Description

Assembled skeleton texture and continuous wall

Technical Field

The utility model relates to the technical field, in particular to an assembled framework structure and a continuous wall.

Background

Tunnels are engineering structures buried in the ground and are a form of human use of underground space. The continuous wall is also called underground continuous wall, a trench digging machine is adopted on the ground in foundation engineering, and a long and narrow deep trench is dug along the peripheral axis of the deep digging engineering under the condition of slurry wall protection. After the groove is cleaned, a reinforcement cage is hoisted in the groove, and then underwater concrete is poured by a guide pipe method to form a unit groove section. The construction is carried out section by section, and a continuous reinforced concrete wall is built underground and serves as a water interception, seepage prevention, bearing and water retaining structure. The underground continuous wall is divided into the following filling materials: the concrete wall, reinforced concrete wall, composite wall.

The continuous wall has the following functions: (1) and (4) soil retaining. When the trench of the underground diaphragm wall is excavated, the earth near the ground surface is very unstable and easily collapsed, and the slurry cannot function as a retaining wall, so that the guide wall functions as a retaining wall until the unit trench section is excavated. (2) As a reference for the measurement. The position of the groove is specified, the division of the unit groove section is indicated, and the division is also used as a reference for measuring the elevation, the verticality and the precision of the digging groove. (3) As a support for the weight. The support is not only a support of a grooving mechanical track, but also a supporting point for placing a reinforcement cage, a joint pipe and the like, and sometimes also bears the load of other construction equipment. (4) And storing the slurry. The guide wall can store mud and stabilize the level of the mud in the tank. The slurry level should be kept 20cm below the guide wall surface and 1.0m above the ground water level all the time to stabilize the tank wall. (5) Slurry leakage is prevented; prevent rainwater and other ground water from flowing into the grooves.

The continuous wall has the following advantages: (1) the construction method has the advantages of small vibration, low noise, high construction speed and large construction depth, and is very suitable for constructing deep foundation pit supports and reverse construction in urban dense building groups. (2) The wall body has high rigidity, good integrity, seepage resistance and durability and reliable quality, and when the wall body is used for foundation pit excavation, the foundation settlement or collapse accidents are rarely caused, and water is hardly leaked. (3) The underground continuous wall can be constructed by clinging to the original building and can be used for reverse construction. (4) The occupied area is small, the limited ground and space within the red line of the building can be fully utilized, and the investment benefit is fully exerted. (5) Is suitable for various foundation conditions. The method can adapt to more complex geological conditions, and underground continuous walls can be built on all foundations from weak alluvial strata to medium-hard strata, compact gravel layers and sandy soil layers, various soft rocks and hard rocks and the like. (6) Can be used as a rigid foundation. Underground continuous walls are not used as seepage-proofing, waterproof and deep foundation pit maintenance walls for a long time, and increasingly replace pile foundations, open caisson or caisson foundations with underground continuous walls to bear larger loads. (7) The underground continuous wall is used as a vertical seepage-proofing structure of hydraulic buildings such as earth dams, tailing dams, water gates and the like, and is very safe and economic. The underground continuous wall belongs to an advanced construction method, utilizes the same protective outer wall of an underground space structure as a deep foundation pit support, cancels a construction method of additionally using some underground engineering as a supporting wall, saves materials, reduces the manufacturing cost and has obvious economic benefit.

The underground continuous wall steel bar assembled skeleton structure in the tunnel in the prior art is arranged between the water stopping I-beams on two sides of the underground continuous wall, the I-beams have the water stopping effect, two side faces of a steel reinforcement cage are respectively connected with the water stopping I-beams on two sides of the underground continuous wall, if the I-beams are damaged and lose the water stopping function, the I-beams must be directly replaced, and the steel reinforcement cage connected with the I-beams also needs to be detached, so that manpower and material resources are wasted. And two adjacent assembled skeleton structure of underground continuous wall steel bar assembled skeleton texture in the tunnel among the prior art only form as the connecting plate welding through a steel sheet when connecting, connect unstablely, cause adjacent assembled skeleton structure to loosen easily, destroy the continuous wall wholeness, influence the fender soil of continuous wall, supporting role even.
