After the bamboo chip cage is placed in the stress release hole, the U-shaped bayonets can be used as the radial and tangential constraints of the bamboo chips, the positions and the intervals of the bamboo chips cannot be changed, effective support for the stress release hole is formed, and the hole forming quality is guaranteed.

Description

Bamboo chip cage for preventing stress release hole from collapsing

Technical Field

The utility model relates to the technical field of building engineering pile foundations, in particular to a stress release hole collapse prevention bamboo chip cage.

Background

The stress release hole is an important measure before piling, and can prevent surrounding buildings from being influenced in the piling process. The most important process requirement of the stress release hole is to ensure that the hole does not collapse after the hole is formed and prevent the failure of the stress release hole. The conventional method is to arrange bamboo chips into a circle, use stirrups as a restraint mode, fix the bamboo chips and the stirrups by binding wires, and finally form a bamboo chip cage. However, in engineering practice, the bamboo chips are easily separated from the stirrups, the distance between the bamboo chips is unstable, and the local gap is too large, so that the pore-forming quality of the stress release holes cannot be ensured.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a stress release hole collapse prevention bamboo chip cage, which aims to ensure that the distance between bamboo chips is not changed, the connection between stirrups and the bamboo chips is reliable and stable, and the phenomenon of hole collapse is avoided.

The technical problem of the utility model is mainly solved by the following technical scheme: the utility model provides a stress release hole bamboo chip cage of preventing collapsing, includes a plurality of bamboo chips and at least one hoop muscle circle, the hoop muscle circle outside is equipped with a plurality of U type buckles along circumference, the width of U type buckle is not less than the width of bamboo chip for the bamboo chip can inlay in the U type buckle.

Preferably, the stirrup ring is composed of a plurality of stirrup segments.

Preferably, two ends of each stirrup section are bent outwards respectively, and two adjacent stirrup sections are overlapped and welded with each other, so that the bent parts at the ends of the stirrup sections form the U-shaped buckles.

Preferably, the stirrup sections are welded in a staggered manner from top to bottom in sequence.

Preferably, the bent parts at the two ends of the stirrup section are positioned on the same plane.

Preferably, the bamboo chips are bound in the U-shaped buckles through binding wires.

Preferably, the length of the bent part at the end part of the stirrup segment is 1-2.5 cm.

Preferably, the width of the U-shaped buckle is equivalent to the width of the bamboo chips.

Compared with the prior art, the utility model has the advantages that: the utility model provides a novel anti-collapse bamboo chip cage with stress release holes, which can be used for manufacturing stirrup sections in advance according to the size of the actual stress release holes and performing welding connection to form U-shaped bayonets for placing bamboo chips. After the stress release hole is placed in the bamboo chip cage, the U-shaped bayonet can be used as the radial and tangential restraint of the bamboo chips, the positions and the intervals of the bamboo chips cannot be changed, effective support for the stress release hole is formed, and the hole forming quality is guaranteed.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further specifically described below by way of embodiments in combination with the accompanying drawings.

Example (b): a bamboo chip cage for preventing a stress release hole from collapsing is shown in figures 1-6, and in the embodiment, the bamboo chip cage is composed of a plurality of bamboo chips 1 and a stirrup ring 2, the stirrup ring 2 is a circular component formed by welding a plurality of stirrup sections 4, and the stirrup sections 4 are formed by bending steel bars.

When the bamboo chip cage in the embodiment is manufactured, the circumference of the stress release hole is divided into a plurality of circular arcs according to the diameter of the stress release hole and the design requirements of drawings, and the length of each circular arc is calculated. After the bending length (such as 2cm) of the two ends is reserved, steel bar blanking is carried out, the steel bar is bent according to the diameter of the stress release hole, the two ends of the steel bar are reversely bent, the circle center of the diameter pointing to the circular arc is reversed, a stirrup section 4 is formed, and the bending portions of the two ends of the stirrup section are located on the same plane, as shown in fig. 6. And (3) partially overlapping and welding the stirrup sections 4 in a vertically staggered manner, forming a complete stirrup ring 2 as shown in fig. 5, forming a U-shaped bayonet 3 at the connecting part of two adjacent stirrup sections 4, and matching the width of the U-shaped bayonet 3 with the width of the bamboo chip 1 as shown in fig. 4.

In the embodiment, during specific implementation, according to the length of the stress release hole, a plurality of bamboo chips 1 and a plurality of hoop reinforcement rings 2 are manufactured, the bamboo chips 1 are placed in the U-shaped bayonet 3, and are bound and fixed by binding wires, and finally, a complete bamboo chip cage is formed, as shown in fig. 1.

After the embodiment is implemented, the U-shaped bayonet 3 provides the bamboo chips with the radial and tangential constraint along the hoop rib ring, so that the stability of the whole bamboo chip cage is ensured, and the stress release holes are prevented from collapsing.

Finally, it should be noted that the above embodiments are merely representative examples of the present invention. It is obvious that the utility model is not limited to the above-described embodiments, but that many variations are possible. Any simple modification and modification of the above embodiments in accordance with the technical spirit of the present invention should be considered as falling within the scope of the present invention.
