Description
Technical field
The utility model belongs to field of road, relates to river construction, is specifically related to the construction equipment of cofferdam, a kind of river water conservancy diversion.
Background technology
When wearing river and crossing bridge engineering construction under construction of tunnel, pipe works, need to carry out cofferdam water conservancy diversion measure to river, to give tunnel, bottom and pipeline construction, or top bridge construction provides a good working environment, the water content of the upper soil horizon of tunnel and pipeline is reduced, reduce milliosmolarity under river, or be that Bridge Pile Foundation Construction provides good working environment by orderly draining, reduce the unordered draining in river to the impact caused of constructing.
The method of conventional cofferdam water conservancy diversion is mainly: cutout, employing riverbed are laid waterproof blanket, bottom arranges cover plate and excavated diversion channel four kinds of methods.Adopt the construction method of cutout, its main working measure is, arranges cofferdam and upper river water is cut off, reduce dirty come the water yield, thus reduce milliosmolarity under river, for correlation engineering provides a larger work plane.Its construction method is simple, but is the principal works problem that it is tackled to the process of upland water.And can relate to more multidisciplinary to the process of upper reaches water, its treatment measures engineering quantity and engineering cost are comparatively large, and can affect the excretion of periphery surface water in rainy season and periphery sewage.
According to the method for laying waterproof blanket bottom river, its working measure is mainly, half range construction about river dams point, build U-shaped cofferdam, cofferdam internal water accumulation and mud are cleaned out, then bottom riverbed, lays waterproof blanket, treat that waterproof blanket carries out recovery water flowing after laying.Adopt this construction method that the engineering quantity of laying will be caused larger, required construction period is longer.
When adopting bevelling lid excavation construction method, in the dry season, the construction of left and right half range branch is carried out to river, build U-shaped cofferdam, cofferdam internal water accumulation and mud are cleaned out, cover plate is laid in riverbed, to utilize cover plate as support, the earthwork, construction tunnel or pipeline configuration under excavation lid digs cover plate.When adopting the construction of cover plate method, need cover plate amount large, require higher to cover plate support, construction workload is comparatively large, and operating expenses also will increase accordingly.
Excavation diversion channel scheme is then the one or both sides excavation diversion channel in river, lays waterproof blanket, then builds cofferdam at upper river, river is introduced diversion channel bottom diversion channel.When adopting this kind of construction method, because one or both sides, river need to carry out diversion channel excavation, required construction working face will increase further, and the position often inconvenient construction carrying out diversion channel residing for river.
In sum, the major defect of existing construction method is that required engineering cost is comparatively large, and construction workload increases, construction period is longer, causes construction working face comparatively large to the underutilization in existing riverbed, larger on surrounding enviroment impact, to river water undertreatment, water treatment expense is caused to increase.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is, provides the construction equipment of cofferdam, a kind of river water conservancy diversion, to ooze the impact on river bottom solum under reducing river, under wear tunnel, river or pipeline construction provides a kind of good working environment.Reduce channel flow scope for the river bridge construction that collapses provides a larger construction working face simultaneously.There is provided a kind of good working environment not only to the engineering construction of engineering in river influence basin by this cofferdam parallel works, reduce the engineering cost of cofferdam construction simultaneously, reduce the engineering quantity of ancillary works, shorten construction period, for principal works construction is raced against time.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to be achieved:
The construction equipment of cofferdam, a kind of river water conservancy diversion, comprise the cofferdam be arranged on for a pair for the river that dams on riverbed, a pair described cofferdam is provided with the mozzle of through cofferdam, makes the river of a cofferdam upstream import another cofferdam downstream from mozzle;
The face that described cofferdam contacts with river is provided with one deck waterproof blanket;
Described mozzle outer wall is coated with one deck waterproof blanket.
The utility model also has distinguishes technical characteristic as follows:
Described cofferdam is divided into outside to work out gunnysack filling cohesive soil pile, cohesive soil core-wall and inner side gunnysack and fill cohesive soil pile successively from the outside contacted with river to inner side.
Described mozzle is a pair mozzle.
Described mozzle is arranged on bottom cofferdam and makes mozzle against riverbed water conservancy diversion river on vertically.
Described mozzle is upwards arranged on the position of cofferdam both sides near river levee in level, for disperseing river to the pressure of cofferdam.
Being provided with cushion coat between described mozzle and river levee, being applied to power in cofferdam horizontal direction for disperseing mozzle.
Described cushion coat is the gunnysack that cohesive soil is housed.
Described waterproof blanket comprises one deck basic cloth, and basic cloth is provided with one group of packaging bag, packaging bag is built with sodium bentonite.
The utility model compared with prior art, has following technique effect:
(A) the cofferdam parallel works that provides of the utility model, easy construction, simply, practical, material requested very easily obtains, and has fewer environmental impacts, and mozzle and cofferdam gunnysack can reuse, and has more manifested the requirement of energy-saving and emission-reduction.
(B) cofferdam provided by the utility model parallel works makes full use of riverbed, utilize mozzle by have water in order by Effects on Engineering region, reduce the runoff in this section of river simultaneously, reduce under river and ooze.Due to the protection with mozzle, the impact that the orderly water vent in river is not constructed.And do not affect the excretory function in river, the impact of periphery life is reduced.
(C) device provided by the utility model is for the water treatment measures of upstream, cofferdam and mozzle are combined, under the effect not changing discharge of river, adopt orderly draining, what reduce that process upland water needs with multidisciplinary communication is loaded down with trivial details, reduce the disposal cost to upland water, reach good effect.
