The invention relates to a horizontal self-locking assemble wallboard and a construction method of a horizontal self-locking assemble wallboard embedded into a construction wall body. The horizontal self-locking assemble wallboard is prepared by compounding a glass fiber grid cloth surface enhanced flow-state micropore lightweight concrete basal body and a rock wool heat preservation core plate, wherein the micropore lightweight concrete slurry and the rock wool heat preservation core plate are integrally subjected to gapless tight compounding and one-time pouring moulding; convex groove tenons and concave groove tenons are arranged at the left side, the right side, the upper part and the bottom part of the basal body; during wall formation, the wallboard is combined with each light steel keel having the same size as that of the cross section of each concave-convex tenon, and the light steel keels are placed in the concave-convex tenons of the assemble wallboard so as to form a lightweight wall body embedded with the light steel keels. By utilizing the structural characteristics, the technical problem that steel-structured construction is quickly assembled and constructed to form the wall body is solved, and the wallboard has the characteristics of light weight, high strength, seismic resistance, heat insulation and heat preservation. The steel structure systems can be used for constructing the wall body project having multifunctional requirements on relatively high seismic resistance, energy conservation, fireproofing and the like.

The self-decoration reactive powder concrete is prepared from 16%-30% of cement, 10%-35% of admixture, 1%-5% of fibers, 23%-44% of fine aggregates, 0.5%-5% of high-efficiency water reducing agent, 0-0.5% of colorant, 0-5% of titanium dioxide and 9%-18% of water, the self-decoration reactive powder concrete serves as a construction material and a decorative material, the compressive strength is larger than or equal to 100 Mpa, the flexural strength is larger than or equal to 15 Mpa, the fluidity ranges from 300 mm to 350 mm, pouring is conducted to make a decorative hollow-out hanging plate through a hollow-out mold, reinforcements are not needed, and a light and attractive hanging plate can be made. Compared with an ordinary decorative hollow-out hanging plate, the hanging plate is free of reinforcements, small in thickness, light in size, light in weight, convenient to transport and install, rapid and efficient in construction, high in strength, good in bearing capacity, resistant to impact, good in waterproof and anti-cracking property, good in weather resistance, good in decorative effect and capable of being widely applied to fabricated building construction.

The invention discloses a construction method of an underground shaped pool. The construction method comprises the steps of manufacturing of a steel plate internal mould, foundation marking and location, earth excavation, pit bottom pretreatment, concrete pouring, installation and location of the steel plate internal mould, backfilling, concrete pouring, wire-tie and concrete pouring. The construction method of the underground shaped pool has the advantages of easy operation, high practicability, and fast and efficient construction, the underground construction time can be reduced; the influence of earthwork caving and ponding in the underground construction on production and life is relieved effectively, and the whole engineering construction from the manufacturing of the steel plate internal mould to completion of the concrete pouring needs 2-3 days only, and the construction period is shortened by 12-13 days compared with the previous methods; the construction period is shortened, and the working efficiency is improved; the construction cost is saved.

The invention discloses a full-sleeve thin-wall filling pile construction method and a movable internal mould. The construction method increases the capability for penetrating the foundation soil by the single layer sleeve by a large scale with the large exciting force and high-frequency vibrating hammer. A majority of groundwork soil layers except the strong decayed rock can be penetrated. The single layer sleeve which is longer than 20 meters and has diameter for 0.8-2.0 meters is one-time sunk into the foundation soil. The earth can be fetched by carrying an earth-fetching pipe by a high-frequency hammer or fetched artificially. When the designing request is satisfied, a movable internal mold and a reinforcement cage are taken into and the concrete is poured. The single layer sleeve isthen vibration-drawn out. When the concrete is finally solidified, the movable internal mold is detached and is filled again thereby forming a thin-wall filling pile. The technique increases the construction efficiency for a large scale and avoids the influence of the squeezed earth to the surrounding building, roadway and pipeline and the pollution to the surrounding environment. The vibration and drawing of the pipe can greatly increase the quality of the concrete at the pile shaft. The using of the movable internal mold saves considerable amount of concrete to obtain a maximum structure effect with a least material consumption.

The invention relates to a retaining wall using waste concrete sleepers and its construction method. According to the required height of the retaining wall, if the required height is not greater than the threshold, the whole waste and old sleepers are inserted into the soil body longitudinally and laid along the slope to form a longitudinal retaining wall. The height of the longitudinal retaining wall above the surface of the soil meets the height required by the retaining wall; if the required height is greater than the threshold, it is cut into sleeper blocks, and the sleeper blocks are used to build the mortar foundation and the mortar retaining wall, and the mortar retaining The height of the wall meets the required height. The construction of the retaining wall of the present invention adopts waste concrete sleepers, reduces the use of chipping stones, block stones or concrete materials, achieves the purposes of waste utilization, green energy saving, and reduces project cost. The construction of the retaining wall constructed by the waste concrete sleeper of the present invention is more efficient and fast, and compared with the cast-in-situ concrete retaining wall, the construction time is greatly reduced. Retaining walls of different structures are used according to different needs, which ensures that the strength of the retaining walls meets the requirements and improves the utilization rate of waste concrete sleepers.
