Abstract
The invention discloses a method for planting piles in a seabed bare rock or shallow overburden area through balancing weights. The method includes the following steps that first, foundation riprapping is performed; second, the balancing weights are hoisted; third, a gondola is lifted and carried; fourth, the balancing weights are installed. The method for planting piles in the seabed bare rock or shallow overburden area through the balancing weights solves the problem that it is difficult to plant piles in the seabed bare rock or shallow overburden area, avoids the influence factors of poor geological conditions making the piles difficult to plant and guarantees construction efficiency. A construction machine used in the installing process is simple and easy to operate.
Description
Technical field
The present invention relates to the naked rock in a kind of seabed or shallow overburden region balancing weight is planted piling method.
Background technology
In prior art, in trestle construction steel pipe pile plant stake all take vibrating hammer pile-sinking method as main, but naked rock or shallow overburden region cannot be implemented in seabed.
Summary of the invention
The object of this invention is to provide a kind of naked rock in the seabed of planting a problem or shallow overburden region balancing weight that has solved in seabed naked rock or shallow overburden region and plant piling method.
The technical scheme that the present invention adopted is for achieving the above object: the naked rock in a kind of seabed or shallow overburden region balancing weight are planted piling method, comprise the following steps:
A, basic jackstone: refuted and added backacter and carry out jackstone operation by haul side, after the lower guide rail of diving, commander's backacter carries out jackstone in formulation position, and Divers Yong Gua road strikes off;
B, balancing weight lifting: crane ship is ready, crane ship puts down main hook, by snap ring, wire rope and balancing weight block are connected, hang on the main hook of crane ship with wire rope again, after wire rope all hangs up properly, check the suspension situation of wire rope and eave tile and snap ring, confirm errorless after, commander's crane ship plays hook, then makes to hang ship and rises and hook and stranded cable, move ship balancing weight block is moved to and hung on ship;
Ship is hung in C, delivery: tugboat haul is hung ship and stayed position to installation region, hang on ship survey crew by GPS locate hang ship to corresponding balancing weight infield in;
D, balancing weight are installed: while hanging the installation of ship lifting balancing weight, ship's staff regulates balancing weight direction, and diver contacts by setting-out baseline and liaison man, and the full-time commanding of commander's loop wheel machine, regulates balancing weight to be in place.
The height minimum of the basic jackstone in described steps A is 0.5m.
In balancing weight in described step B, be prefabricated with steel pipe pile, and in steel pipe pile fluid concrete.
In described step B, every wire rope is connected in a certain order with each suspension centre.
While hanging the installation of ship lifting balancing weight in described step D, first on two steel pipe piles, install respectively two cable wind ropes, ship's staff regulates balancing weight direction by cable wind rope.
In described step D, in balancing weight installation process He after installation, to carry out underwater photography, carry out underwater camera and take pictures completing the counterweight block bottom of installation and the rubble leveling basis at edge, retain image data.
After in described step D, balancing weight is in place, survey crew uses coordinate to carry out repetition measurement by GPS to two steel pipe piles, and use guiding ruler to measure steel pipe pile verticality, after meeting the demands, diver unloads snap ring, is reinstalled on wire rope, by suspension hook, suspender is carried back, hang ship and adjust position, carry out next fast balancing weight and install.
A kind of naked rock in seabed of the present invention or shallow overburden region balancing weight are planted piling method, have solved the naked rock in seabed or shallow overburden region and have planted a difficult problem; Avoid planting because of features as poor geologic condition the influence factor of stake difficulty, guaranteed efficiency of construction; In installation process, construction equipment used is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is the pierre-perdue floor map that the naked rock in a kind of seabed of the present invention or shallow overburden region balancing weight are planted piling method.
Fig. 2 is that a kind of naked rock in seabed of the present invention or shallow overburden region balancing weight are planted piling method pierre-perdue schematic cross-section.
Fig. 3 is that a kind of naked rock in seabed of the present invention or shallow overburden region balancing weight are planted piling method balancing weight floor map.
Fig. 4 is that a kind of naked rock in seabed of the present invention or shallow overburden region balancing weight are planted piling method balancing weight schematic cross-section.
The specific embodiment
As shown in Figures 1 to 4, the naked rock in seabed or shallow overburden region balancing weight are planted piling method, the height minimum thickness of pierre-perdue is 0.5m, leg wire of slope is not less than 1.0m apart from balancing weight edge, steel pipe pile 1 is in advance in balancing weight, and at the interior fluid concrete of steel pipe pile 1, its concrete installation steps are: A, basic jackstone: the construction technology that base bed flattening adopts guide rail to scrape, refute and add backacter and carry out jackstone operation 300T haul side, diving has descended after guide rail, commander's backacter carries out jackstone in formulation position, and Divers Yong Gua road strikes off, B, balancing weight lifting: after crane ship is ready, crane ship slowly puts down main hook, lifting librarian use snap ring connects wire rope and block, again two wire rope are hung on the eave tile of crane ship, the connection of every wire rope and each suspension centre is according to a definite sequence, after wire rope all hangs up properly, lifting personnel carefully check suspension situation and eave tile and the snap ring of wire rope, avoid the situation that occurs that wire rope laminates mutually, confirm errorless after, commander's crane ship slowly plays hook, after wire rope is energetic, stop hooking, again check every wire rope, the situation of snap ring, then continue commander's crane ship and slowly play hook, when block hangs ground 10cm, crane ship has stopped hooking again, again conscientiously checked the situation of block and Current Collector Sleave by lifting personnel, check whether wire rope has fracture of wire, necking down, wearing and tearing, corrosion, the situations such as distortion, in work progress, to note strengthening the maintaining to wire rope, after guaranteeing that the service behaviour of wire rope is normal, notice is hung ship and is played hook stranded cable, moving ship moves to block stably and hangs on ship, ship is hung in C, delivery: tugboat haul is hung ship and stayed position to installation region, hang on ship survey crew by GPS locate hang ship to corresponding balancing weight infield in, D, balancing weight is installed: while hanging the installation of ship lifting balancing weight, two steel pipe piles 1 on install respectively and pull two cable ropes, ship's staff regulates balancing weight direction by cable rope, diver contacts by setting-out baseline and liaison man, the full-time commanding of commander's loop wheel machine, adjusting balancing weight is in place, survey crew uses GPS to use coordinate to carry out repetition measurement to two steel pipe piles 1 and meets the demands, and after using guiding ruler measurement steel pipe pile verticality to meet the demands, diver unloads snap ring, be reinstalled on wire rope, by suspension hook, suspender is carried back, hang ship and adjust position, carrying out next fast balancing weight installs.The naked rock in seabed of the present invention or shallow overburden region balancing weight are planted piling method, have solved the naked rock in seabed or shallow overburden region and have planted a difficult problem; Avoid planting because of features as poor geologic condition the influence factor of stake difficulty, guaranteed efficiency of construction; In installation process, construction equipment used is simple, easy to operate.
