Description
Technical Field
The utility model relates to a river, lake and river coast dike project, in particular to a tidal bore preventing pile driver for pile driving construction of the river, lake and river coast dike project.
Background
In the current river, lake and sea bank engineering, a concrete pile body and other members are used for constructing a bank protection wall, the bank protection wall is required to be piled on the river, lake and sea, a special engineering ship is adopted for constructing the river bank protection, for example, a Chinese patent for river, navigation channel and bank construction special engineering ship with the patent number of ZL201420439985.3 (with the bulletin number of CN 204078022U) discloses a construction device, which comprises a ship body, a bracket and piling devices arranged on the ship body, and the engineering ship has the defects that the requirements on roads on two banks of the river are low, cofferdams are not required to be arranged during construction, the ship cannot shake due to the fact that the ship is in water, the bracket along with the ship is easy to shake, positioning is difficult, the pile body is difficult to position and splice, and the construction speed is slow and the piling precision is low. At present, a guide mechanism capable of accurately positioning so as to facilitate pile splicing and improve engineering quality is not available in engineering practice.
The construction of river bank protection is carried out by adopting a walking pile driver, as disclosed in China patent No. ZL 20110269494. X (bulletin No. CN 102425165B), which discloses a pile driver, comprising a pile driver body, wherein the pile driver body comprises a first winch, a second winch, a mast, a landing leg oil cylinder, a power system, a hydraulic system and an electric system, the mast is provided with a cylinder type diesel hammer, the cylinder type diesel hammer is connected with the first winch through a steel wire rope, and the pile driver is characterized by also comprising a rotary platform and a walking platform, an auxiliary crane is arranged on the rotary platform, a longitudinal moving mechanism is arranged below the rotary platform, the longitudinal moving mechanism is connected with the rotary platform through a central rotary supporting mechanism, and one side of the longitudinal moving mechanism is provided with an auxiliary supporting ship; the two ends of the rotary platform are respectively provided with a traversing mechanism, and the traversing mechanisms are connected with the supporting leg oil cylinders; a supporting rod and an amplitude-variable oil cylinder are arranged between the mast and the rotary platform; the walking platform is formed by movably connecting a plurality of steel plates.
The river bank pile driver has the following defects:
1. the travelling mechanism adopts a chain or linear bearing structure, the travelling structure is arranged in a river channel, and sediment or small stones in the river channel are easy to block the chain or the linear bearing, so that the travelling mechanism is invalid.
2. The travelling mechanism is only suitable for travelling in a conventional river, such as a large river (e.g. Qian Tangjiang river), because the large river has a tidal bore phenomenon, a large amount of sediment is brought during tidal bore, a large vessel below the supporting leg oil cylinder can be covered, the sediment can be covered on the large vessel for two meters and three meters, and the blocking force caused by the upward movement of the large vessel becomes very large due to the large vessel area, so that the supporting leg oil cylinder can not pull the large vessel out of the sediment any more, and the travelling mechanism walks in the sediment.
3. In the pile hanging process of the walking pile driver, the hung concrete pile is easy to shake and unstable due to the rotation of the rotary platform, so that the walking pile driver has high skill requirements on operators, and is not beneficial to hanging the concrete pile in place, and the pile hanging time is long.
4. When the walking pile driver works, a plurality of concrete piles to be piled need to be piled on the original bank in advance, in order to ensure that the pile driver body can hoist the concrete piles, the concrete piles need to be piled at the edge position closest to the original bank, the weight of a single concrete pile is heavy, if a plurality of concrete piles are piled at the edge position close to the original bank at the same time, a new bank is not constructed, the old bank is likely to be damaged, and in many cases, the bank cost for repairing damage is often larger than that for building a new bank, so that the new bank is not damaged. If the old bank is damaged, the old bank can not be repaired; when a river course with a stepped dyke is constructed, the lower dyke is possibly submerged by water, and the strength of the lower dyke is insufficient, so that the concrete piles and the traveling engineering vehicles are not suitable for being piled up on the lower dyke, that is, the concrete piles are only suitable for being piled up on the upper dyke, but the walking pile drivers in the river course are far away from the upper dyke, and the pile drivers cannot lift the concrete piles placed on the upper dyke, so that the existing walking pile drivers are not suitable for being constructed in the river course of the specific upper dyke and the lower dyke.
In view of the above, the existing walking pile driver can be further improved.
