Background technology
Intertidal zone is between the high and low tidal level of spring tide, the area being submerged with tiding and exposing.According to preresearch estimates, intertidal zone annual mean wind speed can reach 67 meter per seconds, therefore possesses utilizable wind energy in intertidal zone.For intertidal belt wind electric engineering, it is mainly concerned with the construction of blower foundation and how installs blower fan.
For blower foundation construction technology, there are two kinds of techniques at present.One is single pile blower foundation construction technology, and another kind is pile type foundation construction technology.For single pile blower foundation construction technology, intertidal zone fan basis single pile construction technology has following different compared with conventional construction technique: adopt the steel pipe pile of diameter greatly between 4.5-5.5 rice as blower foundation in intertidal zone; And conventional blower basis all adopts 1.2-2 rice diameter steel pipe pile.The way of the supporting diesel hammer of the pile driving barge adopted in conventional blower foundation construction or hydraulic hammer, shipping draft is comparatively dark, and in intertidal zone, construction efficiency is low.
Therefore, need to provide a kind of construction process for single-pile wind turbine foundation in intertidal zone to solve the problem.
Summary of the invention
In order to solve this problem, the invention discloses a kind of construction process for single-pile wind turbine foundation in intertidal zone, described construction technology comprises the following steps:
(1) station keeping ship, cargo ship and crane ship are dragged to appointed place by high water time;
(2) crane ship to be cast anchor location;
(3) foundation pile level is lifted;
(4) by foundation pile staking out;
(5) foundation columns is sent into pile gripper;
(6) foundation pile verticality is adjusted;
(7) foundation pile is drowned oneself;
(8) verticality inspection, if do not met, re-starts foundation pile and drowns oneself;
(9) suspension centre is removed;
(10) pile hammer, hammer are sling;
(11) hydraulic impact hammer dynamical system is started;
(12) jump bit is beaten;
(13) verticality inspection, if verticality does not meet, then adjusts jump bit and beats;
(14) pile sinking is impacted;
(15) absolute altitude, degree of pouring into are measured, if absolute altitude, degree of pouring into do not meet, then the step of pile sinking is impacted in adjustment;
(16) hammer is stopped;
(17) crane ship unloads.
Preferably, above-mentioned steps (4) is further comprising the steps:
Wire rope is connected on pile body;
Gib head is slowly raised, receives luffing simultaneously, rotate crane barge, control pile body and reverse;
When close on sling time, rotate crane barge to set-up positions;
Pile body is sling.
The present invention has following beneficial effect: solve region, intertidal zone blower foundation construction effective operation time short, the problem that construction efficiency is low, greatly reduces construction cost.
In summary of the invention part, introduce the concept of a series of reduced form, this will further describe in detailed description of the invention part.Content part of the present invention does not also mean that the key feature and essential features that will attempt to limit technical scheme required for protection, does not more mean that the protection domain attempting to determine technical scheme required for protection.
