CN-122013810-A - Arch cloth stake antiskid protective structure retaining wall

Abstract

The invention relates to the field of slope anti-slip protection engineering of industrial and civil building sites, highways, municipal roads, city squares and airports, in particular to an arch-shaped pile-distribution anti-slip protection structure retaining wall which is arranged in a rock-soil foundation and comprises top connecting crown beams, middle cast-in-place piles and jet grouting piles. The middle filling pile and the jet grouting pile are connected with the top to form an annular shape on the plane of the crown beam to form an arch-shaped integral stable structure, so that the stability effects of slip resistance, overturning resistance, bending resistance, shearing resistance and the like are achieved, and the filling pile and the jet grouting pile form an annular curtain to guide groundwater to be discharged from two sides, so that the building to be protected is prevented from being directly scoured.

The middle cast-in-place pile (1), the jet grouting pile (3) between the cast-in-place piles and the plane of the crown beam (2) connected with the top are annular, so that an arched integral stable structure is formed, the integral stability effects of slip resistance, overturning resistance, bending resistance, shearing resistance and the like are achieved, and the jet grouting pile (3) between the middle cast-in-place pile (1) and the cast-in-place pile forms an annular curtain to guide groundwater to be discharged from two sides, so that the building (4) to be protected is prevented from being directly scoured.
2. 2. The retaining wall with the arch-shaped pile-laying anti-slip protective structure according to claim 1, wherein the middle cast-in-place pile (1) is anchored in a weathered bedrock (7) in the bottom of the pile not less than 5m according to geological conditions.
3. 3. The retaining wall with the arch-shaped pile-distributing anti-slip protective structure according to claim 1, wherein the annular curtain is formed by the jet grouting piles (3) between the middle cast-in-place piles (1) and the cast-in-place piles, and the air-immersed bedrock (7) entering the bottom is not less than 1m.
4. 4. The retaining wall with the arch-shaped pile-distribution anti-slip protection structure according to claim 1 or 2 is characterized in that the length of the annular curtain formed by the jet grouting piles (3) between the middle cast-in-place piles (1) and the cast-in-place piles covers a building (4) to be protected, and the retaining wall really plays a role in protecting water diversion decompression and the like.

Description

Arch cloth stake antiskid protective structure retaining wall Technical Field The invention relates to the field of slope anti-skid protection engineering of highways, municipal roads, urban squares, industrial factories, airports and the like, in particular to an arch-shaped pile-distribution anti-skid protection structure retaining wall. Background With the development of urban and rural construction in China, the house which has generated displacement on the existing deep soil layer landslide body is often required to be protected, collapse damage is avoided, and due to the limitation of factors such as construction funds, land-feature range, surrounding environment and the like, the traditional mode often needs to adopt a slope protection mode such as single-row supporting piles and anchor cables or double-row pile supporting piles. Deep soil layer, long anchor cable, poor effect, high cost of double row piles and narrow field. The retaining wall with the traditional structure is difficult to meet the requirements of safety, economy, construction feasibility and the like, and a combined structure retaining wall which is safe, economical and convenient to construct is urgently needed. Disclosure of Invention Aiming at the problems of the background technology, the invention aims to provide the retaining wall with the arch-shaped pile-distribution anti-slip protective structure. An arch cloth stake antiskid guard structure retaining wall, integrated configuration retaining wall set up in the ground, including top connection crown beam, middle part bored concrete pile, the jet grouting pile between the bored concrete pile. The rotary jet grouting pile and the cast-in-place pile form an annular curtain to guide underground water to be discharged from two sides, so that the direct flushing of buildings to be protected is avoided. Further defined, the middle cast-in-place pile is anchored in the bottom by weathered bedrock not less than 5m according to geological conditions. Further limiting, the jet grouting piles between the middle cast-in-place piles form an annular curtain, and the air-changed bedrock in the bottom is not smaller than 1m. Further limited, the length of the jet grouting pile curtain between the middle cast-in-place piles covers the building to be protected, and the protection effects of retaining, water diversion, pressure reduction and the like are truly achieved. The invention has the following beneficial effects: 1. According to the invention, through the structural optimization design, the ground vertical and horizontal loads are directly transmitted to the lower bedrock stable stratum through the middle filling pile and crown beam combined structure. 2. The jet grouting piles among the middle cast-in-place piles and the cast-in-place piles form an integral stable structure with the crown beam connected with the top and the weathering bedrock in the bottom, and the integral stability effects of slip resistance, overturning resistance, bending resistance, shearing resistance and the like are achieved. 3. The rotary jet grouting pile between the middle cast-in-place pile and the top are annular on the plane of the crown beam connected to form an arch structure, so that the anti-slip, anti-overturning, bending and shearing capabilities of the retaining wall are improved. Drawings The invention can be further illustrated by means of non-limiting examples given in the accompanying drawings; FIG. 1 is a schematic view of an embodiment 1 of a retaining wall with an arch pile-laying anti-slip protective structure according to the present invention; FIG. 2 is a front view of an embodiment 1 of a retaining wall with an arch-shaped pile-laying anti-slip protective structure according to the present invention; fig. 3 is a side view showing the structure of an arch-shaped pile-laying anti-slip protective structure retaining wall according to embodiment 1 of the present invention.
