Abstract

The utility model provides a retaining wall with anchor plates, composed of a plurality of unit components comprising face plates, draw rods and anchor plates. The utility model is characterized in that each unit component forms an umbrella shape, each unit component has one draw rod whose both ends are respectively connected with one face plate and one anchor plates. The retaining wall has low cost, low material consumption, light member and manual construction and installation.

Description

Anchored plate retaining wall

The utility model relates to a kind of civil works retaining wall, particularly be a kind of novel anchored plate retaining wall.

Be anchored to the retaining wall that bankets behind the wall and quietly rise at the seventies in weak soil, it is than generally low approximately by 30% with traditional gravity retaining wall cost, and the suitable for mechanization construction can be saved artificial and accelerating construction progress.Build bulkhead wall Chang Buneng and obtain the better economic effect but 1. have inconvenient traffic for the two sides, river course; 2. it is big that the steel tie rod of imbedding is generally the galvanizing steel of anti-corrosion or stainless steel band and expense, anti-cost not as good as traditional gravity retaining wall of gathering materials on the spot is low in unfavorable area like this, the form that this class retaining wall is popular all makes the assembling of a plurality of unit blocks usually, generally has two kinds: 1. reinforced earth retaining wall: add root galvanizing steel (band) and make pull bar and make upright panel firm by means of the frictional force of reinforcing bar and soil after its unit block is panel.This retaining wall reinforcing bar is more and long, expends greatlyyer, will strengthen the excavation and filling earth volume on riverbank in some cases; 2. anchored plate retaining wall, unit block are that a panel, four pull bars and a form anchor are formed.This type shortens steel bar rod and has reduced drawknot length.Be provided with fritter concrete grappling plate to increase the anti-power of dialling at the pull bar end.But ram the pressure construction because of there being the grappling baffle plate to be unfavorable for banketing, in compacting process, bring the uncertainty of reinforcing bar pulling force, earth filling tamping during the little obstruction of clearance between tiebars is constructed in addition, make pull bar become the beam of two ends drawknot in the natural compacting process that bankets, the imponderable weight that load bankets is unfavorable to structural safety.

In view of above reason, the purpose of this utility model is in order to overcome above deficiency, provide that a kind of cost is low, material expend few, the anchored plate retaining wall of easy construction.

The purpose of this utility model is achieved in that the utility model retaining wall is made up of a plurality of unit blocks that contain panel, pull bar, form anchor, the umbrella shape that is shaped as that it is characterized in that each unit block, pull bar in each unit block is one, and the two ends of pull bar are connected (referring to Fig. 1, Fig. 2) with a panel with a form anchor respectively.

One end of above-mentioned pull bar is connected on the center of panel (referring to Fig. 2).

The utility model particularly only is provided with a pull bar rather than four pull bars at each panel in the center, both reduce the pull bar closeness greatly and saved material, widened the not overslaugh of space of the banketing work of banketing again greatly, easy to operate, make artificial ramming also can carry out smoothly.

Compare with existing anchored plate retaining wall, the utlity model has following advantage:

1), cost is low, can save 60% by general retaining wall, and the duration is short, but the reduction of erection time 40%.Through test, its every meter long consumptive material on 5 meters high walling works, cement 240kg except that locality, sand-pebble, steel 58kg is because the basis reduces the excavation and filling earthwork and saves 40% approximately; Because body of wall can allow that moderate finite deformation and basis carrying are lighter, and compact simplified basis can be set, and can exempt draining and enclose ancillary workss such as low bank between fields; Construction can be saved mechanical stage student contributions pooled to pay for class activities and scaffold and take entirely by artificial installation;

2) prove through structured testing and the test of time: rational in infrastructure, safe and reliable, the umbrella shape unit block is stable and rational, does not find any deformation of wall;

3), easy construction, member is light, and maximum construction weight is below 300 kilograms, and no cast in situs partly with pacifying with filling out, need not be set up bracing frame and scaffold, and it is quick again to make construction save.

The utility model is specially adapted to the river that the two sides, region of no relief are sand loam soil city or country, and the bulkhead wall height is below 6m.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model anchored plate retaining wall structural representation.

Fig. 2 is a umbrella shape unit block structural representation.

Referring to Fig. 1, Fig. 2, anchored plate retaining wall 1 is spliced by a plurality of umbrella shape unit blocks 2, the panel 3 that adopts prefabricated low arrangement of reinforcement steel concrete ribbed plate to make is arranged in each umbrella shape unit block, prefabricated concrete grappling plate 4, pull bar 5 one ends that adopt the plain bars (also available galvanizing steel) add antirust processing to make are connected on the form anchor 4 and the other end is connected on the center of panel 3.

Claims

1, anchored plate retaining wall, form by a plurality of unit blocks that contain panel, pull bar, form anchor, the umbrella shape that is shaped as that it is characterized in that each unit block, the pull bar in each unit block are one, and the two ends of pull bar are connected with a form anchor with a panel respectively.

2, anchored plate retaining wall according to claim 1 is characterized in that an end of pull bar is connected on the center of panel.
