Description
Technical field
The invention belongs to explosion field, more particularly, to the processing of big cross section depth foundation trench soft base, for embankment, breakwater,
The method of the big cross section embankment breakwater depth foundation trench silt soft foundation explosion method processing of the Soft Ground of the engineerings such as shore protection.
Background technology
Strong area is acted in trends such as Nearshore Shallow Sea area, Hekou District, straits and water channel exits, trend is to continental shelf
The a large amount of loose terrestrial sediments in seabed are eroded, carry and are accumulated again, are formed a series of hundreds and thousands of rice of extensions, are up to counted
Ten meters, the alternate ribbon sea-floor relief of piston ring land.Sedimentation is washed away and carried under one's arms to the external force such as ocean current, trend, storm tide, is formed
Sand-flour sand-mud mixes alternate landform.China coastal seas bank Development Engineering creates the engineerings such as embankment, breakwater and frequently encounters section
Among silty sand ground groove bigger, silt soft foundation is deep and in tidal current scour formation, the treatment of soft foundation referred to as in foundation trench.
The technology of blasting procedure processing Underwater Soft Foundation is widely used to harbour breakwater, reclaims fields from the sea, the engineerings such as shore protection,
Saving economic, guarantee safety etc. has significant advantage.But the treatment of soft foundation in foundation trench, especially big cross section, deep base
In terms of the treatment of soft foundation of slot, traditional solution or be sea wall early construction design link avoid such landform or
Heavy excavation is carried out to mud basis using traditional method.
What processing Muddy Soft Foundations construction application was more is the method for compacting mud by explosion displacement or directional-sliding at present.But it is right
In this complicated and universal sea wall environment of big cross section depth foundation trench silt soft foundation, previous compacting mud by explosion construction technology is often difficult to
Reach design requirement or the inadequate levee body of replacement depth is bottomed is unsatisfactory for design requirement or the bottomed width of levee body platform is inadequate, this is just
New technology is needed to handle the sea wall Construction Problems of big cross section depth foundation trench Silty soft foundation.
Invention content
To solve the above-mentioned problems, the purpose of the present invention is handling the defect of soft base for above-mentioned explosion method, one kind is provided
The new method for big cross section embankment breakwater depth foundation trench Silty soft foundation, it is more than 20 that this method, which is applicable in levee body section width,
Rice, length are more than 30 meters, levee body axis is vertical with foundation trench axis or oblique, silt depth are more than 10 meters of deep foundation trench silt soft
Base.
To achieve the above object, the technical solution adopted by the present invention is：Big cross section embankment breakwater depth foundation trench silt soft foundation
The method of explosion method processing
Include the following steps：
Step 1：Prefabricated formation length is 30-50 meters of narrow dikes, will be in the narrow dike explosion throwing to deep foundation trench silt soft foundation；
Step 2：Jackstone material is mended to the narrow dike and is increased, until meeting predetermined value HLevee body thickness, in the narrow dike two of throwing in place
It is quick-fried that side cloth medicine carries out side；
Step 3：Jackstone material is mended to the narrow dike to widen to both sides, then carries out secondary side in the levee body both sides cloth medicine of narrow dike
It is quick-fried；
Step 4：Step 3 is repeated until reaching levee body design width value L；
Step 5：Repetition step 1-4 carries out next section of the quick-fried of levee body and fills out construction, until completing whole levee body.
Further, the step 1 the specific steps are：
Step 1.1：Determine that the width of narrow dike, width are controlled in 10-12m；
Step 1.2：The throwing elevation for determining narrow dike, the not upper water of levee body, ensures that vehicle safety is logical when needing to meet high tide level
Row, quick-fried rear levee crown are no more than design altitude, throwing elevation 0.5m on design high-water；
Step 1.3：Determine that the throwing drilling depth of narrow dike, throwing drilling depth are controlled in 4-8m；
Further, the benefit in the step 2 is thrown elevation and should be met：
H1+H2≥H0 (1)
In formula：H1For throwing height；H2To mend the height thrown；H0For levee body section design height.
Further, both sides are widened in the step 3, and quick-fried width of filling out should be controlled in 4-6m every time, final entirety throwing width
Following formula should be met：
L=L0–K1H1–A (2)
In formula：L is throwing width；L0For berm width or bottomed width；H1For the above stone riprap height in mud face；K1For mud
The above stone riprap slope ratio in face, K1=0.8~1.0；A-correction value, A=0~2；
Further, heretofore described blasting parameter design should meet following requirement：
(a) line dose is calculated according to the following formula：
q'L=qoLHHN
HN=HM+HB
Q' in formulaL- line cloth dose (kg/m)；
qo- explosive specific charge (kg/m3), i.e., the quick-fried dose except needed for unit volume mud takes 0.1~0.3kg/m3；
LH- blasting discharging sedimentation rockfills the horizontal distance (m) once promoted, takes 4~8m；
HN- it is included in the mud overall thickness (m) of mud packet thickness；
HM- design displacement silt depth (m)；
HB- mud packet thickness (m).
(b) the become silted up dose that rockfills of onepull row is calculated as follows：
Q=q'L LL
The dose (kg) that rockfills that becomes silted up is arranged in Q-onepull in formula；
q'L- line cloth dose (kg/m), i.e., the dose being distributed in unit cloth medicine length；
LLThe cloth medicated thread length (m) that-blasting discharging sedimentation rockfills.
(c) dynamite quantity per hole is calculated according to the following formula：
Q1=Q/m
M=LL/(a+1)
Q in formula1- dynamite quantity per hole (kg)；
The dose (kg) that rockfills that becomes silted up is arranged in Q-onepull；
Cloth medicine hole count of m-；
LLThe cloth medicated thread length (m) that-blasting discharging sedimentation rockfills；
A-pack spacing (m), takes 4-6m.
(d) pack takes 0.45~0.55H in mud face length of embedment belowN。
The present invention further improvement lies in that, the cloth medicine pack spacing a of step (1) described explosion takes 4-6m；
The present invention further improvement lies in that, the quick-fried cloth medicine pack spacing a in step (2) (3) described side takes 5m；
The invention has the advantages that due to the adoption of the above technical scheme, method of the invention can effectively solve the problem that big disconnected
The problem of face depth foundation trench bottomed depth of underwater sludge soft base explosion levee body or bottomed short of width；Can be that underwater sludge soft base carries
Supply and discharge silt channel effectively solves the displacement of big cross section depth foundation trench mud and is not thorough, dike cardiolith bottomed situations such as design requirement is not achieved.
