Background

The diaphragm wall is mainly applied to diaphragm wall sheet pile wharf structures and subway station supporting structures, the diaphragm wall concrete super-grouting height is generally about 0.5-0.8 m according to the diaphragm wall construction process, and diaphragm wall super-grouting concrete can wrap diaphragm wall anchoring ribs to form large holding force. Before the construction of the upper structure of the diaphragm wall, the diaphragm wall super-poured concrete and the bonding part of the anchoring ribs need to be peeled off, and then the diaphragm wall super-poured concrete is hung. The traditional construction method for stripping diaphragm wall super-poured concrete and anchoring ribs is manual air pick chiseling, and the method has the following defects: a. the anchoring ribs are easy to be damaged by meat biting, repeated bending and the like in the manual chiseling process, so that the bending resistance of the anchoring ribs is reduced; b. the traditional chiseling method needs a large amount of professional special work types, the chiseling efficiency of the diaphragm wall super-filled concrete is low, and the working procedure becomes a key factor for restricting the construction period; c. a large amount of noise and dust are generated in the process of chiseling the diaphragm wall super-filled concrete, so that the civil disturbance event and the environmental pollution are easy to occur, and the safe and civilized construction is not facilitated; the method is characterized in that the method is used for excavating the diaphragm wall super-irrigation concrete for a long time, workers are prone to pneumoconiosis and general vibration occupational diseases, the occupational health of the workers is influenced, and the method is contrary to the people-oriented idea of the country; d. the cost of the drilling personnel for the ground connecting wall super-filled concrete is high.

Disclosure of Invention

For solving the above-mentioned shortcoming, the utility model aims at providing a protect wall anchor muscle even with the ground, can avoid the ground even super-filled concrete of wall to wrap up in the bond of anchor muscle, reduce the ground even wall excavation back ground even the super-filled concrete of wall chiseling the construction process, solved traditional artifical chiseling and removed the ground even the super-filled concrete of wall and easily cause the protection architecture who destroys the difficult problem to the anchor muscle.

In order to achieve the above object, the utility model adopts the following technical scheme: a diaphragm wall anchoring bar protection structure, comprising: the anchor muscle row that the reinforcing cage in even wall, even wall in the ground and the relative both sides limit in even wall upper portion in the ground formed by a plurality of anchor muscle is arranged, the anchor muscle row forms the outer wall that holds even wall super-filled concrete, the anchor muscle row is equipped with the protection device of anchor muscle, the protection device of anchor muscle is including corresponding the planking, the inner panel that set up in anchor muscle row both sides respectively and the anchor nail of connecting planking, inner panel.

The outer plate and the inner plate are respectively and correspondingly provided with a plurality of grooves matched with the anchoring ribs, and the grooves on the outer plate and the inner plate mutually form anchoring holes for containing the anchoring ribs.

The cross section of each groove is semicircular, the two semicircular grooves form a circular anchoring hole, and the diameter of the circular anchoring hole is 2-5mm larger than that of the anchoring rib.

Two connecting anchors are arranged between the outer plate and the inner plate.

And oblique angles are arranged at the contact positions of the outer plate, the inner plate and the diaphragm wall.

The angle of the bevel is 30-45 degrees.

The utility model has the advantages that: the plate body of the protection structure is made of corrosion-resistant materials such as PE or PP, the anchoring ribs are isolated from the diaphragm wall super-poured concrete through the inner plate and the outer plate, the diaphragm wall super-poured concrete loses bond force on the diaphragm wall anchoring ribs, the aim that diaphragm wall super-poured concrete can be hung and removed without chiseling diaphragm wall super-poured concrete is achieved, the protection structure is simple to manufacture, and factory streamlined production is facilitated.

Detailed Description

The following describes the protection structure of the ground wall anchoring rib according to the present invention with reference to the accompanying drawings.

As shown in fig. 1 to 4, the utility model discloses a ground is wall anchor muscle protection architecture's design thought is that utilize anchor nail 3 to fix planking 1 and inner panel 2 on anchor muscle 7, realize keeping apart anchor muscle 7 and ground even wall super-grouted concrete 6, stop ground even wall super-grouted concrete 6 and wrap up in to anchor muscle 7's bond to realize ground even wall super-grouted concrete and exempt from the purpose that chiseling can hang and remove, improved the efficiency of construction under the circumstances of guaranteeing anchor muscle 7 not chiseling the in-process destruction by ground even wall super-grouted concrete 6, practiced thrift the cost of labor, be favorable to the environmental protection construction.

The local continuous wall anchoring rib protection structure comprises an outer plate 1, an inner plate 2 and an anchor 3; the outer plate 1 comprises an outer plate surface W1, an outer plate rib W2, an outer plate groove W3, an outer plate anchoring hole W4 and an outer plate bevel W5; the inner plate 2 comprises an inner plate surface N1, an inner plate rib N2, an inner plate groove N3, an inner plate anchoring hole N4 and an inner plate bevel N5.

The cross sections of the outer plate groove W3 and the inner plate groove N3 are semicircular, and the diameter of the outer plate groove W3 and the inner plate groove N3 is 2-5mm larger than that of the anchoring rib 7; in order not to influence the lifting of the concrete to the sediment in the concrete pouring process, the angles of the outer plate bevel angle W5 and the inner plate bevel angle N5 are preferably between 30 degrees and 45 degrees.

The utility model discloses a ground is wall anchor muscle protective structure function is realized like this:

1. after the ground-connected wall reinforcement cage 4 is manufactured, the outer plate 1 is placed on the outer side of the ground-connected wall reinforcement cage 4, the inner plate 2 is placed on the inner side of the ground-connected wall reinforcement cage 4, and the anchor bolts 3 connect the outer plate 1 and the inner plate 2 together through the outer plate anchoring holes W4 and the inner plate anchoring holes N4.

2. Planking 1 and inner panel 2 are by anchor 3 anchor back, and planking board rib W2 and inner panel board rib N2 contact, and including planking recess W3 and inner panel recess N3 wrapped up anchor muscle 7, finally protected even wall anchor muscle 7 with ground, avoided even wall super-filled concrete 6 to wrap up in the holding of anchor muscle 7, even wall anchor muscle protection architecture installation is accomplished.

3. Put the groove under the wall reinforcement cage 4 that will install even wall anchor muscle protection architecture, carry out even wall concrete pouring, after even wall concrete reaches excavation strength, with even wall super-filled concrete 6 excavate, demolish anchor nail 3 earlier, demolish planking 1 again, then hang even wall super-filled concrete 6 and remove, reduced even wall 5 excavation like this and even wall 6 chisel of even wall super-filled concrete and removed the construction process, solved traditional artifical chisel and removed even wall super-filled concrete 6 and easily caused the difficult problem of destruction to the anchor muscle.

The ground is wall anchor muscle protection architecture even notices following main points in the use:

1. the protective structure should have certain rigidity and strength to meet the requirements of field installation, hoisting and concrete pouring;

2. the protection structure should be far away from a fire source and a high-temperature area in the processes of storage, transportation and use, so as to prevent thermal deformation.
