed by the design, otherwise measures must be taken. According to the construction practice of similar engineering, before the earth is unstable, the settlement speed and the horizontal displacement of the earth obviously exceed the control indexes, and the stable condition is grasped in time through observation so as to take measures in time, if abnormal conditions occur, the measures are taken immediately. The following measures are generally used: the layered loading thickness is reduced, and the number of loading layers is increased; stopping loading and prolonging the intermittent time; in special cases, unloading measures are taken, or a pressing layer is filled outside.

After the above steps are completed, the diker enters the next zone until the first layer in the work area is filled, the second layer construction can be carried out, because the tidal marsh mud needs certain consolidation time to increase the strength, and if the tidal marsh mud is not consolidated to certain strength, the tidal mud is added, so that the soil is lost, and the tidal marsh is useless.
