Abstract
The utility model relates to a double-sided steel formwork for underground continuous wall construction and aims to provide a double-sided steel formwork which has the characteristics of good reinforcement effect and convenience of construction. According to the technical scheme of the utility model, the double-sided steel formwork for underground continuous wall construction is characterized by comprising two slot plates; the cross sections of the two slot plates are shaped like [; the concave surfaces of the two slot plates are opposite to each other and separated by a plurality of supporting bars welded and fixed on the slot plates in parallel to keep a certain space; one end of the double-sided steel formwork in the width direction is provided with a tenon opening formed naturally by the edges of the two slot plates, and the other end is provided with an insertion tenon which is matched with the tenon opening and is inserted into the tenon opening; the insertion tenon is composed of two right-angle sides which are formed by extending and bending the edges of the two slot plates; and the outer edge of each right-angle side is bent towards the outside of the thickness direction of the slot plates.
Description
Technical field
The utility model relates to a kind of building operations equipment, in particular for the two-sided steel form of construction of diaphragm wall.
Background technology
Existing construction of continuous concrete wall is normally used certain device and facility, under the condition of mud off, through pore-creating (or) groove; Use materials such as direct pipe method fluid concrete again, the final continuous body of wall with certain antiseepage function, this conventional job practices of forming; Can't remove or remove halfway mud in the work progress, be easy to be involved in the concrete, antiseepage, the resistance to compression effect of the diaphragm wall that forms all had certain influence; In addition; Construction works is complicated, and Working Procedure Controlling is strict, is difficult to obtain desirable effect.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of two-sided steel form that is used for construction of diaphragm wall is provided, and this two-sided steel form should have that consolidation effect is good, the characteristics of easy construction.
The technical scheme that the utility model adopts is: a kind of two-sided steel form that is used for construction of diaphragm wall; It is characterized in that this two-sided steel form comprise two cross sections for " frid of [" shape, two frid concave surfaces are weldingly fixed on the support bar parallel spaced apart certain spacing on the frid relatively and through several; One end of the width of said steel form is the tenon mouth that two frid edges form naturally, and the other end is shaped on the plug tenon that can cooperate with this tenon mouth grafting.
Said plug tenon extends two right-angle sides that are bent to form by the edge of two frids and forms the outer lateral buckling of the past frid thickness direction in the outer of each right-angle side.
Said support bar is weldingly fixed on the frid concave surface; Wherein several support bars on the left side are weldingly fixed on the left side edge of frid, are positioned at several support bars on frid right side and the right edge edge of frid and keep at a certain distance away to form described tenon mouth.
The operating principle of the utility model is following:
1, two-sided steel form is pressed in the soil with Static pressure pile driver one by one, and mutual hasp forms continuous arrangement between the adjacent two-sided steel form; Steel form thickness and length and width are fixed according to geology and foundation depth;
2, wash away the soil in the two-sided steel form with giant, and with slush pump mud is siphoned away, absolute altitude at the bottom of the designing requirement is washed away in circulation; Mud can be used as through the post precipitation clear water and washes away one of water source, and the mud that precipitates is abandoned outward;
3, in two-sided steel form, pour into the concrete of design label, and vibration compacting; Get final product after waiting to the cement solidifies.
Like need anchor cable (bar) hole is set on concrete wall, can when pallet, gives and establish sleeve pipe or other device.
The beneficial effect of the utility model is: after adopting this two-sided steel form; Mud in the work progress can access slap-up removing; And can not be involved in again in the concrete; Thereby significantly improved the intensity of concrete intensity and diaphragm wall, and watertightness performance and waterproof effect all have significantly and promote; In addition, easy construction and noiselessness have the advantages that to support with the unification of structure two walls.

The specific embodiment
A kind of two-sided steel form that is used for construction of diaphragm wall; This two-sided steel form comprises that two cross sections are the " frid 1 of [" shape; Two frids link together through the support bar 2 that several are weldingly fixed on the frid, and concave surface is relative and the parallel spaced apart certain spacing.One end of the width of said steel form is the tenon mouth 5 that two frid edges form naturally, and the other end is shaped on the plug tenon 6 that can cooperate with this tenon mouth grafting; The structure of this plug tenon is: the outer that the edge of two frids extends 3, two right-angle sides of two right-angle sides that are bent to form is folded to rightabout (the outer lateral buckling of past frid thickness direction respectively) respectively, has formed described plug tenon thus.
Said support bar 2 is weldingly fixed on the frid concave surface; Wherein several support bars on the left side are weldingly fixed on the left side edge (shown in Figure 1) of frid, and several support bars on frid right side and the right edge of frid are along keeping at a certain distance away to be used to form described tenon mouth 5.
In addition, be arranged in several support bars of frid the same side, also have certain spacing in twos between the adjacent supports bar 2, be beneficial to the mobile diaphragm wall that makes of concrete and form an integral body; This spacing can confirm as required that recommending spacing is 1 meter.
During making, the right edge of frid can be an integral body along prolonging and carrying the right angle that is bent to form on this edge, and disposable punching out forms when making.
The utility model is particluarly suitable for basement (foundation ditch) construction (except that soil property and sand gravel more than 3 types) that the degree of depth is no more than 20 meters.
