2nd step: the compacting element soil that the leveling first step obtains, builds concrete cushion above the plain soil of compacting;
3rd step: build rubble-mound foundation layer on concrete cushion by laying bricks or stones, selects large and smooth rubble to use masonry of cement mortar to form;
4th step: on the rubble-mound foundation layer that the 3rd step obtains, releases sideline bottom body of wall, successively builds rubble layer, and the center line according to basis releases wall body inside and outside sideline, and hanging wire divides skin sleeping block, and every skin is to about 300mm; First floor adopts the slurry that completely lays cement, and selects large and plain rubble, first builds corner, junction, then build by laying bricks or stones to centre; Collocation size rubble, large face keeps flat down, expose flush face, angle inwardly, between middle rubble, cement mortar is first clogged in larger space, after use the embedding reality of rubble, back side surface rubble gap use thinner stone level up and use cement mortar point glue, thinner stone sticks into as an adhesive hair stone via cement mortar point; And successively up build by laying bricks or stones successively, build back side by laying bricks or stones and build by laying bricks or stones to water surface stepped cross; In building process, every 0.7m
2select the rubble of a block length bar to build as drawknot barnacle, keep drawknot stone to be staggeredly located, and in same intracutaneous distance≤2m; Often block 3 layers is once levelling, and point fills up cement mortar in sticky gap;
5th step: when building to top, uses cement mortar comprehensively levelling and bears down on one with smooth concrete, obtaining body of wall;
6th step: have gutter in the rubble-mound foundation layer arranged outside of back side, gutter is cast-in-place grooved concrete structure, and plaster by 1:2.5 cement mortar inside gutter and find out the gradient;
7th step: the building wall strength of cement mortar after the 4th step to be detected, after pressure testing reaches 70% of design strength, carries out back backfill; The rubble lamellar spacing on back side surface is not that residual soil and the mixed soil paste that remains of water of the position humidity of an adhesive hair stone masonry of cement mortar fills up;
8th step: thin snow 10000 years grass and stonecrop spacing 200 millimeters are planted in remaining in soil paste seam in quincunx, water with sprayer, protect tide one week, if poor growth, can spray and water nutrient solution, vegetation just can cover 80% of whole surface of wall in 1 year.
10. the construction method of the ecological retaining wall of gravity point adhesive hair stone plant filleting according to claim 9, is characterized in that, in described 4th step, when body of wall thick≤40cm time, select the length of the rubble as drawknot stone to equal wall thickness; Or, as the thick > 40cm of body of wall, select the inside and outside overlap joint of two blocks of rubbles, lap length >=15cm, and wherein one block of rubble length >=wall thickness 2/3.
