Abstract
The invention discloses the construction method that a kind of unstability reinforced earth bulkhead reinforces maintenance, comprise the following steps：Punched at existing reinforced earth bulkhead baffle plate plate angle；Arrangement is welded with the cage bar of bracket in hole；Cement mortar is injected in the hole for arrange cage bar；After cement mortar is pre-hardening, second pulp feeding；Sealing off and covering anchorage device is installed to cage bar exposed parts.Present invention reduces difficulty of construction, project progress is accelerated, the time needed for reducing leading, influence of the construction to existing traffic noise prediction can be efficiently reduced.
Description
Technical field
The present invention relates to a kind of construction method, in particular, it is related to a kind of unstability reinforced earth bulkhead to reinforce maintenance
Construction method.
Background technology
Reinforced earth bulkhead as a kind of common barricade supporting and retaining system form, due to the advantage, quilt such as its low cost, supporting and retaining system effect be good
It is widely used in the middle of road project.But by the development of the nearly 30 years Road Transportations of China, that builds in early days adds
Muscle soil barricade rib tape ageing failure problem is increasingly highlighted, or even causes the destabilization problems such as reinforced earth bulkhead slides, baffle plate comes off.Cause
To facing, unstability is threatened this needs or the reinforced earth bulkhead of unstability has carried out reinforcing maintenance.
For unstability reinforced earth bulkhead, remove and rebuild new reinforced earth bulkhead preferably.But consider Retaining Wall Reinforcement
Maintenance by traffic pass through requirement limited, it is necessary to it is a kind of it is similar with former reinforced earth bulkhead operation principle, to the change of former barrier wall structure
The construction method that the small, duration is fast, traffic impact is small.
The content of the invention
The invention aims to overcome deficiency of the prior art, there is provided a kind of unstability reinforced earth bulkhead reinforces maintenance
Construction method, reduce difficulty of construction, accelerate project progress, the time needed for reducing leading, can efficiently reduce
The influence constructed to existing traffic noise prediction.
The purpose of the present invention is achieved through the following technical solutions.
A kind of unstability reinforced earth bulkhead of the invention reinforces the construction method of maintenance, comprises the following steps：
Step one, punches at existing reinforced earth bulkhead baffle plate plate angle；
Step 2, arrangement is welded with the cage bar of bracket in hole；
Step 3, injects cement mortar in the hole for arrange cage bar；
Step 4, after cement mortar is pre-hardening, second pulp feeding；
Cage bar exposed parts are installed sealing off and covering anchorage device by step 5.
The arrangement of step one mesopore uses quincuncial arrangement, average one hole of every piece of baffle plate setting.
Cage bar uses spiral in the step 2, and bracket is along cage bar spaced set.
Sealing off and covering anchorage device includes anchor plate, packing ring and nut in the step 5.
In the step 5 after the installation of sealing off and covering anchorage device, sealing off and covering anchorage device and reinforced earth bulkhead baffle plate are carried out at whitewashing
Reason, forms overall.
Compared with prior art, the beneficial effect that technical scheme is brought is：
The present invention is placed in reinforced earth bulkhead baffle plate outside using sealing off and covering anchorage device, baffle plate is combined closely with soil nailing formation is reinforced
Entirety, make full use of existing reinforced earth retaining wall structure, reduce unstability reinforced earth bulkhead reinforce maintenance difficulty of construction, accelerate
Project progress, the time needed for considerably reducing leading, can efficiently reduce construction to existing traffic noise prediction
Influence.

Specific embodiment
For the content of the invention of the invention, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinate accompanying drawing
Describe in detail as follows.
A kind of unstability reinforced earth bulkhead of the invention reinforces the construction method of maintenance, as shown in Figures 1 to 4, including it is following
Step：
Step one, punches at the existing plate angle of reinforced earth bulkhead baffle plate 1, and the arrangement in hole uses quincuncial arrangement, puts down
Every piece baffle plate 1 sets a hole；
Step 2, arrangement is welded with the lengthways main steel bar 2 of bracket 7 in hole, and main ribs 2 and the angle of horizontal plane be 10 °~
20 °, main ribs 2 use Φ 25HRB400 spirals, bracket 7 along the spaced set of cage bar 2, with the access aperture of cage bar 2
In, for supporting cage bar 2；
Step 3, injects cement mortar 6 in the hole for arranging cage bar 2；
Step 4, after after the initial set of cement mortar 6, second pulp feeding, cement mortar 6 and cage bar 2 collectively form reinforcing soil nailing；
The exposed parts of cage bar 2 on reinforced earth bulkhead baffle plate 1, are installed sealing off and covering anchorage device, the sealing off and covering anchorage device bag by step 5
Anchor plate 3, packing ring 4 and nut 5 are included, the anchor plate 3 is made of steel plate；After the sealing off and covering anchorage device installation, to sealing off and covering anchorage
Device and reinforced earth bulkhead baffle plate 1 carry out whitewashing treatment so that sealing off and covering anchorage device and reinforced earth bulkhead baffle plate 1 are connected as entirety, use
In meeting its integrally-built requirement.
Although being described to function of the invention and the course of work above in conjunction with accompanying drawing, the invention is not limited in
Above-mentioned concrete function and the course of work, above-mentioned specific embodiment are only schematical, rather than restricted, ability
The those of ordinary skill in domain is not departing from present inventive concept and scope of the claimed protection situation under enlightenment of the invention
Under, many forms can also be made, these are belonged within protection of the invention.
