Abstract

A grouting structure filled with a soluble crystal and a construction method. The structure comprises a permeable section (21) and a grouting section (22). A water stop member (23) is provided between the permeable section (21) and the grouting section (22). A permeable pipe (1) is provided in the permeable section (21). The permeable pipe (1) is filled with a solid soluble crystal (3). A water inlet of a water drainage pipe (4) is provided in the permeable section (21). The elevation of the water inlet of the water drainage pipe (4) is higher than the elevation of a water outlet of the water drainage pipe (4). This structure increases grouting pressure, reduces cracks in the grouting section (22), improves a sealing effect, and therefore improves a negative pressure effect of the permeable section (21). During grouting, the water stop member (23) is effectively supported, thereby preventing slurry from entering the permeable section (21) and interfering with formation of a negative pressure environment, thus preventing blockage of the permeable pipe (1), and preventing a large displacement of the water stop member (23) caused by pressing. The present invention ensures that water can be continuously drained in a deep layer of a slope, and contributes to resolving the issue of water drainage and treatment of a large-scale landslide.

The ballasted track temporary line (20) consists of a ballasted track bed (21) and a railroad tie (22). A transition section (L1) is provided between the main line ballastless track (10) and the ballasted track temporary line (20) to use as the temporary line transition connection foundation. A main body of the transition section (L1) is a reinforced concrete widened track bed (30) poured on the outer side of an existing ballastless track bed (12). A certain length in front of the transition section (L1) and the main line ballastless track (10) is a track surface elevation lifting section (L2). Assembling track bearing tables (40) are fixedly provided on top surfaces of the existing ballastless track bed (12) and the reinforced concrete widened track bed (30) in the track surface elevation lifting section (L2). By means of the assembling track bearing tables (40), a temporary line steel track (23) is locked, and the geometry of the track surface is arranged for completing the temporary line connection. The connection structure shortens the construction time of the connection foundation to the greatest extent, and lays a solid foundation for connection to the main line ballastless track (10) in one maintenance window period after the underlying foundation defects of stations are thoroughly treated.

Abstract

Disclosed are a composite lightweight pile structure, a manufacturing method, a construction method and a pile connecting method. The composite lightweight pile structure comprises lightweight soil and a composite reinforcement cage. The composite reinforcement cage comprises vertical geogrids arranged at intervals in the circumferential direction and annular geogrids arranged at intervals in the vertical direction. The lightweight soil material is low in density and high in compression resistance, and the composite reinforcement cage utilizes the tensile capacity of the geogrids to have the effect of a stirrup under the action of a pile top load so that a pile body has higher compression-resistance capacity, and pile collapse or pile breaking is avoided. Meanwhile, the composite reinforcement cage can prevent a composite lightweight pile from cracking, and the structure reduces foundation in-situ effective stress by replacing foundation rock soil. The cage can be used for balancing an overlying load so as to reduce additional stress from the overlying load in a foundation. The structure is high in compression-resistance strength, and the foundation can be reinforced. The bearing capacity of the foundation is improved, and the overlying load can, by means of the structure, be transmitted to a rock-soil stratum which is well laid. The additional stress of an existing building is prevented from increasing, and the purpose of controlling foundation deformation is achieved.

Abstract

Disclosed is a method for improving the anti-sliding and anti-overturning safety of an existing balanced-weight retaining wall. Part of the bearing capacity still reserved by an existing balanced-weight retaining wall is fully taken into consideration, and after anchoring piles are used in front of the existing balanced-weight retaining wall for reinforcement, the resistance of the existing retaining wall is improved, such that the anti-sliding and anti-overturning safety of the structure is improved; and the size of the anchoring piles is designed according to the stress of the existing balanced-weight retaining wall and the stress of the newly built anchoring pile. Compared with the prior art, the load shared by the anchoring piles is reduced, the size of the anchoring piles is optimized, and therefore on the premise that safety is guaranteed, project investment is reduced, and the economical efficiency is improved. Moreover, the anchoring piles and the balanced-weight retaining wall are anchored together by means of steel bars to form a whole, and the structural integrity and the anti-seismic performance are good.
