The invention discloses a construction method of a permanent rigid waterproof layer. The method comprises the steps that firstly, the surface of a braced wall or cushion is subjected to waterproof andleveling treatment; then, a spraying machine is used for spraying plain mortar to the braced wall or cushion to form a first plain mortar layer of 2 to 5 mm, a second cement mortar layer of 4 to 8 mm, a third plain mortar layer of 2 to 5 mm, a fourth cement mortar layer of 4 to 8 mm and a fifth plain mortar layer of 2 to 5 mm, and a rigid waterproof layer is formed; a structure wall is constructed in the rigid waterproof layer of the braced wall, the braced wall and the structure wall are integrated, foundation bearing force and anti-buoyancy can be greatly improved, a certain constraint effect on foundation soil rebound, uplift and subsidence can be achieved, the rigid waterproof layer, the braced retaining wall and the structure wall in a foundation pit are made of the same material, have the same strength and durability and are easily bonded together, in foundation construction process, precipitation and pollution discharge are not needed, fertilizer groove backfill is not needed,the construction speed is high, the quality is good, the cost is low, and the method is ideal green construction.

The invention relates to the technical field of building construction, in particular to a waterproof construction method of a HCMW construction method laminated wall. The waterproof construction method of the HCMW construction method laminated wall comprises the following steps of A, HCMW construction method supporting pile wall construction, B, excavation of a foundation pit, C, leveling of the wall with waterproof mortar, D, base treatment agent brushing, E, coil laying; F, waterproof mortar spraying; G, steel bar binding; H, formwork supporting; and I, concrete pouring. A HCMW constructionmethod laminated wall waterproof system combines rigidity and flexibility and has multiple waterproofing and good waterproofing effect; a novel impermeable waterproof material is added in the concrete, the concrete structure has good waterproof performance; and two layers of anti-cracking waterproof mortar protection coils are installed to prolong the service life of the waterproof system and thewaterproof effect of the waterproof system.

The invention discloses a composite structure with bracing soldier piles and a basement exterior wall overlapped and a construction process of the composite structure. The bracing soldier piles are arranged in a column manner at equal intervals and are closely attached to the outer side of the basement exterior wall, after concrete is poured into the clearances between embedded horizontal reinforcement in pile bodies of the bracing soldier piles and the soldier piles, a continuous overall pile wall is formed, and a shear force groove is formed in the pile wall. After the surface of the pile wall is scabbled and cleaned up, the bracing soldier piles and the basement exterior wall are connected to form overlapped connection through the shear force groove in the pile wall and reinforcement connectors in the bracing soldier piles, and thus the composite structure for resisting external water and soil pressure together is formed. According to the composite structure, the horizontal stiffness and bending resistance of the bracing soldier piles can be fully utilized, the bracing soldier piles and the basement exterior wall are combined, so that a temporary bracing structure becomes one part of a permanent underground main structure, then stress of the basement exterior wall is relieved, the thickness of the basement exterior wall is reduced, the usable area of a basement is increased,and social resources are saved.

The invention discloses an underground structure outer wall superposed wall adopting the HCMW construction method. The underground structure outer wall superposed wall adopting the HCMW construction method comprises a cement-soil mixed pile wall, a levelling course and an underground structure outer wall. The cement-soil mixed pile wall comprises multiple cement-soil mixed piles which are continuously and mutually engaged. Reinforced concrete precast piles are inserted in the multiple cement-soil mixed piles at intervals or continuously. The levelling course is arranged on the inner wall of the cement-soil mixed pile wall. The underground structural outer wall is arranged on the inner wall of the levelling course and comprises reinforcing steel bars and concrete mixed with a waterproof compacting agent. The cement-soil mixed pile wall and the underground structural outer wall constitute an integrated force bearing component through a connection structure. The invention further provides a construction method of the underground structure outer wall superposed wall adopting the HCMW construction method. In this way, the underground structure outer wall superposed wall adopting the HCMW construction method is simple and reasonable in structure, a foundation pit is omitted, a series of defects of the foundation pit are avoided, the waterproof performance is improved, a support wall and a underground structure wall are connected into the force bearing integrated body, the strength is improved, the procedure is simplified, construction is convenient and the construction period is shortened.
