Problems solved by technology

[0003] The intertidal zone is at the junction of the land and the ocean, and the geological, climate and hydrological conditions are relatively special. During the construction of the motor platform, ships encountered in the construction process cannot reach the predetermined area, and environmental protection requirements make it impossible to repair roads and many other problems. There is no success at home and abroad. Experience can be used for reference

Embodiment Construction

[0029] like Figure 1-6 As shown, the present invention proposes a construction method for an intertidal fan platform, and the construction method includes the following steps:

[0030] (1) Build the paving pad: when the tide is low, set the paving pad around the area to be constructed in the intertidal zone, and drive the engineering vehicle to the paving pad;

[0031] (2) Adjust the posture of the engineering vehicle: it is convenient for the next step of construction;

[0032] (3) hoisting of the foundation column: hoist the foundation column to a place 5-7m away from the ground, and then move it to the top of the intertidal zone to be constructed;

[0033] (4) Subsidence of the foundation column: inserting the foundation column into the shallow layer of the intertidal zone to be constructed;

[0034] (5) Verticality check: check whether the foundation column is perpendicular to the ground, if the vertical condition is not satisfied, repeat steps (3) to step (4) for the f...

Abstract

The invention provides an intertidal zone draught fan platform construction method. The method comprises the following steps of road paving base plate setting up, engineering van gesture adjusting, foundation stand column hoisting, foundation stand column sinking, perpendicularity testing, foundation stand column hammering, guiding frame angle error compensation, pile driver hammerhead rising, foundation stand column array arranging, steel sheet pile cofferdam, foundation excavation, steel bar binding and concrete pouring. The intertidal zone draught fan platform construction method has the following beneficial effects that under the condition that the difference of the elevation of the natural mud surface and the top elevation of the draught fan foundation plane is large, the method has the characteristics of being convenient in draught fan tower cylinder subsequent setting up, low in construction economic cost, high in reliable connectivity and the like, and high popularization value is achieved in an intertidal zone.

Description

technical field [0001] The invention relates to a construction method for a wind turbine foundation, in particular to a construction method for a wind turbine platform in an intertidal zone. Background technique [0002] my country has a long coastline, and the eastern coast has a vast sea area with a water depth of 2-15m. According to the same method as the onshore wind energy resources, the exploitable offshore wind energy resources are about 750 million kW, which is three times that of the onshore wind energy resources. It has large-scale development. Resource potential of wind farms. The intertidal zone is a sea area that is submerged by high tide and exposed by ebb tide. The development cost of wind power development in the intertidal zone is much lower than that of the offshore area completely submerged by seawater. Therefore, from the perspective of development potential and investment cost, the intertidal zone is currently the key area for wind power development. ...
