Abstract

The utility model discloses a double-row pile foundation pit support structure, which is simple and fast in construction, controllable in quality and low in engineering manufacturing cost. The double-row pile foundation pit support structure comprises two rows of piles which are parallel to each other, the top of each row of piles is provided with a ring beam, the two rows of piles are connected via connecting beams, and the two rows of piles are prestressed concrete tubular piles.

Description

A kind of double-row pile foundation pit supporting construction

Technical field

The utility model relates to a kind of foundation pit supporting construction, relates in particular to a kind of double-row pile foundation pit supporting construction.

Background technology

Retaining Structure with Double-row Piles is meant the parallel stake of two rows, the rectangular or quincuncial arrangement of front and back two campshed pile bodies is set in foundation soil.On two campsheds top collar tie beam is set, and connects with the contact beam.Along hole wall parallel direction, form door figure space structure.This structure is the space statically-indeterminate structure, and integral rigidity is big, can effectively limit foundation pit deformation.Under external load effect complicated and changeable, can adjust the internal force of supporting and protection structure itself automatically, make it to adapt to complicated and often unpredicted loading condition.

Traditional double-row pile generally adopts bored pile.Bored pile has the bearing capacity height, can passing through various complicated soil properties or soft or hard, to change big soil layer (as the rock stratum of all kinds of cohesive soils, sand, crushed gravel soil, decomposed rock and many interlayers), construction technology ripe and to advantages such as the surrounding buildings influence are little.But bored pile has simultaneously, and construction link is more, technical requirements is high, technology is complicated, construction and shortcomings such as curing time length, cost height.

The utility model content

Technical problem to be solved in the utility model provides a kind of simple and fast of constructing, system easy to control the quality, double-row pile foundation pit supporting construction that construction costs is cheap.

The utility model comprises two campsheds that are parallel to each other, and the stake top of described every campshed is provided with collar tie beam, and two campsheds connect by the contact beam, and described two campsheds are prestressed concrete pipe piles.

Stake footpath in the above-mentioned double-row pile foundation pit supporting construction is 400mm~600mm, and pile spacing is 2.5 times of stake footpaths, and array pitch is 3~5 times of stake footpaths.

The space truss structure of being made up of double prestressed concrete pipe pile is applicable to weak soil and various soil condition, and its integral rigidity is big, can effectively control foundation pit deformation, reduces the pile body moment of flexure.And the construction simple and fast of prestressed concrete pipe pile, system easy to control the quality, construction costs are cheap.

Description of drawings

Fig. 1 is the schematic diagram of double-row pile foundation pit supporting construction.

The specific embodiment

As shown in Figure 1, the double-row pile foundation pit supporting construction in the present embodiment comprises first row's prestressed concrete pipe pile 1 and second row's prestressed concrete pipe pile 2, and above-mentioned two row's prestressed concrete pipe piles are parallel to each other.

The stake top that first collar tie beam, 3, the second row's prestressed concrete pipe piles 2 are set on the stake top of above-mentioned first row's prestressed concrete pipe pile 1 is provided with second collar tie beam 4.Above-mentioned two row's prestressed concrete pipe piles connect by contact beam 5.

Claims (2)

1. a double-row pile foundation pit supporting construction comprises two campsheds that are parallel to each other, and the stake top of described every campshed is provided with collar tie beam, and two campsheds connect by the contact beam, and it is characterized in that: described two campsheds are prestressed concrete pipe piles.
2. double-row pile foundation pit supporting construction according to claim 1 is characterized in that: the stake footpath is 400mm~600mm, and pile spacing is 2.5 times of stake footpaths, and array pitch is 3~5 times of stake footpaths.
