Hydroseeding Mix and Method Of Application

HYDROSEEDING MIX & METHOD OF APPLICATION

(CAPACITY OF HYDROSEEDER 1, 000 liters)

HYDROSEEDING MIX

1. Pump water into hydroseeder to level. 2. Free gear and start engine. 3. Put in mulch (if paper mulch is used 15 to 20 kg dry weight is recommended) 4. Next add in 30 kg Soil Tackifier (R1187) 5. Put in 8 to 10 kg grass seeds. You may add millet if you wish for fast establishment of

greens/ vegitation.

6. Add one bag (40-50 kg) of Bio-Super 1 fertilizer with the mixture. 7. Finally top up with water.

METHOD OF APPLICATION

Before engaging the gear, the person who will do the spraying must hold tight the

nozzle and have firm footing on stable ground as he will expect a strong back-kick the

moment the slurry shoots out of the nozzle.

Do not shoot the slurry directly to the soil surface. Instead, it should be done in the

form of raindrops in a uniform pattern. Ensure even coverage of slurry on soil surface.

One machine load with proper application can cover approximately 600 to 700 m2.

Watering (also in the form of raindrops) on the hydroseeded area can start

immediately the next day and must be continued daily in the initial stage to ensure

speedy germination and growth. Light watering will not help much due to our hot

climatic condition. Therefore, sufficient and proper watering must be done ensuring

water seep into the soil yet avoiding overflow of water on the soil surface.

NOTE: Hydroseeding shall never be applied during, before or immediately following

rainfall. Avoid application in high winds. Machines and tools should be flushed and clean

with water immediately after use. All moving parts should be oiled and greased regularly.

Method Statement For Dynamic Load Test And Pile Driving Analysis Test

METHOD STATEMENT FOR DYNAMIC LOAD TEST AND PILE

DRIVING ANALYSIS TEST

DYNAMIC PILE TESTING EQUIPMENT Dynamic pile testing and instrumentation will be performed using the PDA/CAPWAP system on the

tested pile.

Measurements of the force and velocity waves induced in the pile during pile testing are collected by

force and acceleration transducers, which are fixed near the pile head.

TEST PROCEDURE Dynamic pile testing can be conducted on bored piles by means of a heavy impact at the pile head.

The impact is often provided by a suitable drop weight and the response is measured in terms of

force and acceleration close to the pile head.

For testing, the pile may require some excavation prior to the field-testing. The exposed length of

pile have to be at least 1.5 diameters of the pile or 1.0m whichever is greater above the penetration

level for pile instrumentation.

The pile head will be protected for the impact by means of steel casing, which is used to build up the

pile.

A guide frame will be positioned onto the pile. The frame is used to guide the drop weight under the

fall.

A steel plate of about 50mm is placed on top of the pile head so as to protect the pile head from

damage under the hammer fall.

3 nos. of 6mm diameter holes are drilled on two opposite sides of the pile for attachment of gauges

at 1.5 diameters below the pile top. Two pairs of force transducer and accelerometer are bolted

onto the pile using wall plugs.

During testing, the transducers will be connected to the Pile Driving Analyzer and its associated

storage computer equipment via a main 19-wire cable (up to 50m long).

The client will supply and operate the piling hammer to induce a driving force onto the pile. The drop

weight is positioned and drop onto the pile under controlled height. Dynamic measurement of force

and velocity will be collected by gauges attached to the pile. This data will be processed by the PDA

to give immediate visual and permanent record onsite.

Each blow monitored by the PDA will be displayed on the built-in LCD screen/ oscilloscope in the

form of force and velocity traces for immediate data quality control and computation. The PDA will

also provide onsite results such as: -

a. Mobilized static load capacity based on the CASE method

b. Pile Integrity location and extent of damage

c. Pile Stresses maximum compression forces at pile top/ toe

d. Hammer Performance maximum energy transferred to the pile

The transducers and accelerometers will be dismantled at the end of the testing. PDA data will be

transferred and stored in a disk for subsequent report and analysis.

The above procedure will be repeated for the next pile test.

A survey of the pile top is taken before and after the testing to obtain the permanent set per blow.

The client is also to provide the bore log information and pile construction record for the test pile.

DATA ASSESSMENT AND CAPWAP ANALYSIS The pile top force and velocity signals recorded in the field will be processed and a representative

blow will be selected for further analysis using the CAPWAP suite of computer software.

CAPWAP analysis involves applying the measured pile top force/ velocity time record as a boundary

condition to a wave equation model of the pile comprising of continuous segments.

The soil model is continuously adjusted in an iterative procedure until the computed pile top force

time record is in close agreement to the measured pile top force time record. When good agreement

is obtained between measured and computed pile top data, the soil resistance parameters are

assumed to provide the best accurate model of the actual soil behavior.

A typical presentation of the CAPWAP results will be as follows: -

1. CAPWAP model a match curve of computed pile top force to the measured pile top force time record

2. Total computed soil capacity sum of Skin Friction and Toe Bearing 3. Computing Load against Settlement curve

REPORTING Initial results are normally available within 24 hours or two working days of the completion of each

test. These shall include the following: -

a) the assumed damping factor

b) the assumed wavespeed

c) the maximum force applied to the pile head

d) the maximum pile head velocity

e) the maximum energy imparted to the pile

f) the maximum tension force experience by the pile

g) the field estimated static resistance

h) the maximum driving stresses

A full report shall be submitted within 10 days of the completion of the testing. This report shall

include the follwing: -

a) report all information given in preliminary report

b) information of pile size and working load

c) date of pile installation

d) date of test

e) pile identification and location

f) length of pile below existing surface

g) total pile length, including projection above existing surface at time of testing

h) length of pile from instrumentation position to pile toe

i) hammer type

j) best estimated static capacity

k) pile integrity

l) force/ velocity versus time trace

m) computed load versus settlement

QUALITY ASSURANCE Quality control is the single most important element in a successful dynamic test. Every stage in

setting up and operation of the testing is subject to thorough quality assurance checking procedures.

The equipment has many inbuilt checking routines and signals warning display.

Quality assurance procedures are also followed in data processing and CAPWAP analysis. Check

reviews and re-analysis will be carried out prior to final reporting.

The international acceptance of PDA/CAPWAP system and the proposal to use Geotechnical

engineers trained and experienced in the application of the system are the key issues in providing

the necessary quality assurance.

Method Statement For Pile Load Test By Kentledge Method

METHOD STATEMENT FOR PILE LOAD TEST BY KENTLEDGE METHOD 1.0 INTRODUCTION

Vertical Compression pile load test is usually carried out to ensure the structural and Geotechnical

soundness of pile and also to predict settlement of other piles. The common procedure is to increase

the load in stages until the proposed working load is reached and then to unload and reduce the

load in stage and to leave the load off until the rise or rebound substantially leases.

A variety of test procedures and method have been developed for carrying pile load, amongst the

most common procedure for pile load test is by using Kentledge method where a static load is apply
