Water area screw anchor construction equipment

Abstract

The invention discloses water area screw anchor construction equipment which comprises a screw anchor part, a floating platform, an anchor lowering machine body and a hydraulic power station. The screw anchor part is composed of a screw anchor rod with an anchor tray, multiple connecting rods and a gravity block, directly contacts with a soil body and interacts with the same, and anti-drawing requirements of the anchor rod are met; the floating platform is composed of a floating body formed by splicing engineering plastic buoys, a bearing steel frame formed by splicing multiple steel structure modules, a supporting frame and an inserting rod and used for fixing the anchor lowering machine body and providing buoyancy needed by the whole. A modularization design concept is utilized, and the floating platform which is splicable is adopted to replace a ship or a special pontoon, so that convenience is brought to transition construction and site mounting; measures like using a high-strength steel material, reasonably arranging size and position of the screw anchor tray and adopting a combined anchoring mode combined with the gravity anchor are adopted, so that anti-drawing performance of a screw anchor is improved and the water area screw anchor construction equipment is enabled to meet anchor lowering construction needs in an overwater operating environment.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of electric power line construction, in particular to construction equipment for anchoring construction with spiral anchors in water environment. [0003] 【Background technique】 [0004] In the process of power transmission and transformation construction of the power grid, the newly-built transmission line will inevitably pass through the river network area with many paddy fields and lakes. In order to meet the needs of anchorage and anchorage during engineering operations such as pole tower erection and wire erection, limited by the terrain characteristics of the river network, Ground anchors need to be set underwater. [0005] The current ground anchor anchoring methods used in the construction of power transmission and transformation projects include pile anchors, gravity anchors and spiral anchors. However, these ground anchor anchors have some deficiencies in water engineering construction. Fo...

Problems solved by technology

[0005] The current ground anchor anchoring methods used in the construction of power transmission and transformation projects include pile anchors, gravity anchors and spiral anchors. However, these ground anchor anchors have some deficiencies in water engineering construction. For example, the pile-type ground anchor needs to excavate the earthwork, the engineering volume is large, and it cannot be used due to the terrain restrictions of the water area; although the gravity ground anchor has a wide range of applications, it is difficult to provide a large anchoring force due to the large gravity load required; the spiral ground anchor The anchor is easy to use and can provide a large anchoring force, but the current anchoring equipment is only designed for land construction, which is bulky, inconvenient to transport and install, and difficult to meet the requirements of water construction
