Abstract
The utility model discloses a sand cushion sand-blocking reclamation dam, which consists of sand gravel and is positioned around the construction position in which a sand cushion is ready to be laid.The sand gravel replaces the bagged sand in the prior art to eliminate the working procedure of manual sand loading, and the sand gravel can be dumped by machinery, and thereby the work efficiency isimproved, the construction time limit is greatly shortened, the cost is reduced, and simultaneously, the defect that the reclamation dam is easy to fall over due to the instability of the bagged sandis overcome to ensure the construction progress and quality.
Description
Technical field
The utility model relates to the civil construction field, and low bank between fields is enclosed in the sand cushion sand block that especially relates in the mole basic engineering construction field.
Background technology
Mole is to be defence wave, silt, ice slush invasion, form one and shelter the needed hydraulic structure in waters or other facilities, usually jetty or the unconnected offshore breakwater that is connected with bank by one, two roads formed, or form jointly by jetty and offshore breakwater, often there is one or several mouthful door in the waters of shielding for the ship turnover.It is to build when the natural conditions of building the port can not satisfy its needs of sheltering the waters; make and shelter the waters the enough depth of water and the water surface are stably arranged; can guarantee the safety of mooring, loading and unloading and the navigation of boats and ships; can protect the various equipments and the facility in harbour again, be the important component part of harbour engineering.
As the sand cushion of mole ground foundation construction under water the stable important function that played to mole.Because sand cushion is to construct under water, because water currents, sand cushion runs off serious, and very difficult assurance reaches design section.Prior art is packed sand throwing and filling around the construction location of preparing the laying sand cushion normally, and the sand cushion that makes throwing fill out falls within two and encloses between the low bank between fields, to reach design section.Owing to packed sand filling trouble, and can not throw with machinery and fill out, operating efficiency is very low, and simultaneously, packed sand body is long-pending bigger, and it is wayward to packed sand when throwing manually to loose, and makes packed sand enclose low bank between fields easily and forms the discontinuous low bank between fields that encloses at the bottom, influences workmanship.And the sand amount of packed sand filling when filling has a significant impact enclosing the low bank between fields quality, when the sand amount of filling is too many, packed sand is too full, be shaped as elongated cylindrical, be not easy control at the water-bed utmost point and enclose the low bank between fields shape, the cylindrical of packed sand makes that enclosing low bank between fields lodges easily simultaneously; When the sand amount of filling when very few, packed sand easily laminates at the bottom after throwing and filling out mutually, is difficult to control and encloses the low bank between fields shape equally, and very easily form discontinuous sand block at the bottom and enclose low bank between fields, influences workmanship.
Therefore being necessary to design a kind of sand cushion sand block encloses low bank between fields, overcomes the unstability and artificial the loosing of enclosing low bank between fields and easily forms discontinuous shortcoming of enclosing low bank between fields when throwing at the bottom.
The utility model content
The utility model proposes at the problems referred to above, and purpose provides a kind of sand cushion sand block at water-bed continous-stable and encloses low bank between fields.
For achieving the above object, the utility model is achieved through the following technical solutions:
Low bank between fields is enclosed in a kind of sand cushion sand block, and described sand block is enclosed low bank between fields and is made of rubble, is positioned to prepare to lay around the construction location of sand cushion.
Preferably, to enclose the section of low bank between fields be trapezoidal in described sand block.
Preferably, the upper topside width of described trapezoidal cross-section is 0.1m-1.0m.
More preferably, the upper topside width of described trapezoidal cross-section is 0.5m.
Preferably, described trapezoidal cross-section base angle is 30 degree-60 degree.
More preferably, the base angle of described trapezoidal cross-section is 45 degree.
Preferably, the described sand block height that encloses low bank between fields is higher than sand cushion top design absolute altitude.
Preferably, the diameter of described rubble is 2cm-7cm.
Owing to adopt rubble to replace the packed sand of prior art, saved the operation of manual dress sand, and rubble can be thrown with machinery and fill out, needn't manually loose as packed sand and throw, improved operating efficiency, shortened the construction period greatly, reduce cost, and avoided Sheng sand too much to make packed sand too full, form elongated cylindrical, be not easy control at the water-bed utmost point and enclose the low bank between fields shape, enclose low bank between fields easily lodging and contain that sand is very few and make packed sand throw to fill out after easily laminate mutually at the bottom, the low bank between fields shape is enclosed in very difficult control, and very easily form the shortcoming that low bank between fields is enclosed in discontinuous sand block, guaranteed construction speed and construction quality at the bottom.
Description of drawings
Fig. 1 encloses the schematic diagram of low bank between fields section for the sand cushion sand block.
Wherein, the 1-water surface, the 2-sand cushion, 3-encloses low bank between fields
The specific embodiment
With reference to Fig. 1, enclose low bank between fields 3 according to a kind of sand cushion sand block of the present utility model, described sand block is enclosed low bank between fields 3 and is made of rubble, is positioned at the position, sideline of preparing to lay sand cushion 2.It is trapezoidal enclosing the low bank between fields section.Last end face width is 0.1m-1.0m, is preferably 0.5m.The base angle of trapezoidal cross-section can be preferably 45 degree for 30 degree-60 degree.The rubble diameter can be 2cm-7cm.
Because sand cushion 2 is in the water surface 1 time construction, because water currents, sand cushion 2 runs off serious, and very difficult assurance reaches design section, therefore throw back-up sand bed course 2 before, throw in advance in the position, sideline of sand cushion to be constructed and to fill out the gravelly low bank between fields 3 that encloses.
Rubble is going out the stone terminal ship, adopt 600-1000t side's oceangoing ship or belt shipping to the job site, rock crushing dredger travels and sets the limit mark to the scene at design bed course side slope location interval 200m, throwing is filled out boats and ships and is carried out coarse positioning with reference to the limit mark, utilize gps satellite to be decided to be system then and determine position, detailed construction sideline, then, refute seat 1.2m with the side
3Backacter is thrown and is filled out or the construction in the position of belt ship.
When throwing was filled out, according to the utility model most preferred embodiment, the end face width was 0.5m on the low bank between fields section by enclosing, the base angle is 45 degree, the rubble diameter is the stone amount of 2cm-7cm calculating, and adopt excavator or belt ship to control by fixing a point, quantitatively throw and fill out rubble, reaching enclosing the low bank between fields section is trapezoidal purpose.
When filling out by the preferred embodiment throwing, the stability of enclosing low bank between fields is the highest, can certainly be 0.1m-1.0m by the last end face width that encloses low bank between fields, and the base angle is for being 30 degree-60 degree, and the stone amount of calculating is thrown and filled out.
Though describe the utility model in detail with reference to specific embodiments, it is pointed out that these embodiments only are used for understanding better the utility model.It will be apparent to those skilled in that under the situation that does not depart from spirit and scope of the present utility model, making some variations and revise on the basis of the foregoing description all is the scope that the utility model is protected.
