Abstract
The utility model discloses a cofferdam steel sheet pile construction guiding structure in deep water, which is characterized in that in an outer-ring steel protective tube in a cofferdam, a guide bracket support is fixedly welded onto the outer-ring steel protective tube toward one side of a steel sheet pile. A guide block is fixedly welded on the guide bracket support according to an inserting position of the steel sheet pile, after the guide block finishes the guide of the inserting of the steel sheet pile, the guide block is dismounted from the outer-ring steel protective tube and then fixedly arranged on the steel protective tube through a waling bracket support to form a waling. The cofferdam steel sheet pile construction guiding structure in deep water enables the construction of cofferdam steel sheet piles in deep water to be accurately guided, ensures project progress, and improves project quality.
Description
Technical field
The utility model relates in a kind of deep water the cofferdam steel sheet pile to be inserted and beats guide frame, and more specifically saying so is applied in the deep water occasion, makes the accurately slotting guide frame of beating of cofferdam steel sheet pile.
Background technology
For the cushion cap foundation ditch cofferdam construction of land, the method that adopts usually is after measurement is put a little, directly is placed in as fairlead through the Two bors d's oeuveres i iron and measures the slotting Larsen steel sheet pile of beating that leads on the sideline; The Larsen steel sheet pile insert beat accomplish after, directly with fairlead as waling, and with waling through the bracket welded and installed on the Larsen steel sheet pile, excavation of foundation pit can be carried out with digging machine subsequently in formation foundation ditch cofferdam in the foundation ditch cofferdam.
But,, can't accurately implement the Larsen steel sheet pile and insert and beat because of can't be in deep water directly placing fairlead, causing for the deepwater work environment.Such as the Yellow River, Shan, the domestic Shanxi of China grand bridge; The engineering address is that Shaanxi Province and intersection Yumen, Shanxi Province mouth are to section the Yellow River, Tongguan; Bridge axis and flood main flow angle are about 83 °; Main bridge cushion cap major part all is in deepwater regions, and the cushion cap foundation ditch has adopted steel sheet-pile cofferdam just, the open report that accurately leads for steel sheet pile in the not relevant operating environment in the prior art.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provides in a kind of deep water the cofferdam steel sheet pile to insert and beats guide frame, so that the inserting the process of beating and can accurately be led assurance programming, and raising workmanship of cofferdam steel sheet pile in the deep water.
The utility model adopts following technical scheme for the technical solution problem:
Steel sheet pile slotting characteristics of beating guide frame in cofferdam are on the outer ring steel casing in the cofferdam in the utility model deep water; Be on the steel casing of said outer ring towards the fixing welding guiding of a side of steel sheet pile angle-table bracket; On said guiding angle-table bracket, press inserting of steel sheet pile and make fixed-site welding guide pad, said guide pad is inserted and is played the dismounting and transfer to be fixedly installed on through the waling angle-table bracket and constitute waling on the steel sheet pile on the steel casing of outer ring of guiding back accomplishing steel sheet pile.
Steel sheet pile slotting design feature of beating guide frame in cofferdam also is in the utility model deep water: said guiding angle-table bracket and the waling angle-table bracket same member for migrating mutually.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model is to be the basis with steel casing in the cofferdam of accomplishing construction, and the steel sheet pile guide frame is set, and makes inserting to beat and being able to accurate guiding of cofferdam steel sheet pile in the deep water.
2, guide pad is rationally utilized member itself after accomplishing guiding then be fixedly welded on and promptly constitute waling on the steel sheet pile on the one hand in the utility model, also makes the setting of waling be able to simplification on the other hand.
3, guiding angle-table bracket and the waling angle-table bracket same member for migrating mutually in the utility model is made the best use of everything member, avoids waste.
Description of drawings
Fig. 1 is a cofferdam structure sketch map in the utility model;
Fig. 2 is provided with structural representation for guide pad in the utility model;
Fig. 3 is for guide pad in the utility model then be set to the waling structural representation;
Label among the figure: 1 steel sheet pile; 2 outer ring steel casings; 3 guiding angle-table brackets; 4 guide pads; 5 waling angle-table brackets; 6 cushion cap boundary lines; 7 steel platforms; 8 waters surface.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3; To insert and to beat guide frame be on the outer ring steel casing 2 in the cofferdam to the cofferdam steel sheet pile in the present embodiment deep water; Be on the outer ring steel casing 2 towards the fixing welding guiding of a side at steel sheet pile 1 place angle-table bracket 3; Press inserting of steel sheet pile 2 on the angle-table bracket 3 in guiding and beat fixed-site and weld guide pad 4, constitute with this that steel sheet pile is slotting beats guide frame, as shown in Figure 2;
Accomplishing after inserting of steel sheet pile 1 beat guiding, guide pad 4 is removed on outer ring steel casing 2, transfer with the angle-table bracket 3 that leads guide pad 4 to be welded on the relevant position of steel sheet pile 1 as waling angle-table bracket 5, constitute the waling structure with this, as shown in Figure 3;
Shown in Fig. 1, the distance of the outward flange of outer ring steel casing 2 and cushion cap boundary line 6 is 40cm in the present embodiment, with the inside edge of steel sheet pile be 140cm; The end face that is positioned at the steel platform 7 of a side is that guiding angle-table bracket 3 is positioned at the water surface more than 8 on the high position of guiding angle-table bracket 3 above 230cm.
In the concrete construction, need on peripheral steel casing 2, hang plug-in cage, as the job platform of manual work welding, must adopt full weld between guiding angle-table bracket 3 and the outer ring steel casing 2, to guarantee weld strength; The guide pad 4 that constitutes with Two bors d's oeuveres I40b i iron must accurately be placed on the guiding angle-table bracket; Accurately locate with the auxiliary loop wheel machine of manual work; After accomplishing, the location is fixedly welded on the guiding angle-table bracket; Guarantee that the plug in guide pad that touches when beating of steel sheet pile is unlikely to make guide pad to produce displacement, and then it is accurate as the position of waling to guarantee that steel sheet pile is inserted the accurate and later stage guide pad of beating the position.
Claims (2)
1. the cofferdam steel sheet pile is inserted and is beaten guide frame in the deep water; It is characterized in that on the outer ring steel casing (2) in the cofferdam; Being in said outer ring steel casing (2) goes up towards the fixing welding guiding of a side of steel sheet pile (1) angle-table bracket (3); Go up by inserting of said steel sheet pile (1) at said guiding angle-table bracket (3) and to make fixed-site welding guide pad (4), said guide pad (4) accomplish steel sheet pile (1) insert beat the guiding back from the outer ring steel casing (1) go up and remove and then be fixedly installed on upward formation waling of steel sheet pile (1) through waling angle-table bracket (5).
