Description

A kind of can explosion dyke for take off mouthful flood diversion

Technical field

This utility model belongs to the explosion flood diversion technical field of engineering explosion, a kind of for taking off mouthful flood diversion Can explosion dyke.

Background technology

As the important component part of rivers and lakes Flood Control System, dyke building controlling flood, irrigate, supply water, shipping, water are protected Etc. aspect bring huge society, economy and environmental benefit, the development of the national economy and social safety play huge work With.In the high flood unusual time, can retrain, when upland water exceedes this section dyke, the discharge passed through, for avoid being likely to occur Unfavorable situation, need to carry out in a planned way flood diversion crevasse to exceeding the section safety discharge flood that exceeds the quata, i.e. the flood that exceeds the quata be imported Flood storage areas planned in advance.Flood diversion method conventional in engineering is that dike technology is broken in explosion, has construction dike high-efficiency precision quick, broken Accurate feature.

Existing explosion is broken dike arrangement and method for construction and is generally solid explosive concentrated charge explosion, sees Fig. 7, and its operation sequence is for opening Dig coyote hole, powder charge, wiring, detonate, not necessarily detonate after powder charge.Except the flood diversion dyke on the important location of only a few may be reserved Having outside coyote hole, generally, coyote hole is by manually excavating with instruments such as army banjo, Luoyang Spade, ladle temporarily.Owing to broken dike calls time in advance Short, severe operational environment, whether breaking dike and affected by the factor such as weather, magnanimity, it is scarce that interim excavation coyote hole is primarily present two big technology Fall into: one is that excavation operating speed is relatively slow temporarily, and the broken dike of impact is carried out in time；Two is that concentrated charge coyote hole volume is relatively big, easily drops Low dyke intensity.

Summary of the invention

The purpose of this utility model be to provide a kind of for take off mouthful flood diversion can explosion dyke, with solve excavate coyote hole temporarily Operating speed is slow, reduce the defect of dyke intensity.

A kind of can explosion dyke for take off mouthful flood diversion, it is characterised in that:

Including dyke explosion section, dyke explosion section is provided with multiple boring being arranged in rows, and is provided with pre-buried dress in each boring Medicine device, each pre-buried means for loading includes for the powder charge pipeline of explosive and is located at the openable of powder charge pipe ends Duct sealing lid；It is provided with carn at the embedment of each pre-buried means for loading.

The inclination angle of described boring is 10～40 °；Array pitch and the pitch-row of boring are 2～4m, go up most hanging down of row hole drilling and levee crown Straight distance is 1～3m.

The two ends of described dyke explosion section are provided with deep-mixed pile.

Of the present utility model a kind of it be applicable to explosion and break dike and take off the pre-buried means for loading of mouthful flood diversion, including for explosive Powder charge pipeline, described powder charge pipe ends is provided with openable duct sealing lid.

This new device is embedded in dyke in advance by drillhole blasting steel for shot mode, the conduct when needs carry out flood diversion task Coyote hole uses.Primarily serving the purpose of of powder charge pipeline is embedded in dyke formation coyote hole.Duct sealing lid act as close powder charge Pipeline, it is to avoid subsoil water enters closed conduct with impurity when dyke is properly functioning, in order to avoid explosive is subject to when dike powder charge is broken in explosion Tide.

As preferably, described powder charge pipe end and duct sealing lid are provided with the screw thread complemented one another, duct sealing lid In the way of screw thread socket, powder charge pipe ends is closed.

As preferably, described duct sealing lid is flat mouth lid, and powder charge pipe end is the flat mouth supporting with duct sealing lid End, powder charge pipe ends is closed in the way of directly socket by duct sealing lid.

As preferably, described powder charge pipeline is PVC plastic material, its diameter 25～150mm, and they are a length of 10～50m years old；Institute Stating duct sealing lid is plastics or quality of rubber materials, and its diameter is than powder charge pipeline big 1～2cm.

In this utility model, the thickness of powder charge pipeline, hardness are commonly used pvc pipe with engineering and are as the criterion；The length of powder charge pipeline is pressed Explosion design is chosen, generally 10～50m.

The using method of the pre-buried means for loading of this utility model is:

Step 1, at dike construct or normal operating phase, breaks dike explosion design according to flood diversion and requires boring, inclination angle 10～ 40 °, array pitch and pitch-row take 2～4m, first row boring vertical dimension levee crown 1～3m；Step 2, by the pre-buried powder charge of sealing two ends In device embedment boring, pipeline upper end port embedment dyke 20～80cm, at embedment, stack soil stone be marked, convenient broken dike Time find pipeline carry out powder charge, simultaneously protective conduit；Step 3, needs to carry out explosion and breaks dike when taking off mouthful flood diversion task, by step 2 Mark search out pre-buried powder charge plumbing installation, open end closure on it, in pipe, carry out blast with linear charges powder charge, form explosion Networking；Step 4, receives networked detonation after explosion order.

Above-mentioned steps must use dual fail-safe detonate circuit during broken dike, generally by electric initiating circuit as main detonating line Road, primacord or the detonator circuit that detonates detonates circuit as pair, two lines road ignition and detonation simultaneously.

Of the present utility model a kind of for take off mouthful flood diversion can the advantage of explosion dyke be:

1. this utility model dyke is the most pre-buried when dyke is properly functioning, receive explosion break dike order thing can be rapid Powder charge, explosion, efficient quick；

2. powder charge conduit volume is less, less to dyke intensity effect.
