A. GENERAL

The parallel slide rail system PV is available in single rail (EGPV) and double rail (DGPV) or single and double guide. Respectively to shield excavation depth of 2.0 to 8.0m. These systems are set up using the lowering and cut method or « dig & push », without vibration, using the excavator carrying earthworks. This system allows :

Ensure safety of people working in the excavation,

ensure the stability of the surrounding terrain and nearby homes or buildings (underground structures, roads, buildings)

to limit the influence of the trench,

to have a continuous linear and joined limiting water arrivals All our products conform to the following standards: DIN EN 13331 parts 1 & 2 DIN 4124 Agrement TBG (german normalization)

B. HANDLING AND TRANSPORTATION

All components of the shoring include rings and handling points. The equipment must only be used by those handling points. The chains are preferable to handling wire rope slings. Chains handling must match the weight to be handled and the length of the elements. To prevent the accidental release of the load, it is strongly recommended to use self-closing hooks. Slings must conform, periodically tested and certified The material should be stored flat on the ground, preferably on wooden battens to facilitate re-covery. During handling by the excavator or crane, it is forbidden to keep under load. Be sure to take advantage of an open area for safe handling of loads such as poles, electrical cables, overhead lines, buildings, traffic, etc ...

D. ASSEMBLY INSTRUCTION

For reasons of space and safety of loading, unloading and transport, shoring happens on sites remo-ved. First and foremost, you must be a portico consisting assembly slides carts. Provide an excavator or forklift for assembly, handling slings, wrench, battens, two or three compa-nions. Following the diagram below, rigidly screw as required to the widths (HEB160/EGPV - HEB240/DGPV) the carriage, using the supplied hardware (M16 * 70HV key 24/EGPV - M24 * 85HV key 36 / DGPV or 41/DGPV).

1. Assembly spacers and sliding frame, forming the

trolley shaped rigid parallelogram.

2. Insert the trolley in the slide by sliding on his long

and lock it with the supplied retainers, by introdu-

cing them into the corresponding holes and by tur-

ning a quarter turn minimum.

3. Slide the second rail and block it in the same man-

ner with stopping bolts.




4. This same arrangement should be made for all por-

tals.




E. INSTALLATION INSTRUCTION

The first elements are paramount in the successful completion of the trench. It is then necessary to apply to the establishment of the first portico. Mounted portico are handled by lifting chain slings and hooks on the rails or on trolleys. Reminder: handling strings must match the weight to handle. The ends shall be fitted with auto-matic screed hooks. Observe the opening slings angles.

Reminder: Take the time needed to set up the first elements. This care and attention will save time for the rest of the site during the extraction of material and its rotation, the rate of progress will be all as-sured. Remember to check the connections and tighten if necessary during construction equipment during rotations.

Note: All components of the shoring include rings and anchors. The equipment must only be used by those handling points.




2. Present the first gantry perpendi-cular to the trench and ensure good verticality of the latter,

1. Make a pre-excavation over a length of a section (≈ 4.00m for pa-nels of 3.50m) and a equivalent to that of overall porticos width,

3. Slide header panels in the outer slide rails,

4. Adjustment of the panels in alignment and spacing, and then laying the second gantry. Ensure that the panels are parallel.

Reminder: the first element is important, watch your operator for the portico is perfectly vertical to the longitudinal axis and the lateral axis.




5. ''Cover up'' the end of the plate with a new portico (T-section into C-section).

6.Start earthmoving inside the section. The descent is by cuting method that is to say ss the excava-tion. Panels and rails are down alternately. Feet cant these ele-ments allow the ground to attack.

Depending on the terrain encountered, in order to limit the rise in soil excavation bottom, the panels will precede the earthmoving a few inches (toe of 20 to 30 cm).

Reminder: to know the direction in which the panel is to be introduced, you can rely on its bevel. Bevel direction of the panel is similar to the bevel direction of the slide.

NB: for the double slide, switch panel in the outer rail.




Head protector panels are provided to assist the descent of the panels.

7. The parallelogram « boogie car » slide over the entire height of the slide. 8. During the earthmoving phase, get the lowest possible so that the operator has a clear field of vision.

Reminder: Follow a regular and alternate descent panels and slides. For best performance, follow the vertical slides in both axes.

9. Once the level of the excavation bottom is reached, proceed to lift the parallelogram frame to clear the space necessary to carry out the work. NB: do not forget to first remove the retainers in the slides. The section has reached the desired depth, the preparation of bottom trench can start and excavator can get down to earthmoving and the esta-blishment of panels and following sli-des.

8. a/ For the simple slide, once the top of the panel has reached ground level, set up the top panel onto the base panel and continue earthmoving until the final level.

8. b/ For the double slide rail, when the upper panel reaches the ground level (10 cm as a plinth), establishing the second base panel in the inner rail, continue earthmoving by pushing only inner panels. Panels engaged in the outer rails are maintained by the earth pressure.




F. Extraction

Generally, the excavator has made the establishment, also performs the removal. This removal is done strictly in the reverse pose, namely, gradual rise in alternating panels and rails for compaction neat. The extraction of the panels can be effected in successive stages, according to the height of compacted backfill (limited by the capacity of the compactor and the tensile force required for ex-traction of the panels). Check tightness of bolts porticos before using the shoring.

Tip: extraction chains are recommended, they should made with links of large diameter.




9. Laying items then fill and compaction. Compaction should be phased, the rise of the trench shore and follow the embankment precede compaction to avoid decompression and surrounding disorders.

7. Place the interior panels. Resume earthmoving. These are the panels that continue the descent.

1. Pre-excavation of approximately 1.3 m depending on the soil type. Present the first portal.

4. Excavate within the tool trench shoring. Help lowering slides and panels with the full bucket. In difficult cases use the head protector panels.

8. The system has reached the bot-tom of the excavation, the sliding car-riages can be traced back to free spa-ce for the installation of tubes or rec-tangular shape.

2. Place the upper panels in the outer slide rails.

5. Place top panels on the base pa-nels and resume earthmoving. Conti-nue down the panels and slides si-multaneously.

3. Close length (or span) with a new portico.

6. Continue the excavation. In the case of bad soil, earthworks must not exceed the lower bevel panel.

9. Precise grading and unhurried achieves the bottom of the excava-tion without surprises and guaran-tees removing the tool comfortable.




How to get a shielded pit without any intermediate strut does not interfere making the work?

The solution: the operation is to remove the struts and relea-se the congested area. It is then pushed back efforts suffered by the shield. Substituting the struts by a low carrier and a high belt (and/or intermediate of depth). The bottom support can be formed by a belt HEB or a rein-forced concrete slab (This must be cast against the shielding walls, we must protect them with expanded polystyrene, for example, will prevent laitances to penetrate the interstices of the slides) or posts toe and / or panels according to the case. Up support will be made with a belt HEB positioned outside and act superior waling thus ensuring that the top of the shield. The connection between the waling and the shoring is through the slides. Different mounting options: console by en-gaging in the posts by welding, or by other ways.




Example of support for exterior waling. The system of plates is positioned on the upper part of the slides and can receive up to a section HEB500. Easy to set up, it in no way contradicts the removal of intermediate stays.
