The invention relates to a support structure for a stand column and dual cantilever beams in any combination and a use method of the support structure. The support structure comprises a steel tubular column and dual cantilever beams, wherein a plurality of layers of force bearing rings are arranged on the outer side of the steel tubular column at intervals, a plurality of first reinforcing plates are arranged between the lower side surfaces of the force bearing rings and the outer wall surface of the steel tubular column; the dual cantilever beams include a left half cantilever beam and a right half cantilever beam which are mutually symmetric, arc grooves matched with the outer side of the steel tubular column are arranged in the spliced surfaces of the left half cantilever beam and the right half cantilever beam, the arc grooves are internally provided with force transmission ring sections matched with the force bearing rings, a plurality of second reinforcing plates are arranged between the upper side surfaces of the force transmission ring sections and the inner walls of the arc grooves, the left half cantilever beam and the right half cantilever beam are provided with arc straps for tightly banding the left half cantilever beam and the right half cantilever beam on the steel tubular column, connection end plates are vertically arranged at the two ends of the arc straps, and each connection end plate is provided with a first connection hole for allowing a first connection bolt to pass through. The support structure is large in born force and can be used repeatedly and flexibly.

The invention discloses a method which uses steel slag, mineral slag or electric power plant slag as the materials of a self-hydrating activation type pavement basic layer to activate the potential hydrating activation of the mineral slag or the pozzuolana activation of the electric power plant slag by the corresponding interlocking effect of each waste and the self-hydrating activation of the steel slag to form hydrated C-S-H, C-S-A-H, or C-S-A-F-H, ettringite, and calvital hydration product, form the initial strength of the pavement basic layer and ensure the continuous increasing of the later strength; counted by weight portions, the mixture ratio of each material is as follows: 40 to 65 portions of steel slag, as well as 35 to 60 portions of mineral slag and / or electric power plant slag. The pavement basic layer is a non-cement basic layer with excellent performance, and the preparation method thereof is as follows: the materials after being mixed are transported to a construction field, paved, rolled, and maintained by moisture retention to a regulated age. The invention uses industrial wastes, can save land and resources and reduce the cost, is beneficial to protecting environment, is simple to be constructed, and is suitable for building the basic layers and the foundation layers of common roads and advanced roads.

The invention discloses a steel bar anchor connection structure and connection method of prefabricated assembled concrete components. The steel bar anchor connection structure comprises a first prefabricated concrete component and a second prefabricated concrete component located above the first prefabricated concrete component. The bottom of the component is provided with a steel bar anchoring reserved hole for anchoring the first steel bar embedded in the first prefabricated concrete member; a grouting structure is provided in the cavity between the steel bar anchoring reserved hole and the first steel bar; the steel bar anchoring reserved The hole is located outside the lower part of the second steel bar arranged in the second prefabricated concrete member, and a plurality of grooves are arranged on the inner side wall of the reserved hole for anchoring the steel bar; the method for anchoring and connecting the steel bar includes the steps: 1. Prefabrication of the second prefabricated concrete member; 2. 1. Hoisting of the second precast concrete component and insertion of the first steel bar; 3. Grouting; 4. Maintenance. The invention is reasonable in design, convenient in realization and good in use effect, can simply and quickly complete the steel bar connection process and is reliable in connection.

The invention relates to a compound waterproof system and a construction technology thereof. The compound waterproof system comprises an inner base layer, a compound waterproof layer and an outside protective layer, wherein the inner base layer is formed by a non-solidifying waterproof gluing which has double features that the non-solidifying waterproof gluing is in a solid state after contacting with air at normal temperature and a flexible glue bonding state can be kept under sealed anaerobic conditions, the compound waterproof layer is formed by an outer strengthening layer formed by a high-performance synthetic rubber asphalt waterproof roll material composed of an upper covering layer, a lower covering layer and a middle modified asphalt gluing layer, and the outside protective layer is composed of polyethylene film or non-woven fabrics and fine stone concrete and steel bar mesh. The non-solidifying waterproof gluing is directly coated on a base surface, the waterproof roll material is covered and glued on the outer surface of the inner base layer, and the edge contacting parts and the surrounding edge parts of the waterproof roll material are all coated and sealed by the non-solidifying waterproof gluing so that the whole inner of the compound waterproof layer is in a sealed state. Adopting the setup of clod construction, the compound waterproof system has the advantages of reasonable components, scientific structure and reliable construction technology, reaches active technique effects of long-time no leakage for buildings, and has very strong practical applicability and commendable market application prospect.
