Four parts manhole enabling an easy install and height adjustment

A manhole comprised of four parts is provided. The manhole is comprised of an outer-manhole pipe, an inner-manhole pipe, a manhole cover, and a support pipe. Pluralities of concave arc band shape blades are horizontally developed along the inner surface of the outer manhole pipe. Same number of convex arc band shape blades is horizontally developed along the outer surface of the inner manhole pipe. The inner-manhole pipe is inserted into the outer-manhole pipe vertically when the two kinds of arc shape blades aligned to make pass way for each other. When a desired height is reached, workers rotate the inner-manhole pipe 60 degrees horizontally and put down the inner-manhole pipe. Then the two kinds of blades are overlapped and fix the height of the manhole cover. A support pipe, comprised of two pieces of equal hemi-pipe connected one end, is engaged between the top flange of the inner-manhole pipe and top end of the outer manhole pipe to hold and support the distance between them.

Offshore wind turbine and method for making same

The present invention relates to wind generators installed off-shore, in particular at sea, to support structures forming a part of such wind generators, and to methods of making and installing such wind generators. The technical field of the invention is that of making, transporting, and installing wind generators for producing electricity, more particularly off-shore, and in large numbers, so as to form wind "farms". The wind generator of the invention comprises a wind turbine and a deployable telescopic pylon or support supporting the turbine, and a gravity base supporting the pylon or support.

Ice composite bodies

PCT No. PCT / IE97 / 00002 Sec. 371 Date Jul. 10, 1998 Sec. 102(e) Date Jul. 10, 1998 PCT Filed Jan. 10, 1997 PCT Pub. No. WO97 / 25483 PCT Pub. Date Jul. 17, 1997An ice composite body has an inner ice core covered by a protective outer armor layer. Thermal insulation is provided between the inner core and the outer armor layer. Refrigeration is accomplished by a system of conduits for refrigerant are located within the body. The insulation and the refrigeration are adapted to maintain the ice core in a frozen condition relative to the ambient temperature. The base of the body cavity can be in direct contact with the water bed such that the ice core is freeze bonded to an advancing ice front in the water bed. The ice composite body provides structures of equal or greater strength than equivalent structures using conventional materials.

Phase Estimation From Rotating Sensors To Get a Toolface

Measurements made by a rotating sensor on a bottomhole assembly are used to determine the toolface angle of the BHA. The method includes using a phase locked loop (PLL) to determine a phase difference between the sensor output and a reference signal.

Apparatus, systems and methods for erecting an offshore wind turbine assembly

An embodiment of an apparatus useful for up-righting a wind turbine pillar at an offshore installation location includes a barge having first and second towers and an open area therebetween and which extends downwardly to the offshore installation location. At least two pulling lines extend from the towers to the pillar and are useful to assist in moving the pillar into a generally up-right orientation between the towers and lowering the pillar downwardly through the open area to the offshore installation location.

Modular building materials

Building materials of modules of at least one mortise and tenon and either a curvilinear side face or joinder of the modules at angles other than zero and ninety degrees. Lateral ends of the modules are flush with lateral ends of adjacent modules. Preferably, the modules are: (1) of a low density aggregate cementitious mix; and / or (2) have a hollow space extending from the mortise to the tenon and include a structural support member passing through the hollow space and a compression retainer securing the structural support member to the modules; and / or (3) have grooves circumscribing the modules and which are proximate corresponding grooves on modules placed on top or below. The modules are preferably sealed to one another with sealant placed in the grooves.

Mechanical interlocking means for retaining wall

An improved method and system for attaching a welded wire grid-work panel to a plurality of face panels of a retaining wall. The method first begins by providing a plurality of stackable face panels, each face panel having a plurality of anchor links fixed within a back portion of the face panels. Each of the anchor links forms a vertical loop extending outwardly generally perpendicular to the back portion of the face panels. Additionally, each anchor link includes two legs extending laterally from each anchor link within the face panel. Next, a first tier of the face panels is disposed at the bottom of the embankment being erected. Soil is then back-filled behind the first tier of panels to a level of the anchor links disposed within the first tier of face panels. A welded wire grid-work panel, which extends perpendicularly from the back portion of the face panels into a soil embankment, is positioned so that a plurality of wire loops at the edge of the grid-work panel aligns with the vertical loops. A connector rod is extended through the vertical loops of the anchor links and the wire loops of the grid-work panel. Next, additional soil is back-filled behind the first tier of face panels and over the anchor links, vertical loops, wire loops, and grid-work panel to a level at a top edge of the first tier of face panels. The method is repeated until the desired height of the embankment is attained.

Retaining wall block

InactiveUS7168892B1Reduced and zero predetermined setbackArtificial islandsCoastlines protectionVertical planeEngineering
A retaining wall block (1) has parallel top and bottom faces (2, 3), a front face (4), a rear face (5), first and second side wall faces (6, 7) and a vertical plane of symmetry (S) extending between the front and rear faces (4, 5). The block (1) is formed as a body portion (8) including the front face (4), a head portion (9) including the rear face (5) and a neck portion (10) connecting the body portion (8) and the head portion (9). The body, head and neck portions (8, 9, 10) each extend between the top and bottom faces (2, 3) and between the first and second side wall faces (6, 7). An opening (13)′ extends through the neck portion (10) from the top face (2) to the bottom face (3), dividing the neck portion (10) into first and second neck wall members (14, 15) extending rearwardly from the body portion (8) to the head portion (9). First and second pin holes (16 and 17) are each disposed in the body portion (8) and open onto the top face (2) for receiving a pin (50, 51) with a free end of the pin protruding beyond the top face. First and second pin receiving cavities (18, 19) are each disposed in the body portion (8) and open onto the bottom face (3) for receiving the free end of a pin (50, 51) received in a pin hole (16 and 17) of an adjacent block (1) disposed therebeneath so as to interlock the blocks (1) with a predetermined setback. The neck wall members (14, 15), pin holes (16 and 17) and pin receiving cavities (18, 19) are positioned such that a first plane (P1) extending parallel to the plane of symmetry (5) passes through the first pin receiving cavity (18), first pin hole (16) and first neck wall member (14) and a second plane (P2) extending parallel to the plane of symmetry (5) passes through the second pin receiving cavity (19), second pin hole (17) and second neck wall member (15).

Multi-channel retaining wall block and system

A retaining wall block system having multiple sizes and shapes of blocks with differently dimensioned, interchangeable front and back faces. The blocks are used to construct an irregularly textured wall having a weathered, natural appearance. Multiple channels in the lower face of the block are used to engage pins in pin-receiving apertures to form an attachment system. Horizontal reinforcing members are also used in the channels and vertical reinforcing members are used in cores of adjacent blocks for reinforcing a wall. Reinforcing geosynthetic materials can also be firmly held in a wall by means of the pins or by connectors adapted to fit in the block channels.
