Abstract
The invention involves a method used to build a kind of blocking soil wall by use of inner anchor wall. One or multi anchor walls are built within blocked soil mass to provide stretching resistance for anchor rod and anchor line. The inner anchor wall, anchor rod and anchor line, outer locking wall together form a blocking soil wall to clamp blocked soil mass. The outer blocking wall is mainly made from stirred cement pile. The inner anchor wall is mainly made from vertical steel pile, from horizontal seizing & expanding dish supporting pile or horizontal stirred cement pile. Because of easy and simple construction of the inner anchor wall, high anchor-hold of the ground anchor and being reused of the anchor rod and the anchor line, the cost is lowered to 50% and constructing time is shortened to half period of original one. Moreover, the stress situation is clear and designing calculation is simplified for such form of structure.
Description
The present invention relates to field of civil engineering, particularly the soil body supporting field of foundation ditch and side slope.
The retaining wall that tradition has earth anchor and soil nailing has following shortcoming: 1. cost height, and many anchor poles (rope) can not reclaim, and the grouting cement amount is very big; Engineering time long, manufacturing an anchor pole (rope) approximately needed more than 3 hours, to consume man-hour also longer; 3. designing and calculating complexity; 4. because the uplift resistance that single anchor pole (rope) is provided is little, so the anchor pole consumption is many; 5. quality is wayward, is easier to that accidents happened.
The objective of the invention is to: provide a kind of retaining wall method for production that interior anchor wall is arranged in order to overcome above-mentioned deficiency.This method simplicity of design and construction can reduce cost and reduction of erection time easily greatly when guaranteeing quality.
Purpose of the present invention reaches by following measure: a kind of retaining wall method for production that interior anchor wall is arranged, according to different operating modes, the intersection time is manufactured the outer barricade 1 that can keep off soil at the same time or successively, cut out or layering cuts out the soil body 2 of (or side slope is outer) in the foundation ditch, be arranged on by anchor pole, rope 4 in the supporting soil body 3, it is characterized in that: same time or the front and back of stating action on the implementation intersect the time, manufacture by anchor wall 5 in the supporting soil body 3 one or more surfaces, multilayer anchor pole, rope 4 connect outer barricade 1 and interior anchor walls 5.Interior anchor wall 5 provides effective anti-drag anchoring power for anchor pole, rope 4, clamps by the retaining wall of the wall-anchor of the supporting soil body 3-wall construction form by anchor wall 5 and outer barricade 1 this two face wall in usefulness of pulling force formation of anchor pole, rope 4.
Purpose of the present invention can also reach by taking following measure:
On the ground, adopt hole digging pile, drilled pile, punching stake, pipeline sinking pile, compaction pile, agitation pile, concrete preformed pile, piling bar, conventional methods such as diaphragm wall, anchor wall 5 in manufacturing from top to bottom.
Shaped steel is sunk to by in the supporting soil body 3 by root, forms discontinuous interior anchor wall 5, anchor pole, rope 4 are to pass in slit 7 between the shaped steel, the hole 8 on the shaped steel to connect with shaped steel.
Connecting piece 9 passes in the hole 8 on the shaped steel, and two adjacent shaped steel are connect mutually.
Passing outer barricade 1 enters by the supporting soil body 3, in by the supporting soil body 3, put into explosive or pressure fluid or squeezed facility 11, utilize the pressure or the fluid pressure of blast then or mechanical pressure is squeezed is formed soil body cavitys by the supporting soil body 3, in soil body cavity, inject the mixture that contains cement or lime or water glass form in anchor wall 5.
In by the soil body cavity of squeezed formation, put into open umbrella stand formula muscle cage 10 of energy and cloth capsule, umbrella stand formula muscle cage 10 connects with anchor pole, rope 4.Umbrella stand formula muscle cage 9 has increased the anchoring ability with back anchor wall 5, and the material of anchor wall 5 mixed in the cloth capsule stoped diffusing soil and manufactures.
After the retaining wall function was finished, the shaped steel that interior anchor wall 5 adopts and anchor pole, rope 4 were taken out to transfer to reclaim and are used.
The invention has the advantages that the anti-power of dialling of earth anchor improves and reduced quantity owing to increased interior anchor wall, most steel of anchor wall can reclaim in the while.This two aspect has reduced the cost of retaining wall effectively and has shortened the engineering time.Interior exterior wall folder soil structure form is stressed short and sweet, calculates and has also simplified.Interior anchor wall job practices is simple, and quality has also had assurance.
Describe the present invention below in conjunction with accompanying drawing:
Fig. 1 is the vertical cross section schematic diagram of the embodiment of the invention 1
Fig. 2 is that the level of the embodiment of the invention 1 is to generalized section
Fig. 3 is that the interior anchor wall level of the embodiment of the invention 2 is to generalized section
Fig. 4 is the interior anchor wall vertical cross section schematic diagram of the embodiment of the invention 3 and embodiment 4
As depicted in figs. 1 and 2, the content of present embodiment 1 and step are as follows:
Adopt paddling process to form the outer barricade 1 of cement-soil on the ground, the vertical tensile strength of channel-section steel with the increase cement-soil is inserted in the outside of barricade outside, the soil body 2 in the stage excavation foundation ditch, and the method that pierces forms anchor hole 6 and waist rail is set, and forms outer barricade 1; At the same time, sink to by the discrete interior anchor wall 5 of formation one side in the soil body 3 of supporting with steel pipe, discharge the soil body in the steel pipe, from anchor hole 6, deliver between two steel pipes head collar of anchor cable 4, again with a thin rod iron or steel pipe as connecting piece 9 from two adjacent steel pipes hole 8 and the head collar of anchor cable 4 pass in the lump, adjacent two steel pipes and anchor cable 4 anchorings are connect, again the waist rail anchoring connection in the afterbody of anchor cable 4 and the outer barricade outside and apply prestressing force; Down successively construct to the foundation ditch bottom, clamp by the order ground of the supporting soil body 3 by anchor cable 4, formed the gravity retaining wall of a joist anchor wall construction form thereby reach with outer barricade 1 and interior anchor wall 5 by above-mentioned processing step circulation.
As shown in Figure 3, the content of present embodiment 2 and step are as follows:
With channel-section steel or i iron or steel sheet pile replace steel pipe manufacture in anchor wall 5, have pair head of barb-like anchor cable 4 to pass the narrow gap 7 of vertical plane appearance mode between adjacent two i iron or channel-section steel or steel sheet pile, revolve and be horizontal plane after turning 90 degrees and connect mutually with the edge of a wing of two i iron or channel-section steel or steel sheet pile, the head of anchor cable 4 tightly hooks i iron or channel-section steel or steel sheet pile when prestressed stretch-draw like this, and other content and step are with embodiment 1.
As shown in Figure 4, the content of present embodiment 3 and step are as follows:
In established anchor hole 6, put into squeezed facility 11, squeezed facility 11 are through repeatedly squeezed and rotation, in by the supporting soil body 3, form a garden disc type cavity more much bigger than anchor hole 6, take out squeezed facility 11, in cavity, put into umbrella stand formula reinforcing cage 10 and cloth capsule, reinforcing cage 10 connects mutually with anchor cable 4, be surrounded by and the close cloth capsule of cavity volume size in its outside, open reinforcing cage 10, concrete that injects by anchor hole 6 pressure or cement mortar or cement paste have been full of whole cloth capsule, fixed back forms a discrete interior anchor wall 5 of garden dish type that volume is bigger, and other content and step are with embodiment 1 and embodiment 2.Present embodiment 3 is exactly in fact that vertical dish extruded and extended pile method become a laterally dish extruded and extended pile method.
As shown in Figure 4, content of this example 4 and step are as follows:
