Description

An Underground Diaphragm Wall Structure That Can Be Chiseled Quickly

technical field

The utility model relates to the field of building construction structures, in particular to an underground continuous wall structure that can be chiseled out quickly.

Background technique

At present, in the process of chiseling the head of the diaphragm wall of the enclosure structure, the traditional construction technology adopts manual chiseling with jackhammers. During the chiseling process, the noise and dust pollution are serious, causing great harm to the workers and causing serious damage to the surrounding environment. Great impact, and the power consumption of the wind gun machine is large, the construction efficiency is low, and the whole process is cumbersome, labor-intensive, and time-consuming. Especially in the bustling city, it is easy to cause complaints from citizens, resulting in bad social impact, and the cost is high.

Utility model content

In order to solve the above problems, the utility model provides an underground diaphragm wall structure that can be quickly chiseled away, which can improve construction efficiency, reduce construction cost, and reduce environmental pollution.

The technical scheme that the utility model solves its technical problem adopts is:

An underground diaphragm wall structure that can be quickly chiseled out includes a plurality of expansion holes arranged on the diaphragm wall body. Each expansion hole is located between two rows of main ribs on the diaphragm wall body. Silent expansion agents are filled in each expansion hole.

As a further improvement of the technical solution of the utility model, at least two rows of expansion holes are arranged between the two rows of main ribs, and each expansion hole is arranged side by side.

Further as an improvement of the technical solution of the utility model, each expansion hole is spaced apart from each main rib, the hole spacing between two adjacent expansion holes is 200 mm, and the hole diameter of each expansion hole is 40 cm.

As a further improvement of the technical solution of the utility model, the silent expansion agent can be adjusted into a flowable slurry after being mixed with water, and the flowable slurry can generate radial compressive stress and circumferential tensile stress on the hole wall after crystallization.

Beneficial effects of the utility model: the underground diaphragm wall structure that can be chiseled quickly is provided with a number of expansion holes along the diaphragm body, and the expansion holes are filled with a silent expansion agent. Mixing produces stress on the wall of the expansion hole, thereby creating cracks on the diaphragm wall, which facilitates the rapid removal of the diaphragm wall, improves the construction efficiency of the diaphragm wall removal, reduces the dust generated during construction, and reduces environmental pollution.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is a top view of the overall structure of the utility model embodiment;

Fig. 2 is a front view of the overall structure of the embodiment of the utility model.

Detailed ways

Referring to Fig. 1 and Fig. 2, the utility model is an underground diaphragm wall structure that can be quickly chiseled out, including a plurality of expansion holes 2 arranged on the diaphragm wall body 1, and each expansion hole 2 is located in two rows on the diaphragm wall body 1 There are 11 main ribs, and each expansion hole 2 is filled with a silent expansion agent.

This fast chiseling underground diaphragm wall structure is provided with a number of expansion holes 2 along the diaphragm wall body 1, and the expansion holes 2 are filled with a silent expansion agent. The hole wall of 2 produces stress, thereby producing cracks on the diaphragm wall, which is convenient for quickly removing the diaphragm wall, is conducive to improving the construction efficiency of diaphragm wall removal, and reduces the dust generated during construction and reduces environmental pollution.

As a preferred embodiment of the present invention, at least two rows of expansion holes 2 are arranged between two rows of main ribs 11 , and each expansion hole 2 is arranged side by side.

As a preferred embodiment of the present invention, each expansion hole 2 is spaced apart from each main rib 11, the hole spacing between two adjacent expansion holes 2 is 200 mm, and the hole diameter of each expansion hole 2 is 40 cm.

As a preferred embodiment of the present invention, the silent expansion agent can be adjusted into a flowable slurry after being mixed with water, and the flowable slurry can generate radial compressive stress and hoop tensile stress on the hole wall after crystallization.

Two rows of expansion holes are arranged in the middle of the two rows of main reinforcement of the underground diaphragm wall, filled with silent expansion agent, the hole positions of the expansion holes 2 are staggered from the main reinforcement of the underground diaphragm wall, and the hole spacing of the expansion hole 2 is the same as that of the main reinforcement.

The expansion hole 2 is drilled with a portable rock drill, and the drilling depth reaches the elevation of the bottom of the crown beam. When the underground diaphragm wall is chiseled, the expansion agent in the expansion hole 2 is mixed with water to fully react, and the effect of cracking the top of the underground diaphragm wall is remarkable, and the manual jack can be used to chisel it out quickly, achieving fast, efficient and environmentally friendly construction.

The fast and environment-friendly excavation construction of the wall head is carried out through the underground diaphragm wall structure, which improves the construction efficiency, saves energy, accelerates the construction progress, and is beneficial to generate good economic benefits.

At the same time, it reduces the noise and dust pollution in the process of chiseling the top of the underground diaphragm wall, ensures the health of construction workers, and avoids complaints from surrounding citizens. During the construction process, new technologies and processes were adopted to ensure the harmony and unity of project quality, progress and cost, which won wide acclaim from the regulatory authorities and owners, and achieved good social benefits.

Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art can also make equivalent modifications or replacements without violating the spirit of the present utility model. These equivalent modifications or replacements are all included in the claims of this application. within the limited range.
