Plant Equipment - AP3036, Part 11 (1st Ed) & Part 12 (2nd Ed) - Well-boring Equipment/Part 12 (2nd Ed) - Soil Stabilisation Equipment


It would appear that the release of the 1st Edition of AP3036 took place in late 1943/early 1944 as new pages begin to appear from February 194  The original edition was probably replaced by the 2nd edition in late 1950/early 1951 as the first Amendment List (AL1) was issued in March 195  AP3036 (2nd Edition) was also probably the final edition as it numerous ALs were issued until AL99 in November 1960.

The list below shows all the plant equipment shown in both editions of AP3036 between 1944 and 1960 with much of the later equipment still being in use until the RAF Airfield Construction Branch disbanded on 1 April 196  More details on each item of equipment will be added over time.  The listings in these documents were divided into a number of Parts covering a general category of equipment and each Part was further split into Sections, each covering a specific type of equipment

(1st Ed) indicates that the Part/Section was in the original 1st Edition of AP3036.  (2nd Ed) indicates that the Part/Section was in the original 2nd Edition of AP3036, whilst the addition of AL? indicates which Amendment List, introduced this Part/Section following the original release of AP3036 (2nd Edition)

Godwin deep well pump, Type B (Lister 5/1 diesel engine)

Godwin deep well pump, Type B (Lister 5/1 diesel engine)

Description
  1. This type of pump is for use where the well is deep and it is necessary that the pump bucket and cylinder should be located at the bottom of the borehole.

  2. The bucket is operated by pump rods, which pass through the rising main, and are attached to a crosshead which works on guides secured to the pump body.  The required reciprocal motion is obtained by two connecting rods - one on each side - attached at their upper ends to the crosshead and at their lower ends to crank pins.  The crank pins are mounted on spur wheels which mesh with pinions keyed to a driving shaft provided with a fast and loose pulley.  The pulleys are coupled by means of a belt to a Lister 5/1 diesel engine.

  3. A balancing mechanism is attached to the crosshead to balance the weight of the pump rods and bucket.  This consists of a chain which after passing upwards over a sprocket and roller, falls downwards and is connected to a rod for the attachment of the balance weights.

MT required for transportation -

  • AEC, Matador, 4x4, Tractor

This item of equipment appears to have been added to the 2nd Edition by the issue of AL15.

Engine

Width of driving belt - 4 in.

The below ground equipment will vary according to the depth of the well and the particular requirements of each installation.       The following is an example only of the below ground parts required in a typical installation used to raise water from a 262 foot deep well to a head of 30 feet above the surface.      

Rising main - 250 feet of 4 in. dia. rising main pipe

Pump rods - 250 feet of tubular pump rods fitted with all necessary couplings, locknuts and guides

Edeco deep well pump Mk 3 (Petter AV2 diesel engine)

Edeco deep well pump Mk 3 (Petter AV2 diesel engine)

Description
  1. The Edeco Mk. 3 Deepwell Pump is used for raising water where owing to the depth of the well, it is necessary that the pump cylinder and bucket should be located below the water level.

  2. The bucket is operated by pump rods which are connected to a polished rod working through a stuffing box, the upper end of the polished rod being attached by a clamp to the carrier bar, which, in turn, is slung from the walking beam mulehead by a wire rope sling.

  3. The walking beam is provided with detachable balance weights which can be applied or removed in order to balance out the total weight of pump rods in suspension and half the weight of the water column.  The actual weights used will depend upon the depth of the well and the diameter of the pump cylinder.

  4. The power for operating the plant is supplied by a Petter AV2 diesel engine

  5. A hoist, which is supplied separately and which may be used to service a number of pumping units is arranged to bolt on to the pump unit frame after disconnecting the pitman which is then swung down to the ground.  It is coupled by a friction clutch to the crank disc and is engaged by a hand-operated lever when hoisting.  Lowering is controlled by a foot-operated hand brake.

Description
  1. The Seaman Rotary Pulvi-mixer Model MHD-72 is a speed rotary pulverizer and mixer.  Its purpose is to pulverise or mix materials on site.  Power is supplied by a Waukesha gasoline engine Type MZRU mounted on the forward part of the machine.  The power is transmitted from the engine to the rotor assembly by shafts, a double universal joint and a spiral bevel gear.

  2. The mixer is primarily designed for mixing any type of binder with all kinds of soils or aggregates.

  3. The mixer is fitted with two pneumatic tyred wheels and a towing eye so that it can be towed by a tractor.
