Abstract

The utility model relates to a general combined road structural member, comprising a pavement structural member, a drain tank structural member and a middle isolation belt structural member. The pavement structural member, the drain tank structural member and the middle isolation belt structural member are all made from reinforcing steel and concrete in the method of concrete casting. The pavement structural member, the drain tank structural member and the middle isolation belt structural member are matched with each other into an integral road body. Both edges of the pavement structural member which are step-shaped and hollow can be mutually engaged. The drain tank structural member is concave and hollow, wherein, one edge of the drain tank structural member which is step-shaped can be engaged with the pavement member. The middle isolation belt structural member is hollow. One edge of the middle isolation belt structural member which is step-shaped can be engaged with the pavement member. The other edge of the middle isolation belt structural member is L-shaped or arc-shaped. The production of pavement member can be implemented simultaneously in subgrade engineering to reduce the construction period of the engineering. Therefore, quality monitoring is facilitated. Reinforcing steel structure net frames and cylindrical and hollow holes are added into the members in order to increase the durability and the rolling prevention performance of pavement, reduce the consumption quantities of materials, and mitigate the weight of the integral pavement.

Description

The box-like highway member of common group

The utility model belongs to the engineering construction class, exactly is the box-like highway member of common group.

The development of society depends on the construction of highway, and it is the assurance of production environment and living environment, and its construction level of highway network is to weigh an area, one of standard of a national national economy strength.

Highway Construction Project Based, its engineering generally are divided into three parts: subgrade construction (comprise and dig the muck haulage cubic meter of stone, finishing, flattening-out) and pavement engineering (comprising laying of roadway, draining) and road surface ancillary works (comprising illumination, guardrail, graticule).All the time, highway construction project is that preface is constructed respectively successively basically, so its shortcoming is more: after 1. subgrade construction was finished, every section every ground surfacing caused construction speed slower again; 2. because the road surface is directly to construct for cement concrete, is difficult to place the bar construction rack and in cement concrete, forms hollow hole, under the unsteady situation of roadbed, cause the road surface fracture, collapse damage; 3. along the line, the soil structure of highway differs, and highway torsional deformation can occur, sink, break.Relevant conveyance system project (as culvert) situations such as dislocation can occur when dealing with improperly; Maintenance process to highway has just caused bigger difficulty, can only will carry out making again or filled bitumen on the road surface after the cleaning of former road surface; 4. road engineering material can not repeat secondary and use.

The utility model is exactly to provide combined type highway member for the shortcoming that overcomes above-mentioned technology, and it can be widely used in highway and other municipal engineering construction.

The box-like highway member of common group is characterized in that comprising road surface member, rhone member and intermediate isolating band member, and they all are to be formed by reinforcing bar, concrete casting, and they cooperatively interact becomes a highway integral body; Member two edges, road surface are stepped ramp type, interlock mutually, hollow; The rhone member is " recessed " type, hollow, wherein an edge is stepped ramp type, can with road surface member interlock; Intermediate isolating band member, hollow, a wherein edge of member is stepped ramp type, can with road surface member interlock, another edge is " L " type or camber.

The utility model adopts the pre-member mode, in the Con struction in Roadbed process, can implement the production of road surface member simultaneously, reduces the engineering construction phase widely; The highway pavement member is easy to carry out quality monitoring in process of production, in pre-member, add bar construction rack and cylindrical hollow hole, increase the road surface durability, rolling resistance, reduce material use amount, alleviate the weight on whole road surface, more convenient road surface member is installed; During distortion situations such as highway occurs in use twisting, sink, pre-member is sling, can implement the roadbed repair.

Fig. 2 is a rhone member schematic diagram of the present utility model;

Fig. 3 is an intermediate isolating band member schematic diagram of the present utility model;

Fig. 4 is the schematic diagram that the utility model is combined into highway.

Below in conjunction with description of drawings.

As shown in the figure, the 1st, the hole that hollow forms, the 2nd, the step at edge.

The box-like highway member of common group comprises road surface member, rhone member and intermediate isolating band member, and they all are to be formed by reinforcing bar, concrete casting, and they cooperatively interact becomes a highway integral body; Member two edges, road surface are stepped ramp type, interlock mutually, hollow; The rhone member is " recessed " type, hollow, wherein an edge is stepped ramp type, can with road surface member interlock; Intermediate isolating band member, hollow, a wherein edge of member is stepped ramp type, can with road surface member interlock, another edge is " L " type or camber.

This pre-member is generally rectangle, and hexagon, square etc. are designed the member of certain specification by the length and width of highway, and for ease of construction, general member specification is 6-20M ², weight can be controlled in general lifting facility convenient construction and is degree, member can about use.
